Many chemical disinfectants are using to protect the foot and mouth disease (FMD) and avian influenza (AI) in Korea since 2000. This study was performed to confirm disinfective ability of commercialized chemical disinfectants and to investigate the sterilizing ability of E-ball as alterative to chemical disinfectants. 4 kinds of acidulant, 3 kinds of aldehyde, 1 kind of oxidizer and 300 g of E-ball were used in this study. Dilution rate of disinfective power of all chemical disinfectants were to 200 times. The sterilizing ability of aldehydes were better than the acidulant and oxidizer with Salmonella typhimurium. The sterilizing ability of E-ball treated solution was guessed due to the friction of E-ball deads. In the case of the friction of 2 beads of E-ball, Salmonella typhimurium was sterilizted on
CFU in the E-ball treated solution. The E-ball treated solution had superior sterizing power compared with the chemical disinfectants in the bacteria of soil for antibacterial examination. E-ball treated solution has a possibility as the substitute of chemical disinfectants to protective the animal diseases contains FMD, AI.

The bacterium causing Johne's disease (JD), Mycobacterium avium subspecies paratuberculosis (MAP), is distributed worldwide and causes progressive intestinal disease, also known as paratuberculosis, in domestic and exotic ruminants, including cattle. The subclinical form of this disease results in progressive weight loss, reduced milk production, lower slaughter value, and premature culling, with possible impacts on fertility and udder health. Eventually, infection can lead to the clinical form that manifests chronic diarrhea, emaciation, debilitation, and eventual death. JD is a major cause of economic loss in cattle industry. In this study, serological testing was conducted by ELISA to determine the prevalence of MAP in Korean native cattle of Jeju during the duration of 2010 to 2013. A total of 5,150 blood sera were collected in 111 farms and the samples were classified into four different age groups for MAP; group 1 (2 years or less), group 2 (2~4 years), group 3 (5~7 years), and group 4 (over 8 years). Overall seroprevalence of MAP was 5.2% (269/5,150), and annually from 2010 to 2013, they were 11.6% (106/915), 2.1% (10/474), 5.5% (89/1,627), and 3.0% (64/2,134), respectively. Also, the prevalence rates was determined by age groups: 48 of group 1 (17.8%), 154 of group 2 (57.3%), 48 of group 3 (17.8%), and 19 of group 4 (7.1%) were seropositive for MAP. Although seropositive samples were found in all age groups, the highest seroprevalence was found in group 2. This study showed that during the investigation the seroprevalence of MAP tended to decrease.

This study was conducted to investigate the prevalence of fascioliasis in slaughtered cattle in Kangwon (Wonju, Hoengseong, Hongcheon, Cheorwon, Pyeongchang) province and Daejeon from October to December in 2014. From the total 10,780 examined cattle, 0.54% (58/10,780) were found to be positive for fascioliasis by postmortem macroscopic inspection. The Fasciola spp. infection rates were higher in the most Daejeon (1.83%, 41/2,240), followed by Hoengseong (0.40%, 15/3,714) and Hongcheon (0.22%, 2/901). It was not infected in the other regions. The outward appearances of Fasciola spp. infected livers looked almost normal and the worms were all parasitize in the main hepatic duct.

Both Q-fever and Toxoplasmosis are zoonosis. Q-fever occurs due to intracellular bacteria, while Toxoplasmosis is created by protozoan. Both of them have a wide range of host including livestock and wild animals and occur sporadically all over in the world. In this study, seroprevalence of Q-fever and Toxoplasmosis was investigated on cows bred in the area of Seoul where there was a fairly high possibility to occur, while vaccine was not used in Korea. As for experiment materials, cattle blood collected from 190 cows from February to September in 2014 was used ELISA. According to the result, there was a positive reaction on Q-fever from 18 cows out of total 190 cows (9.5%) and on Toxoplasmosis from 32 cows (16.8%). Seroprevalence of both diseases per age was turned out to be negative for those aged less than 2. In addition, it was shown to be positive on 4 cows out of 87 (4.6%) cows aged from 3 to 5, on 7 cows out of 30 cows (23.3%) aged from 6 to 7. Finally, it was shown to be positive on 7 cows out of 17 cows (41.2%) aged 8 or above. Toxoplasmosis was turned out to be positive on 1 cow out of 56 cows (1.8%) aged less than 2, on 6 cows out of 87 cows (6.9%) aged from 3 to 5, on 17 cows out of 30 cows (56.7%) aged from 6 to 7. In addition, it was turned out to be 8 cows out of 17 cows (47.1%) aged 8 or above. Seroprevalence of both diseases was turned out to be higher as age increased. Therefore, it seems that a wide range of investigation on the entire disease spreaders as well as livestock is required since infection of Q-fever and Toxoplasmosis, types of zoonosis, has continuously occurred, and the number of insects, wild animals, and stray animals serving as a role of spreading diseases by changes in seasons and environments has been gradually increasing in Korea.

This study was aimed to investigate factors that affected the status of wearing personal protective equipment (PPE) for handling poultry carcasses with potential exposure to virulent avian infectious agents. A large outbreak of high pathogenic avian influenza (HPAI) occurred in South Korea in 2014. Many public officers participated for euthanizing and handling livestock carcass. However, several safety issues with using PPE were revealed. Therefore, a questionnaire survey was conducted for 340 people who participated euthanasia and carcass disposal in the place where HPAI mainly occurred in 2014. It was found that 31.8% of the respondents had ever taken off their protective equipment during operations because of its inconvenience. The most inconvenient PPE was goggles (54.6%), followed by mask (20.2%), latex gloves (11.6%), shoe covers (5.9%) and protective clothing (5.3%). The main complaints about this individual PPE was unclear sight, damp emitted toward eye, sweating, tearing easily and sweating, respectively. Considering such problems of PPE, new possible directions for improvement of gloves and goggles were suggested. With newly developed rubber coating fabric gloves and conventionally using latex and fabric gloves, H3N2 influenza virus transmission experiment was conducted. Rubber coating fabric gloves showed similar efficiency for blocking virus transmission with latex laboratory gloves and were not easily torn by sharp claws of chicken. In addition, air flow control safety eyewear was suggested to minimize moisture formation. The air flow control system efficiently suppressed moisture formation inside the goggles. Therefore our study will provide more specific directions about new PPE development for safety protection of actual wearers.

Primary renal tumors are uncommon in dogs with prevalence rate of approximately 1%. Renal carcinoma originating from epithelium of proximal convoluted tubules are more likely to be affected to Middle-aged dogs (average age, 8y), males about twice as often as bitches. A 10-year-old, female, German Shepherd dog with history of anorexia, vomitting and hematuria was referred to the Animal Disease Diagnostic Division in Animal and Plant Quarantine Agency. The dog was necropsied and several organs were collected, fixed in 10% phosphate-buffered formalin, embedded in paraffin wax and sectioned for histopathology. Grossly, the kidneys were bilaterally enlarged (
; right). The numerous cysts varying sizes from 3 to 6 cm in diameter were protruding from the surface of both kidney. A large nodule (
) was discovered between cardiac and diaphragmatic lobe in the right lung. Immunohistochemical examination revealed strong positive reaction to cytokeratin and ki-67 in the nuclei of the epithelial tumor cells. But showed negative reactions to vimentin and CD10. Based on the pathological and immunohistochemical examination, we diagnosed as the bilateral renal cystadenocarcinoma in German shepherd dog.

Bull-boxing in South Korea is a form of competitions in which bulls measure their strength with each other in the form of pushing by putting their heads together. Bull-boxing has been admitted after being designated as a play culture by the government because it does not cause great injuries to animals' bodies and has strong positive aspects such as contributing to livestock farmers' leisure activities, encouragement of animal husbandry, and communities' economic development. However, bull-boxing sometimes causes damage to the head and horns due to the heavy bodies. According to the results of examinations of these damage cases, damage that caused irregular shapes of the base of horns was identified in 31.5% of fighting bulls. The damage to horns is thought to have been caused by the great forces of fighting bulls repeatedly imposed to each other's horns during bull-boxing that caused minute fractures leading to damage to the blood vessels inside the horns resulting in the blocking of delivery of nutrients to the horns causing the deformation of the horns into abnormal shapes. Since bulls' bodies are injured during bull-boxing although the injuries are small as bull-boxing is mainly conducted by pushing, animal protection groups regard bull-boxing as cruelty to animals and request to stop bull-boxing. The present study aims to develop animal welfare type headgears that can protect bulls' horns and heads in order to protect fighting bulls during bull-boxing in terms of animal protection and welfare.

We investigated the residues of 6 cephalosporins (cefquinome, cephalexin, cephalonium, cefazolin, ceftiofur, cefuroxime) using LC-MS/MS in raw meat in Seoul. This method involves extraction of the residue from the meat by distilled water and methanol followed by a manual of residue analysis published by the National Institute of Food and Drug Safety Evaluation. The recoveries ranged between 74.71~90.01% in beef, 73.37~101.40% in pork and 70.87~95.53% in chicken, respectively. The limits of detection were 0.0004~0.0563 mg/kg, and the limits of quantification were 0.001~0.169 mg/kg respectively. Residues of cephalosporins which exceeded maximum residue limits (MRL) were not exceed in any of the 287 samples. However, it is necessary to develop multi-method, which includes the active metabolites of ceftiofur.
