江西省并殖吸虫的地理分布

本文根据1988—1989年对江西并殖吸虫的调查结果和参照该省并殖吸虫的历史资料,汇总报道江西省并殖吸虫地理分布情况。江西省共有101个县,其中查见并殖吸虫的有45个县、市、区,占44.6％。所查见的并殖吸虫隶属卫氏并殖吸虫、斯氏狸殖吸虫和三平正并殖吸虫。卫氏并殖吸虫分布于45个县、市、区;斯氏狸殖吸虫主要散在分布于罗霄山脉一线;三平正并殖吸虫仅见 于赣东武夷山脉。本省并殖吸虫疫源地或流行区主要分布于海拔200-1000m的各大山脉及其丘陵地带。以海拔400—600m地带的淡水蟹类的并殖吸虫感染率和感染度为最高。如九岭山脉的万载、铜鼓及幕阜山脉的庐山等地的溪蟹卫氏并殖吸虫的感染率高达78.1％-100％;感染度为6.7-221.3个。

GEOGRAPHIC DISTRIBUTION OF PARAGON IMUS IN JIANGXI PROVINCE

Three species of Paragonimus, Paragonimus westermani, Pagumogonimus skrjabint and Euparagonimus cenocopiosus were found in Jiangxi province of China. The do mi- nant species P. westermani was discovered in all 46 counties and cities investigated, however, P. skrjabini mainly found in Luoxiao mountain range and E. conocopiosus only in Wuyi mountain range within the boundaries of the province. These endemic areas were mainly scattered in the mountain regions and hilly lands with elevation of 200- 1000 metres, but between 400- 600 metres the infection rate and intensity of crabs were higher than that below 400 or above 600 metres. It is suggested that the wide distribution of P. westermani should be involved in the variety in its intermediate hosts, paratenic hosts and final hosts, and in the complexity of host transfer.
