Blood from livestock is a common by-product which is obtained in industrial slaughterhouses. Blood is mainly composed of three fractions, red blood cells (RBCs), white blood cells (WBCs) and plasma. Plasma contains about 8% proteins, which is mainly composed of albumin, globulins and fibrinogen. Hemoglobin is the major protein within whole blood including RBC. These proteins isolated from animal blood have been used in variety of industry such as food, medical, pharmaceutics, animal feed and laboratory. Initially, blood is sterile in healthy animals thus adequate blood collecting system helps to minimize the risk of contamination. In Europe, closed-draining systems are adopted and a high-quality blood product is produced. European Union lays down health rules as regard animal by-products and derived products called Regulation (EC) No 1774/2002 which is improved to No 1069/2009. This regulation lays down strict animal and public health rules for the blood collection, transport, storage, handling, processing and use or disposal of all animal by-products. In spite of the significant using of blood from livestock, almost blood from slaughtering is considered a waste except only small part for use and causes a serious environmental pollution in Korea. Because of the environmental pollution by blood from slaughterhouse, the great expense is loosed, and blood-related products are small and are imported from foreign countries in Korea. For successful blood utilization, suitable infrastructure facilities are needed to control microbial contamination of blood from slaughterhouses and more specific plans on animal blood control may be established at the same time.

The objective of this study was to investigate the effect of a herd specific vaccine against Staphylococcus aureus (S. aureus) by different inoculation route, IMI (intramammary injection), Koso, and supramammary lymphnode area. Based on strains of S. aureus from a case of acute clinical mastitis in Daekwanryeong farm, two experimental vaccines were made, inactivated vaccine and sonicated one. To determine the antigen concentration of the vaccine, 220 ICR-mice were immunized by the intraperitoneal route with inactivated or sonicated experimental vaccines according to different schedules with 10 ICR mice as a control group. The sonicated vaccine was selected for further experiments in vaccination and the highest antibody titer in ELISA was observed at 3㎎/㎖ of the vaccine. The vaccine was administrated to 22 healthy cows at drying up. The quarter milk samples and bloods were collected before vaccination, right after parturition and 3 months postpartum. There were no significant differences among vaccination routes based on the antibody titers in serum and intramammary bacterial infections during drying up period. The antibody titer in serum of vaccinated cows was higher at parturition than 3 months postpartum but it had no statistical meaning, though decreased clinical signs and morbidity were observed. Results of this study suggest that the concept of the vaccine against S. aureus is to decreasing clinical mastitis rather than preventing the disease.

There are many researches about the contribution of virginiamycin use in animals to quinupristin/dalfopristin (Q/D) resistance in humans. In this study, the prevalence and mechanisms of streptogramin resistance in Enterococcus faecium from chickens were investigated. A total of 170 E. faecium isolates from 38 chicken farms was tested for antimicrobial susceptibility. Eleven (6.5%) E. faecium isolates were found to be resistant to Q/D. The vatE and ermB genes were detected in 2 (18%) and 6 (55%) of Q/D-resistant E. faecium respectively. By using pulsed-field gel electrophoresis (PFGE), 6 distinct PFGE patterns were identified. These data indicate that Q/D resistance among E. faecium from chickens remains low despite the long history of virginiamycin use. However, we have to concern over antimicrobial resistance in bacteria originated from animals, including the possibility of transfer of resistance genes from animal to human.

Our previous study demonstrated that fermented four-herb combination (Ulgum, Yagmomil, Maesil and Bokbunja) with probiotics (Saccharomyces cerevisiae, Lactobacillus acidophilus, Bacillus subtilis) (hence, this additives was designated PFH) have immune enhancing and antibacterial effects in broiler chickens. The aims of the present study were to investigate the effects of PFH on growth performance and meat quality of broiler chickens. Twenty-day-old Ross broiler chickens were fed with or without PFH for 2 weeks. Body weight gain of the 2% PFH-fed group was significantly increased compared with those of the control group (*P<0.05). Moreover, body weight gain of the 1% PFH-fed group was also showed a increased tendency compared with the control group, although the difference was not significant (P=0.06). However, no significant difference in feed intake was observed among the groups. Feed conversion ratio of the 2% PFH-fed group was significantly decreased compared with those of the control group (*P <0.05). In addition, feed conversion ratio of the 1% PFH-fed group was also showed a slightly decreased tendency compared with the control group, although the difference was not significant (P=0.07). However, no significant differences in the proximate composition (moisture, crude fat, crude protein and crude ash) and the physico-chemical index (cooking loss, shearing force, water holding capacity and pH) were found among the groups. In addition, succulence, tending and flavor in meat of all 3 groups were also not different. Taken together, these findings suggest the possibility that PFH could be used as the alternative of antibiotic growth promoters by improving the performance of broiler chickens.

Canine parvovirus (CPV) type 2a (CPV-2a) has recently been identified as the main genotype circulating in the dog population in South Korea. Although CPV vaccines protect domestic dogs from CPV-2 infection, the efficacy of commercial live or inactivated CPV vaccines against CPV-2a has not been reevaluated. In this study, dogs were immunized with one of 7 commercial CPV vaccines (4 modified live and 3 inactivated vaccines) followed by challenge with CPV-2a strain, KV0901 that had been isolated from naturally infected dog in 2009. All dogs vaccinated twice with 4 commercial modified live CPV vaccines were seroconverted (geometric mean HI titer > 190.2) and most of dogs were completely protected against virulent CPV-2a strain infection. The dogs inoculated with 3 commercial inactivated CPV vaccines were also seroconverted and showed a slight loss of appetite and light diarrhea for 4 days after challenge and returned to normal at 5 days post challenge. However, the non-vaccinated dogs revealed the typical clinical signs of CPV infection including haemorrhgic diarrhea. In conclusion, the 4 live CPV vaccines licensed in Korea cross-protected dogs against virulent challenge with CPV-2a and are applicalble to pet dogs for the prevention of CPV infection.

To evaluate the performance of a new automated coliform enumeration system (TEMPO® CC) for the quantitative test of coliform bacteria contaminated in domestic livestock processed foods, a total of 507 samples of livestock foods were tested by the TEMPO® CC method, the most probable number (MPN) method, and Petrifilm method, respectively. The results of those three methods were compared to each other. Of 507 samples of livestock processed foods used in this study, 217 samples were contaminated artificially with coliform bacteria and the rest (n=290) were contaminated naturally. The results of the TEMPO® CC method for all samples were equivalent to those obtained from the MPN method, except 8 samples. In addition, 496 (97.8%) out of 507 samples made agreement between the TEMPO® CC method and the Petrifilm method. The correlation coefficients between TEMPO® CC and MPN methods as well as between TEMPO® CC method and Petrifilm method were above 0.9, and the slope and intercept of the linear regression model was different in less than 1 value. In conclusion, there were statistically equivalent levels of performance between the TEMPO® CC and the reference and alternative methods for the enumeration of coliform bacteria in livestock processed foods in this study.

Erysipelothrix rhusiopathiae is a causative agent of erysipelas in avian and mammalian species globally. Eight dead 5-week-old Ross broiler chickens were submitted for diagnostic tests in September 2005. Typical signs including white necrotic foci on the liver, focal congestion of the pancreas, severe atrophy and hardening of the bursa of Fabricius were detected. E. rhusiopathiae was isolated from haemorrhagic lung samples. However, no specific PCR product for the viral diseases tested was detected in these chicken samples. To our best knowledge, this is the first report of the isolation of E. rhusiopathiae in broiler chickens in Korea.

Korea had experienced second epidemic highly pathogenic avian influenza (HPAI), and there were the seven affected farms, including two breeder duck farms, from 22nd November 2006 to 6th March 2007. Here, we reported the clinico-pathological characteristics of domestic breeder ducks farms naturally infected with HPAI virus (H5N1). Clinically, the most ducks showed various signs from depression, decreased egg production and feed consumption to even, death. The most commonly gross changes were hepatomegaly, splenomegaly, petechial and ecchymotic hemorrhage on the liver surface, a white stripe on the cardiac muscle, and severely hemorrhagic and deformed eggs. The most significant histopathological changes were necrosis of various cells such as neuron, lymphocytes, cardiac myocytes, hepatocytes, blood vessels and pancreatic acinar epithelium. The viral antigen was mainly detected in the endothelium of blood vessels of various organs and tissues, peripheral nerves and neuronal cells. Based on the above results, we identified that HPAI H5N1 induced systemic infection in the adult breeder ducks.
