Abstract
<i>Acanthamoeba</i>spp. in Urine of Critically Ill Patients
Highlights
To the Editor: Free-living amebae are ubiquitous protists able to endure extreme temperature and pH in diverse environments (1)
Medical records were evaluated for patient age, sex, underlying diseases, length of hospital stay, use of central venous catheter, mechanical ventilation, antimicrobial drug use, and duration of urinary catheterization
Chemical urinalysis was performed by using a urine dipstick (Uriquest; Labtest Diagnostica, Lagoa Santa, Minas Gerais, Brazil), and urine leukocyte and erythrocyte counts were performed
Summary
To the Editor: Free-living amebae are ubiquitous protists able to endure extreme temperature and pH in diverse environments (1). To estimate the prevalence of Acanthamoeba spp. in urine, on March 3 and 4, 2008, we collected urine samples from indwelling urinary catheters of all critically ill patients in the intensive care units of a tertiary care 2,000-bed university hospital (Hospital das Clínicas, University of São Paulo). Medical records were evaluated for patient age, sex, underlying diseases, length of hospital stay, use of central venous catheter, mechanical ventilation, antimicrobial drug use, and duration of urinary catheterization. Samples were examined microscopically and cultured for amebae.
