Fusobacterium is a genus of obligate anaerobic, Gram-negative, [2] non-sporeforming bacteria [3] belonging to Gracilicutes. Individual cells are slender, rod-shaped bacilli with pointed ends. [ 4 ] [ 5 ] Fusobacterium was discovered in 1900 by Courmont and Cade and is common in the flora of humans.
Rothia mucilaginosa is a Gram-positive, coagulase-negative, encapsulated, non-spore-forming and non-motile coccus, present in clusters, tetrads or pairs that is a part of the normal oropharyngeal flora. [3] Belonging to the family Micrococcaceae, it was first isolated from the mucous membrane of the cheek and gingiva. [4]
Pluralibacter gergoviae has been isolated from maize, grapes, coffee beans, spring water, fruit flies, and pink bollworms. [4] It is an uncommon human pathogen, most commonly as an opportunistic nosocomial infection. One hospital in Spain reported the organism to represent 0.4% of clinical Enterobacter isolates. Risk factors include prolonged ...
Streptococcus constellatus is a species of Streptococcus [2] bacteria that is part of the normal flora in the oral cavity, urogenital region, and intestinal tract. However, it can frequently cause purulent infections in other parts of the body. [3]
Klebsiella aerogenes, [2] previously known as Enterobacter aerogenes, is a Gram-negative, oxidase-negative, catalase-positive, citrate-positive, indole-negative, rod-shaped bacterium. [3]
It has a commensal relationship within the intestinal tracts of humans, mammals, and reptiles as normal flora. [2] Although M. morganii has a wide distribution, it is considered an uncommon cause of community-acquired infection, and it is most often encountered in postoperative and other nosocomial infections , such as urinary tract infections .
F. necrophorum infection (also called F-throat [12]) usually responds to treatment with augmentin or metronidazole, but penicillin treatment for persistent pharyngitis appears anecdotally to have a higher relapse rate, although the reasons are unclear. [citation needed]
Streptococcus salivarius is a species of spherical, gram-positive, facultative anaerobic lactic acid bacteria [1] that is both catalase and oxidase negative. S. salivarius colonizes (usually in chains) the oral cavity and upper respiratory tract of humans just a few hours after birth, making further exposure to the bacteria harmless in most circumstances.
