Vigilancia de resistencias a los antimicrobianos: estudio VIRA 2006
Enfermedades Infecciosas y Microbiología Clínica, 2006
INTRODUCTION. The objective of the study was to know the current situation of the antimicrobial sensitivity patterns of the main multi-resistant bacteria and to analyze any possible changes with respect to the VIRA study carried out in 2001. METHODS. The 40 participating hospitals sent a total of 1,425 microorganisms isolated in February 2004, distributed as follows: penicillin-resistant Streptococcus pneumoniae (139), methicillin-resistant Staphylococcus aureus (289), clinically significant coagulase-negative staphylococci (158), ampicillin-resistant Enterococcus faecium (89) and Enterococcus faecalis (2), ampicillin-resistant Haemophilus influenzae (85), ciprofloxacin-resistant Escherichia coli (346), Pseudomonas aeruginosa (187), and Acinetobacter baumannii (130). The hospitals provided epidemiological data on these microorganisms. Sensitivity was determined by the broth microdilution method.
Alarma por la resistencia a antimicrobianos

La creciente resistencia a los antimicrobianos (RAM) es un problema apremiante que de no combatirse a tiempo puede comprometer la salud de las generaciones futuras, con un retorno a la era preantibiotica. Frente a esa amenaza, los organismos sanitarios internacionales convocaron a todos los paises para coordinar renovadas estrategias de lucha contra la RAM, promoviendo el enfoque de “una salud” con la participacion de diferentes actores e instituciones. Este manuscrito proporciona informacion actualizada, explicando que la RAM no es mas un dilema medico sino un fenomeno complejo que ademas afecta la produccion agroveterinaria, el desarrollo y la economia de los paises. La exposicion a antibioticos contribuye a la seleccion de mutantes resistentes y favorece la transferencia horizontal de elementos geneticos moviles como plasmidos, integrones y tranposones que portan varios genes de resistencia contra distintas familias de antibioticos. Las antibioticoterapias, aun en situaciones jus...
Resistencia a antimicrobianos en cepas de Enterococcus sp aisladas en hospitales del norte de Chile
Revista chilena de infectología, 2006
Resistance to antimicrobial drugs in Enterococcus sp strains isolated in hospitals of Northern Chile The prevalence of different species of Enterococcus and the resistance to antimicrobial drugs was studied in strains isolated in 5 hospitals of Northern Chile. A total of 249 of Enterococcus spp strains were included in this study. Enterococci were mostly isolated from urine and wounds. Among five species identified, E. faecalis and E. faecium were most frequently isolated in the all hospitals. High susceptibility to beta-lactam antibiotics, moderate resistance to tetracycline, ciprofloxacin and eritromycin, and high resistance to chloramphenicol was observed. Vancomycin resistance was absent. Approximately 12% of Enterococcus spp strains presented high level of gentamicin resistance. Multiresistance to 3 o more antimicrobial agents was detected in 30% of total Enterococcus strains studied.

Introduction. Surveillance systems play a key role in the detection and control of bacterial resistance. It is necessary to constantly collect information from all institutions because the mechanisms of bacterial resistance can operate in different ways between countries, cities and even in hospitals in the same area. Therefore local information is important in order to learn about bacterial behaviour and design appropriate interventions for each institution. Between January 2003 and December 2004, the Centro Internacional de Entrenamiento e Investigaciones Médicas (CIDEIM) developed a surveillance project in 10 tertiary hospitals in 6 cities of Colombia. Objectives. Describe the trends of antibiotic resistance among the isolates of Escherichia coli, Klebsiella pneumoniae, Pseudomona aeruginosa, Acinetobacter baumannii and Enterobacter cloacae, five of the most prevalent nosocomial Gram negative pathogens. Materials and Methods: The susceptibility tests were performed by automated methods in 9 hospitals and by Kirby Bauer in 1 hospital. Antibiotics with known activity against Gram negatives, according to the Clinical Laboratory Standards Institute guidelines, were selected. The laboratories performed internal and external quality controls. During the study period, the information was downloaded monthly from the databases of each microbiology laboratory and sent to CIDEIM where it was centralized in a database using the system WHONET 5.3. Results. The high resistance rates reported especially for A. baumannii, evidenced the presence of multidrug resistant bacteria in both ICUs and wards at every studied institution. Conclusions. The creation of a national surveillance network to improve our capabilities to detect, follow up, and control the antibiotic resistance in Colombia is urgently needed.
