Pulmonary Tuberculosis, Etiological and Therapeutic

چکیده
phthisis is simply bronchitis for many months, and then becomes tuberculous by inoculation into a suitable soil. Doubtless tuberculous mischief may exist in the lung for l?ng periods anterior to the manifestation of catarrhal symptoms, and at the very earliest stage of many cases, even anterior to the manifestation of physical signs of disease in the lung, the sputum may be found to contain multitudes of bacilli. On the other hand, the chronic catarrhal patients, with bronchitis recurring for many years, emaciated and apparently an easy prey to bacillary disease, may live an indefinite time, and escape tubercular inoculation altogether. Catarrhal processes are a very importantpart of the phenomena of phthisis, but we are inclined to look upon the invasion of the bacillus as the first stage and the catarrh as a secondary product.
