Journal ArticleDOI
High Prevalence of Multidrug-Resistant Klebsiella pneumoniae Harboring Several Virulence and β-Lactamase Encoding Genes in a Brazilian Intensive Care Unit.
R. Ferreira,Brenda C M da Silva,Graziela S. Rezende,Rafael Nakamura-Silva,André Pitondo-Silva,Emeline Boni Campanini,Márcia C. A. Brito,Eulália M. L. da Silva,Caio César de Melo Freire,Anderson F. Cunha,Maria Cristina da Silva Pranchevicius +10 more
TL;DR: The wide variety of MDR K. pneumoniae harboring β-lactams and virulence genes strongly suggest a necessity for the implementation of effective strategies to prevent and control the spread of antibiotic resistant infections.
Journal ArticleDOI
Molecular typing and virulence markers of Yersinia enterocolitica strains from human, animal and food origins isolated between 1968 and 2000 in Brazil.
Juliana Pfrimer Falcão,Deise Pasetto Falcão,André Pitondo-Silva,Ana Carolina Malaspina,Marcelo Brocchi +4 more
TL;DR: The results revealed the virulence potential of a bio-serotype 1A/O : 10 strain, suggesting that food contaminated with Y. enterocolitica biotypes 1A and 1A may cause infection, and suggests that ERIC-PCR may be used as a tool to reveal clues about the virulent potential of Y. entersocolitICA strains.
Journal ArticleDOI
Aquatic environments polluted with antibiotics and heavy metals: a human health hazard
Vinicius Vicente Martins,Maria Olívia Barboza Zanetti,André Pitondo-Silva,Eliana Guedes Stehling +3 more
TL;DR: The isolate EW32 presented a conjugative plasmid with coresistance to tetracycline and copper, reinforcing the concern that antibiotic resistance by acquisition of plasmids can be induced by the selective pressure of heavy metals in the environment.
Journal ArticleDOI
Molecular epidemiology of extended-spectrum-β-lactamase-producing Klebsiella pneumoniae over a 10 year period in Calgary, Canada
Gisele Peirano,Jessica Hung King Sang,André Pitondo-Silva,Kevin B. Laupland,Johann D. D. Pitout +4 more
TL;DR: The study highlights the importance of molecular epidemiology in providing insight into the emergence, characteristics and distribution of STs among ESBL-producing K. pneumoniae.
Journal ArticleDOI
Molecular characteristics of extended-spectrum β-lactamase-producing Escherichia coli from Rio de Janeiro, Brazil.
TL;DR: The authors' results illustrate the predominance of phylogroup A (52%), ST410 (CC 23) and CTX-M-15 among ESBL-producing E. coli isolates from hospitals in Rio de Janeiro.
