  • In order for monitoring of pathogenic bacterial contamination in the freshly slaughtered poultry meats produced in Gyeong-Nam province, we first isolated 4 strains of Salmonella spp. and 32 strains of Enterococcus faecalis from the total 164 samples, then we analyzed potential virulence gene profiles of the bacterial isolates by PCR using species-specific primer. The potential virulence genes we selected in this study were stn, invA, fimA, spvR, and spvC for the isolates of Salmonella spp. and those of esp, cylM, cylA, cylB, gelE, fsrA, fsrB, and fsrC were for the isolates of E. faecalis. The PCR results showed that all 5 virulence genes were detected simultaneously in the all isolates of Salmonella spp. However, there was a diverse occurrence pattern of the virulence genes in the case of E. faecalis. The gene for enterococcal surface protein (esp) was not detected among the isolates (0/32), and the haemolysin gene prevalence rate of cylA, cylB, and cylM were 3.1% (1/32), 9.3% (3/32), and 9.3% (3/32), respectively. Moreover, the genes of gelE, fsrA, fsrB, and fsrC that associated with gelatinase activity were detected in the rate of 53.1% (17/32), 53.1% (17/32), 53.1% (17/32), and 53.1% (17/32), respectively. In conclusion, in the isolates of Salmonella spp., all possessed 5 virulence genes tested, suggesting that they are all related with each other clonally. However, in the case of E. faecalis isolates, the occurrence of the haemolysin genes (cylM, cylA, cylB) and the gelatinase genes (gelE, fsrABC) was highly variable among the isolates.

  • Porcine respiratory coronavirus (PRCV) is antigenically related to transmissible gastroenteritis virus (TGEV). Differential serological diagnosis between PRCV and TGEV infection is not possible with the classical sero-neutralization test. Infection with PRCV or TGEV induces antibodies which neutralize both viruses to the same titer. However, the enzyme-linked immunosorbent assay (ELISA) and polymerase chain reaction (PCR) can differentiate between PRCV and TGEV infection. This study was carried out to investigate the prevalence of PRCV infection of swine in Gyeongnam province. A total of 391 serum samples from 37 herds in Gyeongnam were examined for antibody to PRCV using blocking ELISA. All serum samples were collected from 130- to 150-day-old pigs between August and December 2006. By ELISA, 182 out of 391 sera tested (46.5%) and 29 out of 37 sample herds (78.4%) were positive against PRCV. Our data suggested that seropositive herds for PRCV are distributed diffusely throughout Gyeongnam. The PCR methods were established to diagnose PRCV spike protein (S) gene. PCR were conducted to identify the PRCV genome against 150 pigs in PRCV antibody positive herds.

  • Characterization of spatio-temporal variations in $PM_{2.5}$ in Gyeongnam (GN) province during 2015-2016 was investigated to assess the air quality in this area in terms of fine particles. Yearly mean concentrations of $PM_{2.5}$ ranged from 19.1 to $29.5{\mu}gm^{-3}$. High concentrations of $PM_{2.5}$ were observed in spring ($21.2-30.3{\mu}gm^{-3}$) and winter ($20.2-30.3{\mu}gm^{-3}$). Low concentrations of $PM_{2.5}$ were generally observed in fall ($16.2-23.2{\mu}gm^{-3}$). $PM_{2.5}$ concentration was highest in the morning (10 AM). The fractions of $PM_{2.5}$ in $PM_{10}$ were 0.51-0.62 and two were significantly correlated (r=0.779-0.830), suggesting common sources (fossil fuel combustion, mobile sources, etc). CO was significantly correlated with $PM_{2.5}$ in highly urbanized areas such as the city of Changwon (CW, r=0.711), compared to other air pollutants ($SO_2$, $NO_2$, and $O_3$), suggesting dominance of industrial combustion sources.

  • In order to figure out the characteristics of radionuclides concentrations of nine provinces, we analyzed uranium and radon in 681 samples of groundwater. Most of uranium concentrations in each province were less than $10{\mu}g/L$, and Gyeongnam, Jeonnam, Jeju provinces did not have groundwaters exceeding the US EPA drinking water MCL ($30{\mu}g/L$) of uranium. The ratio of radon values exceeding US EPA drinking water AMCL (4,000 pCi/L) was 22.6% (154/681) and Gyeongnam and Jeju provinces had no groundwaters exceeding the AMCL (alternative maximum contaminant level). Uranium and radon concentrations in groundwaters of Gyeonggi, Chungbuk, Jeonbuk, Chungnam mainly composed of the Mesozoic granite and the Precambrian gneiss were relatively high, but the concentrations of Gyeongnam and Jeju widely comprised of the sedimentary rock and the volcanic rock were relatively low. A week correlation between uranium and radon values showed in Gangwon, Chungbuk, Gyeonggi provinces.

  • This study was conducted to determine the carbon (C) and nitrogen (N) distribution within tree components (i.e., stem, branches, leaves, and roots) of the Japanese larch (Larix kaempferi Carriere) plantation and natural oriental cork oak (Quercus variabilis Blume) stands. Fifteen Japanese larch and 15 oriental cork oak trees were destructively sampled to compare the C and N stocks in the components of the trees from three different regions-Hadong-gun, Hamyang-gun and Sancheong-gun-in Gyeongnam Province, South Korea. Species-specific allometric equations were developed to estimate the C and N contents in the tree components based on the diameter at breast height (DBH). There were differences in mean C and N concentrations between the Japanese larch and the oriental cork oak. The mean C concentrations of the tree componentswere significantly higher in Japanese larch than in oriental cork oak; whereas, the N concentration in the stems was significantly lower in Japanese larch than in oriental cork oak. The allometric equations developed for C and N content were significant (p < 0.05) with a coefficient of determination ($R^2$) of 0.76 to 0.99. The C and N stocks in the tree components do not appear to be affected by the species such as Japanese larch plantations and oriental cork oak stands. This study emphasizes the importance of C and N concentrations to estimate the C and N distribution according to tree components in different tree species.

  • The objective of this study was to determine the infection patterns of etiological agents causing calf diarrhea in the Gyeongnam province, Korea. In this study, from January 2011 to December 2011, feces and necropsy specimens from 249 calves diagnosed with diarrhea (<7 months old) were examined by reverse transcriptase-polymerase chain reaction assay and bacteria & coccidium isolation for detection pathogenic organism. The results of this study showed that 78 cases (31.3%) in spring, 71 cases (28.5) in summer, 62 cases (24.9%) in fall and 38 cases (15.3%) in winter were diagnosed with calf diarrhea, respectively. Calf diarrhea-causing pathogens were diagnosed as bacteria 113 (45.4%), viruses 97 (39.0%), coccidium 1 (0.4%), unknown cases 13 (5.2%), and mixed infections 25 (10.0%). We isolated three virus types from fecal samples (97), which were classified as BVD 64 (66.0%), BRV 21 (21.6%), and BCV 12 (12.4%). Moreover, co-infected pathogens were 25 cases, consisting with BVD & BRV 11 (44%), BVD & BCV& BRV 7 (28.0%), E. coli & BCV 3 (12%), and BVD & IBR 1 (4.0%). In summary, we demonstrated that the enteropathogens of bacteria, viruses, and parasite were detected in samples from cattle with diarrhea, principally in young calves less than 7 months of age. Future studies of infectious diarrhea in cattle should include assays for this etiologic agent.
