A 2-year-old East Friesian sheep imported from Australia exhibited severe anemia after contagious pustular dermatitis in Hokkaido, Japan. Hemoplasma infection was confirmed in blood smears. Both Mycoplasma ovis and 'Candidatus Mycoplasma haemovis' were detected by PCR and sequence analyses. In the epidemiological analysis, dual pathogens were detected in 6 of 12 (50.0%) sheep imported from Australia with the infected ewe at the same time, 1 of 5 (20.0%) sheep introduced from a domestic farm in Hokkaido, and in 1 of 16 (6.3%) sheep from an epidemiologically unrelated ranch. It is the first clinical case of sheep to confirm coinfection of these pathogens in Japan.
一只从澳大利亚进口的2岁东弗里生绵羊在日本北海道感染传染性脓疱性皮炎后出现严重贫血。血液涂片证实有血支原体感染。通过聚合酶链反应(PCR)和序列分析检测到了绵羊支原体和“嗜血性支原体候选种”。在流行病学分析中,从澳大利亚进口的12只绵羊中有6只(50.0%)与感染母羊同时检测到双重病原体,从北海道一家国内农场引进的5只绵羊中有1只(20.0%)检测到双重病原体,在一个与流行病学无关的牧场的16只绵羊中有1只(6.3%)检测到双重病原体。这是日本首例证实这些病原体合并感染的绵羊临床病例。
