Evaluation of microbiological variants of sputum processing and concentration of mycobacteria to optimize the microscopic and imaging diagnosis of tuberculosis
(Medknow Publications, 2019)
Background: Direct sputum smear is still the first-choice tool for screening of tuberculosis worldwide. Variants of this technique, to improve the sensitivity are desired. Methods: Two microbiological variants of the ...
Performance of Bleach Method Sputum Smear Microscopy for the Diagnosis of Tuberculosis in a Highly Endemic District in Lima, Peru
(MDPICH, 2022-12-22)
Background: Sputum smear microscopy (SSM) is a screening test used to diagnose tuberculosis (TB); however, its performance and sensitivity are relatively low, which can lead to false negatives. We designed a cross-sectional ...

Induced sputum is safe and well-tolerated for TB diagnosis in a resource-poor primary healthcare setting
(American Society of Tropical Medicine and Hygiene, 2015)
Improved tuberculosis (TB) diagnostics are required. Induced sputum sampling is superior to spontaneous sputum analysis for diagnosis of pulmonary TB. Therefore, we examined the applicability of induced sputum in primary ...
A novel algorithm for detection of tuberculosis bacilli in sputum smear fluorescence images
(Institute of Advanced Engineering and Science, 2020)
This work proposes an algorithm aimed at recognizing and accounting Koch bacilli in digital images of microbiological sputum samples stained with auramine, in order to determine the degree of concentration and the state ...
An electrochemical biosensor for the detection of Mycobacterium tuberculosis DNA from sputum and urine samples
(Public Library of Science, 2020)
Tuberculosis (TB) is a major global public health problem with high mortality and morbidity. In low-middle income countries (LMIC) a large number of respiratory symptomatic cases that require TB screening per year demands ...
Evaluation of bleach-sedimentation for sterilising and concentrating Mycobacterium tuberculosis in sputum specimens
(BioMed Central, 2011)
Background: Bleach-sedimentation may improve microscopy for diagnosing tuberculosis by sterilising sputum and concentrating Mycobacterium tuberculosis. We studied gravity bleach-sedimentation effects on safety, sensitivity, ...
Sputum cytology in the diagnosis of pulmonary paracoccidioidomycosis
(1991-06-01)
The presence of Paracoccidioides brasiliensis was determined in sputum samples from 50 patients with paracoccidioidomycosis using four different techniques: (a) cell-block preparations stained with silver methenamine, (b) ...
