Transformation of the rodent malaria parasite Plasmodium chabaudi and generation of a stable fluorescent line PcGFPCON

<p>Abstract</p> <p>Background</p> <p>The rodent malaria parasite <it>Plasmodium chabaudi </it>has proven of great value in the analysis of fundamental aspects of host-parasite-vector interactions implicated in disease pathology and parasite evolutionary ecology. However, the lack of gene modification technologies for this model has precluded more direct functional studies.</p> <p>Methods</p> <p>The development of <it>in vitro </it>culture methods to yield <it>P. chabaudi </it>schizonts for transfection and conditions for genetic modification of this rodent malaria model are reported.</p> <p>Results</p> <p>Independent <it>P. chabaudi </it>gene-integrant lines that constitutively express high levels of green fluorescent protein throughout their life cycle have been generated.</p> <p>Conclusion</p> <p>Genetic modification of <it>P. chabaudi </it>is now possible. The production of genetically distinct reference lines offers substantial advances to our understanding of malaria parasite biology, especially interactions with the immune system during chronic infection.</p
