Interplay of antibiotic resistance and food-associated stress tolerance in foodborne pathogens

Publication date: Available online 16 November 2019Source: Trends in Food Science &TechnologyAuthor(s): Xinyu Liao, Yanna Ma, Eric Banan-Mwine Daliri, Shigenobu Koseki, Shuai Wei, Donghong Liu, Xingqian Ye, Shiguo Chen, Tian DingAbstractBackgroundThe discovery and use of antibiotics have produced tremendous benefits for human society, however, with the large-scale use of antibiotics in medicine, animal husbandry and other fields, more and more antibiotic-resistant bacteria have emerged. Since diseases caused by such antibiotic resistant bacteria could require more drastic measures to treat, the emergence of such resistant bacteria in food has attracted much concern.Scope and approachIn this review, we summarized the interplay between antibiotic resistance and food-associated stress tolerance, and the hypothesized molecular mechanisms for the cross protection in bacteria.Key findings and conclusionsIn this review, we found that some common food-associated stresses, such as cold, acid, osmosis and sanitizers could provide cross protection for bacteria against antibiotics. In turn, antibiotic resistance could also render bacteria more tolerant to food-associated stresses. Meanwhile, novel nonthermal technologies may more likely result in little or no difference in bacterial antibiotic resistance, and this can be an advantage over traditional sterilization methods. Several molecular mechanisms for the cross protection between antibiotics and food-associated stresses have been...

The objective of this study was to estimate AMU in a broiler chicken farm in Pakistan over a five-year period and to extrapolate national AMU in commercial broiler farming. Between 2013 and 2017, we monitored AMU in 30 flocks from a commercial broiler farm in Punjab, the most populous province of Pakistan. The amount of antimicrobials administered was calculated in milligram/population unit of the final flock weight (mg/fPU) and in used daily dose (UDD). The annual on-farm antimicrobial use was 250.84 mg of active ingredient per kilogram of the final flock weight. This consumption intensity exceeds the amount of antimicrob...

This study used new genetic and molecular tools to inhibit pathogenicity and infection by E. faecalis. In this study, we suggested that efaA gene plays a critical role in the biofilm formation and anti-efaA PNAs could decrease the formation of biofilm, as well as, anti-ftsZ PNAs could eliminate bacterial growth.

DiscussionAntibiotic resistance in environmental samples around wastewater treatment plants may pose a risk of exposure to workers and nearby residents. Results from the systematic review outlined in this protocol will allow to estimate the extend of exposure, to inform policy making and help to design future studies.

AbstractThe initial clinical status after subarachnoid hemorrhage (SAH) is an important outcome predictor, but the mechanisms behind the early brain injury (EBI) remains incompletely understood. Elevated neurofilament levels in the cerebrospinal fluid at protracted stages after SAH are associated with poor outcome, but the potential association between plasma neurofilament (pNfL) levels during EBI, disease severity on admission, and poor outcome remains unaddressed. Plasma NfL (pNfL) was measured by single molecule array in 44 SAH patients on admission and 24  h after ictus, as well as in 44 controls. Disease severity...

Staphylococcus aureus is one of the major causes of nosocomial infections. This organism produces powerful toxins and cause superficial lesions, systemic infections, and several toxemic syndromes. A total of 109 S. aureus strains isolated from a variety of infections like ocular diseases, wound infection, and sputum were included in the study. Minimum inhibitory concentration (MIC) was determined against 8 antimicrobials. PCR determined the presence of 16S rRNA, nuc, mecA, czrC, qacA/B, pvl, and toxin genes in S. aureus isolates. Pulse-field gel electrophoresis (PFGE), multi-locus sequence typing (MLST), SCCmec, spa-, and ...
