[Determination of the bacteriocidal activity of the blood serum and lymph]

A microbiologic method for measurements of the blood serum and lymph bactericidal activity with the use of the test system with Bac. subtilis spore suspension and agar dosed for the nutrient and growth substances is suggested for clinical practice. These activities have been measured in patients with mammary carcinomas during surgical treatment; the levels of nonspecific antibacterial defense factors of the body have proved to be sufficiently high.
