methyl nicotinate/tuberculosis

The proboscis extension reflex in honeybees was evaluated for detection of tuberculosis. Restrained bees were tested with methyl phenylacetate, methyl p-anisate, and methyl nicotinate, previously identified from Mycobacterium tuberculosis cultures, to determine honeybee capacity for signature

Microbial volatile organic compounds (VOCs) have gained prominence in the recent past for their potential use as disease markers. The discovery of microbial VOCs has benefited 'difficult to detect' diseases such as tuberculosis (TB). Few of the identified VOCs of Mycobacterium tuberculosis (Mtb) are

A detection method for nicotinic acid, a specific metabolite marker of Mycobacterium tuberculosis present in cultures and patients' breath, is studied in complex solutions containing other metabolites and in biological media such as urine, saliva and breath condensate. The method is based on the

Mycobacterium tuberculosis releases four volatile compounds, methyl phenyl-acetate, methyl nicotinate, methyl p-anisate and o-phenylanisole, some of which we have previously been reported to be detected in the breath of tuberculosis patients (Syhre et al 2009 Tuberculosis 89 263-6). These volatiles

Trained African giant-pouched rats (Cricetomys gambianus) can detect Mycobacterium tuberculosis and show potential for the diagnosis of tuberculosis (TB). However, rats' ability to discriminate between clinical sputum containing other Mycobacterium spp. and nonmycobacterial species of the

A suite of volatiles have previously been identified as specific markers of Mycobacterium tuberculosis metabolism in vitro. These markers - methyl phenylacetate, methyl p-anisate, methyl nicotinate, o-phenylanisole with the addition of methyl salicylate, may also be derived from other sources and

Recent figures show that tuberculosis (TB) is advancing and killing more than two million people annually, yet no breakthrough in rapid diagnostics is in sight. Volatile metabolites of Mycobacterium tuberculosis (MTB) may provide just that. It is well established that MTB produces nicotinic acid in

A simple, affordable diagnostic test for pulmonary tuberculosis (TB) is urgently needed to improve detection of active Mycobacterium tuberculosis. Recently, it has been suggested that animal behavior can be used as a biosensor to signal the presence of human disease. For example, the giant

Worldwide, tuberculosis (TB) kills nearly 2 million people annually, yet rapid diagnosis still relies on a 100-year-old method of sputum staining for acid-fast bacilli. The advent of solid phase micro-extraction and gas chromatography/mass spectrometry makes it possible to systematically investigate

Pathogenic Mycobacteria cause diseases in animals and humans with significant economic and societal consequences. Current methods for Mycobacterial detection relies upon time- and labor-intensive techniques such as culturing or DNA analysis. Using gas chromatography and mass spectrometry, four
