Various infectious agents responsible for causing diarrhoea include viruses, bacteria and parasites. Diarrhoea in calves during 5-10 days of age is commonly due to rotavirus and infected calves excrete very large quantities of virus particles in their faeces and become potential source of infection to other animals. Recognition of significant morbidity and mortality caused by rotavirus in neonatal calves has stimulated studies for definitive diagnosis of the disease as well as molecular typing of the circulating viruses with the ultimate goal of developing effective methods of preventive measures.enVeterinary MicrobiologyAnalysisThesis
