Water pipe bacteria "flushed out" of the hospital sink.

Biotechnology Channel News: Bacteria as a class of primary nuclear microorganisms, is a kind of small shape, simple structure, multi-splitting mode of reproduction of primary nuclear organisms, is the most widely distributed in nature, the largest number of individuals, is the main participant in the natural material cycle.
bacteria can "flourish" in P-type water bends.
"U-tube" under these sinks collect everything from dropped earrings to lost toothpaste tube lids.
's a big problem, especially in hospitals, where the sinks are full of bacteria.
To determine how the pathogens spread, the researchers built a device that contained rows of five washbasps, all of which, like sinks used in some hospitals, drained sewage into a pipe.
disinfecting all parts of the sink and isolating the operating table with a resin glass shield, the scientists placed harmless fluorescent bacteria in the P-shaped water bend to track their whereing.
More, the researchers added a nutrient liquid culture to it daily to simulate the flow of fluids, such as intravenous fluids and beverage residues, into the hospital's washbasin, resulting in bacteria "thriving" and "climbing" the pipe at a rate of 2.5 cm per day, contaminating the sink's mouth cap.
this way, the water coming down the tap hits the mouth and splashes, which can contaminate the water tank and the operator's station.
the research team recently published the results in Applied and Environmental Microbiology.
In addition, bacteria can contaminate three other sinks in just one week through a common drain, even if there is only one tank of P-type water bends contaminated, even if there is a separate tap and no nutrients.
next step, the researchers will track how bacteria "jump" from the sink to the patient.
