A Gram-negative, aerobic, non-fermenting coccobacillus and a member of the ESKAPE group of priority pathogens (Enterococcus, Staphylococcus, Klebsiella, Acinetobacter, Pseudomonas, Enterobacter). Acinetobacter baumannii is among the most problematic nosocomial pathogens…
WHO Priority 1: Critical. A Gram-negative, strictly aerobic coccobacillus and one of the most dangerous nosocomial pathogens on the planet. A. baumannii belongs to the ESKAPE group and causes ventilator-associated pneumonia, wound infections, and bloodstream infections …
Campylobacter is a genus of Gram-negative, microaerophilic, spiral-shaped bacteria. C. jejuni is the most common bacterial cause of foodborne gastroenteritis worldwide and a trigger for post-infectious Guillain-Barré syndrome (molecular mimicry between Campylobacter LOS…
Clostridioides difficile is the current NCBI name for NCBITaxon:1496 and the correct, medically recommended combination recorded by LPSN. Both records retain Clostridium difficile as a validly published homotypic synonym of the same organism rather than a separate speci…
Enterobacter cloacae is a Gram-negative, facultatively anaerobic member of the Enterobacteriaceae. Ubiquitous in soil, water, and the mammalian gut, it is a leading cause of nosocomial infections and carries clinically significant antibiotic resistance through inducible…
A family of Gram-negative, facultative anaerobic Gammaproteobacteria that includes many of the most important human pathogens: escherichia coli, klebsiella pneumoniae, salmonella typhimurium, shigella flexneri, yersinia pestis, proteus mirabilis, Morganella, and Serrati…
A genus of Gram-positive bacteria (primarily E. faecalis and E. faecium) that exemplifies the metal-antibiotic resistance co-selection crisis. Enterococci carry diverse metal tolerance genes for mercury, arsenic, copper, and cadmium on the same mobile genetic elements a…
Enterococcus faecium is a Gram-positive, facultatively anaerobic bacterium that epitomizes the metal-antibiotic co selection problem in modern medicine. As one of the six ESKAPE pathogens (the group responsible for the majority of hospital-acquired infections that fail …
A Gram-negative opportunistic pathogen and member of the ESKAPE group of antibiotic-resistant priority pathogens. K. pneumoniae deploys multiple nickel-dependent enzymes for virulence and relies on the dual-function metallophore yersiniabactin for both iron and nickel s…
Lactobacillus rhamnosus is a Gram-positive, facultatively anaerobic lactic acid bacterium and one of the most extensively studied probiotic species. The GG strain (ATCC 53103), isolated from a healthy human intestinal tract by Gorbach and Goldin in 1983, is the single m…
Mycoplasma is a genus of wall-less bacteria in the class Mollicutes, characterized by the smallest genomes of any self-replicating organisms (~580–1,350 kb). The lack of a cell wall makes them intrinsically resistant to beta-lactam antibiotics and undetectable by Gram s…
Ruminococcus albus is a Gram-positive, obligate anaerobic bacterium that represents one of the primary cellulolytic (fiber-degrading) specialists in the human gut microbiota. This species constructs cellulosomes — extraordinary multi-enzyme complexes organized on bacter…
Salmonella is a genus of Gram-negative, facultatively anaerobic bacteria in the family Enterobacteriaceae. The two species — S. enterica (with 2,500 serovars including Typhimurium and Typhi) and S. bongori — cause a spectrum of disease from self-limiting gastroenteritis…
Shigella is a genus of Gram-negative, facultatively anaerobic bacteria in the family Enterobacteriaceae, closely related to Escherichia coli — so closely that many 16S rRNA-based studies report them as the Escherichia/Shigella complex, unable to distinguish the two gene…
A versatile Gram-positive pathogen with one of the best-characterized nutritional immunity evasion systems known. S. aureus requires nickel, iron, zinc, and manganese for virulence and has evolved dedicated acquisition systems for each, including the novel metallophore …
