Bovine dendritic cell activation, T cell proliferation and antibody responses to foot-and-mouth disease, is similar with inactivated virus and virus like particles
(Frontiers Media, 2020-09)Foot-and-mouth disease (FMD) is a highly contagious disease of cloven-hoofed animals that causes severe economic losses in the livestock industry. Currently available vaccines are based on the inactivated FMD virus (FMDV). ... -
Bovine interferon lambda Is a potent antiviral against SARS-CoV-2 infection in vitro
(Frontiers Media, 2020-11)Interferon lambda (IFN-λ) is an antiviral naturally produced in response to viral infections, with activity on cells of epithelial origin and located in the mucosal surfaces. This localized activity results in reduced ... -
Bovine leukemia virus becomes established in dairy herds before the first lactation
(2016)In this work, we studied seven groups of pregnant heifers from a consortium of dairy farms heavily infected with bovine leukemia virus (BLV). ELISA testing showed that the seroprevalence ranges of BLV in heifers between ... -
Bovine leukemia virus encoded blv-miR-b4-3p microRNA is associated with reduced expression of anti-oncogenic gene in vivo
(PLOS, 2023-02)Bovine leukemia virus (BLV) is a retrovirus that causes malignant B-cell lymphoma in up to ten-percent of infected cattle. To date, the mechanisms of BLV linked to malignant transformation remain elusive. Although BLV-encoded ... -
Bovine leukemia virus infection in neonatal calves. Risk factors and control measures
(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 ... -
Bovine leukemia virus small noncoding RNAs are functional elements that regulate replication and contribute to oncogenesis in vivo
(2016-04)Retroviruses are not expected to encode miRNAs because of the potential problem of self-cleavage of their genomic RNAs. This assumption has recently been challenged by experiments showing that bovine leukemia virus (BLV) ... -
Bovine macrophages responses to the infection with virulent and attenuated Leptospira interrogans serovar Pomona
(Elsevier, 2019-06)Leptospirosis is a zoonosis, caused by pathogenic spirochetes of the genus Leptospira. Although cattle are usually the maintenance hosts of serovar Hardjo, Pomona is the most frequent serovar circulating in Argentina. The ... -
Bovine respiratory syncytial virus seroprevalence and risk factors in feedlot cattle from Córdoba and Santa Fe, Argentina = Seroprevalencia del virus respiratorio sincicial bovino y factores de riesgo asociados en engordes a corral de Córdoba y Santa Fe, Argentina
(2018-09)Bovine respiratory syncytial virus (BRSV) is one of the causative agents of respiratory disease in cattle all over the world, leading to important economic losses. The aim of this work was to determine the seroprevalence ... -
Bovine rotavirus strains circulating in beef and dairy herds in Argentina from 2004 to 2010
(Elsevier, 2012-08-17)Bovine Group A Rotavirus (RVA) is one of the main causes of neonatal calf diarrhea worldwide. The present study reports the genotyping of bovine RVA strains circulating in Argentinean cattle from 2004 to 2010. Additionally, ... -
Bovine tuberculosis in domestic pigs: Genotyping and distribution of isolates in Argentina
(Elsevier, 2015-12)Bovine tuberculosis is caused by Mycobacterium bovis and affects primarily cattle, among many other mammal species. In this study, 250 isolates of M. bovis collected from pigs slaughtered in Argentina were typed by ... -
Brucella abortus: tipificación molecular por MLVA en aislamientos locales, análisis in silico de sus lipoproteínas e implicancia de las lipoproteínas en virulencia
(Facultad de Ciencias Exactas y Naturales, Universidad de Buenos Aires, 2016-07)La brucelosis es una enfermedad zoonótica de distribución mundial, con un alto impacto en la salud pública y en la economía. De las 10 especies de Brucella reconocidas, B. abortus es la causante de la brucelosis bovina. ... -
Brucella canis Group 2 isolated in Argentina = Brucella canis Grupo 2 aislado en Argentina
(Elsevier, 2021-06)The aim of this study was to estimate the diversity and prevalence of both groups of Brucella canis 1 and 2 with and without deletion respectively in different areas of Argentina. A total of 104 bacterial cultures were ... -
Brucella spp. Lumazine synthase as a novel immunomodulator to produce egg yolk antibodies
(Scientific Research, 2012-02)Lumazine synthase from Brucella spp. (BLS) is a highly immunogenic decameric protein. It has been previously described as a carrier of peptides or proteins to increase their immunogenicity in different animal species, but ... -
Búsqueda de Leptospira spp. en visón americano Neogale vison (Schreber, 1777) en el sur de la provincia de Neuquén, Patagonia Argentina
(Sociedad Argentina para el Estudio de los Mamíferos, 2023)Los mamíferos domésticos y silvestres cumplen un rol importante en la epidemiología de la leptospirosis. El visón americano Neogale vison es un mustélido introducido en Argentina que podría actuar como portador/reservorio ... -
