Increased recovery of enteric pathogens by use of both stool and rectal swab specimens.

During 1984, the recovery of enteric pathogens from patients with acute diarrhea was enhanced by the use of both rectal swab and stool specimens. With 513 patients for whom both methods were used, the overall recovery rate was increased a minimum of about 10%. Almost 50% of the organisms recovered were detected by only one method. For maximum recovery of diarrheal agents, the use of both methods is recommended when possible.
