Scientists at the University of Buffalo found: pathogenic microorganisms can survive for a long time in the environment, surviving cleaning around the house and various chemicals. In a certain state, they can exist for a long time. The most frequent case was found among pathogenic bacteria - Streptococcus pneumoniae and Streptococcus pyogenes, says Medical News Today. Data infectious agents can survive in the environment for a long time.
It should be noted that previously it was thought that the data Bactria quickly die in the external environment. S. Pyogenes is the source of infection of the respiratory tract. S. pneymonia is the main causative agent of pneumonia. In addition, bacteria are capable of spread through the body and cause inflammation of the organ of hearing. At the moment it is known that bacteria can form biofilms, providing self-protection from the immune system. This increases their survival in the internal environment.
During the research it was found the presence of pathogenic bacteria in the pillow in 80% of cases, given that each pillow was subjected to a preliminary treatment, and the last human contact occurred after a large amount of time.
Scientists believe that some dangerous bacteria are able to multiply even in extreme conditions and to form biofilms on the surface of everyday items. Thus there is a separation of infection.
