[Fate of the promastigotes of Leishmania tropica major and L. gymnodactyli in the body of Phlebotomus papatasi under conditions of a mixed infection].
Experimental infection of males and females of Phlebotomus papatasi Sc. with Leishmania tropica major from man and L. gimnodactyli from Agama sanguinolenta was carried out in order to obtain mixed infection. Sand flies from the laboratory culture were successively infected with promastigotes of each species of Leishmania by means of compulsory dose feeding according to Alekseev's method. For identification of Leishmania cultures isolated from experimentally infected sand flies Alder's serological test modified by Safjanova was used. The mixed infection was obtained both in males and females of sand flies. The success of modelling of mixed infection depends on the succession of the administration of studied strains of Leishmania. It depends as well on the interval between infected feedings. The dependence of the experimental results on the number of promastigotes administered into the intestine of sand flies was not recorded.
