title: Attempted mathematical models of seasonal dynamics of cestode infections in intermediate and final hosts.
abstract: The possibility of describing cestode infection dynamics in various host groups (e.g in birds, fishes and copepods) by trigonometric and parabolic polynomials is examined. The necessity of observing certain requirements during data collection for the correct application of the examined models is shown; the possibility of applying a parabolic polynomial in case of non-observing of some of these requirements has been found. The mathematical models obtained are of prognostic value and may serve as a measure of the uniformity and validity of the empirical data.
