Prevalence, Serotype, Antibiotic Susceptibility, and Genotype of Salmonella in Eggs From Poultry Farms and Marketplaces in Yangling, Shaanxi Province, China
Poultry products such as eggs provide essential nutrients to the human body and thus play vital roles in the human food network. Salmonella is one of the most notorious foodborne pathogens and has been found to be prevalent in eggs. To better understand the characteristics of Salmonella in eggs, we investigated the prevalence of Salmonella spp. in 814 fresh eggs collected from poultry farms and retail marketplaces in Yangling, Shaanxi Province, China. The serotype, genotype, and antibiotic susceptibilities of 61 Salmonella isolates recovered from the eggs were analyzed. The average detection rate of Salmonella-positive egg...

Isolation and characterization of a marine bacterium Vibrio diabolicus strain L2-2 capable of biotransforming sulfonamides.
In this study, a marine bacterium Vibrio diabolicus strain L2-2 was isolated which could metabolize 9 SAs to a different extent. Compared with SAs and their analogs, SAs with N-oxides of heterocyclic structure were easier to be transformed to their N4-acetylated metabolites or their isoxazole ring rearrangement isomers by strain L2-2. And, gene vdnatA and vdnatG were likely to be the key genes in SAs acetylation process, which might code Arylamine N-acetyltransferase. The biotransformation rates of sulfathiazole(STZ), sulfamonomethoxine(SMT), sulfadiazine(SDZ), sulfamethoxazole(SMX) and sulfisoxazole(SIX) could reach 29.39...

Supershed Escherichia coli O157:H7 Has Potential for Increased Persistence on the Rectoanal Junction Squamous Epithelial Cells and Antibiotic Resistance.
Authors: Mir RA, Brunelle BW, Alt DP, Arthur TM, Kudva IT
Abstract
Supershedding cattle shed Escherichia coli O157:H7 (O157) at ≥ 104 colony-forming units/g feces. We recently demonstrated that a supershed O157 (SS-O157) strain, SS-17, hyperadheres to the rectoanal junction (RAJ) squamous epithelial (RSE) cells which may contribute to SS-O157 persistence at this site in greater numbers, thereby increasing the fecal O157 load characterizing the supershedding phenomenon. In order to verify if this would be the signature adherence profile of any SS-O157, we tested additional SS-O157 isolates (n = 101; e...

Evaluation of Machine Learning Models for Predicting Antimicrobial Resistance of Actinobacillus pleuropneumoniae From Whole Genome Sequences
Antimicrobial resistance (AMR) is becoming a huge problem in countries all over the world, and new approaches to identifying strains resistant or susceptible to certain antibiotics are essential in fighting against antibiotic-resistant pathogens. Genotype-based machine learning methods showed great promise as a diagnostic tool, due to the increasing availability of genomic datasets and AST phenotypes. In this article, Support Vector Machine (SVM) and Set Covering Machine (SCM) models were used to learn and predict the resistance of the five drugs (Tetracycline, Ampicillin, Sulfisoxazole, Trimethoprim, and Enrofloxacin). Th...

Occurrence and risk assessment of antibiotics in multifunctional reservoirs in Dongguan, China.
Abstract
It is necessary to study the contamination of antibiotics in natural water bodies and assess its impact on ecological and human risks because of the large-scale use in the world. The occurrence and distribution characteristics of 45 antibiotics in reservoirs in Dongguan were investigated. Approximately, 77.8% of the detectable concentration of 35 antibiotics were found in the evaluation samples with concentration ranged from not detected (ND) to 729.59 ng/L, and dehydrated erythromycin was the highest one that appeared in Tongsha Reservoir. Fluoroquinolones and tetracyclines were the most abundan...

Diversity of Serotype, Genotype, and Antibiotic Susceptibility of Salmonella Prevalent in Pickled Ready-to-Eat Meat
Pickled ready-to-eat meat (PRTEM) is a meat product that is treated with various seasonings and then cooked. PRTEM is a popular food consumed mostly in China and some Asian countries. Since this food is considered ‘ready to eat’, once it is contaminated by foodborne pathogens such as Salmonella, the prospect for significant morbidity, mortality, and immeasurable economic losses can occur. Here we investigated the prevalence and concentration of Salmonella in 107 PRTEM samples collected from Shaanxi, China during 2015–2016. Furthermore, we analyzed the serotype, antibiotic susceptibility, and presence of antibiotic re...

Antimicrobial Resistance Genes, Cassettes, and Plasmids Present in Salmonella enterica Associated With United States Food Animals
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...

Shared Multidrug Resistance Patterns in Chicken-Associated Escherichia coli Identified by Association Rule Mining
In conclusion, association rule mining is an effective tool for identifying patterns of multidrug resistance within antimicrobial susceptibility testing data and evaluating the statistical and biological significance of the patterns. Rule quality measures used to sort and differentiate rules should be tested using resampling procedures to minimize the false discovery rate. Rule mining identified consistent multidrug resistance patterns involving beta-lactams, sulfisoxazole, tetracycline, gentamicin, and streptomycin in E. coli isolated from chicken carcasses and meat between 2004 and 2012. The generally low rule overlap su...

Occurrence of Transferable Integrons and sul and dfr Genes Among Sulfonamide-and/or Trimethoprim-Resistant Bacteria Isolated From Chilean Salmonid Farms
Conclusion
The present results demonstrated that Chilean salmon farms play an important role as reservoirs of sulfonamide- and trimethoprim-resistant bacteria. The prevalence of conjugative plasmids and integrons among sul-carrying bacteria suggests these bacteria, mainly belonging to the Pseudomonas genus may contribute to high spread of bacterial resistance to sulfonamides and other antibacterials in environments associated with Chilean salmon farms. This is the first study reporting the occurrence of transferable sul and dfr genes and integrons among the antimicrobial resistant bacteria associated with Chilean salmonid...
