37. Evolução de 9.416 bactérias Gram-negativas multirresistentes.
Resumo Objetivo: a resistência bacteriana hospitalar a múltiplos antibióticos é uma grande preocupação mundial. O objetivo deste estudo foi conhecer os agentes multidroga-resistentes (MDR), materiais clínicos, origem e evolução, e correlaciona-los à sensibilidade bacteriana e ao consumo de antimicrobianos. Métodos: foram avaliadas 9.416 bactérias

38. Early dissemination of OXA-72-producing Acinetobacter baumannii strain in Colombia: a case report
Nosocomial infections caused by carbapenem-resistant Acinetobacter baumannii isolates have reached epidemic levels in past decades. Currently this microorganism is responsible for outbreaks of difficult eradication and with high mortality rates worldwide. We herein report a rare case of an OXA-72-producing A. baumannii isolate colonizing a 47-year-old male p

39. Ecological competition and the incidence of Acinetobacter baumannii bloodstream infections in a teaching hospital in Southeastern Brazil
IntroductionRecently, pathogen ecology has been recognized as an important epidemiological determinant of healthcare-associated infections (HAIs). Acinetobacter baumannii is one of the most important agents known to cause HAIs. It is widespread in healthcare settings and exhibits seasonal variations in incidence. Little is known about the impact of competiti

40. Synergistic interactions in mixed-species biofilms of pathogenic bacteria from the respiratory tract
IntroductionMixed-species biofilms are involved in a wide variety of infections. We studied the synergistic interactions during dual-species biofilm formation among isolates of Pseudomonas aeruginosa, Acinetobacter baumannii, and Stenotrophomonas maltophilia.MethodsIsolates were cultured as single-species and all possible combinations of dual-species biofilm

41. Colistin and anti-Gram-positive bacterial agents against Acinetobacter baumannii
Introduction Acinetobacter baumannii has attained an alarming level of resistance to antibacterial drugs. Clinicians are now considering the use of older agents or unorthodox combinations of licensed drugs against multidrug-resistant strains to bridge the current treatment gap. We investigated the in vitro activities of combination treatments that included

42. The mazEF toxin-antitoxin system as a novel antibacterial target in Acinetobacter baumannii
Although analysis of toxin-antitoxin (TA) systems can be instructive, to date, there is no information on the prevalence and identity of TA systems based on a large panel of Acinetobacter baumannii clinical isolates. The aim of the current study was to screen for functional TA systems among clinical isolates of A. baumannii and to identify the systems’ loc

43. Synthesis of new 3-(2-chloroquinolin-3-yl)-5-phenylisoxazole derivatives via click-chemistry approach
Aqui relatamos a síntese de novos 3-(2-cloroquinolin-3-il)-5-fenilisoxazóis (3a-j) substituídos por click chemistry com rendimentos bons a moderados. Esta abordagem baseia-se na cicloadição regiosseletiva catalisada por cobre(I) entre diferentes óxidos de nitrila derivados de 2-cloroquinolina-3-carbaldeídos (2a-j) e fenilacetileno. Finalmente, estes d

44. Acinetobacter baumannii produtor de oxacilinases (OXA) no Brasil: impacto clínico, epidemiológico e opções terapêuticas
Seguindo uma tendência mundial, no Brasil, infecções por cepas de Acinetobacter baumannii multirresistentes (MRs) produtoras de carbapenemases do tipo oxacilinases (OXA) classe D de Ambler são atualmente consideradas uma emergência clínica e epidemiológica. Cepas de A. baumannii produtoras de OXA têm sido reportadas nos estados de Alagoas, Amazonas,

46. Bloodstream infection in patients with end-stage renal disease in a teaching hospital in central-western Brazil
Introduction Vascular access in patients undergoing hemodialysis is considered a critical determinant of bloodstream infection (BSI) and is associated with high morbidity and mortality. The purpose of this study was to investigate the occurrence of BSI in patients with end-stage renal disease using central venous catheters for hemodialysis. Methods A coho

47. Sulbactam-based therapy for Acinetobacter baumannii infection: a systematic review and meta-analysis
BACKGROUND: A number of studies have reported on the effectiveness of sulbactam-based therapies for Acinetobacter baumannii infection; however, there is little evidence that sulbactam-based therapies are more or less effective than alternative therapies. Unfortunately, there is a distinct lack of high quality data (i.e., from randomized controlled trials) av
