Expression of clumping and rosetting phenotypes of P.
falciparum clones and lines (ITO/A4, ITO/R29, ITO/C24, ITO/C10,
Palo Alto, Malayan Camp, and T9/96) in PPP (A) and in
PRP (B) containing approximately 1 ×
107 platelets per ml. Black bars and white bars represent
clumping and rosetting frequencies, respectively, of the corresponding
clones.
