Claim 1: “both have shown potent activity against malaria and babesiosis parasites, including drug-resistant strains.”

SINGLE SOURCE

The evidence provided in the search results for Claim 7 mentions that these compounds could 'counter drug-resistant malaria', but there is no independent second source confirming the specific 'potent activity' against both malaria and babesiosis drug-resistant strains.

Claim 3: “Both diseases are caused by closely related parasites that invade red blood cells”

VERIFIED

Evidence from Wikipedia and CDC confirms both malaria and babesiosis are caused by parasites that infect red blood cells. Biological classification (Apicomplexa) confirms they are closely related.
