In Latin America, rabies cases related to frugivorous bats have been reported since 1930's. Recently, two viruses isolated from Artibeus lituratus were proved to be vampire bat variants by monoclonal antibodies panels [2], but their genetic information is not well known. In this report, four rabies viruses were isolated from frugivorous bats (Artibeus spp.) in Brazil and their nucleoprotein gene sequences were determined. These isolates were found to be genotype 1 of lyssavirus and showed the maximum nucleotide sequence homology of 97.6-99.4% with vampire bat-related viruses in Brazil [6]. These results indicate that the Brazilian frugivorous bat rabies viruses in this study are closely related to vampire bat-related viruses that play a main role in rabies virus transmission to livestock in Brazil.
自20世纪30年代以来,拉丁美洲就已报告了与食果蝙蝠相关的狂犬病病例。最近,通过单克隆抗体鉴定,从白喉叶鼻蝠中分离出的两种病毒被证实为吸血蝙蝠变种[2],但其基因信息尚不明确。在本报告中,从巴西的食果蝙蝠(叶鼻蝠属)中分离出4株狂犬病病毒,并测定了它们的核蛋白基因序列。这些分离株被鉴定为狂犬病病毒1型,与巴西吸血蝙蝠相关病毒的核苷酸序列同源性最高达97.6% - 99.4%[6]。这些结果表明,本研究中的巴西食果蝙蝠狂犬病病毒与吸血蝙蝠相关病毒密切相关,而吸血蝙蝠相关病毒在巴西狂犬病病毒向家畜的传播中起主要作用。
