Introduction The VITEK 2 System is an automated microbiology platform designed for the rapid identification (ID) and antimicrobial susceptibility testing (AST) of a wide range of microorganisms. It utilizes miniaturized, closed cards that enhance lab safety and streamline workflow. The VITEK 2 cards are lightweight, …
Introduction As of May 7, 2026, international health authorities are responding to a rare and deadly hantavirus outbreak aboard the Dutch expedition cruise ship MV Hondius. The outbreak is specifically linked to the Andes strain, which is notable for being the only hantavirus variety capable …
Introduction First-Line Drug Susceptibility Testing (FL-DST or sometimes referred to in context as SL-DST when covering all first-line agents: Rifampicin, Isoniazid, Ethambutol, Pyrazinamide) is a crucial laboratory procedure used to determine if a patient’s Mycobacterium tuberculosis (Mtb) strain is sensitive or resistant to primary anti-TB …
Introduction Hantaviruses are a group of rodent-borne viruses that cause two main life-threatening diseases in humans: Hantavirus Pulmonary Syndrome (HPS) and Hemorrhagic Fever with Renal Syndrome (HFRS). Unlike many other bunyaviruses, they are not transmitted by insects but primarily through the inhalation of aerosolized rodent …
Red Sore on Inner Lip The image shows a red, oval lesion on the inner lower lip with a small white center, surrounded by an area of inflammation. Common Oral Conditions This visual description is consistent with common oral conditions such as: Common Care Options …
Introduction The Xpert MTB/RIF assay is an automated, cartridge-based molecular test used to detect Mycobacterium tuberculosis (MTB) and rifampicin (RIF) resistance, the most potent first-line anti-TB drug. Endorsed by the WHO in 2010, the Xpert MTB/RIF assay revolutionized TB diagnosis by providing results in less than two …
Introduction of Bacterial Load (Decoding the CFU) Bacterial load, measured in Colony-Forming Units (CFU), is a fundamental concept in microbiology used to estimate the number of viable (living) microorganisms in a sample. Unlike total cell counts that include dead bacteria, the CFU method only counts …
Introduction Lowenstein-Jensen (L-J) medium is the gold standard for the cultivation of Mycobacterium tuberculosis. However, because it is an egg-based, non-selective (or semi-selective) medium that requires long incubation periods, it is highly susceptible to contamination. L-J medium is rich in nutrients (eggs, glycerol, potato flour), …
