The minimum standard suggested for declaring a patient negative is that on discharge no tubercle bacilli should be foun...
متن کاملAutomated identification of tubercle bacilli in sputum. A preliminary investigation.
OBJECTIVE To use an automated method to detect tubercle bacilli in sputum specimens. STUDY DESIGN Using fluorescence microscopy, tubercle bacilli were identified on auramine-stained sputum specimens. Images were then captured with a digital camera and enhanced through imaging processing techniques. The bacilli were recognized using neural network classifiers. RESULTS This preliminary invest...
متن کاملSurvival of tubercle bacilli in heat-fixed sputum smears.
Tubercle bacilli, which survived heat fixation, were detected with a slide culture technique which allowed the entire smear to be examined. Both conventional flame fixation and the use of a controlled hot-plate failed to render tuberculous sputum smears safe for further handling. Smears which were stained with the phenol-auramine method failed to yield growth on culture. If delay between prepa...

The absolute identity of tubercle bacilli infecting mammalia has bee~ so generally assumed and the assumption used as a basis for the enactment of sanitary measures having for their object the prevention of any transmission of tubercle bacilli from animals to man, that any one who would attempt to question this identity must be prepared to meet considerable scepticism. Taking a broad biological...
