An antimicrobial susceptibility test was conducted to compare the resistance rates among Campylobacter spp. isolates from dogs (n = 50) raised under diverse conditions and humans (n = 50). More than 60% of Campylobacter (C.) jejuni from dogs and humans showed resistance to nalidixic acid, enrofloxacin and ciprofloxacin. C. jejuni isolates from humans showed higher resistance to tetracycline (83.3%) and ampicillin (91.3%) than those from dogs. None of the C. jejuni or Campylobacter coli isolates from humans or dogs were resistant to erythromycin. Overall, 85% of Campylobacter spp. isolates showed a multidrug resistant phenotype. Nucleotide sequencing analysis of the gryA gene showed that 100% of NA. /CIP. olates from dogs and humans had the Thr-86. h-Ile mutation, which is associated with fluoroquinolone resistance. flaA PCR restriction fragment length polymorphism (RFLP) typing to differentiate the isolates below the species level revealed 12 different clusters out of 73 strains. The human isolates belonged to eight different RFLP clusters, while five clusters contained dog and human isolates.

Four viruses showing cytopathic effects in MDBK cells were isolated from brains of cattle showing downer cattle syndrome in 2012. The isolates were confirmed to belong to the genus Rubulavirus of the subfamily Paramyxovirinae. Isolate QIA-B1201 had the ability to hemagglutinate red blood cells from several species of animals and was capable of adsorbing guinea pig erythrocytes on the surface of infected Vero cells. Nucleotide sequence analysis showed that two isolates (QIA-B1201 and QIA-B1204) had high similarity with other human and animal PIV5 isolates ranging from 98.1 to 99.8%. The highest sequence similarity of the two isolates corresponded to strain KNU-11 (99.8% at the nucleotide and amino acid level) isolated from suckling piglets in Korea in 2012. To evaluate the virulence of strain QIA-B1201, we inoculated bPIV5 into 5 week-old mice via both the intraperitoneal and intracranial route. Body weight was not significantly altered in mice inoculated with QIA-B1201. In this study, we isolated and characterized novel bPIV5s from brain samples showing downer cattle syndrome, but were not able to elucidate the pathogenicity of the bPIV5s in mice.

Salmonella are causative agents of gastroenteritis and systemic disease in animals. The invA gene was selected as a target sequence of loop-mediated isothermal amplification (LAMP) assay for diagnosis of Salmonella infection. The detection limits for broth dilution, spiked feces and enrichment were 10. 10. and 10. CFUs/mL, respectively. The LAMP assay developed in the present study may be a reliable method for detection of Salmonella spp. in pig feces.

Heo, S.Y., Chonbuk University, Jeonju, Republic of Korea | Kim, N.S., Chonbuk University, Jeonju, Republic of Korea
A 2-year-old male Tosa was admitted for treatment of a non-healing wound on the right forelimb. Skin tests were unremarkable; however, the lesion contained severe proliferative tissue. Surgical treatment was conducted due to the extensive skin defect and granulation tissue present. Following removal of the proliferative tissue, the wound was closed using the adjustable horizontal mattress suture method with multiple punctate relaxing incisions. The proliferative tissue healed completely after the surgical treatment. This technique can be considered an alternative treatment for the proliferative tissue when conditions require a skin graft or flap after surgical treatment.

An 11-year-old castrated male Maltese weighing 3.6 kg and a 12-year-old intact female Shih-tzu weighing 6.5 kg were admitted to the Veterinary Medical Teaching Hospital of Chungnam National University with decompensatory congestive heart failure. Diuretic resistance was suspected due to long term diuretic therapy with furosemide. However, the patients improved after the furosemide treatment was changed to torsemide, demonstrating the benefits of application of torsemide to treat diuretic resistance caused by long term use of furosemide. These findings suggest that torsemide should be applied for treatment of diuretic resistance caused by long term use of furosemide.

A male, 3.5 month old Pomeranian dog was diagnosed with a natural infection of Crenosoma (C.) vulpis in Daejeon, Korea. First stage larvae of C. vulpis were detected by fecal examination using the Baermann technique. Thoracic radiographs revealed mild, pervasive bronchial infiltration of the lung. Enumeration of larvae via the McMaster technique revealed 1,600 larvae per gram of feces. The dog was treated with mebendazole, and clinical symptoms were resolved 2 weeks post-treatment, as indicated by the subject presenting fecal tests negative for C. vulpis.

Jeotgal (salted seafood) has been one of major fermented foods in Korea for long time. Although there are many studies about Jeotgal in various aspects of food, its immunological importance on hosts has not been elucidated yet. In this study, we investigated if several bacteria isolated from Jeotgal may modulate the function of dendritic cells (DCs), powerful antigen-presenting cells equipped with special immunological capabilities. 4 Jeotgal bacteria were selected as representatives and used for experiments. To treat viable DCs, those bacteria were killed at 60¡� for 30 min. The viability of DCs treated with Jeotgal bacteria was verified and two isolates significantly induced high production of interleukin-12, a representative cell-mediated cytokine of DCs. Surface activation and maturation markers (MHC class II, CD40, CD86) of DCs were analyzed by flow cytometer. In addition, the treated DCs showed significantly high lymphocyte stimulatory capability compared to control DCs based on allogeneic mixed lymphocyte reactions. These observations suggest that Jeotgal isolates can function as immunostimulating bacteria in hosts, like Lactobacillus. Taken together, these experimental evidences may broaden the use of Jeotgal isolates in immunological fields in addition to as a fermented food.

An, H.J., Animal and Plant Quarantine Agency, Anyang, Republic of Korea | Kim, C.H., Animal and Plant Quarantine Agency, Anyang, Republic of Korea | Kown, Y.J., Animal and Plant Quarantine Agency, Anyang, Republic of Korea | Kim, D.H., Animal and Plant Quarantine Agency, Anyang, Republic of Korea | Wee, S.H., Animal and Plant Quarantine Agency, Anyang, Republic of Korea | Moo, J.S., Animal and Plant Quarantine Agency, Anyang, Republic of Korea
A nationwide survey on radiation safety management in Korean animal hospitals was conducted. By 2013, 53 radiation generators were registered as veterinary medical devices (41 X-ray generators and 12 computed tomography scanners). Additionally there were six approved laboratories for radiation equipment and protection facility, and five approved laboratories for radiation exposure of employees, respectively. By March 2013, 2,030 out of 3,829 animal hospitals operated radiation-generating devices. Among these devices, 389 (19.2%) out of 2,030 were not labeled with the model name and 746 (36.7%) were not labeled with production dates. Thus, most veterinary X-ray generators were outdated (42.6%) and needed replacements. When periodic inspections of 2,018 animal hospitals were performed after revision of the Veterinarians Act in 2011, the hospitals were found to be equipped with appropriate radiation generators and protection facilities. Among 2,545 employees exposed to radiation at the hospitals, 93.9% were veterinarians, 4.3% were animal nurse technicians, and 18% held other positions. Among 169 employees supervised by administrators, none of those had a weekly maximum operating load that exceeded 10mA min This study suggests that the radiation safety management system of animal hospitals was general good.

Lee, S.H., Chungnam National University, Daejeon, Republic of Korea | Lim, S.J., Chungnam National University, Daejeon, Republic of Korea | Park, H.J., Chungnam National University, Daejeon, Republic of Korea | Song, K.H., Chungnam National University, Daejeon, Republic of Korea
The present study compared leptin, adiponectin, and thyroid hormone concentrations in normal and obese dogs, and evaluated the association between leptin and adiponectin concentrations and thyroid function. The serum leptin, adiponectin, thyroid-stimulating hormone (TSH), total thyroxine (tT4), free thyroxine (fT4), triiodothyronine (T3), and cortisol concentrations were measured in 18 normal dogs (body condition score [BCS]: 4-5/9) and 16 obese dogs (BCS: 8-9/9). Leptin and T3 concentrations were higher in the obese group than the normal weight group (p 0.01 and p 0.05, respectively). In both groups, the T3 and leptin concentrations were correlated (r

In Korea, brucellosis has been reported periodically in cattle and rarely in dogs; however, it has not previously been screened in domestic animals such as elk, pigs and goats. To investigate the serological prevalence, serum samples were taken from the aforementioned animals annually during 2007-2013 and screened by the rose-bengal test (RBT) or modified RBT, after which positive sera were evaluated by the standard tube agglutination test (STAT). Finally, RBT and STAT-positive sera were confirmed by competitive-ELISA. Brucella abortus biovar 1 was isolated from three elk that were shown to be positive serologically in 2008. There was no evidence of brucellosis in pigs. Based on serological monitoring and investigation of etiological agents, there is no evidence of outbreak of brucellosis in elk, pigs or goats of Korea since 2008. However, the possibility for brucellosis from cattle to affect these other livestock exists; therefore, extensive and continuous serological monitoring is required to maintain their brucellosis-free status.
