摘要
在墨西哥的蝙蝠中钩端螺旋体的记录很少。已知几种蝙蝠是致病性钩端螺旋体的宿主。因此,它们参与流行病学周期,并可能产生向人和动物传播的情景。目的是检测在墨西哥Yucatán半岛四个地点捕获的蝙蝠的钩端螺旋体的DNA。从蝙蝠身上收集了一个肾脏碎片,用于提取基因组DNA。采用PCR法检测钩端螺旋体的DNA。对54种蝙蝠进行了研究,包括圆齿蝠、长齿蝠、中美洲翼蝠、黄翅蝠、长尾翼蝠、大翅蝠、黑翅蝠、阿兹特翼蝠、细尾翼蝠、双翼翼蝠和巨叶翼蝠。钩端螺旋体总感染率为44.4% (24/54,95% CI 36.2 ~ 71.7%)。至少有1个阳性个体的种为圆齿棘球绦虫、cozumelae、中美洲棘球绦虫、laticaudatus、macrotis、nigricans、leporinus、aztecus和bilineata棘球绦虫。钩端螺旋体在不同种类的蝙蝠中有较高的传播频率。蝙蝠中钩端螺旋体的存在与公共和动物卫生有关,因为有证据表明它们可以产生人畜共患传播循环。
Detección de Leptospira spp. en murciélagos de la península de Yucatán, México
The records of Leptospira spp. in bats from México are scarce. It is known that several species of bats are hosts of pathogenic Leptospira spp.; therefore, they participate in the epidemiological cycle and can generate transmission scenarios to people and animals. The aim was to detect the DNA of Leptospira spp. in bats captured in four sites from the Yucatán Peninsula, México. A kidney fragment was collected from the bats and used to extract genomic DNA. Using a PCR, the DNA of Leptospira spp. was detected. Fifty–four bats of the species Desmodus rotundus, Mimon cozumelae, Pteronotus mesoamericanus, Pteronotus fulvus, Nyctinomops laticaudatus, Peropteryx macrotis, Molossus nigricans, Molossus aztecus, Noctilio leporinus, Saccopteryx bilineata and Mormoops megalophylla were studied. The PCR yielded a total frequency of Leptospira spp. of 44.4% (24/54, 95% CI 36.2–71.7%). Species with at least one positive individual were D. rotundus, M. cozumelae, P. mesoamericanus, N. laticaudatus, P. macrotis, M. nigricans, N. leporinus, M. aztecus, and S. bilineata. A high frequency of Leptospira spp. was found in different species of bats belonging to several trophic guilds. The presence of Leptospira spp. in bats is relevant for Public and Animal Health because the evidence indicates that they can generate zoonotic transmission cycles.
