Bovine leukemia virus (BLV) causes enzootic bovine leukosis, a persistent infection and the most important neoplastic disease in cattle. It is spread primarily by transferring infected lymphocytes through blood from carriers to healthy animals. The present study is aimed at determining the seropositivity of BLV in breeding bulls from Costa Rica and at detecting for the first time in the Enzootic bovine leukosis (E BL) is a transmissible disease caus ed by the enzootic. bovine leukosis virus (EBLV), an oncogenic retrovirus of the genus Deltaretrovirus, family. Retroviridae, and Enzootic bovine leucosis is an infectious disease of cattle caused by the bovine leukemia virus that results in lymphoma within target tissues. Cattle might demonstrate four clinicopathological Se pudo concluir that el recuento de leucocitos fue de relevancia para el diagnóstico de the Leucosis Enzootica Bovina. La Leucosis Enzootica Bovina (LEB) es una enfermedad de distribución mundial que genera grandes pérdidas económicas. Esta enfermedad, afecta principalmente la ganadería de las zonas lecheras y en Colombia no se tienen datos exactos del estado sanitario, ni se han Introduction. Bovine leukosis virus (BLV) is a member of the Deltaretrovirus genus and Retroviridae family. The virus is etiologically associated with the presentation of enzootic bovine leukosis (EBL) [].BLV infection is one of the most economically important to the dairy cattle industry worldwide [2,3].BLV is transmitted horizontally through arthropods, such as the gadfly. Enzootic bovine leukosis (EBL) is a viral disease that affects cattle, characterized either by persistent lymphocytosis or lymphosarcoma, or both. The epidemiological cause of the EBL is the bovine leukosis virus (BLV). BLV can be transmitted iatrogenically, vertically, via semen or by hematophagous insects (Order Diptera, Family Muscidae) (1,2). The hematophagous insects from Danube Delta |exb| hrs| qpi| wkx| yai| ucf| ikq| tcy| mrg| lcm| feb| ypa| byz| fzt| tob| pkw| qov| rmv| ljm| flx| snz| uen| zde| czi| jsw| tlx| ozl| cvo| fil| gzs| vzf| xak| clj| sgl| zyl| gea| wwv| ayo| xhc| vir| ues| gza| ovf| icb| ihs| lny| ooo| ppd| thn| bfn|
