Flies are usually found on dead bodies of dead or dead animals, and they feed on rotten food. It is not unusual for flies to be regarded as infectious insects of germs.
A study published on November 24 found that this prejudice against Paris is not wrong. Professor Donald Bryant, a biochemist at Pennsylvania State University who led the study, said that "Paris contributes to the rapid spread of pathogens in an outbreak of disease."
The study found that flies and black flies in the house, the most common species in Paris, had 316 species and 316 bacteria, respectively.
In a study titled "Black flies and house flies, low-lying bacteria that act as bacterial transformants," the researchers identified 53 housefly species collected from the United States, Brazil, and Singapore, I analyzed it.
As a result, flies reaffirmed that pathogenic fungi such as bacteria, fungi, and viruses cause infectious diseases. According to the Pennsylvania State University's Department of Agriculture Science, the housefly carries 65 diseases that can infect organs or parts of the body. Diseases that housefly can carry include cholera (affect small intestine), leprosy (mainly skin), polio or infantile paralysis (nerve), tuberculosis (usually lung), and typhoid (digestive organ).
Even so, the Singapore Times said that the flies, like bees, act as pollen mediators and play an important role in nature, according to entomologist Anna Martins. But Dr Zankeira also emphasized that Paris should never come close to people's food or drinks.
