چکیده

In Listeria monocytogenes serotype 4b isolates from sporadic listeriosis, heavy metal resistance was primarily encountered in certain clonal groups (ECI, ECII, and ECIa). All arsenic-resistant isolates harbored the arsenic resistance cassette previously identified in pLI100; ECIa harbored additional arsenic resistance genes and a novel cadmium resistance determinant in a conserved chromosomal locus.

Heavy-metal and benzalkonium chloride resistance of Listeria monocytogenes isolates from the environment of turkey-processing plants.

The resistance of Listeria monocytogenes to cadmium and arsenic has been used extensively for strain subtyping. However, limited information is available on the prevalence of such resistance among isolates from the environment of food-processing plants. In addition, it is not known whether the resistance of such isolates to heavy metals may correlate with resistance to quaternary ammonium compo...

Prevalence and Antibiotic Susceptibility of Listeria Monocytogenes Isolated from Retail Ready-to-Eat Meat Products in Gorgan, Iran

Background and Objectives: Listeria monocytogenes are known as an emerged foodborne pathogen and considered as a severe health risk. In the present study, prevalence and antibiotic resistance of L. monocytogenes isolated from ready-to-eat meat products in Iran were assessed. Materials and Methods: A total of 200 ready-to-eat meat products, including chicken meat (wing, breast, and leg), lamb a...

Benzalkonium chloride and heavy-metal tolerance in Listeria monocytogenes from retail foods.

Phenotypic and genotypic tolerance in 71 Listeria monocytogenes isolates from different varieties of foods to benzalkonium chloride (BC) and cadmium were investigated by susceptibility test and molecular methods. To investigate the role of efflux pumps in BC tolerance, reserpine, an efflux pump inhibitor, was added to the BC tolerant strains. Tolerance to BC and cadmium were 26.8% (19/71) and 4...

Epidemic clone I-specific genetic markers in strains of Listeria monocytogenes serotype 4b from foods.

Listeria monocytogenes contamination of ready-to-eat foods has been implicated in numerous outbreaks of food-borne listeriosis. However, the health hazards posed by L. monocytogenes detected in foods may vary, and speculations exist that strains actually implicated in illness may constitute only a fraction of those that contaminate foods. In this study, examination of 34 serogroup 4 (putative o...

Characterization of Listeria monocytogenes isolated from retail foods.

Listeria monocytogenes isolates recovered from retail ready-to-eat (RTE) meats, raw chickens and fresh produce were characterized by serogroup identification using PCR, genotyping using pulsed-field gel electrophoresis (PFGE) and antimicrobial susceptibility testing. Five L. monocytogenes serogroups were identified. Of the 167 isolates 68 (41%) belonged to serogroup 1/2b, 3b; 53 (32%) belonged ...
