Skin flora is usually non-pathogenic, and either commensal (are not harmful to their host) or mutualistic (offer a benefit). The benefits bacteria can offer include preventing transient pathogenic organisms from colonizing the skin surface, either by competing for nutrients, secreting chemicals against them, or stimulating the skin's immune ...
Other bacteria often found in recreational waters are Enterococci, [5] which is a genus of bacteria found in feces. Fecal contamination is one of the primary public health concerns in swimming pools. [4] Fecal contamination usually occurs through excretion by bathers, other animals, or contaminated water sources. [4]
Bacteria can enter an open wound from contaminated water sources. Can enter the gastrointestinal tract through consumption of contaminated drinking water or (more commonly) food Dry mouth, blurred and/or double vision, difficulty swallowing, muscle weakness, difficulty breathing, slurred speech, vomiting and sometimes diarrhea.
People who swim in fecal bacteria-contaminated water are at risk of gastroenteritis, which causes vomiting, nausea, stomach cramping, diarrhea and other symptoms, according to the U.S ...
Tap water contains chlorine and other minerals that can hurt your skin.
Each cycle works together to regulate the microorganisms in certain processes. [33] For example, the nitrogen gas which makes up 78% of the Earth's atmosphere is unavailable to most organisms, until it is converted to a biologically available form by the microbial process of nitrogen fixation .

Cutibacterium acnes bacteria predominantly live deep within follicles and pores, although they are also found on the surface of healthy skin. [3] In these follicles, C. acnes bacteria use sebum, cellular debris and metabolic byproducts from the surrounding skin tissue as their primary sources of energy and nutrients.
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]
