We always see the name of bacteria multiplying in many places. Bacteria are mainly caused by imbalance in the body and will multiply in large numbers in our body. Therefore, bacteria are sensitive and very small. They are invisible and intangible, and not easy to diagnose. Maintaining a good balance of bacteria at ordinary times is a very important step. The details are as follows: 1. Introduction Bacteria in a broad sense are prokaryotes. It refers to a large class of primitive single-celled organisms whose cell nucleus is not surrounded by a nuclear membrane and only has naked DNA in a region called the nuclear region (or nucleus). It includes two major groups: eubacteria and archaea. What people usually refer to are bacteria in a narrow sense. Bacteria in a narrow sense are a type of prokaryotic microorganisms. They are a type of prokaryotes that are short and thin in shape, simple in structure, and mostly reproduce by binary fission. They are the most widely distributed and most numerous organisms in nature, and are the main participants in the material cycle of nature. 2. Basic Information Bacteria (English: germs; scientific name: bacteria) in a broad sense are prokaryotes, which refer to a large class of primitive single-celled organisms whose cell nucleus is not wrapped by a nuclear membrane and only has naked DNA in a region called the nuclear region (or nucleus).

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. |
