ОСОБЕННОСТИ ЭКОЛОГИЧЕСКИХ ВЗАИМОДЕЙСТВИЙ МЕЖДУ ПРЕДСТАВИТЕЛЯМИ КЛАСА ПАПОРОТНИКОВИДНЫЕ И ПАТОГЕННЫМИ ЛЕПТОСПИРАМИ В УСЛОВИЯХ ПЕРЕУВЛАЖНЕННЫХ ЗЕМЕЛЬ

Прижизненные выделения (дифузаты корневищ и смывы с листьев) щитовника мужского и телиптериса болотного угнетают в сильной и умеренной степени in vitro культуры патогенных лептоспир серологического варианта Icterohaemorrhagiae. Вещества, выделенные из мертвых листьев, обозначенных видов папоротников так же имеют токсическое влияние на спирохет, но в меньшей степени. Участки переувлажненных земель, на которых произрастают представители класса папоротниковидные есть неблагоприятными для длительного существования патогенных лептоспир Leptospira interrogans серовара Icterohaemorrhagiae

Ключевые слова: телиптерис болотный, щитовник мужской, патогенные лептоспиры, прижизненные выделения, продукты распада (разложения)

PECULIARITIES OF ECOLOGICAL INTERACTIONS AMONG REPRESENTATIVES OF CLASS POLYPODIOPSIDA AND PATHOGENIC LEPTOSPIRES IN THE CONDITIONS OF WETLAND TERRITORIES

Natural hearths of leptospirosis disease are confined to freshwaters and adjacent areas of wetlands. Dryopteris filix-mas L. and Thelypteris palustris L. are widespread spesies which belong to class Polypodiopsida. We investigated the influnce of lifetime secretes and substances which were received from decomposed dead leaves of ferns on cultures of pathogenic leptospires (serological variant Icterohaemorrhagiae). We received ablutions from alive leaves of ferns by the imitation of light rain. Diffusion substances of rhizomes were received from specimens of ferns which were kept in water containers where plants healed parts of damaged roots. Allelopathic activity of plants regarding pathogenic leptospira was tested at a dilution of 1: 1000. Inoculums of spirochetes culture were chosen from one culture. That provided equal initial contents of spirochetes in research’s and controls groups. The samples were stored at 18 - 20 degrees above 0 in laboratory. Spirochetes contents in the experimental samples were determined and compared after 24 hours. Lifetime secretes (diffusions substances of rhizomes and washing from alive leaves) of D. filix-mas and T. palustris repress in vitro cultures of pathogenic leptospires (serological variant Icterohaemorrhagiae). Substances which were received from decomposed dead leaves of ferns had a toxic influence on spirochetes, but to a lesser extent. Parts of wetland territories, where species of class Polypodiopsida grow adverse for long-term existence of pathogenic leptospires (serological variant Icterohaemorrhagiae).
