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.
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]
All are spherical or nearly so, but they vary considerably in size. Members of some genera are identifiable by the way cells are attached to one another: in pockets, in chains, or grape-like clusters. These arrangements reflect patterns of cell division and that cells stick together.
MALDI-TOF (Matrix-assisted laser desorption/ionization - time of flight) is a specific type of mass spectrometry that is able to identify microorganisms. A pure culture is isolated and spread directly on a stainless steel or disposable target. The cells are lysed and overlaid with a matrix, which forms protein complexes with the bacterial proteins.
Cases of gonorrhea — the second most common STI — are skyrocketing in the U.S.
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 ...
