Amino acid residues D24/D25, E99/E100, E360/E361, and D363/E364 in subdomain 1 of Dictyostelium actin were replaced with histidine residues by site-directed mutagenesis. Mutant actins were expressed in Dictyostelium cells and purified to homogeneity. The sliding movement of mutant actin filaments on heavy meromyosin attached to a glass surface was measured(More)
The effectiveness of an oil adjuvant vaccine (OAV) incorporating locally isolated strains of Pasteurella haemolytica type 7 and Pasteurella multocida types A and D was compared with that of Carovax (Wellcome Laboratories) in imported cross-bred lambs. The criterion of efficacy was the ability of the vaccines to reduce the extent of pneumonic lesions in(More)
