Summary: This study investigated the prevalence and antibiotic resistance of Campylobacter in local Chinese dual-purpose chickens. The dominant clonal complexes of C. jejuni and C. coli were identified, and C. coli exhibited a higher antibiotic resistance rate than C. jejuni. Whole-genome sequencing detected multiple antibiotic resistance genes, but the correlation between genes and resistance phenotypes was weak for most antibiotics. Additionally, virulence gene analysis revealed differences between C. jejuni and C. coli in genes related to adhesion, colonization, and invasion.

Summary: This study confirms a high prevalence of Campylobacter coli in chicken meat sold in traditional markets and supermarkets in Lima, Peru. Phenotypic resistance to tetracyclines was observed in more than 70% of these strains, which may be linked with the expression of the Tet(O) gene.

Summary: In a four-year active surveillance study at four metropolitan hospitals in Michigan, an increasing trend in Campylobacter jejuni infections was observed. Analysis of 214 C. jejuni isolates revealed widespread antibiotic resistance, with differences in infection rates by hospital type and patient characteristics associated with disease severity.

Summary: This study investigated the prevalence and antimicrobial resistance patterns of Campylobacter spp. on chicken samples purchased from 50 local wet markets and supermarkets in central Thailand. High contamination rates and alarming levels of antimicrobial resistance were found in Campylobacter spp. isolated from retail chicken samples in Thailand, highlighting the necessity of interventions to reduce its prevalence in the country.

Summary: This study isolated and characterized Campylobacter spp. from chickens in Mongolia, finding resistance to multiple antibiotics. Some C. jejuni/C. coli isolates were resistant to nalidixic acid and fluoroquinolones, with specific genetic mechanisms for resistance identified. Multilocus sequence typing and phylogenetic analyses revealed genetic variation and potential links to other countries. This study represents the first report on antimicrobial resistance of Campylobacter spp. in farm animals in Mongolia, providing valuable insights for antibiotic use in this region.

Summary: Antibiotic tolerance in C. jejuni leads to the development of antibiotic resistance, particularly fluoroquinolone resistance. Exposure to ciprofloxacin or tetracycline induces antibiotic tolerance and promotes the emergence of fluoroquinolone-resistant C. jejuni clones. Alkyl hydroperoxide reductase plays a critical role in reducing the development of fluoroquinolone resistance after tolerance induction.

Summary: Campylobacter is the leading bacterial cause of diarrheal disease worldwide and poultry is the primary vehicle of its transmission to humans. The study found Campylobacter in meat samples from conventionally reared and free-range broilers, with 72.7% detection rate in backyard chickens. Most Campylobacter isolates showed resistance to antibiotics, with 97.7% classified as multidrug resistant.

Summary: The study assessed the efficacy of two field-isolated bacteriophages against an antimicrobial-resistant Campylobacter jejuni strain in experimental infections. A two-step phage application successfully reduced the Campylobacter load in broilers, showcasing the potential of phage therapy in controlling Campylobacter in poultry.

Summary: Antibiotic growth promoters (AGPs) have been widely used in animal feed to improve efficiency, but their use has led to antibiotic-resistant pathogens and posed a threat to food safety and public health. China banned the use of AGPs in animal feed from 2020, but the effects of this ban on foodborne pathogens and antibiotic resistance have not been fully understood. This study found that after the ban, the isolation rate of Campylobacter, a foodborne pathogen, slightly increased and there was a significant increase in antibiotic resistance and virulence genes. It also showed the potential transmission of antibiotic-resistant Campylobacter from pigs to humans.

Summary: Brucellosis is a neglected zoonosis that affects animals and people in the underdeveloped world. This study aimed to isolate and identify Brucella species from faeces of sero positive cattle in Punjab, India. Fourteen Brucella species were isolated, with 11 identified as Brucella abortus and 3 identified as Brucella melitensis. The study highlights the potential risk of animal faeces for animal and human health and emphasizes the need for careful handling of faeces from seropositive cattle.

Summary: The study revealed that Streptococcus equi subsp. zooepidemicus rapidly disseminated in various organs of pigs following oronasal inoculation, with tonsil samples consistently harboring the pathogen throughout the study period. The varying bacterial loads in mesenteric lymph nodes indicated persistence, replication, and a potential source for shedding.
