Phenotypic zinc resistance does not correlate with antimicrobial multi-resistance in fecal E. coli isolates of piglets
ConclusionOur findings argue against a co-selection mechanism of antimicrobial drug-resistance and zinc tolerance after dietary zinc supplementation in weaning piglets. An explanation for an increase in multi-drug resistant isolates from piglets with high zinc dietary feeding could be that resistant bacteria to antimicrobial agents are more persistent to stresses such as zinc or copper exposure.
CONCLUSIONSThefosA3 gene is the primary mechanism of fosfomycin resistance in CRKP and can be transmitted widely by plasmid in hospitals. Mutations in murA and glpT were found in fosfomycin-resistant fosA3-negative CRKP.
ConclusionsThe results highlight the importance of monitoring farm environments for Johne ’s disease. This disease is a growing concern for dairy and beef producers in Ireland, and sampling the farm environment may offer a useful means to rapidly screen for the presence of MAP. Non-pathogenic common enteric commensal and multiple-drug-resistantE. coli may contribute to AMR acting as a reservoir and transferring resistance to other species/pathogens in the environment.
ConclusionsIn ESBL-E. coli RUTI, most recurrences were caused by the initial infecting strain. The high frequency of the multidrug-resistant fimH30Rx subclone and its association with multiple recurrences warrants further attention and early detection of this subclone in patients at risk of developing RUTI with ESBL-producing E. coli.
ConclusionsOur study shows that fosfomycin-resistantE. coli strains are isolated in the majority of the cases in elderly people with complicated UTIs and belong the pandemic ST131 clone. To our knowledge, we describe, for the first time in Spain, the gene fosA3, which alerts for a future dissemination that should be monitored.
Publication date: Available online 12 February 2020Source: Food ControlAuthor(s): Kinga Wieczorek, Łukasz Bocian, Jacek OsekAbstractThe aim of the present study was to assess the prevalence of Campylobacter on chicken carcasses tested in Poland during 2014–2018 and to evaluate the antimicrobial susceptibility of the recovered isolates. The results were compared to the previous similar investigations performed in 2009–2013 [Wieczorek K. &Osek J. (2015). A five-year study on prevalence and antimicrobial resistance of Campylobacter from poultry carcasses in Poland. Food Microbiology, 49, 161–165]. A tot...
te; T Abstract Bacteria within biofilms are more resistant to antibiotics and chemical agents than planktonic bacteria in suspension. Treatment of biofilm-associated infections inevitably involves high dosages and prolonged courses of antimicrobial agents; therefore, there is a potential risk of the development of antimicrobial resistance (AMR). Due to the high prevalence of AMR and its association with biofilm formation, investigation of more effective anti-biofilm agents is required. From ancient times, herbs and spices have been used to preserve foods, and their antimicrobial, anti-biofilm and anti-quorum sensi...
ConclusionsThe findings indicate that dietary habit as well as past antimicrobial use and travel to high-risk country are associated with the risk of fecal carriage of drug-resistant commensalE. coli.
Antimicrobial resistance in N'Djamena (Chad): Four-year experience of the French Forward Medical and Surgical Team engaged in the "Barkhane Operation". Med Mal Infect. 2020 Feb 05;: Authors: Cardinale M, Bourbotte-Salmon F, Scheiwe C, Boulezaz S, Ridet M, Laitselart P Abstract OBJECTIVES: Knowledge of local antimicrobial resistance (AMR) patterns is required for effective empirical treatment of bacterial diseases. Very little is known about current resistance patterns of common pathogenic bacteria in the African region and particularly in the Sahel region. We aimed to describe the local bacte...
