Abstract Two cases of coinfection with bovine papular stomatitis virus (BPSV) and pseudocowpox virus (PCPV) in dairy calves in Tochigi Prefecture, Japan, are reported. Sequences of BPSV and PCPV were simultaneously detected in the same polymerase chain reaction (PCR) amplicons, which were obtained from the DNA of two dairy calves using a pan-parapoxvirus primer set. PCR amplification using BPSV- and PCPV-specific primer sets were able to distinguish between the two viruses in coinfected clinical samples. Based on these data, further studies on the occurrence BPSV/PCPV coinfections in cattle in Japan are warranted. The parapoxviruses (PPVs) (family Poxviridae) include bovine papular stomatitis virus (BPSV), pseudocowpox virus (PCPV), orf virus (ORFV), and PPV of red deer in New Zealand [1]. PPV infections are widespread in ruminants and usually characterized by mild clinical signs around the mouth or on the teats of affected animals [2, 3]. These infections need to be differentiated from other serious diseases affecting the oral cavity and skin, such as footand-mouth disease (FMD), or from other mucocutaneous viruses, because in some cases they have similar clinical Handling Editor: William G Dundon.

signs [4, 5]. PPVs occasionally infect humans after close contact with skin lesions of infected animals or after handling virus-contaminated materials. PPV induces so-called milker’s nodules or human orf on the skin of human hands and fingers [6, 7]. In Japan, a serological survey of PPV infection indicated that 72% (1310/1819) of cattle in 27 prefectures were seropositive [8]. Several cases of BPSV infection have been previously reported in cattle in Japan [9–11], but only a few cases of PCPV infection have been reported [11, 12]. Although BPSV and PCPV have been successively detected in the same calf [13], the epidemiological situation with regard to PCPV infection in cattle in Japan remains unclear. In this study, two cases of coinfection with BPSV and PCPV in dairy calves in Tochigi Prefecture,
