Abstract :

Objective The presence of Salmonella enterica serovar Typhimurium becomes a concern in relation to the safety of drinking water and ice. We detected and enumerated the bacteria from ice and beverages collected from several areas in Jakarta. Most Probable Number (MPN) and multiplex PCR method were used. Three sets of primers were used rfbJ, fliC, and fljB. Two Multiplex PCR's were performed, the first is to detect the presence of Salmonella and the second is to confirm the positive isolate of S. enterica serovar Typhimurium. Results A total of 50 beverages and 50 ices were collected MPN result ranged from 11,000 MPN/ml. The highest MPN value 11,000 MPN/ml. The first Multiplex PCR result from beverages, 58% positively contained Salmonella spp. with amplification of fliB gene and no amplification of rfbJ and fliC genes. For ice samples, 2% positively contained Salmonella spp. with rfbJ gene amplification, 62% fliB gene and no amplification of fliC gene. The second Multiplex PCR results from beverages identified 21 positive isolates of S. enterica serovar Typhimurium. In which, 17 isolates contained fljB gene and 4 isolates contained both fljB and rfbJ genes. From ice, 17 isolates having both rfbJ and fljB genes. Keywords: Salmonella enterica serovar Typhimurium, Ice and beverages, Virulence, PCR
