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]
They convert glucose to lactic acid and this acidic environment kills harmful pathogens. The vaginal microbiota in pregnancy varies markedly during the entire time of gestation. The species and diversity of the microorganisms may be related to the various levels of hormones during pregnancy. Vaginal flora can be transmitted to babies during birth.
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 .
Coliform bacteria are defined as either motile or non-motile Gram-negative non-spore forming bacilli that possess β-galactosidase to produce acids and gases under their optimal growth temperature of 35–37 °C. [1] They can be aerobes or facultative aerobes, and are a commonly used indicator of low sanitary quality of foods, milk, and water. [2]
Capnocytophaga spp. can be resistant to third-generation cephalosporins, but remain susceptible to imipenem, cefoxitin, and amoxicillin combined with clavulanic acid. [11] Although resistant strains are most frequently isolated in oral cavities, their prevalence is worrying, (Jolivet-Gougeon et al., 2008; Sixou et al., 2006).
Graphic depicting the human skin microbiota, with relative prevalences of various classes of bacteria. The human microbiome is the aggregate of all microbiota that reside on or within human tissues and biofluids along with the corresponding anatomical sites in which they reside, [1] [2] including the gastrointestinal tract, skin, mammary glands, seminal fluid, uterus, ovarian follicles, lung ...
A. rubiinfantis was discovered from a stool sample taken from an infant with severe acute malnutrition in Senegal. [17] Based on a genomic analysis, Anaerococcus rubiinfantis has high antibiotic susceptibility. [17] For that reason this bacteria can be treated with common oral antibiotics. [17]
S. constellatus are gram positive, non-sporing, non-motile, catalase negative cocci. The cells are small, normally 0.5-1μm in diameter and form short chains. Their cell wall peptidoglycan is composed of Lys-Ala 1-3 and has a DNA G+C content of 37-38%. [5]
