Zoonoses and Public Health, EarlyView. Campylobacter is a major cause of food poisoning and is typically the most common cause of gastroenteritis in the UK. Data collected at broiler farm and abattoir level, for slaughter batches that were sampled for UK-wide monitoring, were used to generate two epidemiological risk factor models.

The main goal of the present study was to evaluate the influence of thermal exposure on Vibrio population and HSP genes expression (HSP 90, HSP70, and HSP20) in rayed pearl oyster (P. radiata). To this end, the oysters were reared for 30 days at temperatures of 22 °C (control), 25 °C, 27 °C, and 29 °C. The results showed that five dominate Vibrio strains including Vibrio hepatarius, V. harveyi, V.

The objective of this study is to explore the antibacterial action modes and virulence-inhibitory effects of allyl isothiocyanate (AITC) against Clostridium perfringens (C. perfringens). The minimum inhibitory concentration (MIC) of AITC against vegetative cells of Cp 13124 was 0.1 μL/mL, and the time-kill kinetics analysis revealed that AITC could significantly suppress the growth of Cp 13124.

Journal of Food Safety, EarlyView. Cross-contamination in the poultry slaughtering process can lead to thespread of zoonotic bacteria like Salmonellaenterica. Surfaces of equiptment may facilitate contamination of carcasses due to bacterial adherence and transfer.

Salmonella is a major cause of food poisoning, and its infection and antimicrobial resistance vary regionally due to different sanitary standards and the use of antimicrobials. The aim of this study is to evaluate the microbiological contamination and antimicrobial resistance of Salmonella in Shanghai, providing references for supervision over food safety and clinical treatment.

Potential single nucleotide polymorphisms (SNPs) were detected between two chicken breeds (Kashmir favorella and broiler) using deep RNA sequencing. This was carried out to comprehend the coding area alterations, which cause variances in the immunological response to Salmonella infection. In the present study, we identified high impact SNPs from both chicken breeds in order to delineate different pathways that mediate disease resistant/susceptibility traits.

Salmonella spp., one of the most frequently reported bacteria, causes foodborne illness and economic losses. Due to the threat of increasing antibiotic resistant foodborne pathogens, application of bacteriophages as novel antibacterial agents in food matrices has become an emerging strategy. In this study, a novel Salmonella phage PS3-1 with high lytic activity against Salmonella Typhimurium was identified from previously isolated phages.

Resistance to antibacterial agents is a growing global public health problem that reduces the efficacy of available antibacterial agents, leading to increased patient mortality and morbidity. Unfortunately, only 16 antibacterial drugs have been approved by the FDA in the last 10 years, so it is necessary to develop new agents with novel chemical structures and/or mechanisms of action.

The co-existence of the colistin resistance (mcr) gene with multiple drug-resistance genes has raised concerns about the possibility of the development of pan-drug-resistant bacteria that will complicate treatment. This study aimed to investigate the antibiotic resistance profiles and co-existence of antibiotic resistance genes among the colistin-resistant Enterobacteriaceae isolates recovered from poultry and poultry meats.

Salmonellosis, a zoonotic disease, is one of the leading causes of foodborne illness worldwide. It is responsible for most infections caused by consumption of contaminated food. In recent years, a significant ...

In 2016, the U.S. Food and Drug Administration (FDA), the Centers for Disease Control and Prevention (CDC), and state partners investigated nine Listeria monocytogenes infections linked to frozen vegetables. The investigation began with two environmental L.

Staphylococcus aureus is one of the ESKAPE (Enterococcus faecium, Staphylococcus aureus, Klebsiella pneumoniae, Acinetobacter baumannii, Pseudomonas aeruginosa, and Enterobacter species) pathogens among which multidrug resistance has emerged. Resistance to methicillin has resulted in clinicians using the antibiotic of last resort, vancomycin, to treat infections caused by methicillin-resistant S. aureus (MRSA).

Salmonella 4,[5],12:i:-, a monophasic variant of S. Typhimurium, has become a global serovar causing animal and human infections since its first emergence in the late 1980's. Several previous studies showed the increasing prevalence of S. 4,[5],12:i:- in China, most of which were from swine with multidrug resistance (MDR) profiles. However, the molecular characteristic and evolution of S. 4,[5],12:i:- in the same swine farm are still unknown. In this study, a total of 54 S.

Gannan navel orange is a famous brand in China but the isolation of its endophytic fungi was rarely reported. In this study, a total of 54 strains of endophytic fungi were successfully isolated from the pulp, peel, twig, and leaf of Gannan navel orange; they were successfully identified to belong to 17 species of 12 genera. All these strains were fermented using potato-dextrose agar (PDA) medium, and their secondary metabolites were then extracted with ethyl acetate (EtOAc).

Organic fertilizers can partially replace chemical fertilizers to improve agricultural production and reduce negative environmental impacts.

The development of rapid and effective detection of pathogens is necessary to prevent bacterial infection. Herein, we constructed a novel polymerase chain reaction-dynamic light scattering (PCR-DLS) sensing assay for detecting Salmonella sensitively.

Climate change is one of the most important threats to farmed abalone worldwide. Although abalone is more susceptible to vibriosis at higher water temperatures, the molecular mode of action underlying this has not been fully elucidated. Therefore, this study aimed to address the high susceptibility of Halitotis discus hannai to V.

Journal of the Science of Food and Agriculture, Accepted Article. BACKGROUND Bacillus licheniformis (B. licheniformis) is a gram-positive bacterium that has strong environmental adaptability and can improve the growth performance, immunity, and antioxidant function of broilers. The current study aimed to elucidate the protective capability of B.

Journal of Food Safety, EarlyView. Salmonella enteric serovar Typhimurium is one of the causative agents for non-typhoidal salmonellosis which is highly associated with the consumption animal products such as eggs, pork, and poultry. Phytochemicals present in plant extracts were reported to improve food safety by inhibiting the growth of foodborne pathogens.

International Journal of Food Science &Technology, Accepted Article. In African public health systems, Listeria monocytogenes is a pathogen of relatively low priority. Yet, the biggest listeriosis outbreak recorded to date occurred in Africa in 2018. This review highlights the factors that potentially impact L. monocytogenes transmission risks through African food value chains (FVCs).

Clarifying mechanisms underlying the selective adhesion of probiotics and competitive exclusion of pathogens in the intestine is a central theme for shrimp health.

Variation exists in milk protein concentration of dairy cows of the same breed that are fed and managed in the same environment, and little information was available on this variation which might be attributed to differences in rumen microbial composition as well as their fermentation metabolites.
