The WTO/DDA Negotiation on the Fisheries Subsidies started by DDA(Doha Development Agenda : 2001.11)at early 2002 has been held about 20 times until the fist half of 2005. The Negotiation will be terminated until the end of 2005 but now, it is impossible to predict the exact conclusion of the Negotiation. There is a sharp conflict of opinion on the WTO/DDA Negotiation on the Fisheries Subsidies between FFG(Fish Friends Groups : USA, New Zealand etc) and Anti-FFG(Rep. Korea, Japan etc). The Fisheries Subsidies is regulated by the WTO/DDA Negotiation that regulates on the subsidies of industrial products, fisheries products, forest products. Considering the progress of the WTO/DDA Negotiation on the Fisheries Subsidies, Guidelines for the Fisheries Subsidies Negotiation were established in Doha Ministerial Declaration at 2001 and a necessity of a special regulation on the Fisheries Subsidies has been discussed from 2002 to 2004. After june, 2004, the Negotiation was proceeding as Rep. Korea, Japan and Taiwan agreed with discussing a special regulation on the Fisheries Subsidies and At 1st, August, 2004, they reached an agreement on a necessity of a special regulation on the Fisheries Subsidies. At Feb, 2005, discussion was suspended because of presenting the joint proposal from 3 countries(Rep. Korea, Japan and Taiwan) and now discussion on the Fisheries Subsidies is giving the first consideration to classification of prohibited/non-actionable subsidies, S&D of a developing countries, small fisheries, problems of farming, grace period etc. From now on, Considering the 18th~the 20th negotiations, it is expected that discussion of fisheries subsidies regulation including property and range of prohibited/non-actionable subsidies, S&D of a developing countries, a definition of small fisheries is accelerated. In this point of view, this paper analyzed and arranged every country's proposals holding our own position and took a survey to fishermen and fisheries experts about prohibited/non-actionable subsidies. In addition, this paper intends to suggest the way of future-negotiation and provides essential data to help government's policy making through analyzing prohibited/ non-actionable subsidies, farming subsidies, S&D of a developing countries, small scale fisheries.

The complete nucleotide sequence of pKH4, a small multidrug resistance (smr) plasmid isolated from multidrug resistant Staphylococcus aureus SA5, was determined. Sequence analysis has revealed that pKH4 has two open reading frames for Rep and Smr proteins. The comparison of the amino acid sequence of Smr protein of pKH4 with those of other Smr proteins of various Staphylococcus showed that Smr protein of pKH4 is a new member of the SMR family.

The emergence and dissemination of Salmonella genomic island 1 (SGI1) are strongly associated with the occurrence of multidrug-resistant (MDR) enterobacteria in humans and animals. Diverse SGI1s have been reported among Salmonella enterica and Proteus mirabilis in several countries. We aimed to characterize SGI1 in P. mirabilis isolates from humans and chickens in Chungcheong Province, Korea. A total of 44 P. mirabilis isolates were recovered from humans (n = 20) and chickens (n = 24). Antimicrobial susceptibility was determined by disk diffusion assay. To detect and characterize SGI1s, PCR amplification and PCR mapping experiments were performed. Repetitive extragenic palindromic-PCR (REP-PCR) was performed to assess the clonality of the isolates. The four P. mirabilis strains (16.7%) from chicken harbored a SGI1, whereas none of the isolates from clinical specimens contained SGI1. The SGI1s detected in our study were all confirmed as SGI1-PmABB harboring aminoglycoside-resistant genes (aacCA5 and aadA7). In P. mirabilis isolates, the presence of SGI1-PmABB was significantly correlated with high resistance rates of the isolates to antimicrobial agents, such as gentamicin, streptomycin, and spectinomycin. Moreover, the four SGI1-bearing isolates showed the same REP-PCR patterns and that suggested both horizontal and clonal spread of the isolates. This study is the first attempt to determine SGI1s in P. mirabilis isolates in Korea. We confirmed that P. mirabilis isolates carrying SGI1-PmABB were distributed at poultry farms in Korea. The present study emphasizes the need for continuous monitoring of SGI1s to prevent spreading of the MDR genomic islands among P. mirabilis isolates from humans and animals.

Bacterial fruit blotch (BFB) caused by Acidovorax citrulli is a devastating disease found in many cucurbits cultivation fields. The genetic diversity for 29 strains of A. citrulli collected from various cucurbits in South Korea was determined by DNA fingerprinting with a pathogenicity test, multi locus analysis, Rep-PCR (repetitive sequence polymerase chain reaction), and URP (universal rice primers) PCR bands. Two distinct groups (Korean Clonal Complex, KCC1 and KCC2) in the population were identified based on group specific genetic variation in the multi locus phylogeny using six conserved loci and showed a very high similarity with DNA sequences for representative foreign groups [the group I (CC1-1 type) and the group II (CC2-5 type)] widely distributed worldwide, respectively. Additionally, in the case of phaC, a new genotype was found within each Korean group. The KCC1 was more heterogeneous compared to the KCC2. The KCC1 recovered mainly from melons and watermelons (ratio of 6 : 3) and 15 of the 20 KCC2 strains recovered from watermelons were dominant in the pathogen population. Accordingly, this study found that two distinct groups of differentiated A. citrulli exist in South Korea, genetically very similar to representative foreign groups, with a new genotype in each group resulting in their genetic diversity.
