Rapid collection and testing of appropriate specimens from patients meeting the suspected case definition for COVID-19 is a must for outbreak control and clinical management. Molecular testing is the current recommended method for the identification […]
Immunochromatography is a combination of chromatography and immunoassay. This technology is in use to a wide array of tests for clinical, veterinary, and industrial applications. Depending on the assay, either antigen (for detection of antibody) […]
SARS-CoV-2 is a novel virus that first appeared in Wuhan, China, in December 2019. It is a member of the Coronaviridae family, so named for their “crown-like” appearance. It is a large family of viruses […]
Viral Transport Media (VTM) are suitable for collection, transport, maintenance and long-term freeze storage of clinical specimens containing viruses, chlamydia, mycoplasma or ureaplasma organisms. It maintains organism viability for 48 hours at room or refrigerated […]
Cepheid, one of the leading molecular diagnostic companies, which is also the manufacturer of GeneXpert System, has received emergency use authorization (EUA) from FDA for its rapid SARS-CoV-2 test kit. This automated molecular test for […]
Detection of specific antigens present in the sample (blood, urine, CSF or stool) using immunologic methods such as precipitin tests, particle agglutination tests, immunofluorescence, immunochromatographic or enzyme immunoassays are the mainstay for the rapid diagnosis […]
Bacteriophage “bacteria eaters” are infectious agents that replicate as obligate intracellular parasites in bacteria but in extracellular environment they are metabolically inert. A typical phage contains “head” (containing DNA embedded in a protein envelope), “neck”and […]
Respiratory Syncytial Virus (RSV), is a member of the Pneumovirus genus within the family Paramyxoviridae. RSV usually causes mild, cold-like symptoms. Most people recover in a week or two, but RSV can be serious, especially for infants and older […]
Cell culture refers to the process by which cells are grown in a controlled artificial environment. Cells can be maintained in vitro outside of their original body by this process which is quite simple compared […]
The term “blotting” refers to the transfer of biological samples from a gel to a membrane and their subsequent detection on the surface of the membrane. Southern blot is used for transferring DNA, Northern blot […]
Science is not perfect nor does all those breakthrough discoveries. Those beliefs that we have right now about a particular thing, person, event or discovery may change anytime soon, if a new research gives sufficient evidence […]
The Baltimore system of virus classification devised by virologist & Nobel laureate David Baltimore is based on the genomic nature of the viruses. The central theme of the Baltimore system of virus classification is ‘all viruses must […]
