Comparative study of the muramidase (lysozyme) activity in the blood cells of laboratory and agricultural animals

: Comparative studies have been carried out on the blood of certain laboratory and farm animals and birds, whereby the activity of muramidase (lysozyme) is established in neutrophilic cells of mice, guinea pigs, rats, rabbits, dogs, hens, turkeys and geese and in the monocytes of rabbits and dogs. The percentage of cells with muramidase activity manifests species features. No cells with a presence of muramidase activity have been found in the perypheral blood of cattle, sheep, pigs, goats, horses and bullalos. Certain questions of a general biological aspect about the origin of muramidase in the blood serum are examined on the basis of the results obtained and recent data from analyses of human blood.
