(Ediciones Taurus, 2020-08)Los objetivos del presente trabajo fueron determinar 1) el efecto de un tratamiento con FSH y 2) el período del ciclo estral (metaestro= primera onda folicular o diestro= segunda onda folicular) durante el crecimiento de ... -
Cathelicidin bovine myeloid antimicrobial peptide (BMAP) 28 is involved in the inflammatory response against alpha-herpesviruses in the bovine nervous system
(Elsevier, 2020-06)The role of the local innate immune response in the neuropathogenesis of bovine herpesvirus (BoHV) type 1 and 5 remains largely unknown. This study determined the gene transcriptional expression of relevant bovine ... -
Characterization of the first bovine gammaherpesvirus 4 strain isolated from an aborted bovine fetus in Argentina
(Springer Verlag, 2020-01-24)Bovine herpesvirus 4 (BoHV-4) is increasingly believed to be responsible for several disorders of the bovine reproductive tract. The first characterization of BoHV-4 in Argentina was from samples from an aborted fetus. ... -
Editorial: Infectious diseases affecting reproduction and the neonatal period in cattle
(Frontiers Media, 2021-04-22)Even with the global scenario after the SARS CoV-2 pandemic, human population keeps growing, and therefore food safety and quality demand is increasing. So, it is required to improve the efficiency in most livestock ... -
Effect of Campylobacter fetus on in vitro fertilization and embryonic development of preimplantation bovine embryos
(Elsevier, 2024-01)Campylobacter fetus is an important veterinary pathogen that causes campylobacteriosis. This disease causes decreased productivity of cattle by inducing reproductive losses. Although several virulence factors have been ... -
Fotosensibilización primaria por consumo de Ammi majus en bovinos: primer reporte en Argentina
(Facultad de Ciencias Veterinarias, Universidad Nacional del Nordeste, 2018-09)Se describe un brote de fotosensibilización primaria en bovinos causado por el consumo de Ammi majus. Los animales manifestaron fotofobia, epífora, opacidad corneal bilateral y dermatitis en pezones, vulva y morro. Se ... -
Free cholesterol and cholesterol esters in bovine oocytes: Implications in survival and membrane raft organization after cryopreservation
(2017)Part of the damage caused by cryopreservation of mammalian oocytes occurs at the plasma membrane. The addition of cholesterol to cell membranes as a strategy to make it more tolerant to cryopreservation has been little ... -
Improvement of Leptospira spp. diagnosis in aborted bovine fetuses by qPCR
(Elsevier, 2020-09)Leptospirosis is a disease with major economic impact on livestock industry. The objective of this work was to determine the presence of Leptospira spp. DNA by qPCR in bovine fetuses with presumptive diagnosis of leptospirosis ... -
Isolation of Campylobacter fetus subsp. venerealis from seminal vesicle of a naturally challenged bull
(Springer Verlag, 2021-09-03)Campylobacter fetus is a well-recognized pathogen that affects reproductive rate in cattle. In the present study, two Angus bulls were kept (39 days) separately with a group of heifers experimentally infected withCampylobacter ... -
