Risk of toothbrushes in communal bathrooms

Data confirms that there is transmission of fecal coliforms in communal bathrooms at Quinnipiac University and that toothbrushes can serve as a vector for transmission of potentially pathogenic organisms. This research is presented at the annual meeting of the American Society for Microbiology.

"The main concern is not with the presence of your own fecal matter on your toothbrush, but rather when a toothbrush is contaminated with fecal matter from someone else, which contains bacteria, viruses or parasites that are not part of your normal flora," said Lauren Aber, MHS (Graduate Student, Quinnipiac University). Potential microorganisms that can be introduced are enteric bacteria and pseudomonads. Enteric bacteria are a family of bacteria, Enterobacteriaceae, they are known to be normal flora found in the gut. They are also known to ferment glucose, fail to contain cytochrome in an oxidase test and many can reduce nitrates to nitrites. Pseudomonas group of bacteria are gram-negative aerobic rods commonly found in soil, water, plants and animals. They are part of the normal flora of the gut and also on the skin of humans.
