Summary: Poultry is a rapidly growing industry, but concerns about food safety and the presence of bacteria like Campylobacter in poultry remain. The discovery of new antimicrobials, such as eugenol, is important for ensuring the safety of poultry meat. However, further research is needed to determine the specific applications and effectiveness of eugenol as a food preservative in poultry meat safety.

Summary: It is well-established that raw or incompletely thermally processed poultry meat is a major source of strong-evidence foodborne outbreaks of human campylobacteriosis. The dominant species of Campylobacter in chicken meat samples has traditionally been C. jejuni, but recently, C. coli has been increasingly recovered from chicken meat to the extent that it often comprises the majority of identified campylobacters. This review provides a detailed analysis of the changing prevalence of C. jejuni and C. coli in chicken meat, as well as the factors influencing their distribution.

Summary: RNA-seq was used to analyze the differentially expressed genes (DEGs) in C. coli HC2-48 and C. jejuni OD2-67 transcriptomes under different temperature conditions. In C. coli HC2-48, genes involved in flagellar assembly were significantly impacted by low temperatures (4°C), while genes related to the ribosome and ribonucleoprotein complex were modulated in C. jejuni OD2-67 at 4°C. Although more DEGs were observed in the chicken juice medium compared to Mueller-Hinton broth, there were no common genes expressed at all incubation times, indicating that the food matrix environment is not the sole determinant of differential expression in Campylobacter spp. at low temperatures.

Summary: This study provides the first whole-genome sequencing analysis of Campylobacter isolated from Lebanon. The results show multidrug resistance and virulence determinants in the isolate, emphasizing the need to study the burden of Campylobacter in Lebanon and the Middle East and North Africa region.

Summary: Campylobacter jejuni infection linked to contaminated poultry products is a leading cause of human enteric illness worldwide. Vaccination of chickens is a potential strategy to control C. jejuni colonization, but identifying the most effective formulation remains a challenge due to variability in reported vaccine efficacies. A systematic review comparing C. jejuni vaccine studies found total outer membrane proteins and cysteine ABC transporter substrate-binding protein to be among the most efficacious vaccine antigen candidates, highlighting the need for increased consistency in study design and reporting in poultry to enable robust comparisons of vaccine candidates.

Summary: In this retrospective, multicenter study, the clinical characteristics of Campylobacter bacteremia in western Japan were investigated. The study revealed that nearly half of the patients presented with fever as the main symptom, rather than gastrointestinal symptoms.

Summary: This study developed a triplex qPCR assay for the detection and quantification of Campylobacter species in wastewater samples, specifically targeting C. jejuni and C. coli. The assay demonstrated high sensitivity and reliability, and can be used for long-term monitoring of Campylobacter prevalence in communities and surrounding environments.

Summary: This study aimed to compare the characteristics of Campylobacter jejuni strains causing bloodstream infection (BSI) with those causing enteritis (En). The study found that the predominant strain in BSI cases was ST-4526, and the overall distribution of sequence types was similar in both BSI and En strains. Differences in CPS type distribution might be related to the pathogenesis of bacteremia.

Summary: Campylobacter jejuni and C. coli are major causes of gastrointestinal illnesses transmitted to humans mainly through chicken meats. This study examined the levels of bacterial contamination in retail chicken meats in Japan and found that 45.7% of the samples were positive, with 8.4% exceeding the safe limit. Bacterial counts were higher in fall compared to spring and summer, and younger slaughtered chickens were more contaminated. The study also identified antimicrobial resistance genes and clonal complexes of C. jejuni isolates.

Summary: The study investigated trends in antimicrobial resistance in Campylobacter jejuni and Campylobacter coli in poultry in Germany between 2010 and 2016, finding higher resistance in C. coli than in C. jejuni, and higher resistance in turkeys than in broilers. Resistance was highest to tetracycline and (fluoro)quinolones, with lower resistance to gentamicin and erythromycin. While resistance to tetracycline and erythromycin decreased over time, resistance to (fluoro)quinolones increased. An association between antimicrobial use and resistance was observed for tetracycline and erythromycin, but not for aminoglycosides. Nalidixic acid and ciprofloxacin resistance increased despite a decrease in fluoroquinolone use, suggesting other factors influencing resistance to (fluoro)quinolones in Campylobacter.

Summary: The study revealed genetically related Campylobacter populations in different environments within integrated broiler companies, suggesting that particular factors or management practices may play a role in the dispersion or carry-over of Campylobacter in the studied broiler companies.

Summary: This study assessed the ability of C. jejuni and C. coli strains isolated from diseased poultry to form biofilm. The results showed that C. jejuni strains were classified as no, weak, and moderate biofilm producers, while all C. coli strains were weak producers. Genes involved in chemotaxis, adhesion, and invasion were present in all C. jejuni strains. Further investigations are needed to better understand the genetic determinants involved in extra-intestinal Campylobacter biofilm formation.

Summary: This study aimed to estimate the prevalence of Campylobacter in chicken carcasses from slaughterhouses in three states in southern Brazil, revealing a prevalence of 35.84% with C. jejuni being the main species. While the size of slaughterhouses did not affect the prevalence, significant differences were observed among the three states, with Parana having the lowest prevalence. The results highlight the need for strategies to control this pathogen in Brazil to protect consumer health and maintain the country's position in the international poultry meat market.
