  1. Cold Tolerance in Campylobacter jejuni and its Impact on Food Safety

    • Food Research International
    • Campylobacter jejuni is a major cause of foodborne illnesses worldwide and is primarily transmitted to humans through contaminated poultry meat. To control this pathogen, it is critical to understand its cold tolerance because poultry products are usually distributed in the cold chain. However, there is limited information regarding how this thermotolerant, microaerophilic pathogen can survive in cold and aerobic environments in the poultry cold chain.

  2. Genotypic characterization, antimicrobial susceptibility and virulence determinants of Campylobacter jejuni and Campylobacter coli isolated from pastured poultry farms

    • Frontiers in Microbiology
    • Aim  Campylobacter is the leading bacterial pathogen that causes foodborne illnesses worldwide. Pasture farming is regarded as an important source of agricultural production for small farming communities. Consumer preference for pasture-raised animal products has increased; however, there is a paucity of information on the microbiological quality of pasture-raised poultry products.

  3. Seasonal variation in the prevalence and antimicrobial resistance of Campylobacter species in milk and milk products in Ethiopia

    • International Dairy Journal
    • Seasonal variation in the prevalence and antimicrobial resistance of Campylobacter species in the Ethiopian dairy value chain was investigated. Dairy food samples (456) were collected in the dry and wet seasons in three regions of Ethiopia. Campylobacter species were detected in 20% of samples collected in the wet season. The overall prevalence did not differ significantly between the wet and dry seasons.

  4. 281 Effects of Corynebacterium Glutamicum Cell Mass Supplementation on Modulation of Mucosa-Associated Microbiota to Intestinal Health of Nursery Pigs

    • Journal of Animal Science
    • The objectives were to evaluate the effects of Corynebacterium glutamicum cell mass (CGCM) supplementation, replacing blood plasma in diets, on the gene expressions of biomarkers associated with peptidoglycan and their correlation with intestinal health in nursery pigs. Weaned pigs (n = 32) were allotted to 4 dietary treatments based on the randomized complete block design with initial BW as blocks.

  6. A comprehensive review of the applications of bacteriophage-derived endolysins for foodborne bacterial pathogens and food safety: recent advances, challenges, and future perspective

    • Frontiers in Microbiology
    • Foodborne diseases are caused by food contaminated by pathogenic bacteria such as Escherichia coli, Salmonella, Staphylococcus aureus, Listeria monocytogenes, Campylobacter, and Clostridium, a critical threat to human health. As a novel antibacterial agent against foodborne pathogens, endolysins are peptidoglycan hydrolases encoded by bacteriophages that lyse bacterial cells by targeting their cell wall, notably in Gram-positive bacteria due to their naturally exposed peptidoglycan layer.

  7. Fecal Microbiota Transplantation Reduces Campylobacter jejuni Colonization in Young Broiler Chickens Challenged by Oral Gavage but Not by Seeder Birds

    • Antibiotics
    • Campylobacter spp., particularly C. jejuni and C. coli, are major food safety concerns, transmitted to humans mainly via contaminated poultry meat. In a previous study, we found that some commercial broiler farms consistently produced Campylobacter-free flocks while others consistently reared Campylobacter-colonized flocks, and significant differences in the gut microbiota compositions between the two types of farm categories were revealed.

  8. Campylobacter jejuni Outbreak Linked to Raw Oysters in Rhode Island, 2021

    • Journal of Food Protection
    • Oysters and other shellfish are not a food that is commonly highlighted as high risk for Campylobacter contamination. The Rhode Island Department of Health (RIDOH) conducted a multiagency investigation of a Campylobacter jejuni outbreak that was linked to the consumption of raw oysters; the first such outbreak detected in Rhode Island. The environmental investigation identified birds as the likely source of contamination of the aquacultured oysters.

    • Frontiers in Microbiology
    • In recent years, there has been an unprecedented advancement in in situ analytical approaches that contribute to the mechanistic understanding of microbial communities by explicitly incorporating ecology and studying their assembly. In this study, we have analyzed the temporal profiles of the healthy broiler cecal microbiome from day 3 to day 35 to recover the stable and varying components of microbial communities.

  14. Genetic characteristics, antimicrobial susceptibility, and virulence genes distribution of Campylobacter isolated from local dual-purpose chickens in central China

    • Frontiers in Cellular and Infection Microbiology
    • Food-borne antibiotic-resistant Campylobacter poses a serious threat to public health. To understand the prevalence and genetic characteristics of Campylobacter in Chinese local dual-purpose (meat and eggs) chickens, the genomes of 30 Campylobacter isolates, including 13 C. jejuni and 17 C. coli from Jianghan-chickens in central China, were sequenced and tested for antibiotic susceptibility. The results showed that CC-354 and CC-828 were the dominant clonal complexes of C. jejuni and C.

    • Journal of the Science of Food and Agriculture
    • Abstract Background Mycoplasma hyorhinis is a prevalent respiratory pathogen in swine, causing significant economic loss to pig producers. There is growing evidence that respiratory pathogen infections have a large impact on intestinal microecology. To study the effect of M. hyorhinis infection on gut microbial composition and metabolome profile, pigs were infected with M. hyorhinis.

  17. A comparison of European surveillance programs for campylobacter in broilers

    • Food Control
    • Campylobacter is an important foodborne pathogen as it is associated with significant disease burden across Europe. Among various sources, Campylobacter infections in humans are often related to the consumption of undercooked poultry meat or improper handling of poultry meat. Many European countries have implemented measures to reduce human exposure to Campylobacter from broiler meat.

    • Route of contamination of raw milk and dairy products by Campylobacter spp., methods of detection and advantages of viability qPCR application to dairy matrices. The aim of this study was to investigate the survival of Campylobacter jejuni in dairy matrices by viability qPCR.

  20. Prevalence of ciprofloxacin resistance and associated genetic determinants differed among Campylobacter isolated from human and poultry meat sources in Pennsylvania

    • Food Microbiology
    • Poultry is the primary source of Campylobacter infections and severe campylobacteriosis cases are treated with macrolides and fluoroquinolones. However, these drugs are less effective against antimicrobial resistant strains. Here, we investigated the prevalence of phenotypic antimicrobial resistance and associated resistance genetic determinants in Campylobacter isolates collected from human clinical (N = 123) and meat (N = 80) sources in Pennsylvania in 2017 and 2018.

    • Frontiers in Microbiology
    • Campylobacter jejuni is the most frequent cause of bacterial gastroenteritis; therefore, the characteristics of its epidemiology must be continuously investigated to support possible mitigating measures. This is particularly important when evaluating representative strains from the world's leading chicken meat exporter, Brazil. We evaluated a panel of 14 virulence genes in 359 strains of C. jejuni isolated from chilled broiler carcasses in Brazil.

    • Frontiers in Microbiology
    • Introduction

      Lactobacilli may prevent broilers from colonization with Campylobacter spp. and other gram-negative zoonotic bacteria through lactic acid production and modulation of the intestinal microbiota. This study evaluated the effects of daily intake of Lactiplantibacillus plantarum 256 (LP256) on Campylobacter jejuni (C. jejuni) loads in ceca and feces of C. jejuni challenged broilers, together with the changes in the gut microbiota.

  23. Quantitative microbiological risk assessment model for Campylobacter in raw milk of dairy cows in Germany

    • Microbial Risk Analysis
    • The consumer demand for raw milk from dairy cows has increased and local sales via vending machines have been intensified. Therefore, this study aimed to assess the risk associated with the consumption of unboiled raw milk contaminated with Campylobacter by estimating the number of campylobacteriosis cases. For this a stochastic quantitative microbial risk assessment (QMRA) model was developed that covered the whole supply chain.
