The epidemiological characteristics of 18 patients with acinetobacter bacte
remia were analyzed. Patients (mean age, 55.5 years) developed bacteremia a
fter an average of 14.1 days of hospitalization. Fifteen of 16 patients sur
vived bacteremia caused by Acinetobacter baumannii. Cultures of blood from
the remaining two patients yielded Acinetobacter lwoffii. Most patients (78
%) resided in the general ward, while four patients (22%) were under intens
ive care. Genotyping by arbitrarily primed polymerase chain reaction analys
is and the temporal sequence of isolation were more useful than phenotyping
by antimicrobial susceptibility in the determination of the source of bact
eremia, and the intravascular catheter was the leading infection source (39
% of cases). The possibility of an association of glucose with the pathogen
esis of acinetobacter infection was raised.
