Sphingomonas paucimobilis-Introduction, Morphology, Pathogenicity, Lab Diagnosis, Treatment, Prevention, and Keynotes
Introduction Sphingomonas paucimobilis (formerly classified as Pseudomonas paucimobilis) is a strictly aerobic, non-fermenting, Gram-negative bacillus. It is an environmental oligotroph found widely in soil and water systems. It serves as a stealthy opportunistic pathogen in clinical settings. It can survive in nutrient-poor conditions and form …
Second-Line Drug Susceptibility Testing (SL-DST) for Tuberculosis:Introduction, Principle, Procedure, Result-Interpretation, and Keynotes
Introduction Second-line drug susceptibility testing (SL-DST) for tuberculosis is a crucial laboratory procedure designed to detect resistance to anti-TB drugs used when first-line treatment fails (i.e., multidrug-resistant TB – MDR-TB). Principle SL-DST measures the susceptibility of Mycobacterium tuberculosis to specific agents by determining the Critical …
Xpert MTB-XDR: Introduction, Principle, Procedure, Result-Interpretation, Uses, and Keynotes
Introduction The Xpert MTB/XDR assay is an advanced molecular diagnostic tool designed by Cepheid to rapidly detect Mycobacterium tuberculosis complex (MTBC) and its resistance to multiple first- and second-line drugs. Launched in 2021, it is categorized as a “low complexity” automated nucleic acid amplification test …
Mycobacterium fortuitum : Introduction, Morphology, Pathogenicity, Lab Diagnosis, Treatment, Prevention, and Keynotes
Introduction Mycobacterium fortuitum is a rapidly growing, nontuberculous mycobacterium (NTM). It is found ubiquitously in the environment, primarily associated with skin, soft tissue, and post-surgical wound infections. As an opportunistic pathogen that is known for its ability to grow within 7 days, it often causes infections …
Acinetobacter ursingii: Introduction, Morphology, Pathogenicity, Lab Diagnosis, Treatment, Prevention, and Keynote
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, …
Citrobacter werkmanii-Introduction, Morphology, Pathogenicity, Lab Diagnosis, Treatment, Prevention, and Keynote
Introduction Citrobacter werkmanii is a gram-negative bacterium belonging to the genus Citrobacter. It is commonly found in the environment, including soil, water, and sewage. This bacterium is part of the normal flora of the human intestinal tract but can act as an opportunistic pathogen. C. …
Pantoea agglomerans-Introduction, Morphology, Pathogenicity, Lab Diagnosis, Treatment, Prevention, and Keynote
Introduction Pantoea agglomerans, a Gram-negative, facultative anaerobic bacterium, belongs to the Enterobacteriaceae family. Moreover, it is commonly found in soil, plants, and water. Interestingly, it plays a dual role as a plant symbiont and an opportunistic human pathogen. Additionally, P. agglomerans colonizes plant tissues and …
