Then in 1883, Max Bockhart proved conclusively that the bacterium isolated by Albert Neisser was the causative agent of the disease known as gonorrhea by inoculating the penis of a healthy man with the bacteria. The man developed the classic symptoms of gonorrhea days after, satisfying the last of Kochs postulates. Until this point, researchers debated whether syphilis and gonorrhea were manifestations of the same disease or two distinct entities. One such 18th-century researcher, John Hunter, tried to settle the debate in 1767 by inoculating a man with pus taken from a patient with gonorrhea. He erroneously concluded that both syphilis and gonorrhea were indeed the same disease when the man developed the copper-colored rash that is classic for syphilis. Although many sources repeat that Hunter inoculated himself, others have argued that it was in fact another man. After Hunters experiment other scientists sought to disprove his conclusions by inoculating other male physicians, medical students, and incarcerated men with gonorrheal pus, who all developed the burning and discharge of gonorrhea. One researcher, Ricord, took the initiative to perform 667 inoculations of gonorrheal pus on patients of a mental hospital, with zero cases of syphilis. Notably, the advent of penicillin in the 1940s made effective treatments for gonorrhea available. See also

Bednars aphthae is a type of oral ulceration (mouth ulcers) which occurs in infants. The lesions are located on the palate and are caused by trauma. No treatment is required since the lesions heal within a few days.The condition was first described in 1850, by the Austrian physician Alois Bednar (1816-1888). References
