Several studies have compared the diagnostic value of sputum induction (SI) with flexible fiberoptic bronchoscopy (FOB) in diagnosing pulmonary tuberculosis; however, these investigations yield an inconsistent conclusion. This study aims to evaluate the role of acid-fast bacilli (AFB) testing of SI and bronchoalveolar lavage (BAL) samples in suspected pulmonary tuberculosis cases.

Tuberculosis (TB) is caused by Mycobacterium tuberculosis and most commonly occurs in the lung. Only 10-15% of all cases of tuberculosis occur outside the respiratory system. Whereas secondary tuberculosis of the tonsil, where there is sputum-positive pulmonary TB, has been well documented, primary tuberculosis of the tonsil without pulmonary TB is rare, and only a few cases have been reported up to now.

Nontuberculous mycobacterium (NTM) species are ubiquitous microorganisms. NTM pulmonary disease (NTM-PD) is thought to be caused not by human-to-human transmission but by independent environmental acquisition.

Sputum smear conversion is a key indicator of treatment response and reduced infectivity among bacteriologically confrmed pulmonary tuberculosis (PTB) patients. This study aimed at estimating sputum smear conversion and identifying factors hindering sputum smear conversion among bacteriologically confrmed PTB cases in East Gojjam Zone, Northwest Ethiopia.

Xpert MTB/RIF has been shown to have a superior sensitivity to microscopy for acid fast bacilli (AFB) in sputum and has been recommended as a standard first line investigation for pulmonary tuberculosis (PTB). Bronchoscopy is a valuable tool in diagnosing PTB in sputum negative patients.

Vitamin D is involved in the host immune response toward Mycobacterium tuberculosis. However, the efficacy of vitamin D supplementation on sputum conversion, clinical response to treatment, adverse events, and mortality in patients with pulmonary tuberculosis (PTB) remains controversial. We aimed to clarify the efficacy and safety of vitamin D supplementation in PTB treatment.

F-fluorodeoxyglucose positron emission tomography (FDG-PET) is increasingly used to investigate for malignancy in the evaluation of pulmonary nodules, yet both active tuberculosis (TB) and malignancy have high uptake of FDG. Definitive diagnosis of TB can be further hindered in patients without growth of the organism from sputum.

Early diagnosis and treatment of nontuberculous mycobacterial lung diseases (NTM-LD) and pulmonary tuberculosis (PTB) are important clinical issues. The present study aimed to compare and identify the chest CT characteristics that help to distinguish NTM lung disease from PTB in patients with acid-fast bacilli (AFB) smear-positive sputum.

Fiberoptic bronchoscopy (FOB) is a useful diagnosis tool in low-burden countries for patients with suspected pulmonary tuberculosis (TB) who are smear-negative or sputum-scarce. This study sought to determine the accuracy of the Xpert® MTB/RIF (XP) assay using FOB samples.

During the study period (July to December 2016) a total of 188 samples (sputum and blood from each person) have been tested in the National Reference Laboratory (NRL) at the Institute of Chest and Respiratory Diseases / Baghdad. These cases are considered as suspected pulmonary tuberculosis. This study for these 188 suspected specimens declare that, 103 (54.78%) cases were positive using direct assay (AFB smear microscopy) and 85 (45.21%) were considered to be negative cases by smear microscopy.

Pulmonary tuberculosis is one among the most common disease in developing countries. Candida species infection has always seemed to be associated with secondary infections in Tuberculosis. Candida species have been one of the co-infection challenges facing the patients suffering from pulmonary tuberculosis. Hence this study was undertaken to find out the prevalence of Candida species in cases of pulmonary tuberculosis.

This study covering the period from January 2017 to June 2017 was conducted at Department of Microbiology, SN Medical College, India. A total of 300 patients suspecting of having tuberculosis and consenting for HIV testing were included in the study. The TB diagnosis was performed using sputum microscopy (AFB staining) and all the cases were screened for HIV by using rapid HIV kits according to NACO guidelines. Overall, 29 (9.66%) cases were diagnosed as sputum positive pulmonary tuberculosis among which 2 cases (6.90 %) were sero-positive for HIV antibodies.

Bacteriological confirmation plays a key role in the diagnosis of tuberculosis. Many systems have been developed in the recent years apart from traditional microscopy and culture on Lowenstein Jensen (LJ) medium. The objective of this study is to compare the rate of detection of Mycobacteria by acid fast staining, LJ medium and Mycobacteria Growth Indicator Tube (MGIT). Hundred patients with clinical suspicion of pulmonary tuberculosis attending a tertiary care hospital over a period of one and a half years were enrolled in the study.

Pulmonary system is the most commonly involved system in people living with HIV as lungs are continuously exposed to the infection as they are rich in macrophages, dendritic cells, lymphocytes etc. In PLHIV immunity is suppressed, hence lungs are prone for infection and non infectious pulmonary diseases. According to autopsy findings, in HIV lung was affected almost upto 100% in the period of epidemic to 70% in the HAART era. Pneumonia is most common pulmonary manifestation followed by pulmonary tuberculosis and PCP.

Tuberculosis (TB) and HIV have been closely linked since the emergence of AIDS. Worldwide, TB is the most common opportunistic infection affecting HIV-seropositive individuals and it remains the most common cause of death in patients with AIDS. Aim is to determine the percentage of tuberculosis infection in HIV seropositive patients and to assess the type of pulmonary or extra pulmonary tuberculosis infection in Human immuno deficiency virus (HIV) seropositive patients in Udaipur zone. This study will be conducted in the Department of Microbiology, R.N.T.

The purpose of the International Standards for Tuberculosis Care (ISTC) is to describe a widely accepted level of care that all practitioners, public and private, should seek to achieve in managing patients who have, or are suspected of having, tuberculosis. The Standards are intended to facilitate the effective engagement of all care providers in delivering high-quality care for patients of all ages, including those with sputum smear-positive, sputum smear-negative, and extra pulmonary tuberculosis, tuberculosis caused by drug-resistant Mycobacterium tuberculosis complex (M.

Patients who habitually drank alcohol were considered alcoholics, and patients who habitually smoked and were currently smoking were considered smokers for the purpose of the analysis. In the RNTCP, a new smear-positive TB patient is expected to complete treatment within 7 months (6 months 1 month grace period). For patients whose sputum does not convert at 2 months, the intensive phase is extended by one more month and the duration of treatment extended to 8 months (7 months 1 month grace period).

Introduction: Early identification of Tuberculosis (TB) treatment failure using cost effective means is urgently needed in developing nations. The study set out to describe affordable predictors of TB treatment failure in an African setting. Objective: To determine the predictors of treatment failure among patients with sputum smear positive pulmonary TB at Mulago hospital. The study was carried out in the TB clinic of Mulago hospital Kampala, Uganda.
