Abstract Campylobacter jejuni and C. coli are leading causes of human foodborne illness with poultry as a major vehicle. Turkeys are frequently colonized with Campylobacter but little is known about Campylobacter survival in turkey feces, even though fecal droppings are major vehicles for Campylobacter within-flock transmission as well as for environmental dissemination. Our objective was to examine survival of Campylobacter, including different strains, in freshly-excreted feces from naturally-colonized commercial turkey flocks and in suspensions of turkey feces in water from the turkey house. Fecal and water sus...

This study revealed that a diverse group of plasmids, carrying AR genes, are responsible for the phenotypic resistance seen in Salmonella isolated from United States food animals. It was also determined that many plasmids carry similar ARCs. Introduction Non-typhoidal Salmonella enterica is one of the most common causes of foodborne illnesses globally, with an estimated 1.2 million cases each year in the United States alone (CDC, 2013). Symptoms range from self-limiting gastrointestinal illness to sepsis. These infections can lead to death unless treated with antibiotics (Crump et al., 2015). Unfortunately, antimic...

This report describes the dynamics of FQ-associated mutations in the highly resistant in FQ mutants in S. Enteritidis. In addition, we characterized a deletion in the ramRA integenic region, demonstrating that this frequent mutation in the highly resistant FQ mutants provide resistance or reduce susceptibility to multiple families of antibiotics. Introduction Non-typhoidal Salmonella (NTS) is a major zoonotic pathogen worldwide (Bangtrakulnonth et al., 2004; Scallan et al., 2011). Infections caused by this pathogen have been mainly associated with gastroenteritis, an acute self-limiting intestinal infection. Howeve...

In this study, we determined the VAGs and antibiotic resistance profiles of APEC isolates recovered from colibacillosis affected broilers in Faisalabad region of Pakistan. A total of 84 diseased and dead birds from different local broilers farms were collected and examined for the gross lesions of colibacillosis by conducting postmortem examination. Of these, APEC isolates were recovered from 75 (89.2%) birds. Antibiotic susceptibility tests against 11 antimicrobial agents showed the highest resistance against ampicillin (98.6%) followed by tetracycline (97.3%) and ciprofloxacin (72%). The presence of 11 virulence-associat...

Abstract Atypical enteropathogenic Escherichia coli (aEPEC) strains (36 Japanese and 50 Bangladeshi) obtained from 649 poultry fecal samples were analyzed by molecular epidemiological methods. Clermont's phylogenetic typing showed that group A was more prevalent (58%, 50/86) than B1 (31%, 27/86). Intimin type β1, which is prevalent among human diarrheal patients, was predominant in both phylogroups B1 (81%, 22/27) and A (70%, 35/50). However, about 95% of B1-β1 strains belonged to virulence group I, and 77% of them were Japanese strains, while 17% (6/35) of A-β1 strains did. Multi-locus variable-num...

el S Abstract The pheno- and genotypic relatedness among Escherichia coli isolates from broilers with and without macroscopic lesions on the femoral head were investigated. In total, 219 isolates obtained from the bone marrow were characterized by serotyping, antimicrobial resistance profiles (AMR), phylogenetic grouping, detection of virulence-associated genes (VAG) and pulsed-field gel electrophoresis (PFGE). Serotyping revealed that 48.4% of the isolates were assigned to one of the three serotypes (O78:K80: 21.0%, O2:K1: 18.7%, O1:K1: 8.7%). Substantial phenotypic variation was also noticed in AMR testing as mo...
