摘要

Certain strains of Moraxella bovis produce tissue-damaging enzymes which may initiate or potentiate infectious bovine keratoconjunctivitis. Thirteen reference strains of this species were characterized physiologically and screened for production of various enzymes by some conventional biochemical tests and the API ZYM system (Analytab Products, Plainview, N.Y.). All 13 strains were hemolytic. All hydrolyzed Tween 80 and Tween 85 and displayed C4 esterase, C8 esterase-lipase, and C14 lipase activities. All produced phosphoamidase and phosphatase. All were able to hydrolyze casein and gelatin. All produced leucine and valine aminopeptidases and fibrinolysin. Twelve produced hyaluronidase or were agarolytic. Three hydrolyzed chondroitin sulfate. Nine strains autoagglutinated. Five produced catalase, and two produced cystine aminopeptidase.
