GENETIC DIVERSITY OF THE MSP-1, MSP-2, AND GLURP GENES Of Plasmodium Falciparum IN THE CENTRAL OF SUMBA, EAST NUSA TENGGARA

Malaria is still a public health problem in Central Sumba regency, East Nusa Tenggara. Over the past decade, anti malaria drugs resistance has rapidly become a major public health problem in the East Nusa Tenggara, including Central Sumba regency. The problem of malaria control are not only influenced by the anti malaria drugs resistance on P. faciparum and specific genes but also by many variations of allele of Plasmodium malaria. A study is needed especially on molecular epidemiology of P. falciparum using locus gene Merozoites Surface Protein 1 (MSP 1), Merozoites Surface Protein (MSP2) and Glutamate Rich Protein (GLURP), which aims to identify the genetic diversity marker of Plasmodium falciparum in Central Sumba Regency. The method applied was a nested Polymerase Chain Reaction (PCR) to each locus gen separately. The results of the 50 fresh blood of patients infected with P. falciparum, each gene locus of MSP 1, MSP 2 and GLURP can be identified as much as 38%, 12% and 10%. The third gene locus was found only in 38 % (19/50) positive samples. It can be identified 7 alleles at each locus genes, three classes 'MSP1 allele (15.8 %), four classes of MSP alleles (21.1%) and three classes of GLURP alleles (15.8 %). A multigenotype infection of P. falciparum and MSP 2 deleted was diverse marker of P. falciparum gene locus with varied class of alleles. It can be concluded that multigenotype infections have occurred in research location.
