“…The standard therapy for listeriosis is ampicillin or penicillin G combined with an aminoglycoside, such as streptomycin or gentamicin (26). In this study, MIC value of penicillin G, ampicillin and gentamicin were detected 0.5 μg/ml, 0.125-0.25 µg/ml and 0.5-1 µg/ml respectively which were similar to those reported by other authors (13,10,15).…”

“…On the other hand tetracycline resistance among L. monocytogenes isolates has been recently observed by some researchers (1,10,17,26,27). High prevelance of tetracycline resistance in food isolates may be partly due to the frequent use of tetracycline in animal production (26).…”

“…Trimethoprim and sulphonamide resistant L. monocytogenes isolated from various food were reported in recent studies (17,26). This resistance is important as trimethoprimsulfamethoxazole treatment has been successfully used for listeriosis patients with beta-lactams allergy.…”

“…On the other hand MIC values for penicilin G was slightly higher than those reported by Zhang et al, (27) as 4 µg/ml. Penicillin G, ampicillin and gentamicin resistance of L. monocytogenes are mentioned in several studies (1,21,17,26).…”

“…Antimicrobial resistance of L. monocytogenes has been conscientiously traced since the first emergence of acquired resistance in L. monocytogenes isolates in France in 1988 (20). Other resistant isolates to one or more antibiotics obtained from food and human listeriosis have been reported by recent studies (26,27).…”

Summary:This study was designed to evaluate public health risks in respect to listeriosis due to consumption of local raw milk cheese sold in villages and public bazaars of Nigde. In addition, this study aims to contribute to the treatment process of listeriosis by determining serotype distribution and antimicrobial susceptibility profiles of the isolates. In the study, two of cheese (1 %) samples of total 200 raw milk cheese samples (100 white cheeses and 100 tulum cheeses) were found contamined with L. monocytogenes. Serotype distribution of the isolates were determined as 1/2a (white cheese isolate) and 4a (tulum cheese isolate). Finally, antimicrobial resistance profiles of the isolates against 11 antibiotics (tetracycline, ciprofloxacin, gentamicin, ampicillin, erythromycin, trimethoprim, vancomycin, chloramphenicol, nalidixic acid, penicillin G and sulphanilamide) were determined and the MIC values were specified by a microdilution method. Both of the isolates were found to be resistant to nalidixic acid but sensitive to the others analysed. As a result, although low L. monocytogenes prevalance rates were detected in this study, it is a public health concern to isolate serotype 1/2a which is secondly incriminated serotype to cause human listeriosis. In addition, it is important in terms of public health to continue surveillance of emerging antimicrobial resistance among L. monocytogenes isolated especially from foods of animal origin though incidence of antibiotic resistance in L. monocytogenes isolates is rare.Keywords: Antimicrobial susceptibility, cheese, Listeria monocytogenes, microdilution, serotype distribution.Niğde'de satışa sunulan çiğ sütten yapılmış peynir örneklerinden elde edilen Listeria monocytogenes izolatlarının serotip dağılımının ve antimikrobiyel duyarlılık profilinin belirlenmesi Özet: Bu çalışma, Niğde ili köy ve pazarlarında tüketime sunulan çiğ sütten yapılmış peynirlerin listeriozis açısından taşıdığı halk sağlığı risklerini değerlendirmek ve peynirlerden elde edilen izolatların serotip dağılımını ve antimikrobiyel duyarlılık profillerini belirleyerek tedavi sürecine katkıda bulunmak amacıyla planlanmıştır. Çalışma sonucunda 200 çiğ sütten yapılmış peynir örneğinden (100 beyaz peynir ve 100 tulum peyniri) ikisinin (% 1) L. monocytogenes ile kontamine olduğu bulunmuştur. L. monocytogenes izolatlarının serotip dağılımı 1/2a (beyaz peynir izolatı) ve 4a (tulum peyniri izolatı) olarak belirlenmiştir. Son olarak izolatların 11 antibiyotiğe (tetrasiklin, siprofloksasin, gentamisin, ampisilin, eritromisin, trimetoprim, vankomisin, kloramfenikol, nalidiksik asit, penisilin G ve sülfonilamid) karşı direnç profilleri belirlenmiş ve MIC değerleri mikrodilüsyon metodu ile ortaya konmuştur. İzolatların her ikisinin de nalidiksik asite dirençli, diğer antibiyotiklere duyarlı olduğu tespit edilmiştir. Sonuç olarak incelenen örneklerde L. monocytogenes prevalansının çok düşük düzeylerde bulunmasına karşın insan listeriozisinden ikinci sırada sorumlu tutulan 1/2a serotipinin belirlenmiş olması h...

We examined antimicrobial susceptibility and serotypes of 33 isolates collected from ready-to-eat seafood and food processing environments. The isolated strains belonged to the 1/2b (73%), 4b (15%), and 1/2a (12%) serotypes; 11 of the obtained environmental swab samples belonged to the 1/2b serogroup. Antimicrobial resistance to benzyl penicillin (100%), clindamycin (100%), oxacillin (100%), ampicillin (97%), and tetracycline (18%) was detected, and 27/33 isolates (82%) showed resistance to four antibiotics and 6/33 (18%) were resistant to five. Total typing by automated repetitive sequence-based PCR revealed that the 33 isolates grouped into four distinct clusters with significantly correlated serotypes. These findings provide important information about the safety of ready-to-eat seafood and suggest that control measures should be adopted in order to mitigate the risk to humans posed by contaminated seafood.
