    Abstract / Zusammenfassung

    The purpose of this study was to determine the prevalence and the number of Listeria monocytogenes in 184 samples of fresh poultry products sold in traditional markets and supermarkets in Bandung, West Java, Indonesia, and also to determine the antimicrobial resistance pattern and molecular characterization of the isolated L. monocytogenes strains. The samples were analyzed following ISO 11290-1: 1996 and ISO 11290-2: 1998. Disc diffusion method was applied for antimicrobial susceptibility test and multiplex polymerase chain reaction was applied for molecular serotyping of the isolated L. monocytogenes. Overall L. monocytogenes was detected in 15.8 % of the fresh poultry products, with prevalence of 15.2 % and 16.3 % for traditional markets and supermarkets samples respectively. There was no significant difference between traditional markets and supermarkets regarding the prevalence and the count number of L. monocytogenes. The average L. monocytogenes count in poultry products sold in traditional markets was 1.08 log cfu/g, and 1.03 log cfu/g for supermarkets. The contamination level of L. monocytogenes was < 10 cfu/g in 87.5 %, between 10 and 100 cfu/g in 9.8 %, between 100 and 1000 cfu/g in 2.2 %, and > 1000 cfu/g in 0.5 % of the samples. All 29 isolates in this study belong to the molecular serogroup IIb comprising the serovars 1/2b, 3b and 7. 27.6 % (8/29) isolates were resistant to at least one of ten antimicrobials tested, and 72.4 % (21/29) of the isolates were susceptible to all antimicrobials tested. Among 29 isolates, 17.2 %, 6.9 %, 6.9 % and 3.4 % were resistant to penicillin, ampicillin, erythromycin, and a combination of ampicillin and penicillin respectively. The results of this study reveal that there is wide spread cross contamination and emerging antibiotics resistant of L. monocytogenes isolated from fresh poultry products sold in study area. There are strong needs to improve this condition by improving good hygienic practices and prudent use of antimicrobial drugs at all level of poultry production chain.
