Milk of Cow (Bos taurus), Buffalo (Bubalus bubalis), and Goat (Capra hircus): a Better Alternative than Fetal Bovine Serum in Media for Primary Isolation, In Vitro Cultivation, and Maintenance of Leishmania donovani Promastigotes
2007
Tyndalized milk of goat, cow, and buffalo was found to be a potential substitute for fetal bovine serum (FBS) in the medium for the cultivation of Leishmania donovani promastigotes. The numbers (means) of promastigotes reached 2.6 × 107, 2.3 × 107, and 2.1 × 107/ml, respectively, in the medium supplemented with 10% milk of goat, cow, and buffalo, in comparison to 1.9 × 107/ml in the control with 10% FBS. In primary isolation, the milk-supplemented medium showed that 22 out of 26 samples were positive for promastigotes (84.6%) and the cells were maintained successfully during the observed period of 6 months.
