|
|
This study was undertaken to evaluate the present status of A. lumbricoides infection in a rural area of Korea.
The 307 residents of all age group in Gu-msa Myun, Yeo Ju Gun were examined by Kato´s cellophane thick smear Asc.aris infection cases by a single dose of 5 mg/kg of body weight.
The whole amount of 24 hour stool during two or three consecutive days were collected separately.
The expelled A. lumbricoides worms from the unfiltered stool remnants were collected.
They were measured by the length and weight, and the sex of the-worms were differentiated.
The results are as follows;
1) The incidence of A..lumbricoids infection of the 307 specimens examined was 40. 1 %(male; 40.9%, female; 39.0%). The difference according to human sex distribution was not statistically significant.
2) Seventy two Ascaris infected cases expelled 163 worms of various size. The mean number of worms per infected case were calculated as 2.3. The sex ratio of examined female and male Ascaris was 1. 5 : 1.
3) Among the expelled 97 female worms, the genital girdls were found in 60 female worms (61.9%) Genital girdle of female worm was located from the head in the position of 38±4 of total legnth 100.
4) The average body length of male Ascaris was 16.3±3. 1cm and female Ascaris was 24.7±3.5cm.
5) The relationship between the weight(Y) and the length (X) of individual Ascaris worm was plotted. Y(gm)=0.32X(cm)-3.1 in female and Y(gm) -= 0.1X(cm) -0. 1 in male.
