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.
