The Types of Pneumococci in Tuberculous Sputum
The success of Cole 1 and his associates 2 in establishing four groups among the pneumococci affords a new basis for the study of the transmissibility and pathology of acute lobar pneumonia. The most important result of this work is, perhaps, its bearing on the epidemiology of the disease. It has been generally accepted that the pneumococci of the normal mouth may, under favorable conditions, b...
متن کاملEVALUATION OF DIRECT MICROSCOPY, CULTURE, AND POLYMERASE CHAIN REACTION FOR THE DIAGNOSIS OF TUBERCULOUS MENINGITIS
In view of the importance of early diagnosis of tuberculous meningitis (TBM), the efficiency of the polymerase chain reaction (PCR), one of the most reliable and sensitive DNA-based assays, was compared with conventional methods (acid-fast microscopy and culture) for the detection of M. tuberculosis in cerebrospinal fluid (CSF) specimens from patients suspected of TBM. Of the 29 CSF specim...
متن کاملQuantitation of sputum protein by use of the biuret reaction.
A simple, accurate method is described for quantitatively determining the protein content of sputum by use of the biuret reaction. Fitteen mechanically homogenized specimens were examined with the biuret reagent described by Rosenthal and Cundiff, and the results compared with those obtained by the microKjeldahl technique. Over a range of 542 to 1917 mg of protein per 100 ml, the techniques cor...
متن کاملTuberculous Involvement of the Thyroid
Despite increasing detection rates of various forms of extrapulmonary tuberculosis (TB), thyroid involvement with tubercle bacilli is rarely encountered and its imaging features have been reported in less than a handful of cases. Herein, we present the clinical, pathologic and imaging (ultrasound and CT scan) features of TB involvement of the thyroid gland in a 65-year-old woman who presented w...
متن کاملCytological and Transcript Analyses Reveal Fat and Lazy Persister-Like Bacilli in Tuberculous Sputum
BACKGROUND Tuberculous sputum provides a sample of bacilli that must be eliminated by chemotherapy and that may go on to transmit infection. A preliminary observation that Mycobacterium tuberculosis cells contain triacylglycerol lipid bodies in sputum, but not when growing in vitro, led us to investigate the extent of this phenomenon and its physiological basis. METHODS AND FINDINGS Microscop...
