Helminth and their ova or protozoan oocysts from fecal samples of cats in Chonju and Dae-jon area were examined from November 1995 to January 1996. Out of the 43 samples, 41(95.4$\%$) were positive and 66(153.49$\%$) were cumulative

Fecal examination for survey of natural prevalence of Balantidium coli was performed on 1080 healthy bred pigs in Korea, and the positive rate was 56.2%. In order to observe if Balantidium coli might be a secondary invader after certain initiation of the intestinal lesions, the piglet groups preinfected with the protozoa experimentally were treated with Salmonella cholerasuis, Trichuris. cold stress, HCI, and immunosuppressive drug respectively, but no relation was found between them. Also the protozoa were not detected from the intestinal lesions spontaneously formed of 107 pigs which were checked in the slaughter house. According to the above results, Balantidium coli is not directly associated with the formation of any lesions in the pig's large intestine.

In order to monitor the parasites, fecal samples were taken from turkey(n=157), helmeted guineafowl(n=149), pheasant(n=190) and duck(n=190) in Chonbuk province. The identification of the parasites were determined by the fecal examination using the fluatation method and microscopical examination. The results were obtained as follows: 1. The detection rate of the parasites from 4 species of poutry was 47.2%(n=324 heads) out of 686 heads. 2. The identification rate was 85.9% in helmeted guineafowl, 63.2% in pheasant, 44.6% in turkey and 3.2% in duck, in order. 3. The mixed infection rate such as single, double, triple and quadrupl was 25.4%(174 heads), 14.1%(97 heads), 7.3%(50 heads) and 0.4%(3 heads), respectively. 4. The parasites isolated were identified as Capillaria spp. in 225 heads, Eimeria spp in 169 heads, Heterakis gallinarum in 116 heads, Ascaridia galli in 16 heads, Hymenolepis spp. in 3 heads and Strongyloides avium in 1 head, in order.

As a series of basic study for the prevention of zoonotic parasites, fecal samples and internal organs of cats in Iri and its vicinity were examined for helminth and their ova or protozoan oocysts from November 1994 to March 1995. The results obtained were summarized as follows; Out of the 133 samples, 101(75.9%) were positive and 135(101.5%) were cumulative positive for parasites. The following were identified in the samples and positive numbers of each species detected were; Toxocara cati, 51;Isospora spp., 27;Spirometra erinacei, 26;Taenia taeniaeformis, 24;Diphyllobothrium latum, 4;and Capillaria spp., 3, respectively. In analyzing the state of infection, 64.9%(61 heads) of all the cats inspected had a single infection, while the rest(excluding the 32 uninfected cats) had mixed infections: 27.6%(26 heads), 6.4%(6 heads) and 1.1%(1 heads) had double, triple, quadruple infections, respectively. From these results, it can be concluded that since the helminth, zoonotic parasites, in Korean autochthonal cats cause not only various disorders, but also can be very harmful to human beings, they are considered to be of great significance to public health.

In order to investigate the internal parasitic infection, fecal samples were collected from weaning pig(n=l23), porker(n=418) and sow(n=121) in 49 sawdust fermentative pigsty of Chonbuk district. The prevalence and identification of internal parasites were determined by the fecal examination using the floatation and/or sedimentation methods and microscopical examination, respectively. The results were obtained as follows; 1. The detection rate of parasite-eggs from 662 fecal samples was 86.6%. 2. The infection rate of parasite-egg 96.4% in porker, 76.9% in sow, 62.6% in weaning pig, in order. 3. In the concern of mixed infection such as single, double triple and quadraple, the rate was 42.3%, 28.7%, 12.2% and 3.3%, respectively. 4. Ten kinds of the detected eggs were isolated from 662 fecal samples. They were classified as Balantidium coli(63.6%), Trichuris suis(24.8%), isospora spp.(23.5%), Oesophangostomum spp.(17.8%), Ascaris suum(11.8%), Hyostrongylus rubidus(2.8%), Strongyloides spp.(1.7%), Gnathostoma spp.(1.5%), Stephanurus dentatus(1.3%) and Metastrongylus spp.(0.7%), in order.
전북지역의 소와 돼지에서 Cryptosporidium sp의 감염실태 조사

Cryposporidium species have a wide host range. These coccidian parasites are found in close association with epithelial cells of many species of animals including man. The gastrointestinal tract is most commonly affected in young ruminants and this parasite is thought to be considerable importance in calf diarrhea complex. Major outbreaks of cryptosporidiosis have been reported in calves, lambs, pigs and others including avian species. Cryptosporidiosis is transmitted by oocysts of Cryptosporidium species. Because cryptosporidiosis is common infection among animals, early literature considered it a zoonosis. Human infections contracted from calves, cats, and horse feces. However, the resrvoir host is longer considered the major source of infection. Mild cases of disease have been reported in farm workers. Immunosuppressed, very young and very old persons should avoid contact with this parasite because it may cause severe diarrhea. In order to detect of Cryptosporidium sp infection from feces of cattle and pigs at Chonbuk Iksan and Kunsan area, sedimentation and modified acid fast stain were applied. The positive rate of Cryptosporidium sp infection from 1,176 of cattle and 267 of pigs were 0.5% and 16.8%, respectively. According to area in Iksan and Kunsan, the positive rates were 0.4% and 0.9% from cattle, and 18.9% and 12.1% from pigs, respectively. In cattle, positive detection rate was 0.6% in milking cows but not in Korean cattle.
