Bovine colostral cells—the often forgotten component of colostrum
(American Veterinary Medical Association, 2017-05)At birth, neonatal calves have all the essential immune components they need as adult cattle; however, it takes at least 2 to 4 weeks for those components to become fully functional.1,2 The immune system does not become ... -
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 ... -
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 ... -
Efficacy of prepartum vaccination against neonatal calf diarrhea in Nelore dams as a prevention measure
(BioMed Central, 2022-08)Background: Neonatal calf diarrhea (NCD) is the leading cause of calf morbidity and mortality in beef cattle. Cow’s vaccination in last stage of pregnancy is one of the most important measures to mitigate the risk of NCD ... -
Heterogeneity in the antibody response to foot‐and‐mouth disease primo‐vaccinated calves
(2015-06)Foot‐and‐mouth disease (FMD) vaccines are routinely used as effective control tools in large regions worldwide and to limit outbreaks during epidemics. Vaccine‐induced protection in cattle has been largely correlated with ... -
Immune cells transferred by colostrum do not influence the immune responses to foot-and-mouth disease primary vaccination
(Elsevier, 2019-09)Little is known about the influence of maternal antibodies and immune cells transferred through colostrum on the immune responses of calves to the currently used foot-and-mouth disease (FMD) vaccines. Here we evaluated the ... -
In vitro and in vivo characterization of a typical and a high pathogenic bovine viral diarrhea virus type ii strains
(Frontiers Media, 2018-04)Non-cytopathic (ncp) type 2 bovine viral diarrhea virus (BVDV-2) is widely prevalent in Argentina causing high mortality rates in cattle herds. In this study, we characterized an Argentinean ncp BVDV-2 field isolate (98-124) ... -
Influence of antibodies transferred by colostrum in the immune responses of calves to current foot-and-mouth disease vaccines
(2014-11-12)Immunity to currently used oil-adjuvanted inactivated vaccines against foot-and-mouth disease virus (FMDV) has been studied in detail in adult animals; however, the influence of maternally derived antibodies transferred ... -
Passive immunity to control Bovine coronavirus diarrhea in a dairy herd in Argentina = Inmunidad pasiva en el control de la diarrea por coronavirus bovino en un rodeo lechero de Argentina
(2018)Bovine coronavirus (BCoV) is a viral enteric pathogen associated with calf diarrhea worldwide being, in Argentina, mostly detected in dairy husbandry systems. The aim of the present work was to study if maternal IgG1 ...
