Identification and Genomic Characterization of BovineA in the United States and Canada.

Abstract

is a new genus in thefamily. Boosepiviruses (BooVs) are genetically classified into three species: A, B, and C. Initially,A and B were identified in cattle, whereasC was detected in sheep. Recent evidence showed thatB was detected in sheep andC was identified in goats, suggesting thatmight cross the species barrier to infect different hosts. Different from BooV B, BooV A is less studied. In the present study, we reported identification of two North American BooV A strains from cattle. Genomic characterization revealed that US IL33712 (GenBank accession #PP035161) and Canada 1087562 (GenBank accession #PP035162) BooV A strains are distantly related to each other, and US IL33712 is more closely correlated to two Asian BooV A strains. US-strain-specific insertions, NorthAmerican-strain-specific insertions, and species A-specific insertions are observed and could contribute to viral pathogenicity and host adaptation. Our findings highlight the importance of continued surveillance of BooV A in animals.
