ABSTRACT
Whole-genome sequencing of a virus isolated from Culicoides biting midges in southern Japan in 2020 revealed that it is a strain of Balagodu virus (BLGV; genus Orthobunyavirus; family Peribunyaviridae; order Bunyavirales). A solitary instance of BLGV isolation occurred in India in 1963. All assembled segments comprise complete protein-coding sequences that are similar to those of other orthobunyaviruses. The consensus 3'- and 5'-terminal sequences of orthobunyaviruses' genomic RNAs are also conserved in the Japanese BLGV strain. Here, we update the geographic distribution of BLGV and provide its complete sequence, contributing to the clarification of orthobunyavirus phylogeny.
ABSTRACT
We detected parapoxviruses from environmental samples and calves with and without intraoral clinical signs and conducted molecular and serological analyses. Pseudocowpox virus (PCPV) was detected from a calf showing anorexia, frothy salivation, and erosion in the mucosa of the lip and tongue. At the time that PCPV was detected, bovine papular stomatitis viruses (BPSVs) were detected in environmental samples as well as in calves without intraoral clinical signs. BPSV, but not PCPV, was detected in the same calf after 22 days. Phylogenetic analysis revealed that genetically different PCPV strains exist in Japan. This is the first report on the detection of PCPV and BPSV sequentially in the same calf and coexistence of PCPV and BPSV in the same farm in Japan.
