The family pet could be a risk factor for infections of multi-resistant bacteria in humans, posits an upcoming study by University of Missouri-Columbia researchers. These infections, which are caused by antibiotic-resistant bacteria such as Methicillin-resistant Staphylococcus aureus (MRSA), was once confined to hospital and post-operative patients. However, rates have been increasing dramatically and impacting other populations, including the military, sports teams, prison populations, and the general public.MRSA rates, for instance, made up just 2 percent of the total staphylococcal infections in 1974. By 1995, it had jumped to 22 percent, and in 2004 to 63 percent.Researchers are now looking for environmental factors that could be contributing to the increase in MRSA bacteria, which live in the noses and on the skin of humans and animals.Though MRSA can exist and not produce symptoms, if the bacteria enter your tissue through a cut or puncture, a serious, sometimes life threatening, infection can occur.The study will examine whether family pets could be acting as “reservoirs” of antibiotic-resistant bacteria, and thusly contributing to the increase of these infections among the general population.
