Evaluating Campylobacter spp at the human-wildlife interface
Campylobacter spp. infections are an increasing global concern responsible for a significant burden of disease every year. Wildlife and domestic animals are considered important reservoirs, but little is known about host-factors driving pathogen infection dynamics in wild mammal populations. In …

Study on the presence of Campylobacter spp. along the poultry food chain
… esta tesis tiene como objetivo el estudio de Campylobacter spp. a lo largo de la cadena alimentaria de la carne de pollo, desde la granja hasta el consumidor. Los resultados han mostrado altas prevalencias; 42,9 % (otoño) y 30,8 % (primavera) en granjas, 48,2 % en matadero y 39,4 % en …

Campylobacter spp. within the UK poultry industry: prevalence, risk factors and the chicken microbiome
Campylobacteriosis as a disease, is of huge significance to the human population worldwide. It remains the number one cause of human zoonosis within the EU with over 245,000 cases of campylobacteriosis reported in 2018 with many more cases thought to have gone unreported. Campylobacter is of …

Association of Campylobacter spp. Levels between Chicken Grow-Out Environmental Samples and Processed Carcasses
Campylobacter spp. have been isolated from live poultry, production environment, processing facility, and raw poultry products. The detection of Campylobacter using both quantitative and qualitative techniques would provide a more accurate assessment of pre- or post harvest contamination. …

Development and use of a chemically defined medium for estimating the oxygen tolerance of campylobacter species
When estimating the degree of oxygen tolerance of Campylobacter spp. on Brucella medium, the brand of tryptone (pancreatic digest of casein) used in the medium greatly influenced the results. In fact, with some brands and batches of tryptone, C. jejuni could grow at 21 % O₂ without any additional …

Isolation, growth and epidemiology of campylobacter jejuni / coli
… metabisulphite (0.05%) gave slightly fewer Campylobacter isolations than the SEES when evaluated with various types of specimens and was also less selective. Maximum isolation rates were achieved by incubating broths at 42 0C and subculturing after 24h and 42h. Growth studies of three …

Efficacy of Delmopinol in Preventing the Attachment of Campylobacter jejuni to Chicken, Stainless Steel and High-Density Polyethylene
Campylobacter spp. are the second leading bacterial cause of food borne illness in the U.S. New antimicrobials that prevent bacterial attachment may be effective for reducing Campylobacter. Delmopinol hydrochloride (delmopinol) is a cationic surfactant that is effective for treating and preventing …

Genotyping antibiotic resistance properties of escherichia coli and campylobacter jejuni associated with diarrhoea in young children in the Vhembe District
… pathogens such as Escherichia coli (E. coli) and Campylobacter spp. is increasing, surveillance of antimicrobial resistance genes (ARG) is limited in Africa. The need for such studies in Africa was demonstrated by our published review of the literature on surveillance of molecular resistance …

The involvement of bacteria in the progression of Barrett’s oesophagus to adenocarcinoma of the oesophagus
… such as Peptostreptococcus were identified. Campylobacter spp. were isolated from 75%, 50% and 60% of GORD, BO and ADC patients, respectively, compared with 20% of controls. Helicobacter pylori, which has been proposed to be protective in oesophageal disease, was significantly reduced in …

Development and validation of a CRISPR interference system for gene regulation in Campylobacter jejuni
Campylobacter spp. are the leading cause of bacterial food-borne illness in humans worldwide, with Campylobacter jejuni responsible for 80% of these infections. There is an urgent need to understand fundamental C. jejuni biology for the development of new strategies to prevent and treat infections. …

Feed Supplementation with Natural Extracts of Cranberry and its Efficacy on Campylobacter Colonization in Poultry
<p>Campylobacter spp. has been identified as one of the leading causative agents of food borne diarrheal illness. Epidemiological evidence has shown that poultry is the main source for human infection. Poultry are asymptomatic carriers of Campylobacter within their gastrointestinal tract, with …

Effects of phytogenics on intestinal pathogenic bacteria and microbiota of non-ruminants
… antibacterial activity was demonstrated against Campylobacter jejuni, Listeria monocytogenes, Escherichia coli and Salmonella enterica subsp. enterica serovar Enteritidis. Agrimonia pilosa Ledeb, Smilax glabra Roxb, Anemone chinensis Bunge, and Iris domestica (L.) Goldblatt and Mabb were found to …
