Efficacy of alkaloid (-)-corypalmine against spore germination of some fungi.

abstract：:Microorganisms in the midgut and rectum of the honeybee were enumerated and characterized. Counts of aerobic microorganisms were distinctly lower than counts of anaerobes (10(5)-10(6) viable cells per g of intestinal content vs. 10(8)-10(9) per g). Total numbers of anaerobic microorganisms were almost identical with t...
