To investigate if non-hematophagous bats play a role in outbreaks of rabies and blue eye disease (LPMV), we studied the seroprevalence against both agents in several species of non-hematophagous bats on the sub-tropical Pacific coast of the state of Colima, Mexico. The survey covered a predominantly agricultural area (disturbed), and an area dominated by semideciduous dry forest (undisturbed). A total of 151 non-hematophagous bats of 16 species were captured from the two areas. Fifty-six (37%) had antirabic antibodies (Ab) while 87 (58%) did not and 8 samples (5%) had to be discarded because of hemolysis. A much lower (P<0.05) prevalence of antirabic Ab was found in bats caught in disturbed areas (22.7%) compared with those from undisturbed areas (51.9%). The presence of antirabic Ab was not related to sex, genera or feeding habits. The higher prevalence found in bats in the undisturbed area may be the result of more frequent interspecies encounters. Of the 108 sera analyzed for antibodies against LPMV, only one was positive (a male Rhogeessa parvula major, captured in the undisturbed area). This suggests that bats in the surveyed localities do not play a role in the epidemiology of LPMV.
为了调查非吸血蝙蝠是否在狂犬病和蓝眼病(拉古纳·佩德雷加尔病毒,LPMV)的疫情爆发中起作用,我们研究了墨西哥科利马州亚热带太平洋沿岸几种非吸血蝙蝠针对这两种病原体的血清阳性率。该调查覆盖了一个以农业为主的地区(受干扰地区)和一个以半落叶干燥森林为主的地区(未受干扰地区)。从这两个地区共捕获了16种151只非吸血蝙蝠。56只(37%)有抗狂犬病抗体(Ab),87只(58%)没有,8个样本(5%)因溶血而不得不丢弃。与未受干扰地区的蝙蝠(51.9%)相比,在受干扰地区捕获的蝙蝠中抗狂犬病Ab的阳性率要低得多(P<0.05)(22.7%)。抗狂犬病Ab的存在与性别、属或食性无关。在未受干扰地区的蝙蝠中发现的较高阳性率可能是种间接触更频繁的结果。在针对LPMV抗体分析的108份血清中,只有一份呈阳性(一只雄性小粗尾蝠,在未受干扰地区捕获)。这表明在所调查地区的蝙蝠在LPMV的流行病学中不起作用。
