Interaction of malarial infection and glucose-6-phosphate dehydrogenase deficiency in Muria gonds of district Bastar, central India.

Muria gond tribals (n = 473) from district Bastar, central India, an area known to be hyperendemic for malaria, were investigated for malarial infection and glucose-6-phosphate dehydrogenase deficiency. The frequency of G-6-PD deficiency was 21.3% among male subjects and 3.7% among females. Assay of malarial antibodies showed that seropositivity as well as the level of antibodies was significantly higher in male subjects with normal enzyme levels as compared with males G-6-PD deficiency. Females with normal G-6-PD enzyme levels too had higher seropositivity as well as level of antibodies against malaria as compared with females having G-6-PD deficiency. This suggests that G-6-PD deficiency correlates with a higher degree of resistance.
