where does the bacteria that causes gonorrhea come from
Gonorrhea Gonorrhea is spread through sexual contact with an infected person.[1] This includes oral, anal, and vaginal sex.[1] It can also spread from a mother to a child during birth.[1] Diagnosis is by testing the urine, urethra in males, or cervix in females.[1] Testing all women who are sexually active and less than 25 years of age each year as well as those with new sexual partners is recommended;[3] the same recommendation applies in men who have sex with men (MSM).[3]
Helicobacter pylori Helicobacter pylori, previously known as Campylobacter pylori, is a Gram-negative, microaerophilic bacterium usually found in the stomach. It was identified in 1982 by Australian scientists Barry Marshall and Robin Warren, who found that it was present in a person with chronic gastritis and gastric ulcers, conditions not previously believed to have a microbial cause.[7][8][9] It is also linked to the development of duodenal ulcers and stomach cancer. However, over 80% of individuals infected with the bacterium are asymptomatic, and it may play an important role in the natural stomach ecology.[10]
