Evaluation of a selective chromogenic medium for detecting vancomycin-resistant...
Soares,Renata Oliveira; Rossato,Adriana Medianeira; Sambrano,Gustavo Enck; Tolfo,Neidimar Cezar Corrêa; Caierão,Juliana; Paim,Thiago Galvão da SilvaABSTRACT Rapid identification of vancomycin-resistant enterococci (VRE) can assist in choosing the appropriate treatment and preventing VRE spread. The performance of chromIDTM VRE agar was evaluated using 184 clinical isolates of Enterococcus spp. and reference strains. The test had a sensitivity of 95.52% but a low specificity of 30%.
MRSA from Santa Catarina State, Southern Brazil: intriguing epidemiological dif...
Silveira,Alessandro C.O.; Cunha,Gabriela R.; Caierão,Juliana; Cordova,Caio M. de; d'Azevedo,Pedro A.Methicillin-resistant Staphylococcus aureus(MRSA) is one of the most frequently isolated agents in both nosocomial and community settings. It is a constant challenge for antibacterial therapy. Therefore, it becomes essential to understand the epidemiology of MRSA isolates in the institution and/or region to guide empirical therapy. The objective of this study was to evaluate the epidemiological characteristics ...
Molecular epidemiology of heteroresistant vancomycin-intermediate Staphylococcu...
Silveira,Alessandro Conrado de Oliveira; Cunha,Gabriela Rosa da; Caierão,Juliana; Cordova,Caio Mauricio Mendes de; d'Azevedo,Pedro AlvesABSTRACTTo determine the epidemiological and molecular characteristics of 12 Staphylococcus aureus isolates presenting heteroresistance to vancomycin in laboratories of two cities in Santa Catarina, southern Brazil. Epidemiological data, including the city of isolation, health institution, and date of isolation were considered, as well as the associated clinical specimen. For molecular characterization, we anal...
Use of the D test method to detect inducible clindamycin resistance in coagulas...
Perez,Leandro Reus Rodrigues; Caierão,Juliana; Antunes,Ana Lúcia Souza; d'Azevedo,Pedro AlvesAccording to the National Committee for Clinical Laboratory Standards (NCCLS, 2004), a method to evaluate the inducible clindamycin resistance in accordance with an approach of the disks of erythromycin and clindamycin - the D test - has been reported. We analyzed the performance of this method in 200 coagulase negative staphylococci (CoNS) strains obtained from blood cultures of hospitalized patients at a gene...
