Illustration of venereal granulomata on a dog's penis. A canine transmissible venereal tumor (CTVT), also known as a transmissible venereal tumor (TVT), canine transmissible venereal sarcoma (CTVS), sticker tumor and infectious sarcoma, is a histiocytic tumor of the external genitalia of the dog and other canines, and is transmitted from animal to animal during mating.
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]
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 ...
Gametes are part of the sexual stages, and they can invade other cells. Male gametes divide and break out to the host cell, then go invade cells containing the female gamete. Once the male gametes and the female gamete are in the same host cell, they will fuse creating a zygote. The zygote develops into an oocyst. The oocyst then breaks out of ...
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.

Histiocytic diseases in dogs are a group of diseases in dogs which may involve the skin, and which can be difficult to differentiate from granulomatous, reactive inflammatory or lymphoproliferative diseases. The clinical presentation and behaviour as well as response to therapy vary greatly among the syndromes.
Domestic dogs in Belgium showed a mean prevalence of T. canis of 4.4%, those from larger kennels of up to 31%. [6] In domestic dogs in Serbia, T. canis was detectable in 30% of the animals, [7] in herding and hunting dogs in Greece in 12.8% and T. leonina in 0.7% of animals. [8]
These pumps are proton antiporters where the antibiotic is pumped out of the cell while a proton is pumped into the cell. [9] The cell wall of N. gonorrhoeae contains porins which are holes within the cell wall in which some molecules are able to diffuse into or out of the cell membrane. This mechanism falls under the first general mechanism ...
