Microbial Growth Stimulants in Spleen

Abstract

PREVIOUS studies have revealed that rabbit spleen contains unidentified, water-soluble substances that are growth stimulatory for Escherichia coli1, and also that beef spleen yields heat-resistant, water-soluble extractives stimulatory for species of pathogenic fungi2. A blood agar medium incorporating aqueous spleen infusion was formulated for the isolation of pathogenic fungi at 37° C.2. The stimulatory effects of spleen extracts on the growth of micro-organisms in chemically defined culture media has been investigated by us.
