Enterobacteriaceae is a large family of Gram-negative bacteria. It includes over 30 genera and more than 100 species. It includes over 30 genera and more than 100 species. Its classification above the level of family is still a subject of debate, but one classification places it in the order Enterobacterales of the class Gammaproteobacteria in ...
Bacilli usually have a rod or cylinder shape. Examples include Listeria, Salmonella typhimurium, Yersinia enterocolitica, and Escherichia coli.

These early findings may be followed by signs and symptoms of shock. [ citation needed ] Biliary tract infection is usually caused by E. coli, Klebsiella and Enterococcus spp. Anaerobes (mostly B. fragilis group, and rarely C. perfringens ) can be recovered in complicated infections associated with carcinoma, recurrent infection, obstruction ...
[26] [44] Several studies have demonstrated that a significant proportion (7–33%) of healthy asymptomatic women (especially black and Hispanic women) [45] lack appreciable numbers of Lactobacillus species in the vagina, [33] [46] and instead have a vaginal microbiota that consist of other lactic acid-producing bacteria, i.e. species from the ...
Escherichia (/ ˌ ɛ ʃ ə ˈ r ɪ k i ə / ESH-ə-RIK-ee-ə) is a genus of Gram-negative, non-spore-forming, facultatively anaerobic, rod-shaped bacteria from the family Enterobacteriaceae. [3] In those species which are inhabitants of the gastrointestinal tracts of warm-blooded animals, Escherichia species provide a portion of the microbially ...
This is the list of organisms that are found in the lower reproductive tract of sexually mature women who are not immunocompromised. A partial description of pathogens that can be found in the lower and upper reproductive tract of women can be found in the article sexually transmitted infection .
This is the list of organisms that are found in the vagina that are associated with bacterial vaginosis, an infectious disease of the vagina caused by excessive growth of specific bacteria. [ 4 ] [ 5 ] The census and relationships among the microbiota are altered in BV, resulting in a complex bacterial milieu.
Prevotella species may be commensal in the vagina, though increased abundance of Prevotella in vaginal mucosa is associated with bacterial vaginosis.A study of 542 Korean women, including identical and fraternal twins, highlighted that the vaginal microbiota's composition is influenced by menopausal status and bacterial vaginosis, with Lactobacillus and Prevotella being the most inheritable ...
