Effect of low concentrations of lactic acid and temperature on the expression of adhesion, invasion, and toxin-encoding genes of from poultry.

Background And Objectives: The consumption of contaminated poultry meat is considered as a significant route of campylobacteriosis transmission. Lactic acid is a disinfectant agent with bactericidal effects on spp. The purpose of this study was to assess the low concentrations of lactic acid effect and different temperatures on the transcriptomic responses of adhesion and virulence-associated genes including and .

Addition of lime juice and NaCl to minced seafood may stimulate the expression of virulence, adhesion, and stress response genes.

is a ubiquitous opportunistic bacterium responsible for deadly listeriosis outbreaks. This pathogen has been recognized as a significant food-borne pathogen in seafood products. The present study aimed to investigate the transcript levels of virulence, adhesion, and stress response genes of .

Effect of Boiss. essential oil, NaCl, acid, time, and temperature on the growth of strains in broth and minced rainbow trout.

The small outbreaks of listeriosis as one of the leading causes of food poisoning-associated deaths occur more than previously reported. In current study, the growth ability of strains isolated from different sources of food and human origin was measured under salt stress (0.5%, 2.

Putative type II toxin-antitoxin systems in Listeria monocytogenes isolated from clinical, food, and animal samples in Iran.

Listeria monocytogenes is known as a major food-borne pathogen causing a severe life-threatening disease, listeriosis, in susceptible patients. This bacterium has special features that facilitate its survival in different conditions and cause resistance to antibacterial agents and biocides. Toxin-antitoxin (TA) system has a potential to be introduced as an antibacterial target because of its participation in cell physiology, including stress response, antiphage activity, biofilm formation, and resistance to antibiotics.

Antimicrobial resistance of Listeria monocytogenes isolated from seafood and humans in Iran.

Fourteen Listeria monocytogenes isolates previously collected from seafood (n = 7) and human patients (n = 7) were studied for their antimicrobial susceptibility against eight common antimicrobials (ampicillin, penicillin, gentamicin, streptomycin, tetracycline, trimethoprim-sulfamethoxazole, chloramphenicol, and cefotaxime). A high resistance level to ampicillin, cefotaxime (100%), and pencillin (57% in seafood isolates and 71.4% in clinical isolates) was observed in this study.
