On the ISS found bacteria that are not afraid of antibiotics

The human body is replete with diversebacteria - you can’t completely get rid of them, even using the most powerful sterilization methods. Consequently, bacteria in any case will live even in the cleanest and most actively protected premises, like the board of the International Space Station. During the next inspection of the ISS, the researchers found that rod-shaped Enterobacter bacteria live on its board, which are not only dangerous to humans, but also resistant to antibiotics.

Microbiologists from the Jet Propulsion LaboratoryNASA regularly samples microbes on board the station. Their goal is to find out how cosmic radiation, increased concentrations of carbon dioxide and weightlessness affect the life and spread of microbes.

During one of the toilet checks andtraining room they found several strains of Enterobacter bugandensis bacteria. They are as similar as possible to a group of microbes recently discovered on Earth. They were the cause of diseases in newborns and people with reduced immunity - the victims were hospitalized in East Africa, Washington and Colorado.

Samples in which bacteria were found werecollected in 2015. Three years have passed since then, and during this time, astronauts did not show any painful symptoms. At the moment, nothing threatens their health, but there is still a small risk. Microbiologists have found that bacteria are resistant to antibiotics, which include penicillin, cefoxitin and oxacillin.

Computer simulations have shown that their risktransformation into a pathogen for the occurrence of diseases in astronauts is 79%. Researchers intend to do more research and develop preventive methods against possible diseases.

Fortunately, in September 2018, researchers fromGenentech has already begun developing antibiotics to cope with even the most resistant viruses. However, it should be borne in mind that creating a full-fledged drug will take a lot of time.
