Improved detection of Shigella using Escherichia coli medium enrichment: Polymerase chain reaction from stool samples.

Laboratory diagnosis of shigellosis using conventional culture technique is limited by lower sensitivity and higher turnaround time. Here, we have evaluated the role of polymerase chain reaction from stool samples after enrichment in Escherichia coli medium for detection of Shigellae. The technique not only increased the sensitivity but also decreased the turnaround time.
