Studies on the ecology of pathogenic Bartonella species in wildlife

调查发现，日本57.8%(26/45)的野鹿血液中至少含有两种巴尔通体。由于巴尔通体的高流行率，鹿科动物在巴尔通体的传播中起到了一定的作用。从1只日本獾(6.7%)和1只日本貂(12.5%)中分离到巴尔通体细菌。序列分析表明，从獾分离到的菌株(JB-15)可以代表一个新的巴尔通体种，而从貂皮中分离到的分离株(JM-1)与巴尔通体关系密切。这是从獾和貂皮中分离巴尔通体的首次报道。从冲绳圈养野生猫鼬和千叶县的果子狸中分离到亨氏巴尔通体的比例分别为15.9%(10/63)和3.8%(1/26)。提示这两种动物可能是猫抓病的感染源。

It was found that 57.8% (26/45) of wild deer in Japan harbor at least two Bartonella species in their blood. It is suggested that deer keds contribute in the transmission of the Bartonella species because of high prevalence of Bartonella. Bartonella bacteria were isolated from one Japanese badger (6.7 %) and from one Japanese marten (12.5%). The sequence analysis indicated that the isolate derived from the Japanese badger (strain JB-15) can represent a novel Bartonella species and the isolate from the Japanese marten (strain JM-1) was closely related to Bartonella washoensis. This is the first report on isolation of Bartonella from badger and marten. Bartonella henselae was isolated from 15.9% (10/63) of captive wild mongooses in Okinawa and 3.8% (1/26) of masked palm civets in Chiba Prefectures, respectively. It is suggested that both animal species may serve as a source of infection for cat-scratch disease.
