Effects of intrinsic and extrinsic growth factors on virulence gene expression of foodborne pathogens in vitro and in food model systems; a review.

Since foodborne diseases are one of the major causes of human hospitalization and death, one of the main challenges to food safety is the elimination or reduction of pathogens from food products throughout the food production chain. Pathogens, such as species, , , species, , , species, etc., enter the consumer's body through the consumption of contaminated food and eventually cause disease, disability, and death in humans.

The sensory evaluation and antimicrobial efficacy of supernatant on in milk.

Postbiotics are metabolites derived from living probiotic bacteria like Lactobacillus strains, during the fermentation process and/or produced in pure form on laboratory scales. These compounds, depending on the type of probiotic from which they are prepared, have specific antibacterial agents such as: organic acids, bacteriocins, short-chain fatty acids, and peptides. The objective of this study was to investigate the effect of supernatant (LAS) on the growth pattern of at fluctuating temperatures and the sensory evaluation of milk that contains this probiotic.

Isolation of from an ocular infection and identification using ribosomal RNA gene: First case report from Iran.

Key Clinical Message: can cause infection in healthy people. As this bacterium is slow-growing, special attention should be paid to the timely diagnosis and control of its antibiotic resistance to prevent the spread of resistant strains.

Abstract: This study reports a case of ocular infection caused by and its treatment with various antibiotics.

A quantitative prevalence of O157 in different food samples using real-time qPCR method.

serogroup O157 is the main causative agent of several intestinal and extra-intestinal foodborne diseases in humans through consumption of low-dose contaminated foods such as milk, beef, and vegetables. To date, studies regarding the quantitative prevalence of O157 in foods are so limited. Therefore, this study aimed to evaluate the quantitative prevalence rate of serogroup O157 in raw milk ( = 144), vegetable salad ( = 174), and minced beef samples ( = 108) using the real-time qPCR SYBR green melting curve method targeting the gene.

Genetic diversity and antibiotic resistance of spp. isolates from food products.

The emergence of multidrug-resistant is a significant threat to global public health. Limited studies have investigated the incidence, antimicrobial susceptibility, and genetic diversity of isolated from food products. Conventional culture-based, serologic, molecular, disk diffusion, PCR, and RAPD-PCR methods were used to determine the prevalence rate, phenotypic and genotypic antibiotic resistance profile, and genetic diversity of the isolates from food samples including vegetable salad, ground meat, and raw cow's milk (405 samples).

Investigation of antimicrobial susceptibility and virulence factor genes in isolated from clinical mastitis cases of dairy cows.

is an opportunistic pathogen causing important diseases including mastitis and metritis in domestic animals such as dairy cows leading to prominent economic losses in food production industry. The aim of this study was to investigate bacterial species, antimicrobial susceptibility, and presence of virulence factor genes and genotyping of .  isolates associated with summer mastitis cases from 22 different farms around Tehran, Iran.

Genotypic and antimicrobial resistance characterizations of isolated from powdered milk infant formula: A comparison between domestic and imported products.

, an opportunistic foodborne pathogen and a main cause of meningitis in neonates, is usually isolated from powdered milk infant formula (PMIF). At the present study, were isolated from imported and domestically produced PMIF samples and identified by detection of gene using real-time PCR SYBR green melting curve following the evaluation of antimicrobial susceptibility and genotyping of the isolates employing BOX-PCR and RAPD methods. We detected totally 5% contamination rate and a significantly higher prevalence of in bulky imported domestically packaged PMIF samples.
