Plasmodium yoelii yoelii 33X is an uncloned isolate that showed resistance to chloroquine (LD50s not known).

The original isolate was taken from wild-caught Thamnomys rutilans 33X, also called 3L. Samples of this isolate were sent to London School of Hygiene and Tropical Medicine, then Edinburgh in January 1968. It was passaged into mice.

This item is host restricted and must be amplified in rodents.
