A preliminary survey for classification of coccidia isolated from domestic animals and poultry was broadly conducted by the morphological aspects of the $o{\ddot{o}}cysts$. The number of animals and birds used in this survey were 762 chickens, 30 rabbits, 37 goats, 18 swine, 39 cattle, 8 dogs, 132 ducks, 23 deer and 15 horses. The species classified in each animal and bird were six species in chicken, nine in rabbits, nine in goats, six in swine, six in cattle, one in dogs and negative in ducks, deer and horses. The coccidial species in each animal and bird were as follows: In chicken: Eimeria acervulina, E.maxima, E. mitis, E. necatrix, E. praecox, and E. tenella. In rabbits: Eimeria irresidua, E. magna, E. media, E. neolepolis, E. perforans, E. piriformis and E. stiedae. In goats: Eimeria ahsata, E. arloingi, E. crandalis, E. faurei, E. granulosa, E. intricata, E. ninakohlyakimovae, E. pallida, E. perva. In Swine: Eimeria deblieki, E. perminuta, E. palita, E. scabra, E. scrofae and Isospora suis. In Cattle : Eimeria bovis, E. bukidonensis, E. cylindrica, E ellipsoidalis, E subspherica and E. Zurnii. In dogs: Isospora bigemina.

I suis cocciosis in piglets seems to occur in the majority of Korean sow herds. Cocci야osis is characterized by a pasty diarrhea in piglets appearing at 5 to 11 days old. Morbidity is variable, Mortality is usually low but piglets growth is always retarded. And, the principal source of infection is the environment because of the high resistance of oocysts. Control of coccidiosis is usually frustrated since the majority of treatment have not constant results. Mundt et al(1990) developed a new strategy by administrating toltrazuril as an oral suspension. This new anticoccidial drug reduced clinical signs and mortality. Therefore, we will try to medicate piglets with Baycox(Bay Vi 9142) suspension in a sow herd, having a problem of I suis coccidiosis. The incidences of coccidiosis in suckling piglets in C and D bleeding stock farm were from 28.6 to 42.3 and 21.1~57.9 % during 3 to 21 day-old. The body weights of suckling piglets in treated groups were higher than those of control groups at 11 and 18 day-old. Also, those of C breeding stock firm were higher than those of D farm. The body weight gains of suckling piglet of treated groups were higher than those of control groups. Also, those of C breeding stock firm were higher than those of D farm. There was no dead piglet in all experimental groups. Some atrophic piglets were done away with. In C breeding stock farm, the incidences of diarrhea in treatment groups were significantly lower an those of control groups. Also, the degrees of diarrhea in treated groups were significantly lower than those in control groups. In D breeding stock farm, the incidences of diarrhea in treated groups were a little lower than those in control groups. Also the degrees of diarrhea in treated groups were a little lower than those in control groups. In the treated groups, the incidences and degrees of diarrhea were reduced at the 4th day and increased at the 13th day after treatment. The number of litters excreted oocysts in treated groups wert lower than those in control groups after treatment. Also, the OPG in treated groups were lower than those in control groups. According to above results, the effect of Baycox suspension against swine coccidiosis was very good. If we will treat with Barcox suspension swine coccidiosis in swine stock farms, we can get good effects of the improvement of body weight gains and diarrhea and e reduce of excreted costs in faeces.

Intestinal infections are common in growing pigs and can be caused by multiple pathogens, environmental and management factors [1]. Among the most important viruses in swine enteritis are porcine epidemic diarrhea virus (PEDV), transmissible gastroenteritis virus (TGEV), porcine enteric calicivirus (PECV), porcine group A rotavirus (PRV gp A) and bacteria are Escherichia coli and Salmonella spp. and protozoa is Isospora suis [1]. The DNA chip system can serve as a powerful tool that can be utilized for simultaneous detection of specific pathogenic bacteria strains and viruses [2,3]. The combination of PCR and DNA chip technology will provide a novel method for the detection of porcine enteric pathogens thus revolutionize the diagnosis and management of the disease. The aim of this study is to develop DNA chip system for the rapid and reliable detection of five major porcine enteric pathogens based on oligonucleotide DNA chip hybridization. (omitted)

In order to investigate the internal parasitic infection, fecal samples were collected from weaning pig(n=123), 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 mired 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%), Oesoohangostomum spp.(17.8%), Ascaris suum(11.8%), Hyostronylus rubiddus (2.8%), strongyloides spp. (1.7%), Gnathostoma spp. (1.5%), Stephanurus dentatus(1.3%) and Metastrongylus spp. (0.7%), in order.
