American trypanosomiasis in British Honduras. V. Development of Trypanosoma (Schizotrypanum) cruzi in animals infected with strains isolated in the El Cayo District, and the occurrence of crithidia forms in the tissues

ABSTRACT

The morphology is described of the tissue stages of Trypanosoma cruzi observed in strains isolated in British Honduras. The persistent presence of crithidia forms of the parasite in infected vertebrate tissues suggests that T. cruzi strains found in British Honduras differ from strains described from other geographical areas. It is suggested that such strains may be suitable for studies on trypanocidal drugs in vivo and for comparative studies on the morphology of reproduction in tissues. (AU)
