ULTRASTRUCTURAL OBSERVATIONS ON Trypanosoma (Herpetosoma) rangeli IN THE SALIVARY GLANDS OF Rhodnius ecuadoriensis (Hemiptera, Reduvidae)

ULTRASTRUCTURAL OBSERVATIONS ON Trypanosoma (Herpetosoma) rangeli IN THE SALIVARY GLANDS OF Rhodnius ecuadoriensis (Hemiptera, Reduvidae)

An electron microscopy study was carried out on the salivary glands of the triatomine bug Rhodnius ecuadoriensis experimentally infected with a Peruvian strain of Trypanosoma (Herpetosoma) rangeli. Epimastigotes forms of T. rangeli were found in large numbers in the haemolymph surrounding the saliva...
