Tubercle

Abstract: A hemagglutination reaction has been described between sheep erythrocytes treated with a component of a polysaccharide fraction of mammalian tubercle bacilli and the sera of experimental animals or of tuberculous patients. Evidence has been presented for the specificity of this reaction. A modification of the test, involving an inhibition reaction, has been developed for the detection and quantitation of minute amounts of the material responsible for the hemagglutination reaction.

Abstract: 1. Certain water-soluble esters of long chain fatty acids (in particular of oleic acid) favor submerged and diffuse growth of mycobacteria throughout the depth of synthetic liquid media. 2. Esters of oleic acid increase considerably the amount of growth yielded by avian strains in synthetic media. 3. The addition of serum albumin to synthetic liquid media permits visible growth of minimal inocula of virulent human tubercle bacilli (10(-8) mg.) within 11 to 15 days. 4. Cultures growing diffusely in media containing the water-soluble esters- with or without albumin-consist of cells of classical morphology and staining properties, which again exhibit the usual mode of growth when returned to the standard synthetic or egg yolk media.

Abstract: molecular systematics terminology and explains how phylogenetic relationships among species are inferred from molecular data. I wish every traditional taxonomist and systematist would read this chapter. This book contains a few misspellings (e.g., the chapter title in the Table of
