The purpose of this study was to establish a method for in vitro culture of C parvum isolated in Korea by determination of suitable cell model to complete development of this parasite. The result obtained were summerized as follows: 1. To determine the most suitable cell line, six types of cell line were examined by microscopy. All cell lines were infected with C parvum and showed the highest infection score in HmLu cells. 2. The staining methods including DMSO-modified acid-fast(A-F) stain, hematoxylin-eosin(H & E) stain and immunofluorescence antibody(IFA) stain were applied to examine the infection of C parvum in cell culture. These staining methods were possible to examine the infection of C parvum in cell culture. The most sensitive one was IFA staining technique. 3. Developmental stages of C parvum in HmLu cell were observed. After the initial 8 hour incubation period, some trophozoites were observed. The meronts and gametes were appeared at 24-48 hour post inoculation(PI), and oocysts were observed firstly at 48-72 hour PI. 4. In H & E stain, the parasite appeared as basophilic within parasitophorous vacuole membrane(PVM) and lying in cytoplasm at near the nucleus of the host cells. It was able to distinguish the type I, type II meronts and gametes. 5. In DMSO-modified acid-fast stain, specific stained parasites were appeared firstly after 48 hour PI. The parasites were showed with different degrees of staining bright red color within PVM. 6. The endogenous stages of parasites in HmLu cell recovered at 48, 96, 120 and 144 hour after inoculation were reacted with rabbit immunized serum in immunofluorescence antibody and avidin-biotin complex peroxidase staining technique.

This survey was carried out to detect the residual antibiotics in muscles of slaughter cattle from slaughter houses in Seoul from 1991 to 1998 using by EEC-4-plate method. The results were summarized as follows: 1. Residual materials were detected in 402 samples(3.12 %) by EEC-4-plate method. The detection ratios were highest in 1995 (9.51%), autumn (39.8%), Kyeonggi province (54.2%), Holestain(60.4%) and male(50.7%). 2. Residual antibiotics for 18 samples were classified as TCs(72.2%), sulfonamides(38.8%) and β-lactams(5.5 %) by HPLC 3. The residual concentration of oxytetracycline, sulfonamide and 13-lactams were 0.34~ 15.93ppm, 0.17~1.l8ppm and 0.06ppm, respectively.
