Anaplazmoza bydła

Anaplasmosis is an infectious but non-contagious disease of cattle, sheep, goats and wild ruminants caused by Anaplasma sp. (Rickettsiales - Anaplasmataceae). In cattle Anaplasma marginale is the main etiological agent, transmitted by ticks. A worldwide disease, anaplasmosis is characterized by fever, anemia, icterus and body weight loss. It has great economic importance in cattle husbandry, especially in tropical and subtropical regions. In 2001 the taxonomy of the order Rickettsiales comprising Anaplasma sp. and other genera in the families Rickettsiaceae and Anaplasmataceae were significantly reorganized. Disease prevalence, etiology, epidemiology, pathogenesis, clinical signs, anatomopathological lesions, diagnosis, treatment, control methods and prophylaxis, especially specific immunoprophylaxis, are discussed in the paper.
