Quality control strains (standard strains) are well-characterized microorganisms with defined susceptibility or resistance profiles to the antimicrobial agent(s) tested. They are routinely used to standardize the antibiotic susceptibility testing (AST) methodologies and to check the […]
Scrub typhus also known as bush typhus, is an emerging infectious disease caused by a bacteria called Orientia tsutsugamushi (formerly known as Rickettsia tsutsugamushi). It is a zoonotic disease primarily affecting rodents, rabbits, and marsupials. Humans […]
Last updated on June 21st, 2021ESBL stands for extended-spectrum beta-lactamases, i.e. a group of enzymes produced by both Gram-negative and Gram-positive bacteria which can hydrolyze all β- lactam agents except carbapenems and cephamycins. ESBLs belong […]
Last updated on June 14th, 2021Mucormycosis is a rare and life-threatening fungal disease caused by a group of fungi collectively known as mucormycetes. Since the disease is very fatal, timely diagnosis is crucial for treatment, […]
Last updated on June 25th, 2021Enterococci are catalase negative, gram-positive cocci in chains. Initially grouped under group D Streptococcus, they are reclassified later as a separate genus Enterococcus under a family; Enterococcaceae. Enterococcus faecalis and […]
Last updated on May 28th, 2021Mucormycosis, previously called ‘zygomycosis’, also known as ‘black fungus disease ‘in online or print media after its epidemic in India during the COVID-19 pandemic, is a serious but rare fungal […]
Last updated on June 21st, 2021The enzyme carbapenemase can be detected by various phenotypic and molecular methods. Phenotypic methods for carbapenemases detection are preferred over molecular techniques because they are rapid, affordable, accurate, and feasible […]
Last updated on June 21st, 2021Bordetella pertussis is a small Gram-negative coccobacillus. It is the causative agent of whooping cough (pertussis), an acute respiratory infection most common in children. Two species, B. pertussis and B. parapertussis cause […]
Last updated on July 4th, 2021Southern blotting is a molecular technique to find target DNA sequences in a sample. It is a multi-step process, that begins with the electrophoresis of DNA, transfer of DNA fragments […]
Last updated on June 21st, 2021The Carba NP test (CNPt) is a biochemical test for the rapid detection (≤2 h) of carbapenemase production in Gram-negative bacilli. Clinical and Laboratory Standards Institute (CLSI) recommends Carba NP […]
Last updated on June 21st, 2021Neisseria meningitidis also referred to as meningococci are fastidious, aerobic Gram-negative diplococci with adjacent sides flattened (lens-shape/half-moon-shaped). Though it is a commensal of nasopharynx for immunocompetent individuals, it may cause […]
Last updated on July 4th, 2021Macrolides are primarily bacteriostatic antibacterial agents that inhibit bacterial protein synthesis by binding with 50S subunit of the ribosome. Members of the group include erythromycin, azithromycin, clarithromycin, roxithromycin, dirithromycin, and telithromycin. […]
