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.

Bacterial vaginosis is caused by an imbalance of the organisms that naturally exist in the vagina. The importance of bacterial vaginosis with respect to pregnant women’s health is emphasized by the association between bacterial vaginosis and adverse outcome of pregnancy. The aim of present study was to evaluate the direct smear microscopy and culture for determination of bacteria from vaginal discharge of pregnant women. Vaginal discharge in women is sometimes caused by candida and aerobic bacteria organisms like E.coli, staphylococcus aureus, and β- haemolytic streptococcus.

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.

Soil transmitted helminths or geohelminths still contribute a major burden to many countries including India. It’s of utmost importance to detect them accurately and timely. Studies on this group of intestinal parasites in adults are rare. Hence, the study explored the usefulness of stool concentration technique and compared them with the direct microscopy for better isolation of the geohelminths in adults. In this study, 254 consecutive stool samples were taken from adult patients of the hospital.

TB is the most common opportunistic infection (OI) among HIV infected individuals, and co infected individuals are at high risk of death. TB is the largest single cause of death in the setting of AIDS, accounting for 26% of AIDS related deaths, 99% of which occur in developing countries. HIV Associated Tuberculosis remains a major global public health challenge. Hence routine TB screening among PLWHA (People Living with HIV-AIDS) offers the opportunity to identify those without TB, helps for early diagnosis and promptly treat TB. The aims of the study are 1.

The Bangalore district tuberculosis programme (the programme assessed). The Bangalore District has an area of 7798 square kilometers and had a population of about 1.3 million according to the census of 1961 (excluding the metropolitan area). The District has 13 towns and 2477 villages. The DTP was implemented in 1963, not by the staff of the DTC (as happens in other districts) but by trainees of two courses held in 1963 at the National Tuberculosis Institute (NTI) Bangalore. In all, 15 microscopy centres were organised in general health institutions of the District.

About a third of the world’s population is infected with Mycobacterium tuberculosis. Tuberculosis remains one of the biggest killers among infectious diseases, with up to three million people dying from tuberculosis each year (Dye 1999). Diagnosis of tuberculosis generally relies on smear microscopy and culture of the sputum. The disease typically results in progressively destructive lung lesions but may affect almost any part of the body, usually with advanced wasting and death inmore than half of cases in the absence of intervention.

Volatile organic compounds (VOCs) in breath may contain biomarkers of active pulmonary tuberculosis derived from the infectious organism (metabolites of Mycobacterium tuberculosis) and from the infected host (products of oxidative stress). Methods: We analyzed breath VOCs in 226 symptomatic high-risk patients in USA, Philippines, and UK, using gas chromatography/mass spectroscopy. Diagnosis of disease was based on sputum culture, smear microscopy, chest radiography and clinical suspicion of tuberculosis (CSTB). Chromatograms were converted to a series of 8 s overlapping time slices.
