摘要：
Species of Acanthamoeba, known to cause keratitis (AK) and granulomatous encephalitis in humans are frequently isolated from a variety of water sources. In this study, 13 Acanthamoeba isolates from swimming pools were classified at the genotype level based on the sequence analysis of the Acanthamoeba small-subunit rRNA gene. Nine of the 13 isolates were genotype T5, three were genotype T4, and one was T3. Several genotypes have been reported worldwide as causative agents of AK, including genotypes 13, T4, and T5. The present study indicates that genotype T5 is a common contaminant in swimming-pool water. (C) 2010 Elsevier B.V. All rights reserved.
