[The effect of temperature on the growth of the promastigotes of different species of Leishmania].

The specific growth rate (r), the time of reduplication (T), reproduction rates (k) and the duration of the exponential phase (E) of L.major (L.m.), L.turanica (L.t.), and L.gerbilli (L.g.) are different from one another. It is shown that they differently depend on the temperature. Temperature has the greatest influence on L.g and the least on L.m. and its intermediate influence on L.t. The growth of long-term cultivation strains depends on the temperature than that short-term ones. It is associated with the adaptation rate of leishmania promastigotes to the growth in the nutrient medium. The optimum temperatures are defined for reproduction of the three species.
