Abstract

|
In order to observe the endemic status of Clonrchis sinensis infection in Samrangjin eup, Milyang gun, Kyongsang nam do, a total number of 294 stool specimens were collected from the inhabitants who lived in the basin of the Nakdong river. The specimens were examined by cellophane thick smear technique and Stoll´s egg dilution technique during the period from May to June 1983.
The epidemiological status was analyzed statistically by the regression equation and catalytic curv with the results obtained from this area.
The results are as follows
1) The infestation rate of Clonorchis sinensis in 294 was 49.0%.
2) No remarkable difference was observed between male (52.5%) and female (44.8%).
3) Average E.P. G. by Stoll´s egg dilution technique in this area was 9,597.
4) The degree of the intensity of Clonorchis infection by E.P.G. count was distributed as 10.5% in very heavy infection, 14.7% in heavy infection, 47.4% in moderate infection, and 29.3 % in light infection.
5) The intensity of endemicity in this area was represented with the regression equation calculated with the cumulative percentages of E. P. G. counts.
Regression equation was y=3.40+1.23 log x and Cs. D.50 was 19.99.
6) The two stage catalytic model was applied and the calculation lead to the equation y=1.296(e-0 008t-e-035t ) ; a=0.035 > b= 0.008 in this surveyed area.
7) Other helminthic infection rate in this area was 7.1% in A. lumbricoides, 9.5% in T, trichiura and 4.1% in E. vermicularis respectively.
