Abstract

Objective: It was aimed to assess the success of the cryopreservation process which is carried out in order to preserve the genetic material and the virulence of the Leishmania species that are an important health problem in our region.

 

Methods: Leishmania tropica, L. infantum, L. major, and L. donovani strains in Novy-MacNeal-Nicolle (NNN) medium in MCBU were used. Promastigotes cultured in the NNN medium were transferred to RPMI 1640 medium; promastigotes in the logarithmic phase were washed three times with PBS, and 15% dimethylsulfoxide (DMSO) was added. Leishmania species were transferred to 12 separate tubes. The tubes were stored at −86°C for one night by placing them in Coolcell boxes. The tubes were transferred into a liquid nitrogen tank. One cryotube per Leishmania strain is thawed monthly and cultured in NNN medium.

 

Results: For the duration of study it was observed that each Leishmania isolate preserved 60-65% of their viability and entered the logarithmic phase on the 7th day following the inoculation in the NNN medium. Abnormalities in the structures and movements of the promastigotes were not observed in microscopic examinations.

 

 

Conclusion: The following conclusions were made: cryopreservation is important for studies planned related to leishmaniasis and cryopreservation with DMSO is successful.
