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. [9] The man developed the classic symptoms of gonorrhea days after, satisfying the last of Koch's postulates. Until this point ...
Genetic transformation is the process by which a recipient bacterial cell takes up DNA from a neighboring cell and integrates this DNA into the recipient’s genome by recombination. In N. meningitidis and N. gonorrhoeae , DNA transformation requires the presence of short DNA sequences (9-10 monomers residing in coding regions) of the donor DNA.
Vaginal cytology is a microscopic examination of cells from the vaginal epithelium.In veterinary medicine, it helps differentiate the stages of the mammalian estrous cycle because the vaginal epithelium changes in response to sex hormone levels; practically, it is used to distinguish when a female canine is at a particular point in the estrous cycle.

Gonorrhoea or gonorrhea, colloquially known as the clap, [7] is a sexually transmitted infection (STI) caused by the bacterium Neisseria gonorrhoeae. [8] Infection may involve the genitals, mouth, or rectum. [9] Gonorrhea is spread through sexual contact with an infected person, [1] or from a mother to a child during birth. [1]
Neisseria cinerea can produce acid from glucose like N. gonorrhoeae, but it will then oxidize the acid to carbon dioxide. [2] Although it can break down glucose, it is unable to use glucose or other carbohydrates for energy, making it asaccharolytic. [1]
Super-gonorrhea sounds scary. How concerned should people in the U.S. be? Antibiotic-resistant gonorrhea is rare in the U.S., but El Sahly says it’s still important to take it seriously.
Although infections like chlamydia, for example, are highest among adolescents and young adults, a new research review presented at the European Congress of Clinical Microbiology and Infectious ...
Micrograph of a clue cell (center), covered in bacteria, as compared to an unremarkable squamous cell at bottom left, and a neutrophil at bottom center. Pap stain Phase contrast microscopy of clue cells in a vaginal swab. Clue cells are epithelial cells of the vagina that get their distinctive stippled appearance by being covered with bacteria ...
