Novel group A rotavirus G8 P[1] as primary cause of an ovine diarrheic syndrome outbreak in weaned lambs

2011

International audience; Rotavirus is a worldwide major cause of diarrhea outbreaks in neonatal ruminants. An outbreak of ovine diarrheic syndrome (ODS) in 50-75 days-old lambs (weaned lambs) is described. Fecal immunochromatography and intestinal immunohistochemistry for rotavirus group A were performed. In addition, semi-nested multiplex RT-PCR for G and P rotavirus genotyping in combination with sequencing were performed, to support the diagnosis and identify the viral strain. A novel ovine rotavirus group A G8 P[1] strain was determined as the main cause of the ODS observed, whereas other pathogens were ruled out.
