The Filtrable Phase of the Tubercle Bacillus

The Influence of Certain Organic Substances on the Growth of the Tubercle Bacillus

The power of a large number of aniline dyes to restrain the growth of Bacillus tuberculosis and Bacillus typhosus has been determined. Many substances have been found with especial restraining power for the tubercle bacillus under the conditions of the test. This capacity to restrain growth in the case of the tubercle bacillus apparently bears no simple relation to true disinfectant action. Opi...

The Branched Form of the Bacillus Tuberculosis in Sputum

The first * to draw especial attention to branching and budding forms of the tubercle bacillus were Nocard and Roux (1) in 1887. In the following year Metchnikoff (2) described and figured long, threadlike, branching forms with bulbous ends, observed in old glycerineagar cultfires cultivated at 43.6o-44 ° C. It is probable that these were cultures from avian tuberculosis. )/[etchnikoff suggeste...

Robert koch: centenary of the discovery of the tubercle bacillus, 1882.

This is an account of the life and work of Robert Koch (1843-1910), Nobel Laureate in Medicine and a founder of the science of bacteriology. In particular, Koch's researches into tuberculosis are described - the discovery of the tubercle bacillus, the controversy regarding the human and bovine types, the Koch phenomenon, and the introduction of tuberculin, which proved to be ineffective as a cu...

Further Studies on the Survival Time of the Bovine Tubercle Bacillus in Soil, Soil and Dung, in Dung and on Grass, with Experiments on Feeding Guinea-pigs and Calves on Grass Artificially Infected with Bovine Tubercle Bacilli.

Medical Research Council. Special Report Series No. 259. 'The Murine Type of Tubercle Bacillus (The Vole Acid-Fast Bacillus)'

In 1937 Dr. A. Q. Wells discovered an acid-fast bacillus giving rise to a disease in voles which he described as tuberculosis. Though it was regarded by some as a form of leprosy, further investigations showed that his description of the disease was essentially correct. The first part of the present report written by Dr. Wells himself, deals with the morphology, culture and pathogenicity of the...
