The results show that “a large number of flying insects collected in British hospitals contain pathogenic bacteria of various species,” says Federica Boyoquey, director of research and graduate student at the Aston University in Birmingham. British researchers have used ultraviolet, electronic and glue traps for 18 months to collect about 20,000 flies, aphids, ants, axes, bees and butterflies in seven hospitals in England and found that almost 9 out of 10 insects had potentially dangerous bacteria in their bodies. The study also found that 53 per cent of bacterial insect strains were resistant to at least one class of antibiotic called “super mites”. “Of these, 19% were resistant to various antibiotics. Insects were collected in several wings of the hospital, including those that prepared or stored food for patients, visitors and staff, as well as in health facilities, neonatal services and maternity hospitals. Resistance was more prevalent in patients using penicillin, but resistance to other common antibiotics such as vancomycin and levofloxacin was also observed in the study. This is an amazing reminder of how overuse of antibiotics in health care makes it difficult to treat infections,” says a statement to the scientific press. In some cases, the bacterial level of insects was sufficient to cause infection in humans. A total of 86 strains of bacteria have been found in insects. Most of the insects were collected in spring and summer. “However, a large proportion of resistant bacteria in these samples is interesting.
