Mycobacterium ulcerans is a species of bacteria found in various aquatic environments. The bacteria can infect humans and some other animals, causing persistent open wounds called Buruli ulcer . M. ulcerans is closely related to Mycobacterium marinum , from which it evolved around one million years ago, and more distantly to the mycobacteria ...
Berkley Moynihan suggests that acid is a cause of ulcers. [1] 1910 Schwartz publishes the excess acid theory of the ulcer, coining the famous phrase "no acid, no ulcer." [2] Gibelli claims to be unable to reproduce Turck's study where he artificially created ulcers by feeding dogs bacteria. [1] Streptococci 1913

A salt water gargle can even help clear debris, reduce bacteria in your throat and promote healing, Kyriazidis adds. But, she points out, it only provides temporary relief. It can ease irritation ...
Bacterial strains with the cagA gene are associated with the ability to cause ulcers, MALT lymphomas, and gastric cancer. [108] [109] The cagA gene codes for a relatively long (1186-amino acid) protein. The cag pathogenicity island (PAI) has about 30 genes, part of which code for a complex type IV secretion system (T4SS or TFSS).
Pharyngitis is a type of upper respiratory tract infection. [7] Most cases are caused by a viral infection. [2] Strep throat, a bacterial infection, is the cause in about 25% of children and 10% of adults. [2] Uncommon causes include other bacteria such as gonococcus, fungi, irritants such as smoke, allergies, and gastroesophageal reflux disease.
Staphylococcal enteritis is an inflammation that is usually caused by eating or drinking substances contaminated with staph enterotoxin. The toxin, not the bacterium, settles in the small intestine and causes inflammation and swelling. This in turn can cause abdominal pain, cramping, dehydration, diarrhea and fever. [1]
A very common and dangerous type of skin ulcer is caused by what are called pressure-sensitive sores, more commonly called bed sores, which are frequent in people who are bedridden or who use wheelchairs for long periods. [citation needed] Other causes producing skin ulcers include bacterial and viral infections, fungal infections [6] and cancers.
