| By HealthDay News – Many flies and flying insects in hospitals carry bacteria that could pose an infection risk to patients, and more than half of them carry the types that resist antibiotics, a new study says.
British researchers used ultraviolet-light flytraps, electronic fly killers and sticky traps to collect nearly 20,000 flies, aphids, ants, wasps, bees and moths at seven hospitals in England over 18 months, and found that almost 9 in 10 insects had potentially harmful bacteria on or in their bodies.
A total of 86 bacterial strains were found in the insects. Enterobacteriaceae — a family that includes E. coli and Salmonella — were the most common (41 percent), followed by Bacillus (which includes the food poisoning germ B. cereus at 24 percent and staphylococci (which includes S. aureus, a cause of skin infections, abscesses and respiratory infections) at 19 percent …
The study also found that 53 percent of the bacterial strains on the insects were resistant to at least one class of antibiotics — so-called “superbugs.” Of those, 19 percent were resistant to multiple antibiotics.
“What’s quite interesting, though, is the high proportion of drug-resistant bacteria found in these samples. It’s a vivid reminder of how our overuse of antibiotics in health care settings is making infections more difficult to treat,” a researcher said in a university news release … Read more.
