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]
The HACEK organisms (Haemophilus, Actinobacillus actinomycetemcomitans, Cardiobacterium hominis, Eikenella corrodens, Kingella) are part of the normal oropharyngeal flora, which grow slowly, prefer a carbon dioxide-enriched atmosphere, and share an enhanced capacity to produce endocardial infections, especially in young children.

A normal throat. Pharyngitis is a type of inflammation caused by an upper respiratory tract infection. It may be classified as acute or chronic. Acute pharyngitis may be catarrhal, purulent, or ulcerative, depending on the causative agent and the immune capacity of the affected individual. Chronic pharyngitis may be catarrhal, hypertrophic, or ...
C. valvarum is also differentiated by the fact that the species does not produce indole. [ 1 ] Isolates of C. valvarum show optimal growth by day 3 under standard 5% CO 2 incubation conditions on 5% sheep blood, but scant growth on chocolate agar.
The environment present in the human mouth allows the growth of characteristic microorganisms found there. It provides a source of water and nutrients, as well as a moderate temperature. [ 2 ] Resident microbes of the mouth adhere to the teeth and gums to resist mechanical flushing from the mouth to stomach where acid-sensitive microbes are ...
Bacteria that are members of the 'normal flora' of the region of the infection are often also isolated from lesions involving anaerobic bacteria. [ citation needed ] Specimens obtained from wounds and subcutaneous tissue infections and abscesses in the rectal area (perirectal abscess, decubitus ulcer) or that are of gut flora origin(i.e ...
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 ...
The infection can occur in the respiratory or urinary tracts, as it is a part of the normal flora in those two areas, and will develop into sepsis or septic arthritis. [7] Most K. kingae are sensitive to beta-lactam antibiotics, but reports describe strains producing beta-lactamases. [ 8 ]
