The rectal swab and the stool culture were compared in order to verify their relative efficacies in the isolation of Shigella. A total of 320 cases were included in this study. Triplicate examinations by swab and stool were attempted in each case but this was not always possible. There was a total of 652 examinations either by swab or stool. Of these 35.4% were positive by swab which only 19% were positive by stool. When divided into symptomatic groups according to those with blood in the stool and those without, there is a closer relationship and most especially when more then one examination is used. In cases with fever and blood and with three successive examinations by stool and swab 68% were positive by swab and 71% positive by stool culture. In cases with blood without fever, 64.5% were positive by swab and 58% by stool. In cases with fever only there were 23.6% positive by swab and 22.4% positive by stool. In milder cases, without either of these symptoms the swab gave 25.5% positive while the stool gave only 11.6%. Therefore it may be seen that except in milder cases the three successive stool culture closely approximates the swab and may be used as a satisfactory substitutes when for various reasons the swab cannot be used.
