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.
The formation of urine takes place in microscopic structures called nephrons, about one million of which are found in a normal human kidney. Blood enters the kidney though the renal artery and flows through the kidney's vasculature into the glomerulus , a tangled knot of capillaries surrounded by Bowman's capsule .
In microbiology, the term isolation refers to the separation of a strain from a natural, mixed population of living microbes, as present in the environment, for example in water or soil, or from living beings with skin flora, oral flora or gut flora, in order to identify the microbe(s) of interest.

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 ...
Enterobacter cloacae is a member of the normal gut flora of many humans and is not usually a primary pathogen. [9] Some strains have been associated with urinary tract and respiratory tract infections in immunocompromised individuals.
Colonial morphology serves as the first step in the identification of microbial species from clinical samples. [10] Based on the visual appearance of the colonies, microbiologists can narrow down the list of possible organisms, allowing them to select appropriate tests to provide a definitive diagnosis.
Since that time, many urologists will order a "urine C & S" (urinalysis with bacterial/fungal cultures and testing for sensitivities to anti-infective medications) prior to the performance of the cystoscopy, and as part of the pre-operative workup. Depending on the results of the testing and other circumstances, he or she may elect to prescribe ...
