10. Appearance of thick and thin smear

13. DIAGNOSTIC POINTS Golden brown granules Black or dark brown Pigment P. vivax P. falciparum Spherical; compact Large; 12-18 merozoite; arranged irregularly Irregular, amoeboid Thick ring , often irregular one chromatin dot Schuffner's dots Amoeboid Enlarged Gametocyte Schizont Trophozoite Ring Stippling RBC Shape RBC Size Crescent shape Medium size; rarely seen in peripheral blood 19-32 merozoite Ring enlarged slightly irregular Fine ring, multiple infection 1-2 small chromatin dots Rarely, Maurer’s clefts can be seen. Round, sometimes crenated Not enlarged

16. DIAGNOSTIC POINTS P.OVALE P.MALRIAE Like P. vivax , but smaller Medium size; 8-14 merozoite arranged irregularly Round , compact Rings large and coarse, one chromatin dot. Black to brownish-black. Schuffner's dots Fimbriation Enlarged Similar to P. vivax , but smaller Small; 9-10 merozoite arranged as rosette Band forms are a characteristic of this species. Thick ring; one chromatin dot Dark black. Ziemann's dots, Elongation Not enlarged Gametocyte Schizont Trophozoite Ring Pigment Stippling RBC Shape RBC Size

21. MALARIAL PARASITE REPORTED IN LNH 2008

23. Malaria control Spry insecticides :(e.g. DDT ) Use mosquito nets, screen, or mosquito repellents to protect the person from mosquito bites. Reconstruction of environment: eradicate the breeding places of mosquitoes.
