Lipids of parasitic and saprophytic leptospires.
The lipid composition of five parasitic and six saprophytic leptospires was compared. Lipids comprise 18 to 26% of the dry weight of the cells after chloroform-methanol extraction. No residual (bound) lipid was found after acid or alkaline hydrolysis of the extracted residue. The total lipid was composed of 60 to 70% phospholipid, and the remaining lipid was free fatty acids. The phospholipid f...
متن کاملDifferentiation of Pathogenic and Saprophytic Leptospires with 8-azaguanine.
Johnson, Russell C. (University of Minnesota, Minneapolis), and Palmer Rogers. Differentiation of pathogenic and saprophytic leptospires with 8-azaguanine. J. Bacteriol. 88:1618-1623. 1964.-The use of the purine analogue, 8-azaguanine, as a differential agent for the separation of pathogenic and saprophytic leptospires was investigated. Growth of strains of the saprophyte Leptospira biflexa was...
متن کاملRapid method for the differentiation of parasitic and saprophytic leptospirae.
The differentiation of parasitic and saprophytic leptospirae may be of importance not only from a taxonomical point of view, but it can present a diagnostic problem in culturing strains from different materials, even from human specimens (Fuzi and Cs6ka, Zentr. Bakteriol. Parasitenk., Abt. I, Orig., 178, 222, 1960). The determination of pathogenicity for laboratory animals cannot be regarded as...
متن کاملParasitic and Saprophytic Abilities of the Nematode-Attacking Fungus Hirsutella rhossiliensis.
The ability of Hirsutella rhossiliensis to colonize various substrates in sterile and nonsterile soil was measured. Hirsutella rhossiliensis was recovered from 67% and 77% of living, inoculated Criconemella xenoplax incubated in sterile and nonsterile soil, respectively. In contrast, the fungus was recovered from 100% and 18% of heat-killed, inoculated nematodes incubated on sterile and nonster...
