[The level of enterobiasis infectivity in children in relation to the sanitary status of preschool institutions].

Nursery schools and kindergartens have been examined in Rostov-on-Don. Five most essential factors based on the determination of signs informativeness and prognostic coefficients and responsible for possible enterobiasis determination have been identified: the state of water supply, staffing with personnel, presence (absence) of the round-the-clock groups, overcrowded groups, location of bedrooms. An attempt is made to classify kindergartens according to these indexes.
