Question

Assertion: plasmodium vivax is responsible for malaria

Answer 1

P. vivax can cause severe malaria.Haematological morbidity associated with P. vivax infection is greatest in young children, especially in tropical countries where transmission is intense and local parasite strains relapse very frequently (Douglas, 2012). severe anemia and thrombocytopenia that causes bleeding diathesis is produced by hemolysis, reduced cell deformity of parasitized and nonparasitized erythrocytes, increased splenic clearance, reduction of platelet survival, decreased platelet production, and increased splenic uptake of platelets, and can be produced by P. vivax and P. falciparum infection (Luxemburger et al, 1997).

Answer 2

Plasmodium vivax. Plasmodium vivax is a protozoal parasite and a human pathogen. This parasite is the most frequent and widely distributed cause of recurring (Benign tertian) malaria, P. vivax is one of the five species of malaria parasites that commonly infect humans.
