| description | Purpose.The object of investigation constituted the influence of vital plant discharges of C. demersum on the pathogenic bacteria population density.
Methodology. Aqueous solutions secretions of C. demersum were sterilized by vacuum filtration through the filters with pore diameter of 0,2 microns. After adding E. rhusiopathiae or L. interrogans, the samples under study contained the secretions of C. demersum fluitans in 1:10, 1:100, 1:1000 and 1:10000 dilutions. As a method of control, sterile water from the water supply was used in a volume similar to the samples, in which the same amount of bacterial was added. After a 48-hour exposure, the test samples were taken to determine the density of bacterial populations. The discharges of C. demersum in dissolution 1:10 and 1:100 stimulated the growth in population E. rhusiopathia bacteria. In the following dissolution 1:1000, 1:10000 any considerable influence on the bacteria population hasn’t been noticed.
Findings. Under influence of dissolution of C. demersum, the density of the L. interrogans population in the investigated serological variants varied. Under natural conditions a topical type of biocoenotic relations is being formed between plant and bacteria.
Originality. Environmental relations of E. rhusiopathiae and L. interrogans with water plant C. demersum have been studied for the first time.
Practical value. E. rhusiopathiae and L. interrogans bacteria are able to cause human and animal diseases, penetrating into their organisms from ground and water. To some extent, the lifespan of erysipelothrixes and leptospira in water depends on the ecological relationships with various components of phytocenoses, including plants C. demersum. |
