title: [On the possibility of vertical transmission of Trichinella and the impact of its invasion].
abstract: Whether experimentally infected female rats can transmit Trichinella in utero and its invasion may affect the immunity of their offspring has been investigated. There is evidence that maternal antibodies have a significant impact on the humoral immunity of the offspring and as a result on the number of Trichinella larvae accustomed in the muscles. Immune interlayer formation in the populations of carnivorous mammals in the endemic areas occurs due to reinvasions and passive transmission of maternal antibodies to the offspring. High-tension immunity in the population and animals contributes to a reduction in the onset of invasion and to a predominance of the subclinical course of the disease and asymptomatic carriage in a specific focus. Passive immunity transmitted from the Trichinella-infected mother to its offspring is of importance in the development of epidemic and epizootic processes in the natural and synanthropic foci of trichinosis.
