Skin flora, also called skin microbiota, refers to microbiota (communities of microorganisms) that reside on the skin, typically human skin. Many of them are bacteria of which there are around 1,000 species upon human skin from nineteen phyla. [1] [2] Most are found in the superficial layers of the epidermis and the upper parts of hair follicles.
An alkaline urine sample is a possible sign of P. mirabilis. It can be diagnosed in the lab due to characteristic swarming motility, and inability to metabolize lactose (on a MacConkey agar plate, for example). Also P. mirabilis produces a very distinct fishy odor.
Urinalysis, a portmanteau of the words urine and analysis, [1] is a panel of medical tests that includes physical (macroscopic) examination of the urine, chemical evaluation using urine test strips, and microscopic examination.

Uncontaminated urine samples are difficult to obtain without urinary catheterization due to the proximity of the urinary system to genitals and the GI tract. This is especially a problem for female patients, who are often uninformed about proper clean-catch urine collection procedure or the significance of skin flora in urinary cultures.
It is part of the skin flora of humans, [3] and its largest populations are usually found at the axillae, perineum, and inguinal areas. [4] S. haemolyticus also colonizes primates and domestic animals. [4] It is a well-known opportunistic pathogen, and is the second-most frequently isolated CoNS (S. epidermidis is the first). [5]

Struvite stone formation can be sustained only when ammonia production is increased and the urine pH is elevated to decrease the solubility of phosphate. Both of these requirements can occur only when urine is infected with a urease-producing organism such as Proteus. Urease metabolizes urea into ammonia and carbon dioxide: urea 2 NH 3 + CO 2 ...
