[The excretion of Shigella antigens in persons recovering from dysentery].

Shigella antigens can be detected in the excreta of convalescents after dysentery for a long time. Most frequently these antigens occur in feces, less frequently in urine and rarely in saliva. According to indirect data, S. flexneri 1-6 antigens can be detected in excreta for a longer period after convalescence than S. sonnei antigens. When antigen indication is used for the diagnosis of dysentery and epidemiological analysis is carried out, one should bear in mind the length of the agent persistence in the body, related to Shigella type.
