Bovine respiratory syncytial virus seroprevalence and risk factors in feedlot cattle from Córdoba and Santa Fe, Argentina = Seroprevalencia del virus respiratorio sincicial bovino... por Ferella, Alejandra, Perez Aguirreburualde, María Sol, Margineda, Carlos Augusto, Aznar, Maria Natalia, Sammarruco, Romina Ayelén, Dus Santos, Maria Jose, Mozgovoj, Marina Valeria

“…Positive association was found between the presence of high BRSV neutralizing antibody titers, and the following risk factors: cattle age, source of animals, presence of clinical respiratory signs and herd size. This work contributes to updating the understanding of its epidemiology in Argentinean feedlots and poses the need for reevaluating vaccination strategies against this virus in order to control infection and its impact on productivity.…”

Parasite co-infections and their impact on survival of indigenous cattle por Thumbi, Samuel M., Bronsvoort, B.M. de C., Poole, Elizabeth J., Kiara, Henry K., Toye, Philip G., Mbole-Kariuki, Mary N., Conradie, I., Jennings, A., Handel, Ian G., Coetzer, Jacobus A.W., Steyl, J.C.A., Hanotte, Olivier H., Woolhouse, Mark E.J.

“…To study effects of pathogens and their interactions on host survival, we followed 548 zebu cattle during their first year of life, determining their infection and clinical status every 5 weeks. Using a combination of clinical signs observed before death, laboratory diagnostic test results, gross-lesions on post-mortem examination, histo-pathology results and survival analysis statistical techniques, cause-specific aetiology for each death case were determined, and effect of co-infections in observed mortality patterns. …”
