IFA serological surveys of malaria in north, north-west and south-west parts of Iran.
In the IFA serological surveys of malaria carried out in north, north-west and south-west parts of Iran during 1975-1982 altogether 9,132 subjects were studied for malaria antibodies and parasitaemia. Serological data indicated probable malaria transmission in a consolidation area where the autochthonous cases of malaria were reported a year after this serological study. Asymptomatic parasite carriers of P. malariae were found by IFA and parasite concentration techniques among the professional blood donors and the residents of a village without any recent malaria history. IFA results with P. falciparum antigen reflected the malaria histories in the studied areas of west Azerbaijan better than P. vivax antigen. The serological and parasitological findings in the nomads of Bakhtiary tribes showed that the nomads are more exposed to malaria infection in the winter quarters of Izeh area and they are also more under malaria control programme when they are living in this area. In comparison of IFA results of 438 paired plasma and dried blood samples tested with P. vivax and P. falciparum antigens, there was no significant difference between SPR in plasma and dried blood samples, however in the dried blood samples collected by malaria surveillance agents on filter paper SPR and GMRT were considerably low.
