Abstract
Lonomycin A at various concentrations was tested for its inhibitory effect on Toxoplasma multiplication in host cells cultured in vitro. Results indicated that lonomycin A at a concentration of 0.01μg per ml in TC-199 medium demonstrated a high degree of antitoxoplasma activity with complete inhibition of Toxoplasma multiplication in the host cells. Lymphokines, a supernatant produced from spleen cells of mice infected chronically with Toxoplasma gondii, inhibited Taxoplasma multiplication in mice macrophage and kidney cell monolayers. However, lonomycin A inhibited completely Toxoplasma multiplication in non-specific cells, i.e. not only in mice macrophages and kidney cells but also in cells of human and other animal species.
