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]
Bacteriuria is assumed if a single bacterial species is isolated in a concentration greater than 100,000 colony forming units per millilitre of urine in clean-catch midstream urine specimens. [16] In urine samples obtained from women, there is a risk for bacterial contamination from the vaginal flora.
A throat culture is a laboratory diagnostic test that evaluates for the presence of a bacterial or fungal infection in the throat. A sample from the throat is collected by swabbing the throat and placing the sample into a special cup that allows infections to grow. If an organism grows, the culture is positive and the presence of an infection ...
A sputum culture is a test to detect and identify bacteria [1] or fungi that infect the lungs or breathing passages. Sputum is a thick fluid produced in the lungs and in the adjacent airways. Normally, fresh morning sample is preferred for the bacteriological examination of sputum. [ 2 ]
A. haemolyticum is the cause of pharyngitis (sore throat) in up to 2.5% of cases. [8] In one study, it was the causative agent of pharyngitis in 1.4% of military conscripts. [9] It is rarely found in the skin or throat of healthy people, meaning it is not a member of the usual bacterial flora. [3]
Unlike most bacterial pathogens, S. pyogenes only infects humans. Thus, zoonotic transmission from an animal (or animal products) to a human is rare. [8] S. pyogenes typically colonizes the throat, genital mucosa, rectum, and skin. Of healthy adults, 1% to 5% have throat, vaginal, or rectal carriage, with children being more common carriers.
The interpretation of urinalysis takes into account the results of physical, chemical and microscopic examination and the person's overall condition. Urine test results should always be interpreted using the reference range provided by the laboratory that performed the test, or using information provided by the test strip/device manufacturer. [136]
These bacteria are facultative anaerobes, and made up of non-motile and non-sporing cocci (round cells) that are catalase negative. It is a commensal and commonly inhabits the human mouth, throat, and upper respiratory tract, as part of the oral microbiota .
