title: Identification of an infective stage of Leishmania promastigotes.
abstract: Sequential development of Leishmania promastigotes from a noninfective to an infective stage was demonstrated for promastigotes growing in culture and in the sandfly vector. The generation of an infective stage was found to be growth cycle-dependent and restricted to nondividing organisms.
