Abstract INTRODUCTION: We aimed to evaluate the effectiveness of a symbiotic product to decolonize the intestinal tract of patients harboring multidrug-resistant (MDR) Gram-negative bacilli and to prevent nosocomial infections. METHODS: This was a randomized, double blind, placebo-controlled clinical t...
Abstract Pan-drug resistant Gram-negative bacteria, being resistant to most available antibiotics, represent a huge threat to the medical community. Colistin is considered the last therapeutic option for patients in hospital settings. Thus, we were concerned in this study to demonstrate the membrane perm...

One of the most important features of the post-antibiotic era in the late 20th century is the resurgence of colistin for the treatment of extensively drug resistant gram-negative bacteria (XDR). Colistin is a narrow spectrum anti-biotic, active against microorganisms with clinical significance such as Ac...
The microbiota associated with failed implants includes Pseudomonas and Gram-negative enteric rods. The present study reports a case of Escherichia coli associated to early implant failed that was resistant in vitro to doxycycline, amoxicillin, metronidazole, and clindamycin, but was susceptible in vitro...
Background The increment of resistant strains to commonly used antibiotics in clinical practices places in evidence the urgent need to search for new compounds with antibacterial activity. The adaptations that Antarctic microorganisms have developed, due to the extreme environment that they inhabit, prom...

Due to the great variability in antimicrobial resistance patterns, local reports of cumulative antimicrobial susceptibility data are necessary in every health center. The purpose is to guide clinical decisions and the early detection of patterns that allow preventive measures to avoid dissemination of re...
El problema de la resistencia bacteriana a antimicrobianos presenta una elevada prevalencia, con serias implicancias desde el nivel de salud pública hasta los resultados de la terapia individual. Los objetivos del trabajo fueron estudiar niveles de resistencia y su relación con el consumo de antimicrob...

Meropenem es un compuesto del grupo carbapenem, con un amplio espectro antibacteriano y rápida actividad bactericida. Esta actividad es superior sobre bacilos gram negativos fermentadores como klebsiella sp y E. coli, e inferior sobre pseudomonas sp. Y A. baumannii. En cuanto a estas dos últimas bacter...
Meropenem is more stable than imipenem to renal dehydropeptidase I and can be used as a monodrug. It is bactericidal against most grampositive and gramnegative, aerobic and anaerobic species. Compared to imipenem, meropenem is more active against pseudomonas aeuginosa, burkholderia cepacia and some multi...
