THE DETECTION OF THE BACILLUS TUBERCULOSIS, TECHNIQUE.

THE DETECTION OF THE BACILLUS TUBERCULOSIS, TECHNIQUE. The form of the bacillus tuberculosis is not characteristic, and it cannot, therefore, be differentiated from other pathogenic and non-pathogenic bacteria by its form alone. It is a very thin bacillus, about 2 to 5 micromillimetres in length (from one-quarter to one-half the diameter of a red blood-corpuscle). It is usually slightly bent. Like all protoplasmic cells it has an affinity for the aniline colors, and its reaction to these colors is characteristic when the aniline is combined with a mordant. To elicit the characteristic reaction of the bacillus to the aniline colors it is necessary to proceed in a methodical manner. The instruments used, forceps, needles, etc., should be clean, sterilzed by heating in a gas or other flame. The cover-glasses and slides should be cleansed in fine alcohol. The material supposed to contain the bacilli should be collected in a clean vessel, and when collected should be protected http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png JAMA American Medical Association

Abstract

The form of the bacillus tuberculosis is not characteristic, and it cannot, therefore, be differentiated from other pathogenic and non-pathogenic bacteria by its form alone. It is a very thin bacillus, about 2 to 5 micromillimetres in length (from one-quarter to one-half the diameter of a red blood-corpuscle). It is usually slightly bent. Like all protoplasmic cells it has an affinity for the aniline colors, and its reaction to these colors is characteristic when the aniline is combined with a mordant. To elicit the characteristic reaction of the bacillus to the aniline colors it is necessary to proceed in a methodical manner. The instruments used, forceps, needles, etc., should be clean, sterilzed by heating in a gas or other flame. The cover-glasses and slides should be cleansed in fine alcohol. The material supposed to contain the bacilli should be collected in a clean vessel, and when collected should be protected
