Infectivity of Leishmania donovani amastigotes and promastigotes for golden hamsters

J S Keithly. J Protozool. 1976 May.

Abstract

Intracardial injection of hamsters with from 5 to 114 million amastigotes or promastigotes of Leishmania donovani and screening of the 8th-day liver impression smears, provides a rapid and reproducible method for assaying infectivity. Amastigotes are at least 10X more infective than promastigotes, and log-phase promastigotes act as a single infective population for hamsters.
