50 µl of sera samples from rBmHAT immunized macaques or control macaques were incubated with 2×105 PBMC from naive macaques and 10 B. malayi L3 for 48 hrs at 37°C. Larval viability was evaluated at the end of the incubation.
Significant larval death **(P<0.05) compare to other macaques. Control wells were L3 incubated with media, cells alone or sera alone.
