Scientific Reports magazine introduced its readers to
the results of a new study on the microbiome of flies.
The Pennsylvania team took up the study of these insects.

Among the microbes, even Helicobacter pylori – a key link
in the development of gastric ulcer and duodenal ulcer.
Of course, people previously knew about the harmfulness of room and
meat flies. But before our time, not a single large-scale
research that actually reflects specific pathogens on the body of flies.
Recall that these insects live extremely “unscrupulous”: polluting
small larvae are feces and already decaying substances, they
become carriers of a mass of harmful bacteria. With
the spread of infection such bacteria can cause massive
outbreaks of infectious diseases and even epidemics.
American experts analyzed the state of the genome
about 120 meat and house flies, which were picked from three
continents. The purpose of the work was to accurately identify microorganisms
present on the body of insects. It turned out that some
flies were hundreds of microbes. Most pathogens
located on the wings and legs.
The genetic information of indoor and meat flies is the same.

a certain range, and then again to catch, you can find out what

The findings of the University of Pennsylvania scientists have not only enriched
human knowledge about the mechanisms of infection by some
pathogenic microbes, but also gave rise to reflection on
use of flies for the benefit of the population. Experts recommend

people is around. After all, people throw out a lot of waste,
being an excellent breeding ground for bacteria and flies. Also
for the first time, scientists found out that these insects are spreading
