[Epidemiologic aspects of using the dysenterin skin test in institutions for pre-school children for the purpose of detecting potential sources of infection].

A possibility of considerable reduction of dysentery morbidity in creches and kindergartens by isolation of portential sources of infection among the personnel and children revealed as a result of repeated bacteriological examination, positively reacting to dysenterin was demonstrated in two controlled epidemiological trials. The efficacy of this measure became much less when the test and the corresponding bacteriological examination were performed in the personnel alone. As a whole, the high incidence of positive results of the skin-allergic test in practically healthy children and adults, with an extremely rare isolation of shigellae in persons positively reacting to dysenterin, even in their repeated bacteriological examination, pointed to rather limited possibilities of an effective use of this test in antiepidemic practice for detection of potential sources of infection.
