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.
A related term is "water-related disease" which is defined as "any significant or widespread adverse effects on human health, such as death, disability, illness or disorders, caused directly or indirectly by the condition, or changes in the quantity or quality of any water".

By contrast, several thousand species are part of the gut flora present in the digestive tract. [citation needed] The body is continually exposed to many species of bacteria, including beneficial commensals, which grow on the skin and mucous membranes, and saprophytes, which grow mainly in the soil and in decaying matter. The blood and tissue ...
In the event of a flood, many residents and emergency personal are exposed to unclean water, which can result in several different types of skin conditions.Flood waters contain pathogens and chemicals from coming in contact with raw sewage, oil, gasoline, and household chemicals such as paints (sometimes lead based) and insecticides.
Most organisms involved in water purification originate from the waste, wastewater or water stream itself or arrive as resting spore of some form from the atmosphere. In a very few cases, mostly associated with constructed wetlands , specific organisms are planted to maximise the efficiency of the process.
Micrococcus is a genus of bacteria in the Micrococcaceae family. Micrococcus occurs in a wide range of environments, including water, dust, and soil. Micrococci have Gram-positive spherical cells ranging from about 0.5 to 3 micrometers in diameter and typically appear in tetrads.
Ingesting food or water contaminated with feces can result in hepatitis A, a liver disease that can resolve on its own — but poor nutrition and sanitation can increase the risk of complications.
Bacterial flora is endogenous bacteria, which is defined as bacteria that naturally reside in a closed system. [6] Disease can occur when microbes included in normal bacteria flora enter a sterile area of the body such as the brain or muscle. [6] This is considered an endogenous infection.
