Following are the harmful bacteria with the diseases they cause:

1) Clostridium tetani, C. perferengies and C. difficile

Disease: C. tetani is the etiologic agent of tetanus. It enters the body through a wound, replicates there and releases toxins, namely tetanospasmin (aka, spasmogenic toxin) and tetanolysin. These lead to muscular spasms and respiratory failure.
Clostridium perfringens causes gas gangrene or tissue death.
Clostridium difficile can cause antibiotic-induced diarrhea. According to the U.S. National Library of Medicine, Clostridium is associated with gas gangrene and colitis caused by antibiotics.

2)Yersinia pestis

Disease: Y. pestis causes bubonic and pneumonic plague. A skin infection with Y. pestis leads to the bubonic form characterized by malaise, fever, chills, and even seizures. An infection in the lungs caused by Y. pestis leads to pneumonic plague causing coughs, difficulty in breathing, and fever. According to WHO, around 1000 to 3000 cases of plague are reported worldwide every year. This microbe is being recognized and explored as a potential bioweapon.

3)Helicobacter pylori

Disease: It is the leading cause for gastritis and peptic ulcers. It produces cytotoxins and ammonia which damage the stomach epithelium leading to abdominal pain, nausea, vomiting, and bloating. H. pylori is present in half of the world's population, however, most of them are asymptomatic while only a few develop gastritis and ulcers.

4)Bacillus anthracis

Disease: The deadly disease called anthrax is a result of a B. anthracis infection, where the inhalation of B. anthracis endospores is what causes this illness. Anthrax mainly occurs in sheep, goats, cattle, etc. However, the transmission of bacteria from domestic cattle to humans, occurs in rare cases. The formation of sores, fever, headache, abdominal pain, nausea, diarrhea etc., are the most common symptoms (of anthrax).

5)Mycobacteria

Disease: The bacteria under the genus Mycobacterium are pathogens with long doubling times. M. tuberculosis and M. leprae, the most notorious species, are the causative agents for tuberculosis and leprosy, respectively. M. ulcerans causes ulcerated and non-ulcerated nodules in the skin. M. bovis causes tuberculosis in cattle.
