<sec><b>Objectives</b><p>Few long-term studies have been conducted on the serotype and antibiotic resistance patterns of <italic>Salmonella</italic> speices (spp.) The aim of this study was to determine the serotypes and antibiotic resistance patterns of <italic>Salmonella</italic> spp. isolated at Jeollanam-do in Korea from 2004 to 2014.</p></sec><sec><b>Methods</b><p>A total of 276 <italic>Salmonella</italic> samples were evaluated. Serotyping was carried out according to the Kauffmann–White scheme. Antibiotic susceptibility was determined using the Vitek II system with an AST-N169 card.</p></sec><sec><b>Results</b><p>A total of 22 different serotypes were identified, and the major serotypes were <italic>Salmonella</italic> Enteritidis (116 strains, 42.0%) and <italic>Salmonella</italic> Typhimurium (60 strains, 21.7%). The highest resistance was observed in response to nalidixic acid (43.4%), followed by ampicillin (40.5%) and tetracycline (31.6%). Resistance to nalidixic acid was detected in 81.0% of <italic>S</italic>. Enteritidis. Multidrug resistance was detected in 43.3% of <italic>Salmonella</italic> spp. <italic>S</italic>. Enteritidis and <italic>S</italic>. Typhimurium presented the highest resistance (98.3%) and multidrug resistance rate (73.3%), respectively. The most highly observed antibiotic resistance pattern among <italic>Salmonella</italic> spp. in this study was ampicillin-chloramphenicol (14 strains, 5.7%),</p></sec><sec><b>Conclusion</b><p>Overall, <italic>S</italic>. Enteritidis and <italic>S</italic>. Typhimurium showed higher antibiotic resistance than the other <italic>Salmonella</italic> serotypes tested in this study. Our study will provide useful information for investigating the sources of <italic>Salmonella</italic> infections, as well as selecting effective antibiotics for treatment.</p></sec>
