Whole genome sequencing and molecular characterization of porcine astrovirus from Haryana, India.

Porcine astrovirus (PAstV) is an enteropathogen that belongs to the family Astroviridae and the genus Mamastrovirus, and is divided into five distinct genotypes (PAstV1-PAstV5). PAstV has been reported in pigs from several countries worldwide. In India, there are limited reports of genetic characterization of PAstV.

Phylogenomic analysis of bovine astrovirus expands the known repertoire of mamastrovirus genotypes in northern India.

Bovine astrovirus (BoAstV) belongs to the family Astroviridae and the genus Mamastrovirus (MAstV). Phylogenomic analysis based on partial sequences of the RNA-dependent RNA polymerase (RdRp) gene has allowed BoAstV isolates to be classified into the genotypes MAstV-13, 24, 28-30, and 33-35. However, information about the clinical significance and molecular characteristics of BoAstV from India is restricted to a single study from western Maharashtra, India.

Detection and characterization of atypical capripoxviruses among small ruminants in India.

Recent developments in molecular biology shed light on cross-species transmission of SPPV and GTPV. The present study was planned to characterize the capripoxviruses which were circulating in the field condition among sheep and goats using RPO30 gene-based viral lineage (SPPV/GTPV) differentiating PCR and sequencing of RPO30 and GPCR genes from clinical samples. Out of 58 scabs (35 sheep and 23 goats) screened, 27 sheep and 18 goat scabs were found positive for capripox virus infections.
