Protective effect against intraerythrocytic merozoites of Theileria sergenti infection in calves by passive transfer of monoclonal antibody.

Passive protective effect of anti-K99 antibodies against enterotoxigenic E.coli infection in neonatal calves

BACKGROUND: BACKGROUND: Enterotoxigenic Escherichia coli (ETEC) is the main causative agents of neonatal calf diarrhea. Passive transfer of antibodies that is derived from the dams of the calves through their colostrum plays an important role in disease prevention. OBJECTIVES: To determine the presence of natural specific antibodies against K99 antigen in dam’s serum and colostrum as well as in...

Protection against murine cytomegalovirus infection by passive transfer of neutralizing and non-neutralizing monoclonal antibodies.

The ability of eight neutralizing monoclonal antibodies (MAbs) specific for structural proteins of murine cytomegalovirus (MCMV) to protect mice passively against MCMV infection was examined to determine firstly whether a correlation existed between the neutralization titres of the MAbs in vitro and the protection afforded by the MAbs in vivo and, secondly, the contribution of the host towards ...

Prevalence of Theileria sergenti infection in Korean native cattle by polymerase chain reaction.

This study was performed to investigate the prevalence of theileriosis and to compare the prevalence of this disease in Korean native cattle reared under different environmental conditions, namely, in a grazing area and a non-grazing area by polymerase chain reaction. Three hundred and one Korean native cattle (276 cows and 25 bulls) that had not received prior treatment or been vaccinated to p...
