means of obtaining diagnostic evidence of malarial infection, viz.?{a) detection of the malarial parasites; (&) detection^ of malarial pigment in the leucoc^ tes , (c) detection of change in the proportion of the large mononuclear leucocytes; the last two methods are of special value where the administration of quinine has driven the parasites from the peripheral circulation ; this subject Capt...

In the tropics, helminths are among the most common chronic infections of humans and Plasmodium infections the most deadly. As these two groups of parasites have similar geographical distributions, co-infection is commonplace. It has increasingly been speculated that helminth infections may alter susceptibility to clinical malaria, and there is now increasing interest in investigating the conse...

A specific agglutination of Plasmodium knowlesi detectable both by macroscopic and by microscopic methods is described. Agglutinins for Plasmodium knowlesi appear in the sera of monkeys between 15 and 45 days after the onset of the infection and become progressively stronger as the malarial infection gradually subsides. Agglutinins persist in the sera of chronically infected animals for a year ...

Plasmodium elongatum, an avian malarial parasite, differs from other such parasites by infecting both the circulating red blood cells and the hematopoietic cells. The exoerythrocytic development of P. elongatum occurs mainly in these red cell precursors. The fine structure of the asexual stages of P. elongatum has been studied in the bone marrow and peripheral blood of canaries and compared wit...

as powerful antimalarial agents. The work carried out in the School of Tropical Medicine, Calcutta, on the action of these drugs on the Indian strains of malaria parasites is in accord with findings obtained in other parts of the world. Plasmoquin has been tried by a large number of workers, and in India, Napier, Butcher and Das Gupta (1932) used it with success in their field experiments. Ateb...

OF a total of 833 medical cases of pyrexia investigated among the garrison of Sierra Leone during the period October 4, 1912, to October 4, 1913,' 623, or roughly three-quarters, were proved microscopically to have been malarial in origin. These figures are sufficient to show the overwhelming preponderance of this disease on the West Coast of Africa, and are supported by a collateral investigat...

A survey of asymptomatic children in Uganda showed Plasmodium malariae and P. falciparum parasites in 45% and 55% of microscopy-positive samples, respectively. Although 36% of microscopy-positive samples were negative by rapid diagnostic test, 75% showed P. malariae or P. ovale parasites by PCR, indicating that routine diagnostic testing misses many non-P. falciparum malarial infections.
