Cytochemical detection of carbohydrates in the Golgi complex of Leptomonas pessoai.

Using the periodic acid-thiosemicarbazide-silver proteinate technique, a positive reaction was observed on the membranes of the Golgi complex of Leptomonas pessoai. A positive reaction was also observed in other cytoplasmic membranes located near the Golgi complex. Structures which could represent reserve polysaccharides were not observed in the cytoplasm of Leptomonas pessoai.
