A weakened wild feral pig (a boar of about 15 kg) with snout distortion and characteristic external lesion of infectious atrophic rhinitis was captured at farm land near low mountains in Chinju, Kyeongnam province. This pig was necropsied and then the snout parts and the parenchymal organs were removed. The snout and nose were transversely sectioned at thickness of 1.5 cm interval. Grossly, the right side of the snout was shorted than that of left by reduction of right nasal turbinate length, but the nasal opening exudate was not observed. At necropsy, degeneration, adhesion, occlusion, and asymmetry of left and right sides on the meatus and turbinate were observed and findings of mild pneumonia were observed. Microscopically, the leukocyte infiltration, hyperemia and hyperplasia on the mucosa of the turbinates and septum were observed. The atrophied periosteum and osseous tissue were also observed. But Bordetella bronchiseptica was not identified in culture from nasal swabs. We expect the possibility that the snout distortion of this pig was due to infectious atrophic rhinitis according to these findings.

This is the first case report of Stephanurus dentatus infection of a feral pig in Korea. In late April, 2000, a weakened feral pig was caught by blow gun from a very low level mountain near the Gyeongsang National University. We autopsied the feral pig in the laboratory of veterinary anatomy at the College of Veterinary Medicine. A total of 27 adult parasites, 11 females and 16 males, and numerous eggs were observed from the cysts formed in the perirenal tissues and ureters. The average size of males was $25.1{\pm}3.2mm$ long and of the females was $34.2{\pm}2.9mm$. The worms were stout, the females being about 2mm broad, and the internal organs were partly visible through the cuticle. The shape of thin-shelled eggs found in the cysts of perirenal tissues and ureter was ellisoidal and oval, and measured $40{\sim}65{\times}90{\sim}115{\mu}m$. The adult parasites were found in cysts which varied from 0.6 to 4cm in diameter, each cyst usually containing a pair of adult worms embedded in green pus. The ureter was thickened and almost occluded, with consequent hydronephrosis.

African swine fever (ASF), caused by the ASF virus, a member of the Asfarviridae family, is one of the most important diseases in the swine industry due to its clinical and economic impacts. Since the first report of ASF a century ago, ample information has become available, but prevention and treatment measures are still inadequate. Two waves of epizootic outbreaks have occurred worldwide. While the first wave of the epizootic outbreak was controlled in most of the infected areas, the second wave is currently active in the European and Asian continents, causing severe economic losses to the pig industry. There are different patterns of spreading in the outbreaks between those in European and Asian countries. Prevention and control of ASF are very difficult due to the lack of available vaccines and effective therapeutic measures. However, recent outbreaks in South Korea have been successfully controlled on swine farms, although feral pigs are periodically being found to be positive for the ASF virus. Therefore, we would like to share our story regarding the preparation and application of control measures. The success in controlling ASF on farms in South Korea is largely due to the awareness and education of swine farmers and practitioners, the early detection of infected animals, the implementation of strict control policies by the government, and widespread sharing of information among stakeholders. Based on the experience gained from the outbreaks in South Korea, this review describes the current understanding of the ASF virus and its pathogenic mechanisms, epidemiology, and control.
