Bovine leukemia virus infection in neonatal calves. Risk factors and control measures
Ruiz, Vanesa; Porta, Natalia Gabriela; Lomonaco, Marina; Trono, Karina Gabriela; Alvarez, Irene (Frontiers Media, 2018-10)Bovine leukemia virus (BLV) is the causative agent of enzootic bovine leukosis (EBL). Although efficient eradication programs have been successfully implemented in most European countries and Oceania, BLV infection rates ... -
Detection of bovine leukemia virus RNA in blood samples of naturally infected dairy cattle
Alvarez, Irene; Porta, Natalia Gabriela; Trono, Karina Gabriela (MDPI, 2019-09)The viral expression in vivo, in bovine leukemia virus (BLV)-infected cattle, is considered to be restricted to extremely low levels, and the mitosis of infected B lymphocytes is regarded as the main mode of virus persistence ... -
Efficacy of the spray-drying treatment to inactivate the bovine leukemia virus in bovine colostrum
Lomonaco, Marina; Sowul, Mariana; Gutierrez, Gerónimo; Malacari, Darío Amilcar; Alvarez, Irene; Porta, Natalia Gabriela; Zabal, Osvaldo Alfredo; Trono, Karina Gabriela (Elsevier, 2020-07)Previous studies have shown the presence of bovine leukemia virus (BLV) in colostrum and milk of naturally infected cows. The relationship between virus or provirus and specific antibodies in these secretions is particular ... -
Experimental infection of sheep with bovine leukemia virus (BLV): minimum dose of BLV-FLK cells and cell-free BLV and neutralization activity of natural antibodies = Infección experimental en ovinos con el virus de leucosis bovina: dosis mínima de células BLV-FLK y virus libre de células, y actividad neutralizante de anticuerpos naturales
Porta, Natalia Gabriela; Alvarez, Irene; Suarez Archilla, Guillermo Alejandro; Ruiz, Vanesa; Abdala, Alejandro Ariel; Trono, Karina Gabriela (Elsevier España, 2019-12)Bovine leukemia virus (BLV) is an important cattle pathogen that causes major economic losses worldwide, especially in dairy farms. The use of animal models provides valuable insight into the pathogenesis of viral infections. ... -
Seroprevalence and risk factors associated with bovine Leukemia virus infection in argentine beef cattle
Porta, Natalia Gabriela; Suarez Archilla, Guillermo; Miotti, Camila; Molineri, Ana Ines; Alvarez, Irene; Trono, Karina Gabriela; Signorini Porchiett, Marcelo Lisandro; Ruiz, Vanesa (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 ... -
