: Infections caused by Trypanosoma brucei, Trypanosoma cruzi, Leishmania spp., Entamoeba histolytica, Giardia lamblia, Plasmodium spp., and Trichomonas vaginalis, are part of a large list of human parasitic diseases. Together, they cause more than 500 million infections per year. These protozoa parasites affect both low- and high-income countries and their pharmacological treatment is limited. Therefore, new and more effective drugs in preclinical development could improve overall therapy for parasitic infections even when their mechanisms of action are unknown. In this review, a number of heterocyclic compounds (diamidine, guanidine, quinoline, benzimidazole, thiazole, diazanaphthalene, and their derivatives) reported as antiprotozoal agents are discussed as options for developing new pharmacological treatments for parasitic diseases.

Study of protozoyny invazions of the uroganital system with combination of microorganisms which are associated with bacterial vaginosis by women of fertil age and their sexual partners men is perspective direction of modern medicine. The development of this direction can increase the level of diagnostic inspection of patients by transmissible mainly sexual way infections and improve of efficiency of their treatment. The objective: exposure of combine defeats of uroganital system with different kinds of trichomonas or lamblias and microorganisms which are associated with bacterial vaginosis, for the women of fertil age and their sexual partners – men. All patients have infections, transmissible mainly sexual way with a chronic process and their treatment. Materials and methods. The special research of biomaterial, taken from the urogenital system of women of fertil age and their sexual partners-men, patients infections, transmissible mainly sexual way with a chronic process is conducted. 198 patients were inspected in clinic. Used the method of PCR, amplifier of DT-96, reagents of «Femoflor-16», praymeris for the indication of Trichomonas vaginalis, Trichomonas tenax, Pentatrichomonas hominis and Giardia lamblia. Results. Protozoyny invasions of the urogenital system determined at 88 (44.4%) of patients. At 77 (38.8%) from them determined the differet kinds of trichomonadies: Trichomonas tenax – at 41 (20.7%), Pentatrichomonas hominis – at 28 (14.1%), Trichomonas vaginalis – at 8 (4%). Giardia lamblia determined from 11 patients (5.6%). For 92% inspected patients with a protozoal invasions were determined the increassng of indexes of microflora, associated with bacterial vaginosis. The treatment of combine pathology of urogenital system which are caused different kinds trichomonades and microorganisms, which associated with BV, were conducted with etiotropic therapy. Seknidox used 2 tablets one time per day during 5 days. Orcipol used 1 tablets 3 or 2 times per a day (depending on weight) during 10 days. In research took part 56 patients with chronic ITSW. By 54 patients (96.4%) were eliminated of trichomonas. The normalization microflora’s level is attained for a 31 (57.4%) patient. Decrease of mocroflora’s, which associated with BV is marked by 24 patients (42.6%). Conclusions. This original method of treatment, is effective, has satisfactory bearableness and can be recommended for empiric therapy of combined pathology of urogenital system, caused of protozoyny invasions (different kinds of trichomonas) and microorganisms, associated with bacterial vaginosis, for the women of fertil age and their sexual partners with chronic infections, transmissible mainly sexual a way. This agents have a certain role in development of diseases of the urogenital system. Key words: Trichomonas vaginalis, Trichomonas tenax, Pentatrichomonas hominis, Giardia lamblia, invasion, fertil age.

Background: There is an increasing interest in using physical factors such as magnetic fields as antimicrobial strategy, with variable results. The current study was aimed to evaluate the influence of extremely low-frequency electromagnetic fields (ELF-EMFs) on the axenically-cultured parasite protozoans Trichomonas vaginalis and Giardia lamblia growth. Methods: Bioassays were developed using T. vaginalis, GT-13 and G. lamblia IMSS-0989 strains cultured at 37 ºC in TYI-S-33 medium. The following treatment regimens and controls were considered: (a) cells exposed to ELF-EMFs, (b) untreated cells, (c) cells treated with Metronidazole, used as positive controls, and (d) cells co-exposed to ELF-EMFs and Metronidazole. When cultures reached the end of logarithmic phase, they were exposed to ELF-EMFs for 72 h, in a standardized magnetic field exposure facility. For determining cytotoxic effects, trophozoite density was blindly evaluated in a Neubauer chamber. Results: A significant decrease in trophozoite growth was observed for T. vaginalis, in magnetic field-treated cultures. On the other hand, cultures co-exposed to ELF-EMFs and Metronidazole showed no significant differences when compared with cultures treated with Metronidazole alone. On the contrary, an increased trophozoite density was observed in G. lamblia cultures after exposure to magnetic fields. An absence of a synergistic or antagonistic effect was observed. Conclusion: ELF-EMFs induced T. vaginalis and G. lamblia growth alterations, indicating a potential effect in cell cycle progression.
