Preservação de ovos de helmintos e cistos de protozoários em iodomercurato de potássio. Revisitando experimentos realizados há cerca de 40 anos / Preservation of helminth eggs and protozoan cysts in potassium iodinemercurate. Revisiting experiments carried out about 40 years ago
A reassessment was carried out on the preservation status of helmintheggs and protozoan cysts maintained for about 40 years in 0.2% potassiumiodinemercurate solution. It was observed that Schistosoma mansoni, Ancylostomidae and Trichiuris trichiura eggs and Isospora belli oocysts were kept in conditions suitable for their identification under a common light microscope. In the examined material, it was possible to verify the presence of miracidium in S. mansoni egg, larvae in T. trichiuraegg and sporozoites in I. belli oocysts. (AU)
