Abstract

The development of genetic manipulation techniques has been reported in many protozoan parasites over the past few years. However, these techniques have not been established for Babesia microti. Here, we report the first successful transient transfection of B. microti. The plasmids containing the firefly luciferase reporter gene were transfected into B. microti by an AMAXA 4D Nucleofection system. Twenty-four-hour synchronization, the 5'-actin promoter, program FA100, and 50 μg of plasmid DNA constituted the best conditions for the transient transfection of B. microti. This finding is the first step towards a stable transfection method for B. microti, which may contribute to a better understanding of the biology of the parasite.
