Ha Jung Roh, Haan Woo Sung, Hyuk Moo Kwon 대한수의학회 Journal of Veterinary Science 8 Pages
대한수의학회 Journal of Veterinary Science 2006, 제 7권 제 4호 10 361-368 (8 pages)
This study examined the adjuvant effects of dimethyl dioctadecyl ammonium bromide (DDA), CpG oligodeoxynucleotides (CpG-ODN), and chicken interferon-γ (ChIFN-γ) on a DNA vaccine (pcDNA-VP243) against the infectious bursal disease virus (IBDV). A plasmid encoding chicken IFN-a was constructed. Twice at 2-week intervals, twoweek- old chickens were injected intramuscularly and intraperitoneally with either a DNA vaccine alone or a DNA vaccine together with the respective adjuvants. On week 2... -

대한수의학회 Journal of Veterinary Science 2006, 제 7권 제 3호 6 241-247 (7 pages)
The ability of a heat-inactivated whole virus from a highly virulent infectious bursal disease virus (hvIBDV) and VP2 protein from hvIBDV expressed in E. coli provided protection against a hvIBDV challenge in specificpathogen- free (SPF) chickens. Six out of seven chickens that were injected three times with crude VP2 protein developed significant antibody titer against IBDV. However, only four out of the seven chickens survived the hvIBDV challenge. Despite showing low antibody titer profiles,... -

We have previously described the development of a onetube SYBR Green real-time RT-PCR assay for the detection and quantitation of infectious salmon anemia virus (ISAV) in various biological samples. The twofold aim of the present study was to verify that the optimized SYBR Green real-time RT-PCR conditions could detect ISAV isolates of different geographic origins, and to analyze the growth patterns of the selected ISAV isolates in the Chinook head salmon embryo (CHSE) -214 cells by this assay... -

the sequences from Genbank database and used for identifying antigenic determinants. One of the synthesized thirteen peptides gave strong positive reactivity with most of the sera from 13 FMD infected farms, but not with sera from vaccinated and non-infected animals. Moreover, with the sera collected through serial bleedings from four cattle and five goats infected with FMDV O/SKR/2000 experimentally, positive results were obtained in two species after 10 days post infection (DPI). Therefore, we... -
Immunogenicity of baculovirus expressed recombinant proteins of Japanese encephalitis virus in mice

Genes encoding for the premembrane and envelope (prME), envelope (E) and nonstructural protein (NS1) of Japanese encephalitis virus (JEV) were cloned. Each protein was expressed in baculovirus expression system. Of the three proteins expressed in baculovirus system, only prME had hemagglutination activity. The prME (72 and 54 kDa), E (54 kDa) and NS1 (46 kDa) proteins could be detected by Western blotting in the recombinant virus infected cells. Immunogenicity of the recombinant proteins... -
Application of biotechnological tools for coccidia vaccine development
Wongi Min, Rami A. Dalloul, Hyun S. Lillehoj 대한수의학회 Journal of Veterinary Science 10 Pages
대한수의학회 Journal of Veterinary Science 2004, 제 5권 제 4호 1 279-288 (10 pages)
Coccidiosis is a ubiquitous intestinal protozoan infection of poultry seriously impairing the growth and feed utilization of infected animals. Conventional disease control strategies have relied on prophylactic medication. Due to the continual emergence of drug resistant parasites in the field and increasing incidence of broiler condemnations due to coccidia, novel approaches are urgently needed to reduce economic losses. Understanding the basic biology of host-parasite interactions and... -
Mucosal mast cell-derived chondroitin sulphate levels in and worm expulsion from FcRγ-knockout mice following oral challenge with Strongyloides venezuelensis
Denis Nnabuike Onah, Yukifumi Nawa 대한수의학회 Journal of Veterinary Science 6 Pages
대한수의학회 Journal of Veterinary Science 2004, 제 5권 제 3호 6 221-226 (6 pages)
Mucosal mast cell-derived chondroitin sulphates (sulphated proteoglycans) were assayed in gut washings and homogenate of FcRγ-knockout (KO) and wild-type (WT) C57BL/6 mice challenged with Strongyloides venezuelensis in order to assess their possible role in secondary immunity against enteric nematodes. Groups of immune KO and WT mice were challenged by oral gavage with 300 infective larvae (L3 ). Establishment of infection was assessed by daily faecal analysis to determine the number of eggs... -
Molecular characterization of full-length genome of Japanese encephalitis virus (KV1899) isolated from pigs in Korea
Dong Kun Yang, Byoung Han Kim, Chang Hee Kweon, Jun Hun Kwon, Seong In Lim, Hong Ryul Han 대한수의학회 Journal of Veterinary Science 9 Pages
대한수의학회 Journal of Veterinary Science 2004, 제 5권 제 3호 3 197-205 (9 pages)
We have determined the complete nucleotide and deduced amino acid sequences of the Japanese encephalitis virus (JEV) strain KV1899, isolated from a fattening pig in Korea. In comparison with 22 fully sequenced JEV genomes currently available, we found that the 10,963- nucleotide RNA genome of KV1899 has a 13-nucelotide deletion in the 3' non-translated variable region and 53 unique nucleotide sequences including 3' non-translated region (NTR). Its single open reading frame has a total of 28... -

대한수의학회 Journal of Veterinary Science 2004, 제 5권 제 1호 7 49-58 (10 pages)
Studies were performed to determine the effects of Bcell suppression on the pathogenesis of Subgroup J avian leukosis virus (ALV-J) in broiler chickens. Neonatal chickens were treated with cyclophosphamide (CY) or PBS, and then infected with ALV-J (ADOL-7501) at 2 weeks of age. CY treatment induced B cell specific immunosuppression throughout the experiment confirmed by decreased bursal weight, intact lymphocyte mitogenetic activity stimulated by Con A and increased relative subpopulation of... -

In this study, we investigated the effects of T-cell suppression on the pathogenesis of subgroup J avian leukosis virus (ALV-J). Chickens were treated with cyclosporin A (CSP) 50 mg/Kg body weight or a corresponding volume of olive oil per every three days after hatching until the end of experiment. Some of the chickens from each treatment group were infected with an isolate of ALV-J, ADOL-7501, at 2 weeks of age. The effects of viral infection were compared to uninfected birds in same treatment...
