Ultrastructural alterations of intracellular stages and effects on blood forms of Trypanosoma cruzi induced in vivo by 2-amino-5-(1-methyil-5-nitro-2-imidazolyl)-1,3,4 - Thiadiazole
An electron microscopy study shows that the administration of a single dose (500 mg/kg, p.o.) of 2-amino-5-(1-methyl-5-nitro-2-imidazolyl)-1, 3, 4-thiadiazole induces in mice infected with Trypanosoma cruzi results in degenerative lesions of the intracellular stages. Ultrastructural alterations are...

| Summary: | An electron microscopy study shows that the administration of a single dose (500 mg/kg, p.o.) of 2-amino-5-(1-methyl-5-nitro-2-imidazolyl)-1, 3, 4-thiadiazole induces in mice infected with Trypanosoma cruzi results in degenerative lesions of the intracellular stages. Ultrastructural alterations are detected as early as 6 hours after the drug administration and destruction of the parasites occurs within 18 - 36 hours. Trypomastigotes are cleared from the bloodstream 4 to 6 hours after treatment. The combined effect on both developmental stages is apparently responsible for the in vivo ejfects of this drug which is the most active drug ever tested in our laboratory in experimental Chagas' disease. |
