Citrobacter farmeri – Introduction, Morphology, Pathogenicity, Lab Diagnosis, Treatment, Prevention, and Keynotes
Introduction Citrobacter farmeri is a Gram-negative, facultatively anaerobic bacterium that belongs to the Enterobacteriaceae family. Here's a brief introduction: General Characteristics Morphology and Staining: Rod-shaped bacterium that is Gram-negative. Oxygen Requirements: Facultatively anaerobic, meaning it can grow in both oxygen-rich and oxygen-deprived environments. Culture Characteristics: They usually grow on standard bacteriological media and can produce colonies that may resemble those of other Enterobacteriaceae on agar plates. Ecology and Pathogenicity Natural Habitat: Found in various environmental niches...
Pus Culture and Sensitivity Test-Introduction, Report, Clinical Significance, Common Pathogens, and Keynotes
Introduction The Pus Culture and Sensitivity Test is a diagnostic tool used primarily to identify the causative microorganism(s) of an infection and to determine their susceptibility to specific antibiotics. Pus Culture and Sensitivity Test: An Overview 1. Purpose: Identification: The test identifies which bacteria or fungus is causing an infection. Pus, which is a thick fluid containing dead tissue, bacteria, and white blood cells, is often a sign of an infection. Sensitivity: Once the causative organism...
H. influenzae – Introduction, Morphology, Pathogenicity, Lab Diagnosis, Treatment, Prevention, and Keynotes
Introduction Haemophilus influenzae (often abbreviated as H. influenzae) is a small, Gram-negative coccobacillus bacterium that can cause a variety of infections in humans. Despite its name, it does not cause influenza (the flu); influenza is caused by a virus. The name originated from initial isolation attempts during the 1892 influenza pandemic, as it was mistakenly believed to be the causative agent. Here are some key points about this bacterium: Types: H. influenzae can be categorized into...
