The genes associated with antimicrobial resistance in <i>Campylobacter</i> spp. are poorly understood. To address this knowledge gap, we conducted a prevalence survey of AMR <i>Campylobacter</i> across 84 chicken farms in two districts of Bangladesh. Pooled cloacal swabs were collected from chickens and underwent bacteriological testing for <i>Campylobacter</i> spp. with PCR confirmation. Antimicrobial susceptibility was tested against 14 antibiotics by disk diffusion method, and 12 resistance genes were screened in <i>Campylobacter</i>-positive isolates using multiplex PCR. A total of 34 (40.5%) farms were <i>Campylobacter</i>-positive of which 73.5% of isolates were resistant to at least 10 antibiotics. The antimicrobial susceptibility results indicate a high level of resistance against streptomycin (97.1%), clindamycin (97.1%), ampicillin (94.1%), tetracycline (94.1%), erythromycin (91.2%), ciprofloxacin (88.2%), nalidixic acid (85.3%), and imipenem (82.4%), and comparatively a low frequency of resistance to chloramphenicol (47.1%), ceftazidime (44.1%), and colistin (35.3%).

Prompt, appropriate antibiotic treatment is essential to save lives. We aimed to investigate antibiotic selection and listeriosis knowledge among health care providers. We first performed a retrospective study on patients with listeriosis who were treated in a hospital in China from January 2013 to March 2023. Patient characteristics and antibiotic selections were recorded. Antibiotics were classified as effective or ineffective based on the efficacy classifications listed in <i>The Sanford Guide to Antimicrobial Therapy</i> (50<sup>th</sup> edition). We then conducted a questionnaire survey of health care providers to investigate their listeriosis knowledge and practices between April 2023 to May 2023. Fifteen listeriosis patients were identified, with a case fatality rate of 26.7% (4/15). Empirical treatments assessed as effective antibiotics or ineffective antibiotics were given to 33.3% (5/15) and 66.7% (10/15) of the patients, respectively. After <i>Listeria monocytogenes</i> was identified, 40% (6/15) of the patients received an adjustment to their antibiotics, although 50% (3/6) patients still received ineffective antibiotics. The questionnaire survey of 77 participating health care providers showed that 32.9% (24/73) of the clinicians were unaware of the appropriate antibiotics for listeriosis. Most participants (83.1%, 64/77) would read the drug sensitivity report before selecting the antibiotics. The selection of effective antibiotics differed between the infectious diseases department and other departments (<i>p</i> < 0.001), but did not differ between junior title and other titles (<i>p</i> = 0.088). Most patients with listeriosis did not receive appropriate antibiotics, which might have accounted for the high fatality rate, and may have resulted from inadequate listeriosis knowledge. More education and correct reporting of drug sensitivity results are urgently needed.</p>","PeriodicalId":12333,"journal":{"name":"Foodborne pathogens and disease","volume":" ","pages":""},"PeriodicalIF":1.9,"publicationDate":"2025-01-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142947051","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
