[Further research on the use of media with Na-RNA for isolating Shigella].

: The isolation of shigellae from the feces of patients with the use of Ploskirev's bactoagar with Na-RNA added at a concentration of 4 mg/ml has facilitated the laboratory diagnosis of dysentery due to the increased resolution of the medium. The isolation of shigellae on the medium with the stimulating agent added occurs 9% more frequently than on the control medium.
