The sensitivity and specificity of bloody diarrhea in the diagnosis of shigella gastroenteritis in a Shigella sonnei prevalent center was investigated.

The shigella-proven gastroenteritis cases who were admitted to Hacettepe University İhsan Doğramacı Children's Hospital Diarrheal Diseases Unit (Jan 2003 - Oct 2006) constituted the study group (n=65). Age- and sex-matched children admitting to the same center with non-shigella diarrhea constituted the control group (n=65).

The sensitivity, specificity, and positive and negative predictive values of bloody diarrhea were found to be 30%, 100%, 100% and 58%, respectively. Sensitivity of bloody diarrhea in the diagnosis of shigella gastroenteritis was low in this center. New strategies and recommendations in the management of mild nonbloody cases are needed.
