Widal agglutination test reaction in patients with fallciparum malaria

ABSTRACT

Serum samples from 115 patients with falciparum malaria who attended Tharyarwady Civil Hospital during summer and rainy seasons of 1991 were studied. Of these, 71 patients were followed at Day (7) of admission to the hospital. the sera were tested by tube agglutination for antibodies against H and O suspension of enteric fever organisms (Salmonella typhi, Salmonella paratyphi A and Salmonella paratyphi B). 3 samples of sera collected from patients with parasite density (1+) and suffering from uncomplicated malaria showed agglutination titre + 1/40 to 0 and H antigens of Salmonella typhi. One serum sample collected from a patient with parasite density (2+) and suffering from uncomplicated malaria showed agglutination titre + 1/40 to 0
