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. [5]
The predominant organisms are of oropharyngeal flora origin and include AGNB, Fusobacterium [17] and Peptostreptococcus spp. Anaerobes involve almost all dental infections. These include dental abscesses, [18] endodontal pulpitis and periodontal (gingivitis and periodontitis) infections, and perimandibular space infection.
All of these organisms are part of the normal oropharyngeal flora, which grow slowly (up to 14 days), prefer a carbon dioxide–enriched atmosphere, and share an enhanced capacity to produce endocardial infections, especially in young children.
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 ...
Members of the HACEK group are difficult to identify through conventional methods. 16S ribosomal RNA genotyping is the necessary method of identifying C.valvarum [2].C.valvarum bears numerous phenotypic similarities with Pasteurella multocida and is therefore commonly misidentified.
The microbiome present in seminal fluid has been evaluated. Using traditional culturing techniques the microbiome differs between men who have acute prostatitis and those who have chronic prostatitis. Identification of the seminal fluid microbiome has become one of the diagnostic tools used in treating infertility in men that do not display ...
Kingella kingae is a species of Gram-negative facultative anaerobic β-hemolytic coccobacilli. First isolated in 1960 by Elizabeth O. King, it was not recognized as a significant cause of infection in young children until the 1990s, when culture techniques had improved enough for it to be recognized.
