Subtyping ofSalmonellaFood Isolates Suggests the Geographic Clustering of Serotype Telaviv

Abstract

Salmonella is commonly found in a variety of food products and is a major cause of bacterial foodborne illness throughout the world. In this study, we investigated the prevalence and diversity of Salmonella in eight different food types: sheep ground meat, cow ground meat, chicken meat, cow offal, traditional Sanliurfa cheese, unripened feta cheese, pistachios, and isot (a spice blend of dried red peppers specific to Sanliurfa), traditionally and commonly consumed in Turkey. Among 192 food samples, Salmonella was detected in 59 samples, with the highest prevalence in raw poultry parts (58%) and offal (58%) samples, while Salmonella was not detected in pistachios and dried red pepper. Resultant Salmonella isolates were characterized by serotyping, multilocus sequence typing (MLST), and pulsed-field gel electrophoresis (PFGE). Ten different serotypes represented 10 MLST sequence types (STs) with 1 novel ST and 17 PFGE types. Antimicrobial resistance profiling revealed that 30.5% of the isolates were resistant to two or more antimicrobials. Salmonella enterica subsp. enterica serotype Telaviv, which is rare throughout the world, was the second most common serotype isolated from food samples in this study, suggesting that this serotype might be one of the subtypes that is endemic to Turkey.

Prevalence of Pathogens in Poultry Meat: A Meta-Analysis of European Published Surveys

“…After assessing all the information from the recovered publications, seventy-eight primary studies [6,12,13,14,15,16,17,18,19,20,21,22,23,24,25,26,27,28,29,30,31,32,33,34,35,36,37,38,39,40,41,42,43,44,45,46,47,48,49,50,51,52,53,54,55,56,57,58,59,60,61,62,63,64,65,66,67,68,69,70,71,72,73,74,75,76,77,78,79,80,81,82,…”

DETERMINATION OF in vitro BIOFILM FORMATION ABILITIES OF FOOD BORNE Salmonella enterica ISOLATES

“…Serovar Infantis, Enteritidis, Kentucky and Telaviv isolates were used, of which Infantis, Enteritidis and Kentucky serovars are among the most common isolated serovars in Turkey. Interestingly, Telaviv has also been commonly isolated from food samples in Turkey although it is among the rare serovars throughout D. Aksoy the world (Ozdemir & Acar 2014, Erol 1999, Durul et al 2015. The results showed that both the prolonged incubation period and the temperature effected the biofilm formation capacities depending on the serovars.…”

Antibacterial activity of cinnamon oil against multidrug-resistant Salmonellaserotypes and anti-quorum sensing potential

“…enterica strains (n =56), isolated from chicken meat, and cow ground meat and offal, were obtained from the Department of Food Engineering of the Middle East Technical University (METU, TURKEY) and in their previous study molecular confirmation of these strains was conducted by determining invA gene (F:5'-GAACCCTCAGTTTTTCAACGTTTC-3', R:5'-TAGCCGTAACAACCAATACAAATG-3') by PCR (Kim et al 2007) and serotyping of strains was performed using the White-Kauffmann-Le Minor scheme (Grimont and Weil 2007) at the laboratory of Public Health Agency of Turkey in Ankara. Antimicrobial resistance of fifty-six S. enterica isolates have been phenotypically determined by agar disk diffusion (CLSI 2016) test using eighteen antibiotics, including amikacin (AK) 30 μg, ampicillin (AMP) 10 μg, amoxicillin-clavulanic acid (AMC) 20/10 μg, cefoxitin (FOX) 30 μg, cephalothin (KF) 30 μg, ceftiofur (EFT) 30 μg, ceftriaxone (CRO) 30 μg, chloramphenicol (C) 10 μg, ciprofloxacin (CIP) 5 μg, ertapenem (ETP) 10 μg, gentamicin (GN) 10 μg, imipenem (IPM) 10 μg, kanamycin (K) 30 μg, nalidixic acid (N) 30 μg, streptomycin (S) 10 μg, sulfisoxazole (SF) 10 μg, sulfamethoxazole-trimethoprim (SXT) 10 μg, and tetracycline (T) 30 μg discs and also the antimicrobial gene resistance profiles of these strains have been investigated by screening 21 antimicrobial resistance genes shown in Table 1, encoding resistance against Class A beta-lactamase, ceftiofur, ceftriaxone, beta-lactamases, chloramphenicol, streptomycin, gentamicin, kanamycin, trimethoprim, sulfisoxazole, and tetracycline (Acar et al 2017, Durul et al 2015. The isolates that show resistance to three or more antibiotic classes (with resistance to at least one antibiotic from each class) were considered to be MDR.…”
