| Vários trabalhos vêm demonstrando a importância do estudo de produtos naturais como fonte alternativa para novos antimicrobianos ou que venham potencializar os já existentes. Neste contexto este trabalho teve como objetivo investigar a atividade antibacteriana e as possíveis interações entre o óleo essencial de Cymbopogon citratus combinados a aminoglicosídeos frente a linhagens padrões e multirresistentes de S. aureus, E. coli e de P. aeruginosa provenientes de isolados clínicos. Um ensaio de microdiluição foi realizado para verificar a atividade antibacteriana e as possíveis interacções entre o produto natural e os antibióticos, utilizando uma concentração sub-inibitória. Através dos resultados foi constatado a interferência sinérgica dos... |

| Los pacientes portadores de enfermedad fibroquística presentan manifestaciones respiratorias a repetición o crónicas, las cuales se acompañan de infecciones bacterianas. Pseudomonas aeruginosa es la especie bacteriana que se aísla con mayor frecuencia en estos pacientes a partir de muestras de origen respiratorio. Teniendo en cuenta que las infecciones por esta bacteria son difíciles de tratar y que la terapia usualmente empleada es la combinación de un aminoglucósido con un antibiótico beta-lactámico, se analizó el comportamiento por el método de microdilución en caldo de 54 cepas aisladas de pacientes con fibrosis quística frente a cuatro beta-lactámicos (carbenicilina, azlocilina, cefotaxima, ceftazidima), y se observó que el 85% de las cepas fueron... |

| In vitro antimicrobial susceptibility of strains of Pseudomonas aeruginosa by standard diffusion disk test and a modified method, by the addition Tris-EDTA, was evaluated. Increase in sensitivity of agent using modified method was observed mainly in aminoglycosides (amikacin, gentamicin, tobramycin), quinolones (ofloxacin and norfloxacin) and cephalosporins (cefoperazone and ceftazidime) groups. by standard diffusion disk test and a modified method, by the addition Tris-EDTA, was evaluated.

| The heteroantagonism between Enterobacter agglomerans, isolated from the gastrointestinal tract of American vulture Coragyps atratus, and Pseudomonas aeruginosa isolated from a hospital environment was evaluated. The slow (layer) and the wells (direct) techniques were tested, using agar and soy tryptone broth pH 7.3 at 37ºC. Through the slow method from 196 tests, inhibition growth halos, related heteroantagonism phenomenon observed in 118, corresponding to 60.2% positive results. Equivalent positive results were detected using wells (direct) methodology. The seven samples of E. agglomerans tested were capable of revealing heteroantagonism in the experimental conditions; antagonism reveled by the presence of a clear growth inhibition halo. The added 1%... |

| Abstract In this review, we explore some aspects of Pseudomonas aeruginosa virulence factors that are related to disease development in healthy organisms and resistance to antibiotics. This pathogen is one of the most clinically and epidemiologically important bacteria in Brazil, being the major cause of opportunistic infections. Among the virulence factors, biofilm formation acting of manner different in the organism. Furthermore, we review several P. aeruginosa genes that act in antimicrobial resistance, such as β-lactamases against β-lactamers. The resistance to pied-lactamases in P. aeruginosa is associated to resistance to the broad-spectrum cephalosporin. On the other hand, there is a group of synthetic broad-spectrum antibiotics acting on DNA... |

| This study evaluated, in vitro, the antimicrobial activity and the anti-adherent property of xylitol (0.5, 2.5 and 5.0%, w/v) on two Pseudomonas aeruginosa strains (ATCC 9027 and clinical). The assay of antimicrobial activity was performed to determine a minimum inhibitory concentration (MIC) and the adhesion test was performed, by which the parameters regarding, growth in the culture medium, number of colony forming units (CFUs) released and slide evaluation by scanning electron microscopy (SEM) were analyzed. The Statistical Package for the Social Sciences (SPSS) was employed for statistical analysis. Results showed that xylitol had no antimicrobial activity on these strains; however, the inhibition of bacterial adherence was observed in microphotographs... |

| ABSTRACT Introduction: Biofilm production is an important mechanism for the survival of Pseudomonas aeruginosa and its relationship with antimicrobial resistance represents a challenge for patient therapeutics. P. aeruginosa is an opportunistic pathogen frequently associated to nosocomial infections, especially in imunocompromised hosts. Objectives: Analyze the phenotypic biofilm production in P. aeruginosa isolates, describe clonal profiles, and analyze quorum sensing (QS) genes and the occurrence of mutations in the LasR protein of non-biofilm producing isolates. Methods: Isolates were tested for biofilm production by measuring cells adherence to the microtiter plates. Clonal profile analysis was carried out through ERIC-PCR, QS genes were by specific... |

| Pseudomonas aeruginosa is an important and frightening microorganism for patients suffering from cancer. Multiresistant P. aeruginosa (MRPA) may appear as a consequence of exposure to multiple antibiotics or from a breakdown in infection control practices. This article reports an MRPA outbreak in a cancer treatment centre and the consequent case control study. Mechanical ventilation was identified as being the main risk factor for developing MRPA colonisation or infection; molecular analysis confirmed the outbreak. A multifaceted strategy was adopted, involving reinforcing hand-washing practices, contact isolation, antibiotic restriction and suction devices for mechanically-ventilated patients. MRPA was controlled and the outbreak ended. Such strategy may... |

| ABSTRACT Purposes: Shoulder arthroplasty (SA) has been performed by many years for the treatment of several conditions, including osteoarthritis and proximal humeral fractures following trauma. Surgical site infection (SSI) following Shoulder arthroplasty remains a challenge, contributing to increased morbidity and costs. Identification of risk factors may help implementing adequate strategies to prevent infection. We aimed to identify pre- and intra-operative risk factors associated with deep infections after Shoulder arthroplasty. Methods: An unmatched case-control study was conducted to describe the prevalence, clinical and microbiological findings, and to evaluate patient and surgical risk factors for prosthetic shoulder infection (PSI), among 158... |
