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 farms and the results suggest that the increasing prevalence of antibiotic resistant bacteria in Chilean salmon farming resistance is partly attributable to the acquisition, dissemination and stable maintenance of a class 1 integron. Thus, a continuous surveillance of these resistance elements even in absence of antibacterial therapy is urgently required to evaluate the potential role of fish farming environments as reservoirs and source of elements composing the mobilome, such as conjugative plasmids and integrons, increasing the risk of their dissemination to human pathogens through horizontal transfer. Author Contributions MD planned the experiments, analyzed the data, and participated in manuscript drafting. CM isolated and provided the studied strains, studied antimicrobial susceptibility patterns of resistant bacteria, analyzed the data, wrote the m...

We describe the clinical outcomes of adults who received ECMO in septic shock.MethodsWe retrospectively studied adults supported on veno-arterial or veno-venous modes of ECMO with septic shock at the time of cannulation from 1/1/2009-12/31/2016 at a quaternary medical center in the United States. The primary outcome was rate of survival to hospital discharge and time to survival using Kaplan-Meier survival estimates. We analyzed survival by mode, previous cardiac arrest and timing of cannulation (

The levels of HMF and F in Chinese vinegars from different regions were analyzed and discussed. F ranged from 4.35 to 313.95 mg/L, with an average value of 136.71 mg/L, while the mean level of HMF was 103.69 mg/L (26.83–455.13 mg/L). A significant positive corr...

This exploratory study aims at building an inventory of consumer beliefs about organic food. To reach this objective, we conducted a content analysis of online comments about organic food posted on news websites and forums in German-speaking countries (n=1,094) and the United States (n=1,069). Such user-generated content has emerged as an abundant source of insight for consumer research, although very little has been ex...

At the initial stage of the brown-rot decay, penetrating hyphae of the fungi are observed in ray parenchyma. Since starch grains are known to be present in the ray parenchyma of sapwood, investigation of the functions and roles of the starch-degrading enzymes is important to understand the initial stage of brown-rot decay. We purified and characterized two starch...

The objectives of this study were to examine relative transcripts linked to egg and embryo quality and determine expression between low-hatch and high-hatch egg batches through early development (0, 24, 48, and 96 h post-fertilization; HPF). RNA was extracted from eggs/embryos of nine females (n = 4 high-quality, n = 5 low-quality) and Real-Time PCR was used to quantify relative gene expression. The transcripts assessed in this study perform critical cellular functions, including tubulin β (tubb), cathepsin D (ctsd), cathepsin Z (ctsz), cathepsin B (ctsb), cyclin B (ccnb1), exportin-1 (xpo1), ring finger pro...
