Abstract: Five species of human and domestic animal filariae ( B.m, S.d, S.l, S.e, D.i ) after lyophilization and hydrolysis were resolved using HPLC and type WFX IB AAS to determine amino acid (AA) and microelement (ME) content, respectively. The results showed that there were 16 and 17 AA in B.malayi and the animal filariae, respectively. Among AA, the total amount (μg/mg dry wt.) was markedly higher in animal filariae than that in B.malayi in which the content of acidic and aliphatic AA was significiantly higher than those of basic and aromatic AA, respectively. Among five ME (Zn, Cu, Fe, Mn, Cd) and two microelements (Ca, Mg) found in all these filariae. Zn Content was the predominant ME and Ca was much more than Mg.
