摘要
本文报告闽南地区猪刚刺颚口线虫病流行病学。终宿主猪检查790头,感染率为4.7%,感染强度1~16条虫。第2中间宿主鱼类检查12种,阳性3种,即黄鳝Monopterusalbus,乌鳢Ophiocephalusargus和胡子鲶Clariasbatrachus,感染率依次为30%,10%和4.2%,胡子鲶是国内外宿主新纪录。两栖类检查2种,均阴性。转续宿主蛇类检查5种,阳性4种,它们是银环蛇Bungarusmulticinctus、水泡蛇Enhydrisplumbea、渔游蛇Natrispiscator和中国水蛇E·chinensis感染率分别为71.4%,14.3%,12.5%和12.5%,这4种转续宿主均为国内外首次报告。调查结果显示,闽南地区是刚刺颚口线虫病散发性流行区。鳝鱼和银环蛇是传播本病的重要媒介。
The Present study is concerned with a survey of the epidemiology of Gnathostoma hispidum in Minnan district. A total of 790 pig were examined and infective rate of G.hispidum in pig was 4.7%. The intensity was from 1 to 16 worms, the second intermediate host, 12 species of fishes were examined and 3 species of them, namely Monopterus albus, Ophiocephalus argus, and Carias batrachus were found to be naturally infected with the advanced 3rd-stage larvae of G.hispidum, whereas the last species is recorded for the first time as the host in the world.Their infective rates of the larvae in order were 30%,10%and4.2%,respectively. 2 frogs species were examined and the results were all negative for the larva.5 paratenic hosts species were examined and 4 species, Bungarus multicintus, Enhydris plumbea and Natrix piscator, were found be naturally infected with advanced 3rd-stage larvae of G.hispidum. Their infective rates were 71.4%,14. 3%,12.5%and12. 5% respectively.These 4 snakes species are recorded for the first time as the paratenic host from the world. Our investigations results found that in Minnan district, Monopterus albus and Bungarus multicinctus may play a significant role in spreading G.hispidum disease and above area must be regarded as a sporadic epidemic area of G. hispidum.
