Bovine colostral cells : the often forgotten component of colostrum
(American Veterinary Medical Association, 2017-05)Because bovine maternal and fetal blood supplies are kept separate in utero, calves are immunologically naïve immediately after birth, which puts them at high risk for disease. The acquisition of passive immunity, generally ... -
Enhanced sensitivity in detection of antiviral antibody responses using biotinylation of foot-and-mouth disease virus (FMDV) capsids
(Elsevier, 2017-11)Analysis of the immune response to infection of livestock by foot-and-mouth disease virus (FMDV) is most often reported as the serum antibody response to the virus. While measurement of neutralizing antibody has been ... -
Minimally processed crude leaf extracts of Nicotiana benthamiana containing recombinant foot and mouth disease virus-like particles are immunogenic in mice
(Elsevier, 2018-12)Foot-and-mouth disease (FMD) remains one of the most feared viral diseases affecting cloven-hoofed animals, and results in severe economic losses. Currently available vaccines are based on inactivated FMD virus (FMDV). The ... -
Estrés en ganado: causas y consecuencias = Stress in productive animals: causes and consequences
(Universidad Nacional del Nordeste. Facultad de Ciencias Veterinarias, 2017)En los últimos años se está dando una importancia creciente a las normas sobre bienestar animal debido a la confluencia de varios factores, como el mayor conocimiento en distintas disciplinas relacionadas con los animales ... -
Relevamiento serológico de anticuerpos contra enfermedades virales de interés sanitario en llamas (Lama glama) de la provincia de Jujuy, Argentina = Serological survey of antibodies against viral diseases of public health interest in llamas (Lama glama) from Jujuy province, Argentina
(Asociación Argentina de Microbiología, 2014-03)Las poblaciones de llamas de Argentina se concentran principalmente en la provincia de Jujuy; su explotación representa un importante recurso económico de las comunidades altoandinas. El objetivo de este trabajo fue evaluar ... -
Detection of bovine herpesvirus 2 and bovine herpesvirus 4 DNA in trigeminal ganglia of naturally infected cattle by polymerase chain reaction
(Elsevier, 2014-06-25)Establishment of latent infection within specific tissues in the host is a common biological feature of the herpesviruses. In the case of bovine herpesvirus 2 (BoHV-2), latency is established in neuronal tissues, while ... -
Early protection against foot-and-mouth disease virus in cattle using an inactivated vaccine formulated with Montanide ESSAI IMS D 12802 VG PR adjuvant
(Elsevier, 2014-04-17)Foot and mouth disease is an acute disease of cattle with a broad distribution around the world. Due to the fast spread of FMDV infections, control measures must be applied immediately after an outbreak, such as the use ... -
Accuracy of traditional and novel serology tests for predicting cross-protection in foot-and-mouth disease vaccinated cattle
(Elsevier, 2014-01-16)Foot-and-mouth disease virus (FMDV) antigenic-match between vaccine and field viruses has traditionally been estimated in vitro by computing the r1 value using virus neutralization test (VNT) or ELISA titers. In this study ... -
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 ... -
Novel vaccination approaches against equine alphavirus encephalitides
(Elsevier, 2014-01-09)The current production of inactivated vaccines for the prevention of equine alphavirus encephalitides caused by Eastern, Western and Venezuelan Equine Encephalitis viruses (EEEV, WEEV, VEEV) involves the manipulation of ... -
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, ... -
Discovery and molecular characterization of a group A rotavirus strain detected in an Argentinean vicuña (Vicugna vicugna)
(Elsevier, 2013-01-25)The wild vicuña (Vicugna vicugna) is one of the four species of native South American camelids (SACs) in addition to the wild guanaco, and their domesticated counterparts, alpaca and llama, respectively. Serological data ... -
Efficacy of a BVDV subunit vaccine produced in alfalfa transgenic plants
(Elsevier, 2013-02-15)Bovine viral diarrhea virus (BVDV) is considered an important cause of economic loss within bovine herds worldwide. In Argentina, only the use of inactivated vaccines is allowed, however, the efficacy of inactivated BVDV ... -
Co-inoculation of baculovirus and FMDV vaccine in mice, elicits very early protection against foot and mouth disease virus without interfering with long lasting immunity
(Elsevier, 2013-05-31)Baculoviruses (Bvs) potentiate the immune response against soluble antigens. We investigated whether Bv could be used as immunoactivator in foot-and-mouth disease (FMD) vaccines using the BALB/c mouse model. Mice were ... -
Comparison of strategies for the production of FMDV empty capsids using the Baculovirus Vector System
(Springer, 2014-11)Recombinant FMDV empty capsids have been produced in insect cells and larvae using the baculovirus expression system, although protein yield and efficiency of capsid assembly have been highly variable. In this work, two ... -
Protection induced by a glycoprotein E-deleted bovine herpesvirus type 1 marker strain used either as an inactivated or live attenuated vaccine in cattle
(BMC, 2014-01)Background: Bovine herpesvirus type 1 (BoHV-1) is the causative agent of respiratory and genital tract infections; causing a high economic loss in all continents. Use of marker vaccines in IBR eradication programs is widely ... -
Comparison of transient and stable expression of foot-and-mouth disease virus capsid proteins in mammalian cells
(Scientific Research, 2013-12)Foot-and-mouth disease is a highly contagious disease that produces severe economic losses in the livestock industry. This disease is being controlled by the use of an inactivated vaccine. However, the use of recombinant ... -
