This study reported field outbreaks of bovine viral diarrhoea virus (BVDV) infection, either alone or mixed with bovine herpesvirus-1 (BHV-1) and/or parainfluenza-3 virus (PI-3V) in Egypt during 2000. In Lower Egypt, young calves in three cattle herds in El-Minufiya Province, El-Fayoum Province and in governmental quarantine in El-Behira Province, showed symptoms of enteritis, either alone or accompanied by respiratory manifestations. The affected herds were visited and the diseased animals were clinically examined. Many epidemiological aspects, such as morbidities, mortalities and case fatalities, as well as the abortive rate, were calculated. Ethylenediamine tetra-acetic acid-blood samples, sterile nasal swabs and serum samples were obtained for virological and serological diagnosis. The laboratory investigations revealed that the main cause of calf mortalities in the three herds was infection with BVDV, either alone, as on the El-Minufiya farm, or mixed with PI-3V, as on the El-Fayoum farm, or mixed with both BHV-1 and PI-3V, as in the herd in governmental quarantine in El-Behira Province.
