Abstract
|
|
|
The distribution pattern of Clonorchis sinensis metacercari in Pseudorasvora parva population and correlation between P. parva and metacercaria of C. sinensis were studied.. The surveyed areas were Chomanpo and Bulamdong, Kim-Hae Gun which were endemic area. of clonorchiasis, and Wansa, Sa-Chon Gun,. Souh Kyong-Sang Do.
The results are as follows
1) The areas of Chomanpo and Wansa showed high infectivity in 99-100% of infection rate and 282-308 of average infection number perfish. But the area of Bulamdong showed relatively. Low infectivity in 95.8% of infection rate and 44 of average infection number.
2) The distribution patterns of C sinensis metacercaria in P. parva population which were collected in Chomanpo and Wansa were shown Poisson distribution and the distribution pattern in Bulamdong showed mid-pattern of shifting over from Poisson distribution to Negative binomial distribution.
3) The correlation between P. parva length and average number of C. sinensis metacercaria in the present studied areas represented as direct proportion relationship.
