Genome-wide scan for commons SNPs affecting bovine leukemia virus infection level in dairy cattle
(2018-02-13)Background: Bovine leukemia virus (BLV) infection is omnipresent in dairy herds causing direct economic losses due to trade restrictions and lymphosarcoma-related deaths. Milk production drops and increase in the culling ... -
Influencia de las condiciones de incubación en la detección de anticuerpos contra el Virus de la Leucosis bovina por ELISA = Influence of the incubation conditions on the detection of antibodies to bovine leukemia virus by ELISA
(Sociedad de Medicina Veterinaria, 2013-05)En este trabajo se modificaron las condiciones de incubación del ensayo de ELISAp24 que detecta anticuerpos contra el Virus de la Leucosis bovina, con el propósito de evaluar si se reduce el número de resultados falsos y ... -

(Universidad Nacional del Centro de la Provincia de Buenos Aires, 2023-08)Virus de la leucosis bovina (BLV). Familia: Retroviridae , Genero: Deltaretrovirus , Genoma: ssRNA. Agente causal de la Leucosis bovina enzoótica. Prevalencia predial: Tambos 80 99 Establecimientos de producción de carne ... -
Recent advances in BLV research
(MDPI, 2015-11)Different animal models have been proposed to investigate the mechanisms of Human T-lymphotropic Virus (HTLV)-induced pathogenesis: rats, transgenic and NOD-SCID/γcnull (NOG) mice, rabbits, squirrel monkeys, baboons and ... -
Seroprevalence and risk factors associated with bovine Leukemia virus infection in argentine beef cattle
(Elsevier, 2023-11)Bovine leukemia virus (BLV) is the causative agent of enzootic bovine leukosis, an endemic disease in dairy cattle of Argentina. However, little is known about the seroprevalence of BLV in beef cattle. In this study, we ... -
Seroprevalencia de infección por el virus de leucosis bovina durante 2015 en rodeos de cría de la Zona Deprimida del Río Salado, provincia de Buenos Aires, Argentina
(2017-06)La leucosis enzoótica bovina (LEB) es una enfermedad crónica, linfoproliferativa y altamente contagiosa producida por el virus de la leucosis bovina (VLB). La sangre es una fuente importante de infección, principalmente ... -
Seroprevalencia de leucosis enzoótica bovina en tambos del sur de la provincia de Córdoba, Argentina = Seroprevalence of enzootic bovine leucosis in dairy farms in the south of the province of Córdoba, Argentina
(2019-03)La Leucosis Enzoótica Bovina (LEB) afecta al tejido linfoide y el rasgo patológico distintivo es la transformación neoplásica de linfocitos B, su frecuencia es predominante en el ganado lechero adulto. Existen pocos estudios ... -
Short communication: Relationship between the level of bovine leukemia virus antibody and provirus in blood and milk of cows from a naturally infected herd
(2016)We explored the relationship between the level of bovine leukemia virus antibodies and provirus load during natural infection. For that purpose, a set of 50 blood and milk paired samples were analyzed for the presence of ... -
Spontaneous virus reactivation in cattle chronically infected with bovine leukemia virus
(BioMed Central, 2019)Background: The absence of virus expression during the chronic stage of bovine leukemia virus (BLV) infection and its reactivation upon ex vivo culture has become a long-lived Dogma. During the chronic stage of BLV ... -
Stable infection of a bovine mammary epithelial cell line (MAC-T) with bovine leukemia virus (BLV)
(Elsevier, 2018)Bovine leukemia virus (BLV) is a retrovirus that affects cattle causing a lymphoproliferative disease. BLV infection has been associated with misbalance of the immune response causing a higher incidence of other infections. ... -
Toll-like receptors, IFN-γ and IL-12 expression in bovine leukemia virus-infected animals with low or high proviral load
(Elsevier, 2016-08)Bovine leukemia virus (BLV) infection is widespread mainly in dairy cattle and 5–10% of infected animals will die due to lymphosarcoma; most cattle remain asymptomatic but 30% develop persistent lymphocytosis (PL). BLV ... -
Vaccination against δ-retroviruses : the bovine leukemia virus paradigm
(2014-06)Bovine leukemia virus (BLV) and human T-lymphotropic virus type 1 (HTLV-1) are closely related d-retroviruses that induce hematological diseases. HTLV-1 infects about 15 million people worldwide, mainly in subtropical ...
