Genomic DNA microarrays for Entamoeba histolytica: applications for use in expression profiling and strain genotyping.

The parasite Entamoeba histolytica is a causative agent of dysentery and liver abscesses. Found predominantly in developing countries, this parasitic infection is responsible for significant morbidity and mortality. We have developed a genomic DNA microarray for E. histolytica. The array composed of 11,328 clones contains >2000 unique genes and was utilized for expression profiling and comparative genomic hybridizations of Entamoeba strains. We present a synopsis of our results to date and potential future applications of microarray technology for the study of Entamoeba biology.
