Fimbriosis, also known as anaplasmosis, is an infectious blood parasite transmitted by marginal anaplasmosis via ticks that exclusively parasitises red blood cells. It mainly causes disease in ruminants, horses, humans, dogs and cats.
Clinical signs of Anaplasma canis
Infection with Anaplasma is generally chronic, the beginning does not show obvious clinical symptoms when the resistance drops, high fever, anaemia, gangrene and progressive wasting and other symptoms, acute onset of the disease can lead to animal death. In addition, the severity of clinical symptoms after canine anaplasmosis infection may also be related to the different strains of anaplasmosis, and the haematological examination of the animals suffering from siderophagy shows a significant decrease in the number of erythrocytes, the erythrocyte pressure volume and the haemoglobin content.
Route of transmission
Anaplasma is transmitted primarily by hard ticks; other vectors also include a variety of blood-sucking insects such as gadflies, flies and mosquitoes. Anaplasma is transmitted by biting a host animal that carries the pathogen and then biting other healthy animals. In addition, free-range farming practices can increase the risk of infection between animals, and the onset of Anaplasma occurs during the active season for ticks and bloodsucking insects, with the peak of transmission occurring in August-October.
