Russian scientists of the ITMO University together with colleagues from the USA investigated the microbiome of the Moscow metro, and identified principal represented there bacteria. The scientific results published in the journal Computational and Structural Biotechnology Journal.
The publication says that the diversity of microbes in public transport is closely linked to the volume of passenger traffic, since most of the microorganisms are brought in the subway on the human skin and the soles of shoes. For the study the samples were collected from floor, walls and handrails. In the laboratory these samples were grown bacteria.
According to the data obtained in the Moscow metro is bacteria of the genus Arsenicicoccus, Brevundimonas, Dietzia, and Pseudomonas, Stenotrophomona. No dangerous pathogens were not detected. The authors noted that the microbial environment of the Moscow subway like new York.
In 2016, American researchers conducted a similar study in the Boston subway and came to the conclusion that, contrary to popular belief, the underground of large cities cannot be called a hotbed of dangerous germs. Having studied samples from the seats, handrails and apparatus ticket, the scientists found that on these surfaces the germs not more than in other places in the city. Most of the microorganisms was detected on the rail, most commonly seen skin bacteria Propionibacterium acnes, which causes acne.
