Sarcina cells, for example, are arranged in cubical pockets because cell division alternates regularly among the three perpendicular planes. Streptococcus spp. resemble a string of beads because division always occurs in the same plane. Some of these strings, for example, S. pneumoniae, are only two cells long.
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 ...

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 ...
Some functions of the type IV pili include: mediating attachment to various cells and tissues, twitching motility, natural competence, microcolony formation, extensive intrastrain phase, and antigenic variation. Neisseria bacteria have also been shown to be an important factor in the early stages of canine plaque development. [2]
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]
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.
