Flies responsible for Bacterial Invasions
“Flies can contribute to the rapid transmission of pathogens during outbreaks” reveals study.
Nature is full of beings full of ambition, small and great conquerors who want to expand their domains and those of their species.
Humans can seem like a successful group, but nothing if compared to bacteria.
These microorganisms have an amazing ability to adapt and, although they have not been able to build aircraft with which to expand across the planet, they have found numerous allies to supply their engineering deficiencies.
Last week, an international team of scientists conducted a study that attempted to understand the role of flies in the transmission of bacterial diseases.
In an article published in the Journal Scientific Reports, they explain that they studied the microbiomes of 116 flies from three different continents.
Flies as Bacteria Airways
As they explain in a statement, in some cases these flies were true bacteria carriers, carrying hundreds of different species, many of which are capable of making people sick.
The authors of the work, led by Donald Bryant, Penn State University (USA), analyzed the microbes housed in different parts of the bodies of insects.
:This allowed us to observe that the legs are the appendages through which most of the microbes are transmitted when they are collected on one surface and deposited in another,” aid Bryant.
“The legs and wings show the highest microbial diversity in the body of the fly, which suggests that bacteria use flies as ferries,” says Stephan Schuster, director of Nanyang University of Technology in Singapore.
Study got interesting results
On the one hand, although flies have a preference for unhygienic environments where they find decomposing organic matter and faeces that serve as food for their young, with the greatest bacterial diversity on board these insects were not found on farms but in urban environments.
The researchers found, in several flies collected in Brazil, the bacterium Helicobacter pylori, frequent cause of ulcers.
According to Schuster, the flies were not considered until now a possible transmitter of these diseases.
Bryant believes that his study points to a mechanism for the transmission of pathogens “that could have been overlooked by those responsible for public health” and that “flies can contribute to the rapid transmission of pathogens during outbreaks.”
In addition, those responsible for the article believe that this system to analyze the DNA of microbes that transport insects can turn these small animals into messengers for the collection of samples in inaccessible places and even in early warning systems against epidemics.
