Detection of human malaria using recombinant Plasmodium knowlesi merozoire surface protein-1 (MSP-119) expressed in Escherichia coli

- Recombinant Plasmodium  knowlesi MSP-119 was cloned and expressed in Escherichia coli.
- rMSP-119 was evaluated in immunoblots.
- rMSP-119 was able to detect most of the antisera in malaria-infected samples.
- rMSP-119 has a 100% specificity.
- It could be used for serodiagnosis of malarial infection.
