Homogenized biopsy tissue from the cutaneous leishmaniasis lesions of 50 patients from Trujillo, Venezuela, were inoculated subcutaneously into the tarsi of male hamsters. Homogenized tissue either alone or mixed with salivary gland lysates of Lutzomyia youngi were used for inoculation. Homogenized tissue alone yielded 58.5% of infections with a mean of twelve weeks for prepatency, while those mixed with sandfly lysate resulted in 92% of infections with a mean prepatency of three weeks.
