The strains of Salmonella othmarschen and Norovirus isolated from outbreak A, the funeral ceremonies incidents in Ouri-shi of Oyeonggido in, 2007, were subjected to genotyping by using PFGE and extraction of RNA by using RT-PCR. 24 Salmonella othmarschen were isolated from 37 cases (patients 12 cases, cookers 4 cases, foods 7cases, knife, kitchen board, dish towel 4 cases, etc) and PFGE patterns showed that 22 strains isolated from the same incident were almost of the same pattern and 2 strains exhibited 50% of the pattern. Antimicrobial susceptibility patterns were such that there were 22 case susceptibility patterns and 2 case resistance patterns (strain 4: AM, CF, CIP, NA, TE TIC and strain 13: CF, CZ). Norovirus G1 (1case), Norovirus G2 (7cases), Norovirus G1,G2 (1case) were detected by using RT-PCR. The fine typing ability and reliability of PFGE and BioNumerics are helpful for establishing out the foodborne pathogens of outbreaks.
