Yun, S., Seoul National University, Seoul, Republic of Korea | Lee, Y.R., Seoul National University, Seoul, Republic of Korea | Giri, S.S., Seoul National University, Seoul, Republic of Korea | Kim, H.J., Seoul National University, Seoul, Republic of Korea | Chi, C., Seoul National University, Seoul, Republic of Korea | Kim, S.G., Seoul National University, Seoul, Republic of Korea | Kim, S.W., Seoul National University, Seoul, Republic of Korea | Jun, J.W., Seoul National University, Seoul, Republic of Korea | Park, S.C., Seoul National University, Seoul, Republic of Korea
In the present study, Aeromonas (A.) hydrophila was isolated from a captive-bred adult freshwater stingray (Potamotrygon motoro) reared at a commercial aquarium in Korea. The stingray had bites on its fins, hemorrhages on the ventral part, and congested internal organs. A bacterium was isolated from kidney and subsequently identified as A. hydrophila. Based on phylogenetic analysis results, the isolate in the present study (SNUAh-LA1) was most closely related to A. hydrophila AH10 (China) and A. hydrophila AKR1 (Korea). It is most likely that the pathogen infection resulted from Potamotrygon motoro cohabiting with ricefish (Oryzias latipes).

Lee, J., Kangwon National University, Chuncheon, Republic of Korea | Shin, H., Kangwon National University, Chuncheon, Republic of Korea | Lee, W., Biolight Corporation, Seoul, Republic of Korea | Lee, S.T., Kangwon National University, Chuncheon, Republic of Korea | Lee, G.S., Kangwon National University, Chuncheon, Republic of Korea | Hyun, S.H., Chungbuk National University, Cheongju, Republic of Korea | Lee, E., Kangwon National University, Chuncheon, Republic of Korea
This study was conducted to determine the effects of biophoton treatment during in vitro maturation (IVM) and/or in vitro culture (IVC) on oocyte maturation and embryonic development in pigs. An apparatus capable of generating homogeneous biophoton energy emissions was placed in an incubator. Initially, immature pig oocytes were matured in the biophoton-equipped incubator in medium 199 supplemented with cysteine, epidermal growth factor, insulin, and gonadotrophic hormones for 22 h, after which they were matured in hormone-free medium for an additional 22 hr. Next, IVM oocytes were induced for parthenogenesis (PA) or provided as cytoplasts for somatic cell nuclear transfer (SCNT). Treatment of oocytes with biophoton energy during IVM did not improve cumulus cell expansion, nuclear maturation, intraoocyte glutathione content, or mitochondrial distribution of oocytes. However, biophoton-treated oocytes showed higher (p less than 0.05) blastocyst formation after PA than that in untreated oocytes (50.7% vs. 42.7%). In an additional experiment, SCNT embryos produced from biophoton-treated oocytes showed a greater (p less than 0.05) number of cells in blastocysts (52.6 vs. 43.9) than that in untreated oocytes. Taken together, our results demonstrate that biophoton treatment during IVM improves developmental competence of PA- and SCNT-derived embryos.

Bae, Y., Chungbuk National University, Cheongju, Republic of Korea | Koo, B., Chungbuk National University, Cheongju, Republic of Korea | Lee, S., Chungbuk National University, Cheongju, Republic of Korea | Mo, J., Chungbuk National University, Cheongju, Republic of Korea | Oh, K., Chungbuk National University, Cheongju, Republic of Korea | Mo, I.P., Chungbuk National University, Cheongju, Republic of Korea
The microbial community is known to have a key role during the rearing period of broilers. In this study, gut microbial composition and diversity were examined to evaluate the relationships between these factors and broiler growth performance. By applying 454-pyrosequencing of the V1-V3 regions of bacterial 16S rRNA genes, six fecal samples from four- and 28-day-old chickens from three broiler farms and 24 intestinal samples of broilers with heavy and light body weights were analyzed. Microbial composition assessment revealed Firmicutes to be the most prevalent phylum at farm A, while Proteobacteria were predominant at farms B and C. Fecal microbial richness and diversity indices gradually increased from four to 28 days at all three farms. Microbial diversity assessment revealed that small intestine microbial diversity was lower in heavy birds than in light birds. In light birds, the Firmicutes proportion was lower than that in heavy birds. In conclusion, each broiler farm revealed a specific microbial profile which varied with the age of the birds. The microbial communities appeared to affect growth performance; therefore, gut microbial profiles can be utilized to monitor growth performance at broiler farms.

This study evaluated the effect of a combination of acetaminophen and vitamin C (CAV) on reducing serum cortisol and tumor necrosis factor-alpha (TNF-alpha) concentrations in piglets vaccinated with foot-and-mouth disease (FMD) vaccine. Piglets were vaccinated with FMD vaccine and treated with CAV at concentrations of 0.0, 0.5, 1.0, and 2.0 kg/ton feed (P-CON, AD-1, AD-2, and AD-3, groups, respectively) for 5 days post-vaccination. Cortisol and TNF-alpha levels at 5 days post-treatment in the AD-1-3 groups were significantly lower than that in the P-CON group (p less than 0.05). There were no significant differences between AD-2 and AD-3 groups and non-vaccinated, non-CAV-treated piglets.

Lee, Y.A., Food and Rural Affair, Gimcheon, Republic of Korea | Kim, H.H., Food and Rural Affair, Gimcheon, Republic of Korea | Yang, D.K., Food and Rural Affair, Gimcheon, Republic of Korea | Cho, I.S., Food and Rural Affair, Gimcheon, Republic of Korea
Rabies virus (RABV) causes a neurological disease in warm-blooded animals that is nearly always fatal. In this study, we analyzed the matrix (M) genes in 10 Korean street RABV strains isolated from two Provinces during 2011-2013. The M genes in these 10 Korean strains were highly conserved during 1999-2013. Phylogenetic analysis revealed they were closely related to the M genes of RABVs isolated in northeastern China. Specific amino acid substitutions were identified in the KRVB1206, KRVF1301, and BV9901PJ strains. However, functional domains, including those involved in virus production and pathogenicity, were conserved in all 10 strains.

A study has been conducted to investigate the effect of two local herbs in Indonesia; Areca catechu nut and Sauropus androgynous leaf, combined with mineral block to treat gastro intestinal nematode in goats. A.catechu is well known to have anthelmintic property due to its alkaloid and tannin content, and S.androgynus also contains tannin, alkaloid and steroid that will enhance the anthelmintic property of those herbals. As many as 80 goats had been divided into 4 groups; 20 were treated with albendazole (Group A), 20 were given A.catechu and S.androgynus (Group B), 20 were given combination of A.catechu, S.androgynus, and mineral block (Group C), and 20 as negative control (Group D). The result revealed that herbal treatment showed significantly effective toward nematodes in gastro intestinal, demonstrated by declining egg worm of Group B and C. Body weight improvement and overall performance in Group C was higher compared to other groups. However, goats treated with albendazole showed slightly better results in the decreasing amount of egg worms found after treatment. Nevertheless, A.catechu and S.androgynus are potential anthelmintic herbal; combination with mineral block will enhance the anthelmintic activity. Therefore they are good options for treating helminthiasis in livestock.
