| Summary: | Ascaris suum metabolic antigens were obtained frorn second and early third stage larvae cultured in vitro in supplemented Eagle's minimum essential medium. Metabolic antigens harvested after 12 and 16 days from in vitro cultures were eluted through Bio-Gel Al.5. Three main elution peaks were identified, dialysed, lyophilized and injected into mice with 4% sodium alginate. Peak 11 from elution of two preparations of metabolic antigens protected mice against a chállenge infection of 10,000 A. suum embryonated eggs. |
