Austrailian study reports Blastocystis infection more common in certain urban areas

Researchers used fecal samples and post code information from patients at four public hospitals in Sydney to determine that Blastocystis infection is more likely to occur in certain geographic regions.  A total of 910 records were examined for patients seen from 2007-2010, and 580 cases with post code data were examined.  Blastocystis was found in 57% of the samples, Giardia in 27%, and D. fragailis in 12%.  Age prevalnece decreased up to age 24, but increased from age 25 onward.  The full text text of the paper is available in the Journal of Public Health Research.
