Introduction Alcaligenes faecalis is a Gram-negative, aerobic, rod-shaped bacterium primarily found in water and soil, but also as a commensal in the human intestinal tract. While it is generally nonpathogenic, it is a significant opportunistic pathogen, particularly in hospital settings where it thrives in moist …
Introduction The system consists of an incubator-reader that can hold up to 960 culture tubes (7 ml size), allowing it to process approximately 8,000 specimens annually. It is widely considered a “gold standard” for culture-based drug susceptibility testing (DST) due to its speed and high recovery rate …
Introduction Klebsiella aerogenes (formerly Enterobacter aerogenes) is an opportunistic Gram-negative, facultative anaerobic bacterium responsible for serious healthcare-associated infections (HAIs), including bloodstream infections and pneumonia. It is highly associated with antibiotic resistance (including XDR strains) and poor clinical outcomes. Morphology Pathogenicity & Virulence Factors Lab Diagnosis Treatment Prevention Keynotes …
Introduction The VITEK MS PRIME is a benchtop, high-throughput automated identification system that works on the principle of Matrix-Assisted Laser Desorption Ionization-Time of Flight (MALDI-TOF) mass spectrometry. It is applicable to enhance laboratory workflow for the rapid identification of microbes like bacteria, yeasts, molds, and mycobacteria. Principle …
Introduction Lactococcus garvieae is a Gram-positive, catalase-negative, non-spore-forming coccus, typically arranged in pairs or short chains. It belongs to the lactic acid bacteria group and is well known as a major pathogen in fish (lactococcosis). In humans, it is an emerging opportunistic pathogen, increasingly recognized …
Introduction Bronchoalveolar lavage (BAL) is a diagnostic procedure used to collect specimens from the lower respiratory tract, particularly from the alveolar spaces. It is performed by instilling sterile saline into a segment of the lung via a bronchoscope and then aspirating it back. Gram staining …
Introduction Acinetobacter ursingii is a Gram-negative, non-fermentative, opportunistic bacterium belonging to the genus Acinetobacter. It is an uncommon species compared to Acinetobacter baumannii, but it has been increasingly recognized in healthcare-associated infections (HAIs). Reported cases include bacteremia, septicemia, pneumonia, urinary tract infections, and bloodstream infections, …
Introduction A biphasic medium is a culture system that combines both liquid (broth) and solid (agar) phases in the same container (usually a bottle or tube). It is designed to enhance microbial recovery by leveraging the advantages of both media types in one setup. Applications …
