RESUMO

Cystoisospora felis is an obligatory intracellular parasite that infecting felines of diverse species, that were contaminated by ingesting sporulated oocysts end/or intermediated host harboring monozoic cysts of this species. In this study, 10 Japanese quails were infected with a pure inoculum consisted by 106 sporulated oocysts of C. felis, after 60 days post infection, liver, spleen, and bursa of Fabricius were removed from each quail and they were given to feed to 3 kittens separately. A forth kitten was infected with 106 sporulated oocysts orally. After shedding oocysts by kittens, they were allowed to sporulate. After that, 50 sporulated oocysts of each infection were measured, having as means of Length, Width and Shape Index the following values: 44.302.30, 31.301.90 μm and 1.400.1 from kitten fed on liver, 46.302.20, 32.901.90 μm and 1.400.1 from kitten fed on spleen, 44.802.20, 31.201.60 μm and 1.400.1 from kitten fed on bursa of Fabricius, and 43.601.60, 30.801.60 μm and 1.400.1 from kitten infected with sporulated oocysts orally as well as C. felis prepatent and patent periods. By analyzing the frequency of the distribution of values was observed that when the source of infection were liver and spleen, the distribution was more homogeneous, which did not occur when was used cloacal bursa or sporulated oocysts as sources of infection. As conclusions in this work, there were no significant differences among de morphometry of the sporulated oocysts, independent of the source of infection. Moreover, the pre-patent and patent were similar when cats fed on infected viscera of quails experimentally infected with sporulated oocysts of C. felis previously when compared with the animal that received 1x106 sporulated oocysts orally.
