New qnr gene cassettes associated with superintegron repeats in Vibrio cholerae O1.
TL;DR: A novel qnr determinant emerged in ciprofloxacin-resistant Vibrio cholerae O1 from the Amazon region of Brazil and showed 89% identity with V. parahaemolyticus superintegron repeats.
Journal ArticleDOI
Cholera outbreaks in Nigeria are associated with multidrug resistant atypical El Tor and non-O1/non-O139 Vibrio cholerae.

TL;DR: The recent Nigeria outbreaks have been determined by multidrug resistant atypical El Tor and non-O1/non-O139 V. cholerae strains, and it seems that the typical El Tor, from the beginning of seventh cholera pandemic, is no longer epidemic/endemic in this country.
Journal ArticleDOI
Carbapenem-resistant Acinetobacter baumannii from Brazil: role of carO alleles expression and blaOXA-23 gene.
Érica L. Fonseca,Erica Miranda Damásio Scheidegger,Fernanda S. Freitas,Rosângela Cipriano,Ana Carolina Paulo Vicente +4 more
TL;DR: The basis of carbapenem resistance in clinical A. baumannii isolates from different Brazilian regions was analyzed and it was possible to associate the carO alleles and their expression with imipenem Resistance, highlighting the possible influence of CarO type in this phenotype.
Journal ArticleDOI
Vibrio cholerae O1 lineages driving cholera outbreaks during seventh cholera pandemic in Ghana
Cristiane C. Thompson,Fernanda S. Freitas,Michel A. Marin,Érica L. Fonseca,Iruka N. Okeke,Ana Carolina Paulo Vicente +5 more
TL;DR: This study showed that distinct V. cholerae O1 were the determinants of cholera outbreaks in Ghana, and these strains were characterized by means of Multilocus Sequence Analysis (MLSA), genes from the virulence core genome (VCG), and genes related to the choleragenic phenotype.
Journal ArticleDOI
The colistin-only-sensitive Brazilian Pseudomonas aeruginosa clone SP (sequence type 277) is spread worldwide.
TL;DR: In this paper, the authors applied the multilocus sequence typing (MLST) scheme for determining the epidemiology of colistin-only-sensitive (COS) Brazilian P. aeruginosa clone SP.
