Virulence and Morphological Characteristics of Mammalian Tubercle Bacilli
Experimental infection of the mouse can be used for the determination of virulence of cultures of mammalian tubercle bacilli. The relative virulence of such cultures for the mouse is approximately the same as for the guinea pig. Cultures of virulent and avirulent variants of mammalian tubercle bacilli grown in the depth of Tween 80-albumin liquid medium, on the surface of solid agar modificatio...
متن کاملBactericidal action of oleic acid for tubercle bacilli. II. Morphological response.
In the previous report (Minami, 1957), the bactericidal action of oleic acid on tubercle bacilli was studied, and it was concluded that some particular portion of the cell's surface structure was concerned with this action. In the present paper, the electron microscopic studies were carried out to look for a morphological base for the bactericidal action of oleic and other homologous fatty acid...
متن کاملTHE DETECTION OF Mycobacterium tuberculosis BY PCR IN SPUTUM SAMPLES FROM LONG-TERMTREATED LEPROSY PATIENTS: ASSOCIATIONS WITH SKIN TEST RESULTS AND IMMUNOTHERAPY WITH Mycobacterium vaccae
As part of a series of investigations at Baba Baghi Leprosarium in lran, 44 long-treated leprosy patients were selected for our study. Samples of early morning sputum were obtained from each patient, examined by microscopy for acid-fast bacilli (AFB), and cultured for tubercle bacilli. These tests were negative, but the polymerase chain reaction (PCR) for an insertion sequence believed to b...
متن کاملThe Prognostic Significance of Small Numbers of Tubercle Bacilli in the Sputum, Detected by the Concentration Smear Method *
The detection of tubercle bacilli in the sputum is regarded by many as of unfavorable prognostic significance, regardless of the number detected and the frequency with which they are found. This study is an attempt to evaluate the prognostic significance of small numbers of tubercle bacilli detected in the sputum by concentration methods. Sputum with modified Gaffky counts of i, ii, or iii were...
متن کاملOn the Response of Genetically Resistant and Susceptible Rabbits to the Quantitative Inhalation of Human Type Tubercle Bacilli and the Nature of Resistance to Tuberculosis
If genetically resistant and susceptible rabbits inhale a certain number of human type tubercle bacilli, no tuberculosis in the lungs of the resistant animals is seen, as a rule several months after infection, while there is a variable and often extensive disease in the susceptible rabbits. The analogy to the presence or absence of active tuberculosis in man infected with the tubercle bacillus ...
