“…These observations are in agreement with the results of Zarei et al (2012). In a survey conducted in central Iran (Fallah, Saei-Dehkordi, & Mahzounieh, 2013), 14.5% of cooked RTE seafood samples were contaminated with L. monocytogenes; however, cooked RTE shrimp samples were free of L. monocytogenes. This observation is partially consistent with the results of present study.…”

A total of 104 Listeria monocytogenes isolates from 330 fish samples from three countries were characterized by multiplex PCR for serogrouping and virulence markers determination and tested for antibiotics resistance. A 53·8% of the isolates belonged to serogroup 1/2a, 3a; 32% belonged to 1/2b, 3b, 7; 14·4% belonged to 4b, 4d, 4e and 1% belonged to 1/2c, 3c. All isolates exhibited resistance to at least one antibiotic but the resistance rates varied among countries. The isolates exhibited high resistance to penicillin, rifampicin, clindamycin, erythromycin and tetracycline, but low resistance to amoxicillin-clavulanic acid, streptomycin, sulfamethoxazole-trimethoprim, gentamicin, chloramphenicol and kanamycin. When comparing countries, the resistance rate for rifampicin, clindamycin, erythromycin, tetracycline, amoxicillin-clavulanic acid varied among countries. When comparing serogroup, 1/2a, 3a exhibited the highest resistance to clindamycin, erythromycin, tetracycline and vancomycin while serogroup 4b, 4d, 4e exhibited the highest resistance to amoxicillin-clavulanic acid. All isolates carried inlA, inlC, inlJ and lmo2672. Listeriolysin S was carried by 42 and 30% of 4b and 1/2b isolates respectively. Significance and impact of the study: This is one of few studies to correlate antibiotic resistance with Listeria monocytogenes serogroups. The study also compared the antibiotic resistance and serogroups of L. monocytogenes isolates from three countries in one single study. The findings of this study will be helpful in improving data on the antibiotics resistance of L. monocytogenes in developing countries and enriches the epidemiological and public health studies of L. monocytogenes.

“…Recently, Fallah et al . () reported the presence of L. monocytogenes in 16 (4.83%) of 331 raw seafood samples in Iran, and also the higher prevalence of the pathogen in freshwater fish (11.4%) compared with those in seawater fish (1.80%) and shrimp (1.69%). In our study, seafood samples were obtained from Black Sea and Marmara Sea but not from freshwaters which would be the possible explanation for the absence of the pathogen in seafood.…”

In the present study, a total of 512 food samples composed of raw milk, dairy products, meat/meat products, chicken meat, seafood and raw vegetables were analyzed for the presence of Listeria monocytogenes. The results of the standard identification methods showed that 20 (3.9%) of the analyzed samples were found to harbor this pathogen. Further, 8.4% (13/155) of chicken meats, 0.9% (1/105) of meat/meat products and 13.6% (6/44) of fresh vegetables were contaminated with L. monocytogenes. Interestingly, only 18 of these isolates gave expected band size when they were subjected to molecular confirmation by polymerase chain reaction (PCR). Multiplex PCR serotyping of the strains revealed that 66.6% (12/18) of which belonged to serotype 1/2a (or 3a), 5.6% (1/18) to serotype 1/2b (or 3b, 7), 5.6% (1/18) to serotype 1/2c (or 3c) and 11.1% (2/18) to serotype 4b (or 4d, 4e). Two strains could not be serotyped by multiplex PCR. The strains were also evaluated by disk diffusion assay for their susceptibility to 15 commonly used antimicrobials. Antimicrobial resistance was most frequently observed for clindamycin (94.4%), followed by streptomycin and kanamycin (88.9%); penicillin (72.2%), tetracycline and gentamicin (66.7%); quinopristin/dalfopristin and erythromycin (61.1). Interestingly, 13 strains were resistant to more than five antibiotics. All strains were susceptible to linezolid, teicoplanin and vancomycin. Practical Applications Listeria monocytogenes is one of the most important foodborne pathogens responsible for several outbreaks and cases of listeriosis in human. This study focused on the prevalence of L. monocytogenes in different raw and ready‐to‐eat foodstuffs, and serotype distribution among the isolates. Antibiotic resistance profiles of the isolates were also reported. Information and relief provided to consumers could help elaborate public health and food safety.
