Antibiotic Substances Separated from Sumac.

It has become evident (Osborn, 1943; Lucas and Lewis, 1944) that higher plants are potential sources of antibiotic agents. Several investigators (Little and Grubaugh, 1946; Atkinson and Rainsford, 1946; Sanders, Weatherwax, and McClung, 1945) have reported antibiotic effects of juices and of crude extracts of plants on various microorganisms. The active materials can be separated in some degree...

Microbial Antagonisms and Antibiotic Substances

alone and together, upon total heat production of normal rabbits, thryroidectomized rabbits, and thyroidectomized rabbits treated with thyroxin. Data so obtained were then supplemented with results of clinical studies, and from the whole, conclusions were drawn which are convincing, both because of the straightforward nature of the experiments themselves and the logical, orderly manner in which...

Antifungal Properties of Antibiotic Substances.

Fungi, especially the filamentous types, have become definitely established as the most important group of organisms that is capable of producing antibacterial substances under proper conditions of culture. No less significant, even if less well known, is the fact that many microorganisms, including fungi on the one hand, and bacteria and actinomycetes on the other, are capable of producing age...
