Proteus penneri– Introduction, Morphology, Pathogenicity, Lab Diagnosis, Treatment, Prevention, and Keynote
Introduction Proteus penneri is a Gram-negative bacterium primarily found in soil and water. It belongs to the family Enterobacteriaceae, closely related to Proteus mirabilis. However, it differs from P. mirabilis in its biochemical behavior and antibiotic resistance. Additionally, P. penneri frequently causes infections in humans, especially urinary tract infections. This bacterium is less common than P. mirabilis, yet its clinical significance is growing. Importantly, it has shown resistance to certain antibiotics, making treatment challenging. Moreover, P....
Streptococcus gallolyticus – Introduction, Morphology, Pathogenicity, Lab Diagnosis, Treatment, Prevention, and Keynote
Introduction Streptococcus gallolyticus is a Gram-positive bacterium often associated with infective endocarditis and colorectal cancer. It primarily colonizes the gastrointestinal tract, yet it can enter the bloodstream, leading to serious infections. Moreover, this bacterium is particularly adept at adhering to heart valves, making it a significant cause of endocarditis. In fact, patients with Streptococcus gallolyticus bacteremia often require thorough colorectal screening, as the bacterium is closely linked to malignancies in that region. Besides, its ability to...
Rose Bengal Agar (RBA)- Introduction, Principle, Composition, Test Procedure, Colony Characteristics, Uses, and Keynotes
Introduction Rose Bengal Agar (RBA) is a selective medium used for isolating fungi. It contains rose bengal dye, which inhibits bacterial growth. This medium supports the growth of many fungi. Rose Bengal Agar includes chloramphenicol, which further suppresses bacterial contamination. It is especially useful in environmental and clinical mycology. Fungal colonies appear distinct and colorful on this medium. The dye also restricts the spread of colonies, aiding in identification. Scientists use RBA to study fungal diversity....
