Gram stain evaluation of the quality of sputum specimens for mycobacterial culture.
A group of 34 mycobacteria, consisting of 25 Mycobacterium tuberculosis and nine strains of three other species, was isolated from 400 expectorated sputum specimens submitted on 148 patients from county-wide sources. Eight strains (24% of the total) were isolated from specimens evaluated by Gram stain to be oropharyngeal fluids. The remaining 26 strains were isolated from ungradable specimens a...
متن کاملSputum gram stain assessment in community-acquired bacteremic pneumonia.
A prospective study was performed over a 4.5-year period to determine the ability of a sputum Gram stain to predict the cause of community-acquired bacterial pneumonia. A blood culture isolate, rather than a sputum culture, served as the reference standard to provide precise identification of the etiologic agent. The study population comprised 59 bacteremic adults who expectorated a valid sputu...

15 صفحه اولCulture of specimens other than sputum for Mycobacteria.
A comparison has been made of Lowenstein-Jensen medium, with or without added pyruvate, 7H11 oleic acid-albumin agar slopes made selective by the addition of antibiotics, and selective Kirchner medium in the isolation of tubercle bacilli from specimens other than sputum. A combination of a standard mild preliminary treatment with sulphuric acid and selective medium reduced the contamination rat...
متن کاملQuality of specimens and sputum culture results: a retrospective study.
A retrospective study of laboratory reports of sputums examined in the first 3 months of 1977 and of 1978 showed some interesting findings, which were similar in these 2 years. Analysis of the findings demonstrated that information from a proportion of sputum cultures were not helpful to the clinicians. Probable causes of such unhelpful results and some ways to overcome these problems were disc...
