Coenzyme A requirement of malaria parasites: enzymes of coenzyme A biosynthesis in normal duck erythrocytes and erythrocytes infected with Plasmodium lophurae.

Normal duck erythrocytes and erythrocytes infected with Plasmodium lopharae have all of the enzymes for coenzyme A biosynthesis, whereas parasites freed from their host cells have non. Since erythrocytefree cultivation of P. lophurae requires an exogenous source of coenzyme A, this parasite must obtain its coenzyme A entirely from the host cell during infection.
