摘要
SYNOPSIS. Twelve strains of Crithidia, which fall into 8 species, were tested for occurrence of enzymes of ornithine‐arginine metabolism. The following enzymes were investigated: arginase, ornithine carbamoyltransferase, argininosuccinate lyase, citrulline hydrolase, arginine deiminase and urease. Arginase and argininosuccinate lyase were found in all species. Citrulline hydrolase was also found in all but the 2 strains carrying endosymbiotes C. deanei and C. oncopelti. On the other hand, ornithine carbamoyltransferase was found only in these 2 strains. Arginine deiminase and urease were absent in all strains. The existence of a common enzymatic pattern for species of the genus Crithidia is thus reported. Copyright © 1978, Wiley Blackwell. All rights reserved
