Summary: The study showed that there were statistically significant but minor differences in beta diversity among study participants during the challenge period, and pre-challenge alpha diversity was higher in participants who did not develop campylobacteriosis compared to those who did. However, alpha diversity decreased in all participants after infection. Future studies could explore CHIM studies with inocula more closely resembling natural exposure and field studies involving naturally-occurring enteric infections.

Summary: Thirteen pathogenic Campylobacter strains were isolated from diarrhea cases and raw poultry meat products in Huzhou, including 11 Campylobacter jejuni and 2 Campylobacter coli strains. These strains contain multiple virulence-related genes and show high resistance to nalidixic acid, ciprofloxacin, and tetracycline. Genomic sequencing revealed the presence of tet(O) and blaOXA resistance genes in all C. jejuni strains and multiple drug resistance genes in 2 C. coli strains.

Summary: This study conducted a classification and frequency analysis of LOS genotypes in C. jejuni and C. coli. The results showed that class B is the most abundant LOS class in C. jejuni, while class III is the most abundant LOS locus type in C. coli.

Summary: We report the first case of vertebral osteomyelitis caused by C. lari, identified from a vertebral biopsy sample collected using CT-guided percutaneous needle biopsy in a patient without obvious episodes of immunodeficiency. Pathogen identification was aided by cultureing using the HK semisolid medium. It is crucial to identify the causative pathogen in vertebral osteomyelitis.

Summary: The development and validation of a novel mechanistic dose-response model for Campylobacter jejuni in this study provides insights into the dynamics of infection probability, considering factors such as food types and host age. The predictive framework demonstrates high accuracy in estimating dose for a certain infection probability compared to previously reported relationships, showing the importance of food type and host age in dose-response dynamics.

Summary: The COVID-19 pandemic had a more adverse impact on laboratory reporting of norovirus compared to Campylobacter in England. This may be explained by stronger behavioral interventions affecting norovirus transmission and a greater reduction in norovirus testing capacity. The study highlights the differential impact a pandemic can have on surveillance of gastrointestinal infectious diseases.

Summary: This study aimed to determine the microbial kinetic parameters in chicken under dynamic temperature for campylobacteriosis strains in New Zealand. The obtained D and z values were consistent with international isothermal data, indicating that the high rate of campylobacteriosis in New Zealand is not due to the emergence of more heat resistant strains.

Summary: Campylobacter is the most common bacterial cause of gastrointestinal disease, and contaminated poultry is often the source of infection. This study examines the survivability and virulence potential of sublethally injured Campylobacter in mice, following exposure to commonly used chemicals in poultry meat processing. The results show that sublethally injured Campylobacter jejuni has reduced virulence and colonization potential in mice.

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: 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: Campylobacter is considered to be one of the main causes of diarrhoeal diseases globally, mainly transmitted through food, especially poultry meat. Recent studies have suggested the use of air sampling for detection in broiler houses and molecular detection methods. However, a major limitation of these methods is the inability to differentiate between alive and dead cells.

Summary: The Lavandula preparations studied in this research showed promising antibiofilm properties against Campylobacter jejuni, with potential for developing new agents to combat bacterial biofilm formation. Transcriptome analysis confirmed the effects of Lavandula essential oil on C. jejuni biofilm properties, highlighting the importance of innovative approaches and alternative strategies in the field of biofilm research.
