Comparison of three blood-clotting substances in Staphylococcus aureus strains

Plasma was used from rat, mouse, guinea pig, rabbit, dog, cat, sheep, goat, monkey, horse, pig, cow, fox, mink, porpoise, deer, manatee, seal, elephant, raccoon, pigeon, macaw, and humans; clotting time and gel formation activities by the compact-colony forming active substance (CCFAS) extracted from a strain of Staphylococcus aureus and relative staphylococcal clumping factor reaction were determined. Experimental results showed that every plasma was clotted and gel formation of plasma was observed by the CCFAS, however, although it was shown by the other plasmas, no clumping-factor reaction was observed with plasma from guinea pig, goat, and elephant.

Using 20 strains of Staphylococcus aureus isolated from clinical specimens, the compact colony-forming activity (CCFA) in serum-soft agar (SSA) in sera from various animals and the paracoagulation (PC) activity of the compact colony-forming active substance (CCFAS) extracted from these strains were investigated. The results of this comparative study revealed that the CCFA and PC of S. aureus for sera from various animals in SSA were different, not only among different strains but also in the same strains. In addition, the effect of galactose and calcium ions on the PC activity of these strains in experiments employing human fibrinogen permitted the recognition of these groups of S. aureus strains. In one group, PC activity was decreased by galactose but unaffected by calcium ions, in the second group PC activity was unaffected by galactose but increased by calcium ions, while in the third group it was unaffected by both. These results suggest the possibility of heterogeneity of CCFA among different strains of S. aureus.
