Abstract |
Salmonellosis is of great economic concern in all phases of the poultry industry, from production to marketing, leading to severe economic losses. Monitoring the source of the bacterial contamination has fundamental importance in the spreading of salmonellosis. We applied a ligation-mediated PCR method, PCR MP (PCR melting profile), to type S. enterica ssp. enterica ser. Enteritidis (56 strains) and 43 control strains classified to other serovars isolated from poultry. We demonstrated the PCR MP potential for salmonellosis spreading monitoring. Our rapid test presents higher discriminatory power (0.939 vs. 0.608) compared to current molecular subtyping tool such as pulsed-field gel electrophoresis (PFGE), which ineffectiveness underlies the high degree of clonality of S. Enteritidis. PCR MP was found to be a highly discriminating, sensitive and specific method that could be a valuable molecular tool, particularly for analyzing epidemiological links of limited number of S. enterica ser. Enteritidis strains. |
