Resistencia a antimicrobianos en diferentes biotipos de Acinetobacter baumannii aislados en el norte de Chile

Background: Acinetobacter baumannii nosocomial outbreaks are common and the microorganism is frequently resistant to multiple antimicrobials. There is little information about Acinetobacter baumannii antimicrobial susceptibility in the northern region of Chile. Aim: To identify different Acinetobact...

There is little information about Acinetobacter baumannii antimicrobial susceptibility in the northern region of Chile. Aim: To identify different Acinetobacter baumannii biotypes isolated from clinical samples and to determine their antimicrobial susceptibility. Material and methods: One hundred twenty three Acinetobacter baumannii isolates were studied. The identification and typing of Acinetobacter baumannii was based on phenotypic characteristics. Antimicrobial susceptibility was investigated using agar dilution techniques. Results: Most Acinetohacter baumannii strains were isolated from wounds, urinary and respiratory infections. Seven biotypes were isolated, being biotype 9 the most frequent. lmipenem was the antimicrobial with the higher activity against the microorganism. Amikacin, cefoperazonesulbactam, ampicillinsulbactam and ceftazidime had a moderate activity. There were high resistance levels to ampicillin and older cephalosporins. Conclusions: Acinetobacter baumannii is emerging as a significant nosocomial pathogen in Chile and shows high resistance rates to multiple antibiotics.info:eu-repo/semantics/openAccessSociedad Médica de SantiagoRevista médica de Chile v.127 n.8 19991999-08-01text/htmlhttp://www.scielo.cl/scielo.php?script=sci_arttext&pid=S0034-98871999000800006es10.4067/S0034-98871999000800006
