Similarly one may ask, what are some harmful effects of bacteria?
Harmful bacteria are called pathogenic bacteria because they cause disease and illnesses like strep throat, staph infections, cholera, tuberculosis, and food poisoning.
Also, how does infection leave the body? Infection occurs when viruses, bacteria, or other microbes enter your body and begin to multiply. In response to infection, your immune system springs into action. White blood cells, antibodies, and other mechanisms go to work to rid your body of the foreign invader.
Also, how do bacteria make you sick?
Some bacteria help to digest food, destroy disease-causing cells, and give the body needed vitamins. But infectious bacteria can make you ill. They reproduce quickly in your body. Many give off chemicals called toxins, which can damage tissue and make you sick.
Are all bacteria harmful?
Not all bacteria are harmful, and some bacteria that live in your body are helpful. Many disease-causing bacteria produce toxins — powerful chemicals that damage cells and make you ill. Other bacteria can directly invade and damage tissues.
