The characterization and correlation between the phenotypic and genotypic resistance of < em > Campylobacter < /em > spp < em > . < /em > isolates from commercial broilers and native chickens in the south of Thailand
Avian Pathol. 2023 Sep 18:1-49. doi: 10.1080/03079457.2023.2260322. Online ahead of print.ABSTRACTAbstractChicken is a major reservoir and source of human infections from zoonotic Campylobacter. In southern Thailand, chicken is the most popular meat consumed; however, little is known about the antimicrobial resistance (AMR) of Campylobacter spp. in chicken production systems. We aimed to investigate the prevalence and characteristics of AMR in Campylobacter isolates from commercial broiler and native chicken farms in southern Thailand. A total of 286 Campylobacter isolates (adjusted prevalence: 60.3%, SE ±0.01) were recov...

Prevalence of ciprofloxacin resistance and associated genetic determinants differed among Campylobacter isolated from human and poultry meat sources in Pennsylvania
Food Microbiol. 2023 Dec;116:104349. doi: 10.1016/j.fm.2023.104349. Epub 2023 Aug 3.ABSTRACTPoultry 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. Our goal was to assess potential differences in the prevalence o...

Distribution of Virulence Genes in < em > Campylobacter < /em > spp. Isolated from < em > Agaricus < /em > Mushrooms in Iran
In this study, 740 Agaricus mushroom samples were gathered randomly from various markets from June 2020 to December 2020. Confirmation of Campylobacter spp. using biochemical analyses and 23S rRNA-based PCR was performed. The agar dilution technique was used to determine resistance to antibiotics using gentamicin (GM10μg), ciprofloxacin (CIP5μg), nalidixic acid (NA30μg), tetracycline (TE30μg), ampicillin (AM10μg), amoxicillin+ clavulanic acid (AMC30μg), erythromycine (E15μg), azithromycin (AZM15μg), clindamycin (CC2μg), and chloramphenicol (C30μg). Multiplex PCR was utilized to determine the prevalence of the rec...

Antimicrobial resistance in < em > Campylobacter coli < /em > and < em > Campylobacter jejuni < /em > from human campylobacteriosis in Taiwan, 2016-2019
In conclusion, an extremely high proportion of C. coli (100%) and C. jejuni (88.3%) were multidrug-resistant and a high proportion (62.5%) of C. coli isolates had been resistant to azithromycin, erythromycin, and clindamycin that would complicate the treatment of invasive campylobacteriosis in this country.PMID:34748382 | DOI:10.1128/AAC.01736-21
