This study was conducted to investigate the species-specific gene detection, capsular serogroup and antimicrobial resistance pattern of Pasteurella multocida isolated from pneumonic lung lesion of swine in Gyeongbuk province. P. multocida isolates were typed for capsular serogroups by polymerase chain reaction. Of the 32 strains, 28 (87.5%) were typed serotype A, 3 (9.3%) were typed serotype D, and 1 strain was unknown (3.1%), respectively. In antimicrobial agents resistance test, almost of strains were susceptible to amoxicillin (100%), enrofloxacin (96.9%), ampicillin (93.8%), florfenicol (90.6%), chloramphenicol (90.6%) and were resistant to streptomycin (71.9%), spectinomycin (56.3%). All strains were resistant to clindamycin, erythromycin and lincomycin.

Q fever is a zoonotic disease caused by the obligate intracellular bacterium Coxiella (C.) burnetii and affects wild and domestic animals worldwide. The aim of this study was to evaluate the seroprevalence of C. burnetii in native Korean goat (Capra hircus coreanae) in Gyeongbuk province, Korea, using ELISA. A total of 256 goat blood samples from 56 farms in Gyeongbuk province were collected between May 2012 and March 2013. Among them, 22 (8.6%) samples from 10 (17.9%) farms were seropositive for C. burnetii by ELISA. According to regional analysis, the seroprevalences among goat farms in eastern, western, southern, and northern areas of Gyeongbuk province were 0%, 18.2%, 36.8%, and 6.3%, respectively, showing the highest seroprevalence in the southern region. Among 22 counties in Gyeongbuk province, 10 (45.5%) counties had one or more farms positive to C. burnetii antibody. Accordingly, the seroprevalence of C. burnetii in high-risk humans and animals are constantly demanded by regional investigation.

Sorbic acid and potassium sorbate are widely used food additives with high efficiancy and they are approved and recommended by FAO and WHO. Sorbic acid is one of preservatives that is mostly used in general food. Sorbic acid and potassium sorbate are used to prevent food, such as cheese, bread, beverage, and so on, from staling and molding. The world market for sorbic acid and potassium sorbate is growing and the market in Asian region is also expected to grow rapidly. This study was carried out to measure the amount of the sorbic acid in cooked meat produced from meat processing plants in Gyeongbuk province during 2000∼2003. One thousand one hundred and thirty-five samples of cooked meat(430 spices added meats, 486 grinding cooked meats, 3 bacons, 23 jerked meats, 68 sausages, 125 hams) were collected from meat processing plants and analyzed for the concentration of preservative sorbic acid by using of high performance liquid chromatography(HPLC). Sorbic acid was not detected in spices added meats, grinding cooked meats and bacons, except on jerked meats, ham and sausage. But the concentration range of sorbic acid in jerked meat was 0.00∼1.5g/kg, average 0.37g/kg, and in sausage was 0.00∼1.31g/kg, average 0.53g/kg, and in ham was 0.00∼ 1.22g/kg, average 0.56g/kg. There was no sample that sorbate concentration exceeded the legal permitted level 2.0g/kg in cooked meat.

This study was performed to determine the prevalence of Theileria sergenti (T. sergenti) in cattle reared in eastern areas of Gyeongbuk province by PCR. Among 443 samples collected from 42 cattle farms, 96 (21.7%) samples from 13 (31.0%) farms were positive for T. sergenti. By regions, 87 (26.6%) out of 327 cattle in Gyeongju, 8 (9.5%) out of 84 cattle in Pohang, and 1 (3.1%) out of 32 cattle in Ulleung were positive for T. sergenti. T. sergenti infection in dairy cattle (27.9%) was significantly higher than that in Korean cattle (9.4%, P<0.0001). Accordingly, Korean cattle were more resistant to T. sergenti infection. Prevalence of T. sergenti in cattle was increased with age (P<0.0001). The infection rate in cows (23.3%) was significantly higher than that in bulls (5.0%, P<0.01). Seasonally, prevalence of T. sergenti in cattle was highest in autumn (32.7%, P<0.01). Prevalence of T. sergenti in grazing cattle (66.7%) was significantly higher than that in non-grazing cattle (15.8%, P<0.0001). Since prevalence of T. sergenti infection is high in cattle reared in eastern areas of Gyeongbuk province, survey on other hemoparasites and appropriate control programs need to be established in this region.

The purpose of this study was to survey seroprevalence of porcine reproductive and respiratory syndrome (PRRS) virus and porcine circovirus-2 (PCV-2) in Gyeongbuk province by enzyme-linked immunosorbent assay (ELISA). A total of 966 samples collected from 21 pig farms were tested. The sero-positive rate of PRRS and PCV-2 were 77.6% (750/966) and 76.4% (738/966), respectively.

For examination of antibiotic therapeutic efficacy in canine brucellosis, this examination was carried out two female bitches infected with Brucella canis in Gyeongbuk province, and used combicillin, baytril and doxycycline in susceptible antibiotics at B canis. During 18 month after the termination of antibiotic therapy, blood sample of the two bitches were examined for B canis antibody and antigen. The antibody of one bitch was disappeared at 5 month after antibiotic therapy and the other was continued at 18 month, but two bitches were not detected antigen by blood culture and PCR. Examination of blood chemical value (AST, ALT, urea, creatinine) of two bitches was increased in AST value during antibiotic therapy.

The Thoroughbred horse was an approximately 4-years-old castrated male with highly emaciation, nasal epistaxis and subsequently died. Gross necropsy revealed epistaxis and hyperemia on the lung, multiple hemorrhage in muscle, and liver was focally attached to the peritoneum with fibrin. According to polymerase chain reaction (PCR), Equine herpes virus type 1 and 4 (EHV type 1, 4) was detected in the lung and trachea. In bacterial culture from kidney, liver, spleen, muscle and blood, Streptococcus equi subsp. zooepidemicus was isolated. Based on the gross lesion and PCR, this horse was diagnosed as EHV type 1, 4 and S. zooepidemicus coinfection.
