How long can bacteria in feces survive in the air?

We usually need to clean up the feces in time after defecation. If it is not cleaned and exposed to the air for a long time, bacteria will fly in the air and often survive for more than a few months. Inhalation into the human body will cause many complications, so we must disinfect our bathroom supplies in time.

Can bacteria and viruses survive in the air for a long time?

Viruses and bacteria can survive in the air

Most viruses die within a short period of time after leaving the human body, but the SARS virus can survive in the air for about 10 minutes. However, bacterial spores can survive for a long time (they can only be inactivated by boiling at 100'C for more than 3 hours). When working in an Internet cafe, I think what I am most worried about is not the bacteria on the keyboard and mouse, as these bacteria are transmitted by contact. Generally, the three lines of defense of the human skin will not be penetrated. Wash your hands frequently with soap, especially before eating, so as not to be infected with any serious disease. There are many different types of people in Internet cafes, with high mobility. Some Internet cafes are not well ventilated, and there are many bacteria and viruses transmitted through the respiratory tract. Environmental disinfection should be strengthened

Uses and hazards

Bacteria can be both useful and harmful to the environment, humans and animals. Some bacteria become pathogens, causing tetanus, typhoid, pneumonia, syphilis, cholera and tuberculosis. In plants, the bacteria causes leaf spot, fire blight, and wilt. Modes of infection include contact, airborne transmission, food, water and carriers of bacteria. Pathogens can be treated with antibiotics, which are divided into bactericidal and bacteriostatic types.

Bacteria are often used together with yeast and other types of fungi to ferment foods. For example, in the traditional production process of vinegar, acetic acid bacteria (Acetobacter) in the air are used to convert wine into vinegar. Other foods made using bacteria include cheese, kimchi, soy sauce, vinegar, wine, yogurt, etc. Bacteria can also secrete a variety of antibiotics, for example, streptomycin is secreted by Steptomyces.

The ability of bacteria to degrade a wide range of organic compounds is also often used to clean up pollution, known as bioremediation. For example, scientists used methanotrophs to break down trichloroethylene and tetrachloroethylene pollution in Georgia, USA.

Bacteria also have a great impact on human activities. For example, the production of cheese and yogurt, the manufacture of some antibiotics, and the treatment of wastewater are all related to bacteria. In the field of biotechnology, bacteria are also widely used.
