SARS-CoV-2 IgG/IgM rapid test is a lateral flow immunoassay intended for the qualitative detection of IgM and IgG antibodies to SARS-CoV-2 in the blood (serum, plasma) from patients suspected of COVID-19. The SARS-CoV-2 IgG/IgM rapid [...] -
Nasopharyngeal (NP) swab is the optimal upper respiratory tract specimen collection method for viral respiratory infections such as respiratory syncytial virus (RSV), SARS-CoV-2, influenza virus A & B, and parainfluenza virus. Nasopharyngeal swabs are also [...] -
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 [...] -
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 [...] -
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 [...] -
There are basically three ways to stop infectious diseases like covid19, one involves the interruption of transmission by using extraordinary restrictions including social distancing, another is vaccination (vaccine is in developing phase for Covid19), and [...] -
Neisseria 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 sepsis and meningococcal meningitis in [...] -
Macrolides 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. Macrolides were originally derived from [...] -
Tetracyclines Tetracyclines are a group of broad-spectrum antibiotics effective against a wide range of Gram-positive, Gram-negative bacteria, and several intracellular bacterial pathogens such as chlamydia, rickettsia, mycoplasma, etc. Tetracyclines are usually considered as bacteriostatic antibiotics. [...] -
Bacteriophages “bacteria-eater” are infectious agents that replicate as obligate intracellular parasites in bacteria with high selectivity. They are the powerful regulators of bacterial populations in natural ecosystems and are found in the soils, plants, rivers, [...] -
Nocardia species are gram-positive, variably acid-fast, filamentous, and strictly aerobic organisms belonging to the actinomycetes group. Nocardia spp form branched filaments that extend along the surface (substrate hyphae) and into the air (aerial hyphae). Filamentous [...]
