The principle, primer design, the amplification process, and the general advantages and limitations of the multiplex method are covered in our article on [multiplex PCR](https:\u002F\u002Fmicrobeonline.com\u002Fmultiplex-pcr-principle-applications-and-limitations\u002F). If you are new to the technique, read that first, then come back here for the clinical applications.\n\nOne quick recap, because everything below depends on it. In ordinary (singleplex) PCR, one reaction looks for one target. In multiplex PCR, one reaction uses several primer pairs and looks for many targets at once. For RNA viruses, a reverse-transcription step first converts RNA into DNA, then amplification proceeds as usual. The output is a list: for each target the panel was designed to find, the report says detected or not detected.\n\n### The core idea: from \"one organism at a time\" to \"one syndrome at a time\"\n\nThis is the single most important use of multiplex PCR.\n\nThe old diagnostic approach starts with a *suspected organism*. The clinician asks \"could this be influenza?\" and orders an influenza test. If that is negative and the patient is still sick, they ask the next question and order the next test. Testing proceeds one organism at a time.\n\n**The multiplex approach starts with a *clinical syndrome*.** Many different pathogens can produce the same clinical picture. Fever with cough could be any of a dozen respiratory viruses and a few bacteria. Acute diarrhea could be bacterial, viral, or parasitic. So **instead of guessing which organism to test for, the lab tests for the whole group of pathogens known to cause that syndrome,** from a single specimen, in one run.\n\nThe workflow becomes:\n\n**Clinical syndrome → appropriate specimen → multiplex panel → several targets checked at once → interpretation**\n\nrather than:\n\n**Suspected organism → single test → (if negative) next suspected organism → next test**\n\nThis is called *syndromic testing*, and it is the reason multiplex panels have spread so quickly through clinical microbiology. The rest of this article walks through the major syndromes, then, more importantly, how to read what comes back.\n\n### A note on how these panels look at the bench\n\nMost clinical syndromic panels today are *cartridge-based* systems. The specimen is added to a single sealed cartridge or pouch that already contains all the reagents. The cartridge goes into an instrument that does the extraction, amplification, and detection automatically, and prints a result. The staff time involved is only a few minutes; the machine does the rest, usually in about an hour.\n\nSeveral companies make these systems, and a student will meet different brands in different labs. The most widely used include the bioMérieux BioFire FilmArray, the QIAGEN QIAstat-Dx, and the Roche (GenMark) ePlex, among others.\n\nThey differ in exact target lists and some performance details, but the concept, the workflow, and the way results are interpreted are the same across all of them. Throughout this article the teaching is about the *category*; brand names appear only as concrete examples so the systems are recognizable at the bench. The exact pathogens on any given panel depend on the assay and its version, which the manufacturers update over time, so always check the current package insert for the panel your lab runs.\n\nFor each syndrome below, the pattern is the same: what the patient looks like, a representative (not exhaustive) list of target organisms, what a result changes, and the interpretive trap to watch for. The traps are the part worth memorizing.\n\n### 1. Respiratory panels\n\n**The patient:** fever, cough, sore throat, runny nose, wheeze, shortness of breath, or pneumonia. Many pathogens produce this picture and clinical features alone rarely separate them.\n\n**Representative targets:** influenza A and B, respiratory syncytial virus, SARS-CoV-2, parainfluenza viruses, human metapneumovirus, adenovirus, rhinovirus\u002Fenterovirus, and the seasonal coronaviruses, plus a few bacteria that cause atypical pneumonia such as *Mycoplasma pneumoniae*, *Chlamydophila pneumoniae*, and *Bordetella pertussis*. The exact list varies by panel.\n\n**What a result changes:** it can guide treatment (start an antiviral, or stop an unnecessary antibiotic when a virus is found), guide infection control (isolate, and cohort patients with the same virus), and feed surveillance data on what is circulating.\n\n**The trap:** rhinovirus and enterovirus can be detected for weeks after the illness has resolved, because their RNA lingers. A positive rhinovirus in a patient whose symptoms started a month ago may be a leftover, not the current problem. And detecting a virus does not rule out a bacterial co-infection that the panel was not designed to find. A positive is an explanation to weigh, not always *the* explanation.\n\n### 2. Gastrointestinal (GI) panels\n\n**The patient:** acute diarrhea, sometimes with vomiting, fever, or blood in the stool, especially after suspect food or during an outbreak.\n\n**Representative targets:** bacteria such as *Salmonella*, *Shigella*, *Campylobacter*, diarrheagenic *Escherichia coli* types, and *Vibrio*; viruses such as norovirus, rotavirus, and enteric adenovirus; and parasites such as *Giardia*, *Cryptosporidium*, and *Entamoeba histolytica*. A single stool sample can be tested for all of them at once.\n\n**What a result changes:** it can shorten the time to a specific diagnosis, reduce unnecessary empiric antibiotics, shorten isolation, and, during an outbreak, quickly point public-health investigators to the cause.\n\n**The trap, and it is a big one: *Clostridioides difficile*.** Many GI panels include a *C. difficile* target. But a large fraction of healthy adults, and a very large fraction of infants and toddlers, carry *C. difficile* in the gut without disease. The panel detects the gene; it cannot tell colonization from true infection. A positive *C. difficile* in someone without genuine *C. difficile*-type illness, or in a patient whose diarrhea is better explained by laxatives, can lead to treatment the patient never needed. This problem is real enough that many hospitals have deliberately stopped reporting the *C. difficile* result from their GI panel, and instead ask clinicians to order dedicated *C. difficile* testing (which combines antigen and toxin detection) when that infection is actually suspected. This one example teaches the whole lesson of the article: **a detected gene is not automatically a disease.**\n\nA second GI trap: the panel is very sensitive and can report several organisms at once. More than one positive may mean true co-infection, or it may mean one true pathogen plus one harmless passenger. The clinical picture decides which.\n\n### 3. Central nervous system (meningitis\u002Fencephalitis) panels\n\n**The patient:** fever, severe headache, neck stiffness, altered consciousness, or seizures. These infections can worsen within hours, so speed matters more here than almost anywhere else.\n\n**Representative targets:** bacteria such as *Streptococcus pneumoniae*, *Neisseria meningitidis*, *Haemophilus influenzae*, *Streptococcus agalactiae* (group B strep), and *Listeria monocytogenes*; viruses such as HSV-1, HSV-2, varicella-zoster virus, and enterovirus; and, on some panels, *Cryptococcus*.\n\n**What a result changes:** a rapid pathogen name on cerebrospinal fluid can direct or narrow therapy hours earlier than culture, which is genuinely life-saving in this syndrome.\n\n**The trap:** the panel does not replace the rest of the CSF workup. Cell count, protein, glucose, Gram stain, opening pressure, and culture all still matter, and culture is still what gives you a full antibiotic susceptibility result. Just as important: a negative panel does not exclude meningitis. If the clinical picture says meningitis, the patient is treated regardless of a negative panel, because the pathogen may be one the panel does not cover, or present below the level it can detect. The panel adds speed; it does not remove clinical judgment.\n\n### 4. Sexually transmitted infection panels\n\n**The patient:** urethral or vaginal discharge, painful urination, cervicitis, or pelvic inflammatory disease. Different organisms produce overlapping symptoms.\n\n**Representative targets:** *Chlamydia trachomatis*, *Neisseria gonorrhoeae*, *Trichomonas vaginalis*, and *Mycoplasma genitalium*.\n\n**What a result changes:** testing several likely organisms from one specimen is efficient and lets treatment match the actual organism rather than a guess, which also supports correct partner management.\n\n**The trap:** these are nucleic acid tests, so they detect the organism's genetic material, not a live, culturable organism. That matters for one specific situation: a *test of cure* done too soon after treatment can stay positive from residual nucleic acid even when the infection is gone. Follow the recommended waiting interval before retesting.\n\n### 5. Bloodstream infection panels\n\n**The patient:** fever, low blood pressure, suspected sepsis. Blood cultures are drawn, but conventional identification and susceptibility testing from a positive bottle takes a day or more.\n\n**How these panels differ from the others:** they are usually run *on a blood-culture bottle that has already flagged positive*, not directly on the patient's blood. The blood culture still has to grow first. What the panel does is compress the slow downstream steps, identifying the organism and checking for selected resistance genes within about an hour of the bottle turning positive, instead of waiting for subculture and biochemical identification.\n\n**Representative targets:** common bloodstream organisms such as *Staphylococcus aureus*, *Enterococcus* species, *Escherichia coli*, *Klebsiella pneumoniae*, *Pseudomonas aeruginosa*, and selected *Candida* species, plus selected resistance markers (discussed in the next section).\n\n**What a result changes:** knowing within an hour that a positive bottle contains *S. aureus* rather than a skin contaminant, or that it carries a methicillin-resistance gene, can move therapy in the right direction far sooner. For a septic patient, hours count.\n\n**The trap:** the panel identifies what is in the bottle, and the bottle can contain more than the patient's true pathogen. A documented real-world example: some blood-culture bottles have contained trace yeast DNA in the culture medium itself, which caused panels to report *Candida tropicalis* from bottles where no *Candida* was actually present, confirmed when culture grew only the bacterium. The lesson is that the panel result is read alongside the Gram stain and the clinical picture, and confirmed by culture, not acted on blindly. Detection of DNA in a bottle is a strong lead, not a final answer.\n\n### Detecting antimicrobial resistance markers\n\nOne of the most useful additions to these panels is the ability to detect selected resistance *genes* alongside the organism. Depending on the panel, targets may include *mecA\u002FmecC* (methicillin resistance in staphylococci), *vanA\u002FvanB* (vancomycin resistance in enterococci), and carbapenemase genes such as *KPC*, *NDM*, *VIM*, *IMP*, and *OXA-48-like*.\n\nThis can be powerful. A report of *Staphylococcus aureus* detected, *mecA* detected gives the team early evidence of likely MRSA, well before phenotypic testing confirms it. Detecting a carbapenemase gene raises an immediate flag for both treatment and infection control.\n\nBut this section carries the sharpest judgment point in the whole article, so read it carefully.\n\n**A resistance gene detected is not a full susceptibility test.** The panel tells you a resistance mechanism is present. It does not tell you the organism's complete susceptibility to every relevant drug, and it cannot detect resistance mechanisms it was not designed to look for. An organism can be resistant through a route the panel does not test. So molecular resistance detection *complements* phenotypic antimicrobial susceptibility testing; it does not replace it.\n\n**Gene-to-organism attribution is a second, subtler trap.** When a specimen contains more than one organism, a detected resistance gene cannot always be assigned with certainty to a specific one. Imagine a positive blood-culture bottle that grows both *S. aureus* and a coagulase-negative staphylococcus, and the panel reports *mecA* detected. The *mecA* could belong to either organism. The panel found the gene; it did not tell you which bug is carrying it. This is exactly why phenotypic testing on the isolated organism still matters.\n\n### When is a panel worth it?\n\nSyndromic panels are expensive compared with many conventional tests, and they require the instrument, the cartridges, and trained staff. In many settings, including much of South Asia, Southeast Asia, and Africa, a single cartridge can cost more than a whole conventional workup. That makes \"should we run a panel here?\" a real clinical and resource decision, not an automatic yes.\n\nTwo ideas help. First, *pretest probability*. A broad, sensitive panel used on a patient with a low chance of the disease produces more false leads than useful answers, because even a very good test throws occasional false positives, and when true disease is unlikely, a larger share of positives are false. Panels earn their cost in patients who are meaningfully likely to have the syndrome and where a fast, specific answer will change what you do. Second, *diagnostic stewardship*: ordering the panel when it will change management, not reflexively; not repeating it without a reason; and, as the *C. difficile* example showed, sometimes deliberately not reporting a target that causes more harm than good. Using these tools well is as much about restraint as reach.\n\n### How to read any multiplex PCR result: four questions\n\nA multiplex result should never be read in isolation. Whatever the panel, ask these four questions in order.\n\n**1. What was detected?** Note the organism and any resistance marker.\n\n**2. Does it fit the patient's syndrome and specimen?** A detected organism should make biological sense for this illness and this sample type. A respiratory virus fits a nasopharyngeal swab from a coughing patient; the same organism from an unusual site needs more thought.\n\n**3. Could this be colonization, carriage, or residual nucleic acid rather than active infection?** This is the question that separates a good clinician from the machine. It matters most for organisms that normally live in or on the body (*C. difficile* in the gut, many organisms on the skin) and after recent treatment, when dead-organism DNA can linger.\n\n**4. Does it change management?** Will it alter antimicrobial or antiviral therapy, isolation, infection control, further testing, or a public-health response? If a result would not change anything, it may not have been worth ordering, which loops back to stewardship.\n\nThe best interpretation combines all of it:\n\n**Multiplex PCR result + clinical picture + specimen type + epidemiology + other lab results (Gram stain, culture, cell counts, and so on)**\n\n### The honest limits of multiplex panels\n\nGathering the traps above into one place, because these are what students most often miss:\n\n- **A panel only finds what it was designed to find.** Panel negative does not mean no infection. The pathogen may simply not be on the panel.\n- **Detection is not causation.** Finding a microbe's nucleic acid does not prove it is causing this illness, especially for organisms that colonize the body.\n- **Detection is not viability.** PCR finds nucleic acid, which can persist after the live organism is gone. This is why tests of cure done too early can mislead.\n- **A resistance gene is not a full susceptibility profile,** and in mixed samples cannot always be tied to a specific organism.\n- **Multiple positives can be hard to read:** true co-infection, colonization plus infection, or an incidental finding. Only the clinical picture resolves it.\n- **Cost and access are real,** and panels are not available or affordable everywhere.\n\nNone of this makes multiplex panels bad. It makes them powerful tools that require a thinking clinician. The panel supplies data faster than ever before; turning data into a diagnosis is still a human job.\n\n### Multiplex PCR and conventional microbiology: partners, not rivals\n\nIt is tempting to frame molecular panels as the replacement for culture. That is the wrong frame. The two answer different questions.\n\nCulture proves an organism is *alive*, lets you isolate it, and gives a full susceptibility profile. It can also grow something unexpected that no panel would have targeted. Its weaknesses are speed, and poor yield for fastidious or slow-growing organisms or after antibiotics have already been given.\n\nMultiplex PCR is fast, checks many targets at once from a small specimen, and works even for organisms that are hard to culture and even after some antibiotic exposure. Its weaknesses are the fixed target list, the inability to prove viability, and the limited resistance picture.\n\nPut together, they cover each other's gaps. A common modern workflow uses the panel for a fast, actionable first answer and culture for confirmation, full susceptibility testing, and anything the panel missed. Complementary, not competing.\n\n## How to Remember\n\n**Syndrome first, not organism first.** The whole idea compresses to this. Old way: pick a suspect, test for it, repeat. New way: name the syndrome, test the whole group of usual suspects at once. If you remember one sentence, remember that the question changed from \"is it this organism?\" to \"which of the organisms that cause this syndrome is it?\"\n\n**The three \"not equals\" that catch everyone out.** Detected ≠ caused. Detected ≠ alive. Gene ≠ full susceptibility. A positive is genetic material found, nothing more, until the clinical picture tells you what it means. These three lines carry most of the article's judgment layer.\n\n**Panel negative ≠ no infection.** The panel finds only what it was built to find. A negative narrows the possibilities; it does not close the case, and a clinically obvious infection is still treated.\n\n**The *C. difficile* rule: common gene, uncommon proof.** Many people carry the *C. difficile* gene without disease, so a GI-panel positive is not automatically infection. This is why hospitals often hide that result and ask for dedicated testing. Let this stand in your memory for the whole \"detection is not disease\" idea.\n\n**Blood panels run on the bottle, not the patient.** The blood culture still has to grow first. The panel then speeds up naming what grew and checking a few resistance genes. Remembering this keeps the bloodstream panel straight from all the others, which run on the primary specimen.\n\n## Key exam facts\n\n| Fact | Detail and memory aid |\n| --- | --- |\n| Singleplex vs multiplex PCR | Singleplex: one reaction, one target. Multiplex: one reaction, many primer pairs, many targets. |\n| Syndromic testing | Start from the clinical syndrome, test the whole group of pathogens that cause it, from one specimen. The defining idea of clinical multiplex PCR. |\n| Cartridge-based systems | Sealed cartridge holds all reagents; instrument does extraction, amplification, detection automatically; result in about an hour. Examples: BioFire FilmArray, QIAstat-Dx, ePlex. Concept is the same across brands. |\n| Respiratory panel trap | Rhinovirus\u002Fenterovirus RNA can persist for weeks after recovery. A positive may be residual, not the current cause. |\n| GI panel trap (*C. difficile*) | *C. difficile* is commonly carried without disease. Panel detects the gene, not the disease. Many hospitals suppress this result and use dedicated *C. difficile* testing instead. |\n| CNS panel rule | Does not replace CSF cell count, protein, glucose, Gram stain, or culture. A negative panel does not exclude meningitis; treat on clinical grounds. |\n| STI panel trap | Detects nucleic acid, not live organism. Test of cure done too early can stay falsely positive. |\n| Bloodstream panel | Runs on an already-positive blood-culture bottle, not the patient's blood directly. Speeds up ID and resistance-gene detection after growth. |\n| Bloodstream panel trap | The bottle can contain contaminant DNA (documented *Candida tropicalis* false positives from yeast DNA in media). Confirm with Gram stain, clinical picture, and culture. |\n| Resistance markers | *mecA\u002FmecC* (MRSA), *vanA\u002FvanB* (VRE), carbapenemases (*KPC, NDM, VIM, IMP, OXA-48-like*). Fast flags for resistance and infection control. |\n| Resistance limitation | A gene detected is not a full susceptibility test, and in mixed samples cannot always be assigned to one organism. Phenotypic AST still needed. |\n| The three \"not equals\" | Detected ≠ caused; detected ≠ viable; gene detected ≠ full susceptibility. |\n| Panel negative | Does not exclude infection. The pathogen may not be on the panel. |\n| Pretest probability | In low-probability patients, more positives are false. Panels earn their cost where the syndrome is genuinely likely and speed changes management. |\n| Diagnostic stewardship | Order when it changes management, do not repeat without reason, sometimes deliberately do not report a target (e.g. *C. difficile*). Restraint as much as reach. |\n| Relation to culture | Complementary. Culture proves viability, isolates the organism, gives full AST, and can catch the unexpected. Panels are faster and broader per run. |\n\n## Where Students Get Confused\n\n**\"A positive panel means the patient has that infection.\"** Not on its own. The panel found the organism's nucleic acid. Whether that organism is causing the illness depends on the syndrome, the specimen, whether the organism is a normal colonizer, and recent treatment. Detection is the start of the question, not the answer.\n\n**\"A negative panel rules out infection.\"** No. The panel only tests for the targets it was designed to find. If the true pathogen is not on the panel, or is present below the level the panel can detect, the panel is negative while the infection is real. A clinically obvious infection is treated regardless.\n\n**\"PCR detected it, so the organism is alive and active.\"** PCR detects nucleic acid, which can persist after the organism is dead or cleared. This is why a test of cure done too soon can stay positive, and why lingering viral RNA can show up long after recovery. Detection is not proof of a live, active organism.\n\n**\"A resistance gene report is the same as a susceptibility test.\"** It is not. Reporting *mecA* tells you a methicillin-resistance mechanism is present. It does not give the organism's full susceptibility across all relevant drugs, and it misses resistance mechanisms the panel does not target. Phenotypic susceptibility testing is still required for the complete picture.\n\n**\"If the GI panel says *C. difficile*, treat for *C. difficile*.\"** This is the classic error. Many people, especially young children, carry *C. difficile* without disease, and the panel cannot tell carriage from infection. Treatment decisions need the clinical picture and, usually, dedicated *C. difficile* testing. This is why many labs deliberately do not report the *C. difficile* result from the GI panel at all.\n\n**\"The bloodstream panel is run on the patient's blood, like a super-fast blood culture.\"** No. It runs on a blood-culture bottle that has *already* turned positive. The culture must grow first. The panel then speeds up identifying what grew and checking a few resistance genes. It shortens the back half of the workflow, not the growth step.\n\n**\"Multiplex PCR has made culture obsolete.\"** No. Culture proves the organism is alive, provides the isolate for full susceptibility testing, and can recover organisms no panel targets. Panels are faster and check more targets per run but have a fixed target list and cannot prove viability. The two are used together.\n\n**\"More targets on the panel is always better.\"** Not necessarily. A broader, more sensitive panel used in a patient with low pretest probability produces more incidental and false-positive findings, which can lead to unnecessary treatment. Matching the test to the clinical situation matters more than raw breadth.\n\n## References\n\n- Ramanan, P., Bryson, A. L., Binnicker, M. J., Pritt, B. S., & Patel, R. (2018).

Multiplex PCR detects multiple targets (from different organisms or different genes) in the same tube, saving sample volume, reagent cost, and time. \u003C\u002Fp>\u003Cp>\u003C\u002Fp>\u003Cp>Each primer pair produces an amplicon of a specific size, allowing identification of each target by band size on gel or by probe-specific fluorescence in real-time multiplex assays.\u003C\u002Fp>",{"question":84,"answer":85},"What is the role of the internal amplification control in multiplex PCR?","\u003Cp>The internal amplification control is a primer pair directed at a sequence present in all specimens such as a universal bacterial gene or a human housekeeping gene, included in every multiplex PCR reaction. It serves as a quality gate: if the control amplicon is detected, the PCR conditions were met and a negative result for the test targets can be confidently interpreted as true negative. \u003C\u002Fp>\u003Cp>\u003C\u002Fp>\u003Cp>If the control amplicon is absent, the PCR failed, likely due to inhibitors, degraded nucleic acid, or technical error and the negative result is uninterpretable.

Key applications include: bacterial meningitis panels detecting \u003Cem>S. pneumoniae, H. influenzae\u003C\u002Fem>, and \u003Cem>N. meningitidis \u003C\u002Fem>simultaneously from CSF; respiratory virus panels detecting influenza A, influenza B, RSV, and other respiratory pathogens from nasopharyngeal swabs; gastrointestinal pathogen panels; and sexually transmitted infection panels. \u003C\u002Fp>\u003Cp>\u003C\u002Fp>\u003Cp>The BioFire FilmArray system (which combines nested, multiplex, and singleplex PCR in an automated closed pouch) is the most widely deployed commercial application.\u003C\u002Fp>",{"question":90,"answer":91},"Why is multiplex PCR challenging to optimise?","\u003Cp>Optimizing multiplex PCR is challenging because each primer pair has different ideal conditions: melting temperature, MgCl₂ requirement, and amplification efficiency. When multiple primer pairs are combined, more efficient pairs can out-compete less efficient ones, producing strong bands for some targets and weak or absent bands for others (competitive amplification). \u003C\u002Fp>\u003Cp>\u003C\u002Fp>\u003Cp>Primers from different pairs can also interact with each other, forming cross-dimers that consume reagents. Finding annealing temperature and buffer conditions that satisfy all primer pairs simultaneously requires systematic optimization (adjusting primer concentrations, MgCl₂, and cycling parameters) which becomes increasingly complex as the number of targets increases.\u003C\u002Fp>",{"question":93,"answer":94},"\u003Cp>How is multiplex PCR different from real-time (quantitative) PCR?\u003C\u002Fp>","\u003Cp>They describe different things. Multiplex means many targets are tested in one reaction. Real-time PCR means the product is measured as it forms, often to find out how much is present. A test can be multiplex, real-time, or both at once, so the two terms are not synonyms.\u003C\u002Fp>",{"question":96,"answer":97},"\u003Cp>What are the advantages and disadvantages of multiplex PCR?\u003C\u002Fp>","\u003Cp>The main advantages are that it detects several targets from one small sample, saving specimen volume, time, and cost, and that a built-in internal control can confirm the reaction worked so a negative result can be trusted. The main disadvantages come from combining several primer pairs in one reaction: the primers can interfere with each other, some targets can out-compete others, and the reaction takes careful optimization to balance. It works best for a limited, defined set of targets.\u003C\u002Fp>",{"question":99,"answer":100},"\u003Cp>What is the principle of multiplex PCR?\u003C\u002Fp>","\u003Cp>The principle is the same as standard PCR, with one difference: several primer pairs are added to the same reaction, and each pair binds and copies only its own target. Because all the pairs share one tube and one temperature program, they must be designed to work under the same conditions. The different products are then told apart either by their size or by a colored probe for each target.\u003C\u002Fp>",[102],"pcr-techniques",{"enabled":104,"threads":105,"total":106},true,[],0,[108,114,121,128,134,139,145,150,156,159,166],{"slug":109,"name":44,"description":110,"image":111,"body":112,"postCount":113},"acharya-tankeshwar","Editor-in-chief","https:\u002F\u002Fassets.microbeonline.com\u002Fauthors\u002Ftankeshwar-acharya-author-microbeonline.jpg","***Tankeshwar Acharya, MSc (Medical Microbiology)***\n\n*Tankeshwar Acharya is an Assistant Professor in the Department of Microbiology at Patan Academy of Health Sciences (PAHS), Nepal, where he has been teaching and practicing clinical microbiology for over 14 years.
