摘要:

SUMMARY1.Three cultures ofLipomyces Starkeyiwere isolated from the skin of three different persons. These are the first isolations of any species of the genus recorded from a habitat other than the soil.2.Lipomyces lipoferusLod.&Rij is considered to be a synonym ofLipomyces StarkeyiLod.&Rij.3.All six cultures ofLipomyces Starkeyistudied (including the type strain ofL. lipoferus, here reduced to synonymy withL. Starkeyi) produced a“starch-like”substance from glucose, like that produced by all species of the genusCryptococcus. This might indicate a phylogenetic relationship between the perfect genusLipomycesand the imperfect genusCryptococcus.

摘要:

SUMMARYA new species ofStreptomyces, S. albo-niger, which produces the antibiotic puromycin, has been described. Its taxonomic relationships are discussed, as well as a simple, direct method of studying the morphology of the aerial growth of it and other Streptomyces.

摘要:

SUMMARYThis investigation is concerned with the determination of the toxicity of a number of species ofAmanitato guinea pigs.Alcoholic extracts ofA. chlorinosma, A. cothurnata, A. flavivolva, A. mutabilis, A. neglecta, A. praegraveolens, andA. roanokensiswere injected subcutaneously into guinea pigs without the appearance of any symptoms. It is concluded that these species are not-toxic by this method of testing.Alcoholic extracts ofA. verna, A. verniformis, andA. virosi-formiswere injected subcutaneously into each of two guinea pigs, resulting in the death of both animals in each case within forty-eight hours. Autopsies were performed upon these animals, and the gross pathological changes noted include failure of the blood to clot, hemorrhage of the intestinal tract, anuria, and extensive pin-point hemorrhages of the liver.The symptoms indicate the presence ofAmanita-toxinin each of these species. The rapid onset of symptoms and paralysis noted in the animals injected withA. verniformissuggests the presence in this species of an additional toxic principle affecting the central nervous system.
