绍兴兰亭二倍体卫氏并殖吸虫致病性的分析

ANALYSIS ON PATHOGENICITY OF PARAGONIMUS WESTERMANI WITH DIPLOID FORM IN LANTING OF SHAOXING COUNTY,ZHEJIANG PROVINCE

绍兴兰亭自应元岳（１９３０）发现肺吸虫病以来，不少学者对该地并殖吸虫病流行病学进行了研究［１－４］。１９５０年前，人民生活贫困，并殖吸虫病日趋流行严重，溪蟹并殖吸虫囊蚴感染率由７．４％—２７％（４／５４—３１／１１４）（Ｖｏｇｅｌ，１９３４）上升为３...

Abstract The pathogenicity of Paragonimus westermani with diploid form of chromosome was analysed on the basis of review of epidemiological data in Lanting of Shaoxing County from 1934 to 1982. P. westermani infected persons showed typical manifestations of paragonimiasis when the prevalence was high, while signs and symptoms turned to atypical when the prevalence was low. Whether P. westermani with diploid form would contribute to typical manifestations of paragonimiasis might be related to the frequency, number, and way of eating Sinopotamon crabs; the infection rate and intensity of Paragonimus metacercaria in the consumed crabs would also play a role in clinical manifestations.
