Sero-epidemiological survey of malaria by immunofluorescence in Pakistan (District Gujranwala-Punjab).

Indirect Immunofluorescence Antibody (IFA) Technique was employed, for field detection of malarial parasite. The technique involved application of homologous antigen slides of Plasmodium falciparum and P. vivax prepared in the field conditions. Serological study, simultaneously using P. falciparum and P. vivax antigens, brought out a clearer picture of distribution and role of the parasite species in the epidemiology of the disease in the area studied. The survey supported the contention of persistence of transmission of malaria in Gujranwala District.
