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 ... -
Evaluation of total white blood cell count as a marker for proviral load of bovine leukemia virus in dairy cattle from herds with a high seroprevalence of antibodies against bovine leukemia virus
(2013-05)Objective—To determine the reference interval for WBC counts in Holstein dairy cows from herds with high seroprevalence for anti–bovine leukemia virus (BLV) antibodies, analyze the correlation of total WBC counts and blood ... -
Dynamics of perinatal bovine leukemia virus infection
(BioMed Central, 2014)Bovine leukemia virus (BLV) is highly endemic in many countries, including Argentina. As prevention of the spread from infected animals is of primary importance in breaking the cycle of BLV transmission, it is important ... -
Comparative histopathological and immunological study of two field strains of chicken anemia virus
(BioMed Central, 2014-10)Infection of poultry with chicken anemia virus (CAV) is implicated in several field problems in broiler flocks due to the immunosuppression generated and, consequently, the increased susceptibility to secondary infections. ... -
Controlling Rotavirus-associated diarrhea: Could single-domain antibody fragments make the difference? = Hacia el control de la diarrea por rotavirus A: ¿podrían los nanoanticuerpos VHH marcar la diferencia?
(Asociación Argentina de Microbiología, 2015-10)Group A Rotavirus (RVA) remains a leading cause of severe diarrhea and child mortality. The variable domain of camelid heavy chain antibodies (VHH) display potent antigen-binding capacity, have low production costs and are ... -
The efficacy of ELISA commercial kits for the screening of equine infectious anemia virus infection = Eficacia de ensayos de ELISA comerciales para el screening de infección por el virus de la anemia infecciosa equina
(Elsevier España, 2015-03)The most used and reliable indicator of equine infectious anemia virus (EIAV) infection is the detection of its specific antibodies in horse serum. In the present study, the performance of two commercial ELISA tests for ... -
