Pathogenic or disease-causing bacteria are microorganisms that can cause various diseases in humans and animals. They can be both harmful to humans and beneficial in some cases. Pathogenic bacteria can cause diseases such as influenza, pneumonia, tuberculosis, cholera, typhoid fever and others.
Pathogenic bacteria usually have the form of cocci or rods. They reproduce by cell division and can survive in a variety of conditions, including low temperatures, high temperatures and the absence of oxygen. Some pathogenic bacteria can also produce toxins that cause symptoms of the disease.
Various methods are used to combat pathogenic bacteria, including antibiotics, vaccines and immunostimulants. However, not all bacterial pathogens are sensitive to antibiotics, so it is important to diagnose and treat at an early stage of the disease.
