FINE STRUCTURES OF LEISHMANXA PARASITES FROM RACOON DOG

The fine structures and electron scanning of Leishmania amastigotes and promastigotes isolated from a naturally infected racoon dog (Nytereutes pro- cyonoides Gray) in the suburbs of Beijing were stu- died and compared with those of a Chinese human strain. They were much similar in fine structures in a number of subpellicular microtubules and in the distance between 2 microtubules. We consider that it may belong to the category of L donovani complex. A kind of multi-vesicular body has been seen in the cytoplasm of amastigotes of both strains but its nature needs further study.
