Mechanisms of Resistance in Multiple-Antibiotic-Resistant Escherichia coli Strains of Human, Animal, and Food Origins
Yolanda Sáenz,Laura Briñas,Elena Domínguez,Joaquim Ruiz,Myriam Zarazaga,Jordi Vila,Carmen Torres +6 more
TL;DR: Seventeen multiple-antibiotic-resistant nonpathogenic Escherichia coli strains of human, animal, and food origins showed a wide variety of antibiotic resistance genes, many of them carried by class 1 and class 2 integrons.
Journal ArticleDOI
Antibiotic resistance in Campylobacter strains isolated from animals, foods, and humans in Spain in 1997-1998.
TL;DR: The increasing rates of Campylobacter resistance make advisable a more conservative policy for the use of antibiotics in farm animals.
Journal ArticleDOI
β-Lactamases in Ampicillin-Resistant Escherichia coli Isolates from Foods, Humans, and Healthy Animals
TL;DR: TEM, SHV-, and OXA-type beta-lactamases were studied by PCR with 124 ampicillin-resistant (AMP(r)) Escherichia coli isolates recovered from foods of animal origin and feces of humans and healthy animals as mentioned in this paper.
Journal ArticleDOI
Macrolide resistance genes in Enterococcus spp.
Aránzazu Portillo,Fernanda Ruiz-Larrea,Myriam Zarazaga,Ana Alonso,José L. Martínez,Carmen Torres +5 more
TL;DR: Sequencing of the MSrAPCR products from either erythromycin-susceptible, low-level-resistant, or highly resistant E. faecium strains showed that the amplicons did not correspond to the msrA gene described for Staphylococcus epidermidis but corresponded to a new putative efflux determinant, which showed 62% identity with themsrA gene at the DNA level and 72% similarity at the amino acid level.
Journal ArticleDOI
Detection of Escherichia coli harbouring extended-spectrum β-lactamases of the CTX-M, TEM and SHV classes in faecal samples of wild animals in Portugal
Daniela Costa,Daniela Costa,Patrícia Poeta,Yolanda Sáenz,Laura Vinué,Beatriz Rojo-Bezares,Ahlem Jouini,Myriam Zarazaga,Jorge Rodrigues,Carmen Torres +9 more
