  • A rabbit farm reared about 500 New Zealand White in Kwangju city was occurred Eimeria stiedae infection. Morbidity and cumulative mortality were more than 39% and 14%, respectively, from May, 1997 to March, 1998. Most of cases with severe diarrhea were belong to younger than 2-month old. In necrospy, there were multifocally white nodules with about 1-5mm in diameter on the liver surface and dark greenish mucous exudate in intestinal lumen. Main microscopic lesions included marked hyperplasia of the bile duct epitheilia containing different developmental stages of Eimeria stiedae and inflammatory cell infiltration, and the degeneration of small intestinal epithelia. Many oocysts of Eimeria stiedae were detected in the intestinal contents and epithelia, the feces, the bile juice, the bile duct and the liver.

  • Hepatic coccidiosis was occurred in a rabbit farm in Chonbuk province. Clinically, rabbits showed anorexia, diarrhea, dehydration, and depression, subsequently died 3 - 5 days after onset of clinical signs. Grossly, multifocal white spots or lines on the liver suface were observed. Histopathologic lesions included hyperplasia of bile duct epithelium with infiltration of inflammatory cells such as plasma cells and granulocytes, which represents chronic pericholangitis. Different developmental stages of Eimeria stiedae were observed inside the epithelium of biliary system. This is the case of hepatic coccidiosis in rabbits.

  • The aim of this study was to identify antigens for a vaccine or drug target to control rabbit coccidiosis. A combination of 2-dimensional electrophoresis, immunoblotting, and mass spectrometric analysis were used to identify novel antigens from the sporozoites of Eimeria stiedae. Protein spots were recognized by the sera of New Zealand rabbits infected artificially with E. stiedae. The proteins were characterized by matrix-assisted laser desorption ionization time of flight mass spectrometry (MALDI-TOF/TOF-MS) analysis in combination with bioinformatics. Approximately 868 protein spots were detected by silver-staining, and a total of 41 immunoreactive protein spots were recognized by anti-E. stiedae sera. Finally, 23 protein spots were successfully identified. The proteins such as heat shock protein 70 and aspartyl protease may have potential as immunodiagnostic or vaccine antigens. The immunoreactive proteins were found to possess a wide range of biological functions. This study is the first to report the proteins recognized by sera of infected rabbits with E. stiedae, which might be helpful in identifying potential targets for vaccine development to control rabbit coccidiosis.

  • 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.
