光州地方 畜犬의 內部寄生蟲 感染實態와 公共場所의 寄生蟲卵에 의한 土壤汚染 調査 = (A) survey on the prevalence of internal parasitism in dogs and demonstration of helminth eggs and larvae from soil in Kwangju area

국문 초록 (Abstract)

개의 養便 등에 의하여 土壤이 汚染되는 경우가 흔하고 그러한 土壤의 汚染은 公衆衛生上 重要한 意義를 갖는 것이다. 本 論文에서는 먼저 光州地方에서 飼育되고 있는 畜大의 內部寄生蟲 感染實態를 調査하고, 이어서 寄生蟲卵과 幼蟲에 의한 公共場所의 土壤 汚染狀況을 調査하였다.
畜犬의 內部寄生蟲 感染狀況을 보면 總 對象例數의 73.5%가 各種의 寄生蟲에 感染되어 있었는데 家畜病院의 患犬과 集團養犬場의 畜犬들이 比較的 높은 寄生蟲 感染率을 보였다. 寄生蟲 가운데 가장 높은 感染率을 보인 것은 犬蛔蟲(23.7%) 이었다. 개의 年齡과 寄生蟲 汚染의 關係를 보면 콕시디아, 吸蟲類 및 蛔蟲類는 어린 개에서 感染率이 높았고 條蟲類, 鉤蟲類는 成犬에서 感染率이 높았다.
光州一圓의 公共場所에서 採取한 總 608例의 土壤材料 가운데 30例(4.9%)에서 寄生蟲卵이 檢出되었는데, 蒐集場所別로 보면 公園(10.3%)과 步道(7.9%)의 흙에서 比較的 높은 檢出率을 보였다. 그 밖에 公共놀이터나 學校運動場에서는 蟲卵檢出率이 낮거나 전혀 檢出되지 않았다. 한편 檢出된 幼蟲은 大部分 線蟲類이었으며, 主로 公園의 흙에서 檢出되었다.
土壤에서 檢出된 蟲卵의 大部分은 Toxocara spp. 이었고, 특히 步道의 흙에서 이 蟲卵의 높은 檢出率(4.6%) 을 보였다.

The frequent finding of soil contamination by dogs' feces are remarkable, and such soil contamination can be public health problem. On that account, observations were made on the infection rate of common internal parasites in Kwangju dogs during January to March, 1982 in the first part of the present studies. Dogs' feces were collected from veterinary hospitals, houses, intensive dog-rearing places and footpaths.
On the basis of egg couning, of 464 fecal samples, 73.5% were examination positive. And dogs from veterinary hospitals and intensive dog-rearing places have higher rates of infection than others.
Of the parasites detected, Toxocara canis was the most commonly encountered. And ascarids, flukes and coccidia were more prevalent in pups than in mature dogs, whereas hookworms were detected less often in young dogs than in older ones.
There were significant(p<0.01) differences between age categories for all parasites except tapeworms.
In the second part of the present studies, observations were made on the soil contamination in Kwangju public places during April to June, 1982. Soil samples were collected from play areas, school yards, parks and footpaths.
Of 606 sample, 30(4.9%) were positive for nematode ova. 10.3% of soil samples from parks and 7.9% from footpaths were found to contain nematode eggs. Of the helminthes eggs detected, eggs of Toxocara spp. were the most commonly encountered, and mostly from the soil of footpaths. No eggs were recovered from the soil of school yards; the level of soil contamination was low in public areas.
Egg recovery rate of the soil to dogs' feces collected from footpaths was approximately 1:5. And the larvae demonstrated from the soil in the present study were nematode larvae, mainly recovered from parks.
