[An evaluation of methods of determining the hemolytic activity of Klebsiella in solid nutrient media].

Abstract

Hemolytic activities of Klebsiella-237 strains of various origins were measured in solid nutrient media by three methods making use of six different agar bases for the preparation of blood nutrient media. The authors analyze the agar bases, discuss the advantages and shortcomings of all the methods used with consideration for the purpose of the investigation. The findings evidence a higher hemolytic activity in Klebsiella isolated from patients as against the hemolytic activities of reference strains.
