Emerging mupirocin resistance in methiciüin-resistant Staphylococcus aureus isolates at a tertiary care children's hospital in Argentina.

In Latin America, few studies have been done in mupirocin resistance and biofilm formation in methicillin-resistant Staphylococcus aureus (MRSA). This study investigated mupirocin-resistance in MRSA isolates from pediatric patients with bacteremia and their ability to form biofilm. Antibiotic resistance was analyzed with the Kirby-Bauer test and the broth microdilution method.

Carnosic acid acts synergistically with gentamicin in killing methicillin-resistant Staphylococcus aureus clinical isolates.

Background: Methicillin-resistant Staphylococcus aureus (MRSA) is resistant to different commonly used antibiotics, stressing the need for further strategies to treat this human pathogen with worldwide prevalence. The use of phytochemicals within the current pharmacology is a promising approach to enhance the antimicrobial activity of common antibiotics in the battle against these bacteria.

Purpose: The purpose of this study was to determine the antimicrobial effectiveness of carnosic acid, the major constituent of Rosmarinus officinalis L.

[Microbiological features and risk factors for acquiring multidrug-resistant Acinetobacter baumannii bacteremia in pediatric patients. Case-control study].

Background: Multidrug-resistant Acinetobacter baumannii (MAB) is an important nosocomial pathogen.

Objectives: To analyze the risk factors for acquiring MAB, and the clinical and microbiological characteristics of MAB bacteremia (MABB) in children.

Materials And Methods: Control-case study 2005-2008.

Trends in the resistance profiles of Acinetobacter baumannii endemic clones in a university hospital of Argentina.

A total of 925 Acinetobacter spp. isolates were collected from routine clinical samples of patients admitted to the university hospital of Buenos Aires city during the period 2004-2012. From this collection, 129 isolates identified as Acinetobacter baumannii were selected for molecular studies.
