Sd. Coutinho et Cr. Paula, Proteinase, phospholipase, hyaluronidase and chondroitin-sulphatase production by Malassezia pachydermatis, MED MYCOL, 38(1), 2000, pp. 73-76
The production of four functional enzyme categories was investigated in 30
strains of Malassezia pachydermatis isolated from dogs with otitis or derma
titis. The most appropriate reading intervals for these assays were determi
ned with the aid of statistical comparisons. All strains produced proteinas
e and chondroitin-sulphatase; hyaluronidase and phospholipase were produced
by all skin isolates (15/15) and 14 out of 15 ear canal isolates. Strains
from ear canals did not differ significantly as a group from skin strains i
n quantitative production of any of the four enzymes; production of protein
ase and chondroitin-sulphatase in particular was markedly uniform.
