BACKGROUND Studies examining the transmission of multidrug-resistant tuberculosis (MDR-TB) strains have yielded conflicting results. METHODS We examined transmission of MDR-TB strains using contact tracing data from a low incidence setting. Contacts of MDR-TB cases diagnosed in British Columbia, Canada, from 1990-2008 were identified through a provincial tuberculosis (TB) registry. Tuberculin...
BACKGROUND Multidrug-resistant tuberculosis (MDR-TB) is resistant to both rifampicin (RIF) and isoniazid (INH). Whereas many TB diagnostics detect RIF-resistance, few detect INH-monoresistance, which is common and may increase risk of acquired MDR-TB. Whether inclusion of INH-resistance in a first-line rapid test for TB would have an important impact on MDR-TB rates remains uncertain. METHODS...
Tuberculosis (TB) is a leading cause of mortality and morbidity in the world and this infection is a major public health challenge. TB control is largely dependent on the early diagnosis and managements of suspected cases. Today, for laboratory diagnosis of TB infection, several bacteriological and immunological methods such as sputum smear microscopy, sputum culture and tuberculin skin test ar...
In January 2005, tuberculosis (TB), including multidrug-resistant TB (MDR TB), was reported among Hmong refugees who were living in or had recently immigrated to the United States from a camp in Thailand. We investigated TB and drug resistance, enhanced TB screenings, and expanded treatment capacity in the camp. In February 2005, 272 patients with TB (24 MDR TB) remained in the camp. Among 17 M...
a modified pulsed-field gel electrophoresis (pfge) protocol was developed and applied to clinical isolates of mycobacterium tuberculosis complex to reduce the cost of using lyticase. this protocol reduces the expense of pfge typing of mycobacterium tuberculosis complex as it removes the use of lyticase during the spheroplast formation from these bacteria.
Background: India is a high burden country for Tuberculosis (TB). As per the World Health Organization (WHO) statistics, 24000 cases of Multi Drug Resistant (MDR) TB were diagnosed in India in 2014. MDR-TB patients consist of a heterogeneous cohort and management has its challenges. Aims and objectives: We studied the prevalence of PreExtensively Drug Resistant TB (Pre XDR-TB) and Extensively D...
BACKGROUND The World Health Organization (WHO) tuberculosis (TB) symptom screening instrument (WHO-TB) can identify human immunodeficiency virus (HIV)-infected individuals at low risk of tuberculosis (TB); however, many patients report WHO-TB symptoms and require further TB investigations. We hypothesized that further clinical scoring could classify subjects with a positive WHO-TB screening res...
BACKGROUND A high burden of tuberculosis (TB) occurs in sub-Saharan African countries and many cases of active TB and drug-resistant TB remain undiagnosed. Tertiary care hospitals provide an opportunity to study TB co-morbidity with non-communicable and other communicable diseases (NCDs/CDs). We evaluated the burden of undiagnosed pulmonary TB and multi-drug resistant TB in adult inpatients, re...
Background Public and private health sectors both play a crucial role in the health systems of low- and middleincome countries (LMICs). The tuberculosis (TB) control strategy in India encourages the public sector to actively partner with private practitioners (PPs) to improve the quality of front line service delivery. However, ensuring effective and sustainable involvement of PPs constitutes a...
