Trichosporon species: Introduction, Morphology, Medically Important Species, Pathogenicity, Lab Diagnosis, Treatment, Prevention, and Keynotes
Introduction Trichosporon is a genus of anamorphic, yeast-like basidiomycetous fungi widely distributed in nature, particularly in tropical and temperate regions. First identified by Beigel in 1865, it commonly exists as a saprophytic organism in soil, water, plants, and animal droppings. In humans, it is a normal commensal of the skin, respiratory tract, oral cavity, and gastrointestinal tract. Historically, clinical isolates were grouped under the umbrella term Trichosporon beigelii (or T. cutaneum). Modern molecular taxonomy has split the...
Acinetobacter baumannii complex-Introduction, Species in this group, Morphology, Pathogenicity, Lab Diagnosis, Treatment, Prevention, and Keynotes
Introduction The Acinetobacter baumannii complex (ABC) is a group of highly resilient, opportunistic Gram-negative bacteria that pose a critical threat in healthcare settings. Classified as an "ESKAPE" pathogen, it is a leading cause of severe hospital-acquired (nosocomial) infections. The World Health Organization (WHO) categorizes carbapenem-resistant Acinetobacter baumannii (CRAB) in the highest "critical priority" tier for the development of new antibiotics. Species in this Group Because these species are genetically distinct but phenotypically almost identical, standard diagnostic...
Sphingomonas paucimobilis-Introduction, Morphology, Pathogenicity, Lab Diagnosis, Treatment, Prevention, and Keynote
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 is capable of surviving in nutrient-poor conditions and forming robust biofilms inside hospital water networks, medical equipment, and dialysis solutions. Morphology and Characteristics Cell Morphology Gram Stain: Gram-negative straight or slightly curved rod cells. Size: Small, measuring approximately...
