“Sequencing 72 avian reovirus isolates from Pennsylvania broiler flocks (2017-2022) found six genetically distinct genotype clusters circulating, with genotype V most common (33%) and amino acid identity to the commercial vaccine strains (1133, 1733, 2408, 2177) as low as 45%. Current vaccines are poorly matched to most field variants, so ongoing genotyping and autogenous/updated vaccine strategies are needed for reovirus control in broilers.”

“Of 301 avian reovirus isolates from Pennsylvania broiler and turkey flocks (2011–2014), 78% of the 114 sequenced strains fell into genotype clusters distinct from the S1133, 1733 and 2048 vaccine strains — including a brand-new cluster 6 — helping explain why vaccinated flocks still saw 20–40% morbidity, up to 10% mortality, arthritis/tenosynovitis and stunting. Existing commercial vaccines likely offer poor protection against these variants, so autogenous or updated vaccines should be considered.”
