(nematoda: Tetrameridae) in Meadowlark

Pathogenicity of adult and third-stage Microtetrameres centuri Barus, 1966 in meadowlarks (Sturnella spp.) is reported for the first time. Adults do not encyst; their effects are mainly mechanical.

(Nematoda): Purification and Characterization

Copper-zinc superoxide dismutase from Ascaris suum (Nematoda) was purified in a new, more efficient, and faster manner. The process included differential centrifugation, fractionation with ammonium sulfate, and sodium dodecyl sulfate-polyacrylamide electrophoresis, yielding a 340-fold purification (specific activity of 47 units/mg). Optimal storage conditions, optimal pH range, thermostability,...
