ABSTRACT

Enteric infections foist massive losses in commercial and backyard poultry sector. Rotavirus, the leading cause of enteric infections, is of great concern among researchers and industry, as the epidemiological reports confirm that new rotavirus groups are evolving in poultry and might inflict the growing poultry sector in the coming years. The diversity and epidemiology in avian group A rotaviruses throughout the world have been studied by several researchers, but epidemiological studies are barely accessible for other groups of rotaviruses like D, F and G. A timely identification of rotavirus is, therefore, critical for control of disease and to minimize losses to the poultry sector. Therefore, the frequency distribution of avian RVD infection in northern and southern states of India was ascertained by using RNA-PAGE and a RT-PCR assay. RVD was detected in 6.04% (13/215) of the intestinal contents examined during January 2012 to January 2013. The results confirm the existence of RVD in chicken of temperate northern India. Sequence based inquiry confirmed higher homology with existing type D avian rotavirus isolates from rest of the world. Thus, an understanding of the viruses that cause gastrointestinal tract disease in poultry, along with an understanding of their epidemiology is necessary for the development of be?fitting control measures.
