In this study, eight primers were used to detect genetic variability and phylogenetic relationships among the eighteen Salmonella strains by the arbitrary-primed PCR(AP-PCR) techniques. Five strains of Salmonella typhimurium, four strains of S entertidis, three strains of S choleraeuis, three strains of S gallinarum and three strains of S pullorum were typed by AP-PCR. The number of AP-PCR bands detected per each primer varied from 39 to 52, with an average of 43.6. A total of 349 AP-PCR bands were generated and among them, 185 bands(53.0%) were polymorphic. Among the primers, GEN 703 and GEN 708 primer showed a high level of polymorphism with 0.682 and 0.676, respectively. But GEN 603, GEN 604 and GEN 607 primer showed a low level of polymorphism with 0.404, 0.460 and 0.472, respectively. Therefore, the these primers will be the most effective for AP-PCR analysis of Salmonella strains. The level of polymorphism of S typhimurium CU 2001(0.77) was similar to that of S typhimurium CU 2002(0.77) and lower than those of other strains such as S typhimurium CU 2003(0.63), S typhimurium ATCC 14028(0.50) and S typhimurium CU 2004(0.43). The level of polymorphism of S enteritidis ATCC 13076(0.83) was similar to that of S enteritidis CU 2005(0.83) and lower than those of other strains such as S enteritidis CU 2006(0.63) and S enteritidis CU 2007(0.58). The level of polymorphism of S choleraeuis CU 2009(0.67) was similar to that of S choleraeuis CU 2010(0.67) and higher than those of other strains such as S choleraeuis CU 2008(0.53). The level of polymorphism of S gallinarum CU 2011(0.70) was similar to that of S gallinarum CU 2012(0.70) and higher than those of other strains Such as S gallinarum ATCC 9184(0.60). The level of polymorphism of S pullorum CU 2013(0.80) was similar to that of S pullorum CU 2014(0.80) and higher than those of other strains such as S pullorum No 11(0.53). Therefore, the AP-PCR analysis will be used a powerful tool for estimating genetic variation and phylogenetic relationships among Salmonella strains.
