Resumo

Seventeen leeches obtained from armoured catfish (Hypostomus punclatus Valenciennes, 1840) infected with Trypanosoma spp. were examined. It was observed the presence of tripomastigotes, epimastigotes and amastigotes forms as well as dividing forms in the proboscis and in the stomach, different from the ones found in the vertebrate host as regards the morfometric features and developing forms. The examination of the contents of rectum did not show tripanosomes. These facts seem to demonstrate that Batracobdella gemmata (Blanchard, 1900) is an invertebrate host of trypanosomes and the transmission is done by means of inoculation.

The examination of the contents of rectum did not show tripanosomes. These facts seem to demonstrate that Batracobdella gemmata (Blanchard, 1900) is an invertebrate host of trypanosomes and the transmission is done by means of inoculation.
