Sequestration of house flies to monitor outbreaks of diseases


In news destined to do the common thing
even more paranoid germophobe about that fly buzzing around the
picnic table, a team of researchers has discovered that the house flies and
Flies blow can spread a large amount of bacteria that previously were not suspected to hook insects. The recently published study also suggests that a fly
the transport capacity of bacteria could be hijacked and used in a public
Sanitary surveillance capacity to track outbreaks of pathogens.

We've known for a long time
The house fly can transmit a series of diseases, but a new study has just
revealed that we could have underestimated the volume and breadth of
bacteria that these annoying insects can transmit. An international
team led by the Nanyang Technological University developed a new way of
collect flies without contaminating them with other microorganisms and then sequencing
DNA from every part of your body. This allowed to identify species of bacteria that they collected in their trips.

"Our study has shown that bacteria
can & # 39; fly & # 39; getting hooked on common flies, "says Stephean
Schuster, a research director who directs the study. "They collect the
microbiome on his feet, he spread them across his wings in a similar
similar to how we would comb our hair, and then proceed to disperse
them on surfaces that land. "

Researchers sequenced genetics
material of 116 species of house fly and blow fly. After separating
all the genetic data that corresponded to the fly's own chromosomes
and symbiotic bacteria, the remaining DNA and RNA were clbadified against
a database of all known bacteria.

The study found terrifyingly that
flies have the ability to transport and propagate hundreds of different
bacteria, some linked to human diseases. A bacterium, for example,
called Helicobacter pylori was found in some flies. This bacterium, which is known to cause
Stomach ulcers and is a major risk factor for gastric cancer, never before had it been shown to be transmitted
for the flies.

Not everything is bad news, with the
the researchers suggested that this discovery could have a positive use.
The study indicates that flies raised in the laboratory could be successfully bred for
be free of germs and released into the environment to act as bacterial surveillance drones. With the ability to enter tiny nooks, flies could be recaptured using bait traps and their microbiome sequenced to reveal the types of bacteria they had encountered on their trips.

"Tales & Autonomous Bionic Drones & # 39;
could be particularly useful in agriculture, if we want to detect a
outbreak of plant pathogens, "says Professor Schuster." Through regular monitoring, if
know that a particular pathogen is affecting crops and is
becoming an outbreak, farmers could organize an objective
treatment that only eradicates that pathogen, leaving the other parts
of the intact ecosystem. "

The study was published in the journal
Scientific reports .
