  • 소 로타바이러스 설사병은 송아지 특히 생후 2주 이내의 어린 송아지에 심한 물똥설사를 일으키는 바이러스성 질병으로 전염성이 극히 높은 소의 급성 전염병으로 로타바이러스가 원인체이다. 전 세계적으로 널리 발생되고 있으며 우리나라에서도 바이러스성 송아지 설사병 중에서 가장 문제시 되고 있다.

  • Bovine viral diarrhea virus (BVDV) is an important worldwide disease in the livestock industry. To characterize BVDV circulating in Gyeongbuk province in the Republic of Korea which has the highest cattle population density, 365 rectal swabs from clinically BVDV Korean indigenous calves were collected. Fifty cases were identified as positive for BVDV. A phylogenetic analysis of 5'- untranslated regions (UTR) revealed that most of our cases belonged to BVDV-2a (n = 48), while only two cases were classified as BVDV-1a (n = 1) and 1b (n = 1), respectively. These results indicated that BVDV-2a is the most prevalent subgroup in Korean indigenous calves of Gyeongbuk province.

  • Bovine viral diarrhea virus (BVDV) is an economically important worldwide disease in livestock industry. In this study, the occurrence of BVDV in Korean indigenous cattle was performed by RT-PCR using nasal swab. Twelve of 21 cattle were identified as BVDV positive and classified as persistently infected (PI). These animals showed the occurrence of diseases such as diarrhea and pneumonia. BVDV PI outbreaks were found mostly in PI calves. Sequencing and phylogenetic analysis based on the 5'-untranslated region (UTR) showed that our case belonged to BVDV-2a. These results suggested that the nasal swab sampling was available method for the detection of PI animals, underscoring the need for BVDV control strategies in Korean indigenous cattle.

  • A 25-day-old, Korean indigenous calf was presented with a 10 days history of respiratory disorders and bloody diarrhea, and died. This calf was extremely unthrifty compared to others and had evidence of chronic diarrhea based on matting of feces in the hair of the tail and perineum. Ecchymotic hemorrhages were observed on multiple organs at necropsy. Bovine viral diarrhea virus (BVDV) infection was identified by RT-PCR. The phylogenetic analysis showed that this case belonged to BVDV-2a subgroup and was related to highly pathogenic USA isolate 890 (U18059). This case provided evidence for circulation of BVDV-2 in Republic of Korea. The occurrence of BVDV-2 was also reconfirmed.

  • The prevalence of bovine viral diarrhea virus (BVDV) in Korean indigenous calves with diarrhea in Gyeongbuk province was investigated. Seventy-five cases were identified as BVDV positive in the diarrhea stools. Phylogenetic analysis revealed that all our cases were classified as BVDV-2a. Most of the present BVDV-2a cases were isolated from calves showing clinical signs of watery diarrhea. Our observations indicate that not all BVDV-2 infections cause clinically severe disease. This study shows the high incidence of BVDV-2 infection in Gyeongbuk province. Therefore, the results suggest that a vaccine development and immunization strategies are required for the effective control of BVDV infection in the Republic of Korea.

  • Phylogenetic and nucleotide analysis revealed that severe acute bovine viral diarrhea virus (BVDV) outbreaks from Korean indigenous calves belonged to BVDV-2a, and were identical to those of the highly pathogenic BVDV-2 strain 890, with identical virulence markers and classified as highly virulent. These outbreaks affected young calves (20 and 40 day-old) and were characterized by hemorrhagic diarrhea, depression, anorexia, and weakness. The identification of the highly virulent BVDV-2 isolates among Korean indigenous calves may have important implications for epidemiological studies, diagnostic and immunization strategies.

  • A noncytopathic bovine viral diarrhea virus(NC BVDV) strain isolated and purified from persistently infected primary bovine fetal lung(BFL) cells was studied by biophysical methods. The buoyant density of particles of the NC BVDV strain was shown to be between 1,090 and $1,114g/cm^3$ and the maximum virus infectivity occured at $1,098g/cm^3$. Immunoelectron microscopic examination by using the partially purified virus revealed regular spherical particles 30~80nm in diameter. Differences in the genomic size of cytopathic and noncytopathic BVDV from infected cells were not found. A comparison of viral proteins of a noncytopathic and cytopathic strain(NADL) by immunoprecipitation using monoclonal antibody indicated that NC BVDV, compared to cytopathic NADL, was cell associated.
