Abstract

Avian orthoreovirus infections are increasingly common in Peruvian broiler chickens, primarily causing arthritis/tenosynovitis syndrome. In this study, sequencing and phylogenetic analysis of the σC gene revealed that avian orthoreovirus isolates were clustered in genotypes 1, 2, and 3. However, further research is needed to understand its genetic diversity and improve vaccination strategies.

Keywords: Avian orthoreovirus; Nanopore Sequencing; Peru; phylogenetic; poultry; viral arthritis; σC gene.
