2. Antimicrobial resistance, diarrheagenic and avian pathogenic virulence genes in Escherichia coli from poultry feed and the ingredients
RESUMO Escherichia coli diarreiogênicas (DEC) e patogênicas para aves (APEC) são associadas a infecções intestinais e extraintestinais (ExPEC), respectivamente. O objetivo do presente trabalho foi avaliar a sensibilidade antimicrobiana, a presença de genes que codificam os fatores de virulência relacionados à DEC e APEC, e a classificação filogené

3. Fusarium solani keratitis: role of antifungal susceptibility testing and identification to the species level for proper management
ABSTRACT We report a patient with fungal keratitis caused by a multiresistant Fusarium solani in a tertiary care hospital located in southern Brazil. A 55-year-old man with a history of ocular trauma presented with keratitis in left eye. The patient has a complicated clinical course and failed to respond to local and systemic antifungal treatment, and requir

4. Inactivation of MarR gene homologs increases susceptibility to antimicrobials in Bacteroides fragilis
ABSTRACT Bacteroides fragilis is the strict anaerobic bacteria most commonly found in human infections, and has a high mortality rate. Among other virulence factors, the remarkable ability to acquire resistance to a variety of antimicrobial agents and to tolerate nanomolar concentrations of oxygen explains in part their success in causing infection and colon

5. An evaluation of false-positive rifampicin resistance on the Xpert MTB/RIF
BACKGROUND Mycobacterium tuberculosis (MTB) is one of the most significant causes of mortality and morbidity. Early diagnose is important especially in multiple drug resistant tuberculosis to avoid transmission. Traditional techniques requires at least one to three weeks for diagnosis of tuberculosis. Diagnostic delays with multiple drug resistant tuberculo

6. CTX-M extended-spectrum β-lactamase-producing Klebsiella spp, Salmonella spp, Shigella spp and Escherichia coli isolates in Iranian hospitals
Abstract This study was conducted in Iran in order to assess the distribution of CTX-M type ESBLs producing Enterobacteriaceae. From January 2012 to December 2013, totally 198 E. coli, 139 Klebsiella spp, 54 Salmonella spp and 52 Shigella spp from seven hospitals of six provinces in Iran were screened for resistance to extended-spectrum cephalosporins. After

7. Antimicrobial resistance and genetic diversity of Escherichia coli isolated from humans and foods
Antibiotic resistance has increased in recent years, raising the concern of public health authorities. We conducted a study of Escherichia coli isolates obtained from human and food samples to assess the prevalence of antimicrobial resistance and to determine the genotype and clonal relationship of 84 E. coli isolates (48 from humans and 36 from foods). An a

8. Draft genome sequence of blaVeb-1, blaoxa-10producing multi-drug resistant (MDR)
Pseudomonas aeruginosa strain VRFPA09 recovered from bloodstream infectionPseudomonas aeruginosa (P. aeruginosa ) bacteremia causes significant mortality rate due to emergence of multidrug resistant (MDR) nosocomial infections. We report the draft genome sequence ofP. aeruginosa strain VRFPA09, a human bloodstream isolate, phenotypically proven as MDR strain. Whole genome sequeBraz. J. Microbiol.. Publicado em: 2015-09

9. Nanoparticle-based drug delivery systems: promising approaches against infections
Despite the fact that many new drugs and technologies have been developed to combat the infectious diseases, these have continued to be global health challenges. The use of conventional antimicrobial agents against these infections is always associated with problems such as the development of multiple drug resistance and adverse side effects. In addition, th

10. Chloroquine sensitizes biofilms of Candida albicans to antifungal azoles
Biofilms formed by Candida albicans, a human pathogen, are known to be resistant to different antifungal agents. Novel strategies to combat the biofilm associated Candida infections like multiple drug therapy are being explored. In this study, potential of chloroquine to be a partner drug in combination with four antifungal agents, namely fluconazole, vorico

11. Ação do inibidor da enzima dipeptidil peptidase 4 sobre o pré-condicionamento isquêmico em pacientes portadores de diabetes mellitus tipo 2 e doença arterial coronariana estável / Effect of dipeptidyl peptidase-4 enzyme inhibitor on ischemic preconditioning in patients with type 2 diabetes and symptomatic coronary artery disease
Ischemic preconditioning (IPC) refers to the phenomenon in which short periods of myocardial ischemia and reperfusion promote resistance to a subsequent prolonged ischemic insult. Some hypoglycemic drugs, such as glibenclamide and repaglinide, are able to inhibit this protective phenomenon probably by its effects as blockers of adenosine triphosphate-depende

12. Heavy metal tolerance (Cr, Ag and Hg) in bacteria isolated from sewage
Samples of sewage from a university hospital and a chemistry technical school were analysed for the percentage of bacterial tolerance to chromium (Cr), silver (Ag) and mercury (Hg). Additionally, we investigated the effect of these metals on pigmentation and on some enzymatic activities of the metal tolerant strains isolated, as well as antimicrobial resista
