This study was carried out to investigate the tick-borne pathogens from one hundred nineteen cattle farms (38 farms of Andong, 41 of Yeongju, 12 of Uiseong, 5 of Cheongsong, 5 of Yoengyang, 18 of Bonghwa) in northern areas of Gyeongbuk province by polymerase chain reaction (PCR). Among 119 cattle farms, the positive ratios against Babesia, Theileria, Anaplasma, Ehrlichia and Rickettsia were 3.4% (4/119), 10.1% (12/119), 6.7% (8/119), 1.7% (2/119) and 16.8% (20/119), respectively. Also, the PCR results revealed that 8 farms were positive for T. sergenti in positive of Theileria and 2 farms were positive for A. phagocytophilum in positive of Anaplasma. Therefore, further studies regarding vectors, environmental condition, interaction between domestic and wild animals and development of control program are needed to reduce the numbers of bovine tick-borne disease in northern areas of Gyeongbuk province.

The result of studying the pathogenicity of Salmonella typhimurium and S enteritidis isolated from domestic animals in Gyeongbuk province were summarized as follows. In Congo-red binding test, S typhimurium had much more rough types than S enteritidis. In colicin production test, 4 strains of S typhimurium were positive but all of S enteritidis were negative. In hemolysin production test, all of S typhimurium and S enteritidis were negative. In Guinea pig serum resistant test, all of S typhimurium and S enteritidis were positive. As a result of pathogenicity test to mice, 54.4% of mice were died. Therefore, S typhimurium and S enteritidis were considered as highly pathogenic. S typhimurium DT104 and S enteritidis PT4 were more pathogenic to mice than other phage types of same serovar. S typhimurium and S enteritidis were considered not so pathogenic for 6-day-old chickens. The recovery rates of Salmonella stains from mice and chickens inoculated were 96.8%, and 54%, respectively. In chickens, proportional to the time from 2 weeks after challenge inoculation, the recovery rates were noticeably decreased.

Brucella (B.) abortus is a facultative intracellular pathogen that infects a wide variety of animal species and human. Brucellosis is the zoonosis and an extremely important disease around the world. Although the eight species can be differentiated by conventional phenotypic tests, these species display a high degree of DNA homology in DNA-DNA hybridization assay (>90%). Various methods have been established for genotyping of Brucella species, but most of analytical methods are lack reproducibility and limited capability to differentiate them. The attempt of this study was to evaluate multiple-locus VNTR analysis (MLVA) for use of epidemiological trace-back analysis in bovine brucellosis. Ninety-four B. abortus isolates from Gyeongbuk province during 2006~2010 were analyzed using 16 VNTR locus. High resolution automatic capillary electrophoresis system was used for more throughput, simpleer, faster, and better discriminable than conventional gel electrophoresis. As a result, 13 different genotypes were identified from 94 B. abortus isolates. MLVA could contribute to epidemiological trace-back analysis of bovine brucellosis.

This study was carried out to analyze of the cause of button mushroom production decrease of Gyoengbuk province. In 1978, Agaricus bisporus was produced 48,000 ton and exported more than $50 millions. But since 2000, Domestic production of button mushroom was decreased by 70%, and button mushroom farm was also decreased by 37%. Cultivation area was increased by 6%, but Gyeongbuk Province was decreased by 30%. Especially, Production per $3.3{\ss}{\breve{S}}$ was dramatically decreased more than half. There were several causes such as rising labor and material cost, climate changes, and aging of mushroom cultivation farmers. And there was no effort to develop of domestic button mushroom cultivation equipments. One of the main reasons for this reduction was supplied to low quality of button mushroom compost to the farm.

This study was conducted to investigate antibiotic resistance among Salmonella Typhimurium isolates from diseased pigs in Gyeongbuk province during the period 1998~2011. One hundred forty one isolates were tested for antibiotic resistance using the standard disk diffusion method and were examined for presence of resistance gene by PCR method. S. Typhimurium showed high drug resistance rates to tetracycline (95.7%), streptomycin (93.6%), ampicillin (86.5%), cephalothin (80.1%), gentamicin (79.4%), and trimethoprim/sulfamethoxazole (72.3%). Resistance gene, blaTEM, blaPSE1, tetA, tetB, tetG, sul1, sul2, aadA, strA, grm, and temA were detected among the antibiotic resistance isolates and temB, tetC, aadB gene were not detected. One hundred twenty one (89.6%) tetA, two (1.5%) tetB and one (0.7%) tetG gene were detected in the 135 tetracycline resistant isolates. Two (1.6%) temA gene were detected in one hundred twenty two ampicillin resistance isolates and temB was not detected.

Bovine brucellosis is a zoonosis, long incubation period and chronic infectious disease, usually caused by Brucella abortus. This study was carried out to investigate the biotyping and biochemical characterization of B. abortus isolated from 208 farm 871 korean cattle and holstein diagnosed brucellosis by serological positive in Gyeongbuk province during the period from 2002 to 2006. B. abortus was isolated from 124 (14.2%) of 871 cattle, and isolated 110 (13.4%) of 820 Korean cattle and 14 (27.5%) of 51 holstein in breed. The uterus of korean cattle was isolated in 8 (17.8%) of 45 cattle and supramammary lymph none of holstein was isolated 11 (68.8%) of 16 cattle. 101 (12.5%) of 810 serological positive blood samples were isolated B. abortus. The isolation rate of B. abortus was correlated with antibody titers. The biochemical characterization of isolates was non-hemolytic, production of H$_2$S, oxidase-positive, catalase-positive, hydrolyzation of urea and growth of basic fuchsin dye medium. As a result, all of isolates was identified B. abortus bv 1. 124 isolates were susceptible to ampicillin, lincospectin, amikacin, gentamicin, kanamycin, neomycin, streptomycin, tetracycline, ciprofloxacin, norfloxacin and enrofloxacin.

This study aims to assess an effectiveness of the revitalization policy of traditional market which has been put in force since the late 1990's through a case study of Gyeongbuk province in Korea. According to a qualitative assessment of the improvement project of market facilities and the modernization project of marketing technique, each project has little effect. This seems to be caused by the existing revitalization policy without full considerations of reinforcing the spatial competitiveness of traditional markets. This study suggests an alternative of the revitalization policy of traditional markets concentrating on the spatial competitiveness of them.
