Genes of antibiotic resistance discovered in airplanes and hospitals: study.

According to ТСН: Researchers have found a similar set of microbes, mainly harmless bacteria originating from human skin and the environment, in airplanes and hospitals. They also detected a high level of genes responsible for antibiotic resistance, even in the absence of pathogens that could interact with these antibiotics. This indicates that antibiotic resistance is widespread in nature and can be transmitted even among harmless bacteria.

How air contamination was studied

The study began in January 2022 during the COVID-19 pandemic when people were concerned about air quality in enclosed spaces, especially on airplanes. Initially, scientists planned to collect bacterial samples from HEPA air filters on board, but replacing these filters is an expensive and technologically complicated procedure. Therefore, researchers asked passengers on domestic and international flights to wear masks, which were then sent for analysis in sealed packages. They separately collected masks from medical personnel.

Scientists analyzed samples from the outer surface of the masks that had contact with the air in enclosed spaces and airplanes, not from the inside, where bacteria from participants' airways would accumulate.

Despite people's concerns about pathogens, it turned out that the main source of bacteria in the air is humans themselves. However, scientists emphasize that this does not mean masks can be discarded. They can significantly reduce the risk of contracting diseases transmitted through coughing or sneezing. Researchers also remind not to forget about handwashing, as contact transmission is particularly common in crowded places like airports or hospitals.

It should be noted that scientists have determined that electronic cigarettes (vapes) can contain bacterial and fungal contamination up to 3000 times more than the seat of an average public toilet. Laboratory experiments have shown that the warm and moist environment of the mouthpiece quickly becomes an ideal breeding ground for microorganisms if the device is not cleaned regularly.

These studies underscore the importance of maintaining hygiene measures in public places, especially during epidemics. Masks and regular handwashing remain effective tools for reducing health risks, emphasizing the necessity of a conscious approach to personal hygiene, especially during times of increased illness.
