Cross-immunity trials in monkeys (Cebus apella apella) and observations on experimental and natural infections in man confirm the separate identity of L. mexicana mexicana, L. m. amazonensis, L. b. braziliensis, L. b. guyanensis and L. b. panamensis. Neither L. m. mexicana nor L. m. amazonensis infections gave protection against subsequent challenge with parasites of the L. braziliensis complex; but recovery from infection with subspecies of L. braziliensis in most cases gave firm resistance to infection with the mexicana parasites. The failure of certain New World leishmanias to immunize against each other has an important bearing on taxonomy, future attempts to prepare vaccines against Leishmania, epidemiology and diagnosis.
