The spread of antibiotic-resistant Enterobacteriaceae in the community is one of the main challenges for antibiotic treatment of community-onset infections. We evaluated the microbiological and molecular characteristics of stool samples from adults with comprehensive health examinations. Of 109 fecal samples, bacterial growth was observed in 86 samples and 61 gram-negative bacterial isolates were identified, of which 45 were Escherichia coli isolates (73.8%). Two isolates of Raoultella showed imipenem resistance, and both E. coli and Citrobacter freundii showed intermediate resistance to imipenem. Colistin resistance was identified in isolates of Klebsiella variicola and Salmonella subterranean, but no isolates carried mcr-1. As for E. coli genotypes, 35 sequence types were identified. bla<sub>TEM-1</sub>, bla<sub>TEM-30</sub>, and bla<sub>CTX-M</sub> were identified in 15, 1, and 4 E. coli isolates, respectively. In addition, all four Klebsiella pneumoniae isolates carried bla<sub>SHV</sub>. Many genotypes that have been identified in isolates causing human infections were found in isolates in this study. There is a need to control the rise and spread of antibiotic-resistant pathogens by fecal carriage.

This study was conducted to make certain that the intramuscular fat score at 13th rib could represent the fat content of whole loin from Hanwoo in Korea beef grading system. A total 42 loins from 23 carcasses of grade 1<SUP>++</SUP>, 16 carcasses of grade 1<SUP>+</SUP>, and 3 carcasses of grade 1 of Hanwoo were used for this study. The crude fat content and intramuscular fat score at the 1<SUP>st</SUP>, 6<SUP>th</SUP>, and 13<SUP>th</SUP> rib, and the last lumbar position of loin were measured. The crude fat content was the highest at the 6<SUP>th</SUP> rib of loin from the carcasses of grade 1<SUP>++</SUP> and 1<SUP>+</SUP> (p<0.05). There were no significant difference of the intramuscular fat scores measured by image analysis and beef marbling score (BMS) between the 6th and 13<SUP>th</SUP> rib of loin from the carcasses of 1<SUP>++</SUP> and 1<SUP>+</SUP> and that were significantly higher than intramuscular fat scores at the 1<SUP>st</SUP> rib and the last lumbar position of the loin. From the results, we conclude that the intramuscular fat score at the 13<SUP>th</SUP> rib can represent the fat content of loin when meat graders decide the grade of Hanwoo carcass.
