Fluorescence Microscopy For Mycobacterium Tuberculosis

However its use in resource limited settings has been limited by the high cost of the excitatory light source. Hanscheid and colleagues also draw attention to some of the advantages of fluorescence microscopy in particular the quicker turnaround times for smear results compared with light microscopy using ziehl neelsen staining a finding substantiated in our review. A method of fluorescent nanoparticle based indirect immunofluorescence microscopy fnp iifm was developed for the rapid detection of mycobacterium tuberculosis.

Fluorescence microscopy for mycobacterium tuberculosis. Fluorescence microscopy offers well described benefits compared with conventional light microscopy for the evaluation of sputum smear samples for tuberculosis. In 2009 the evidence for the efficacy of led microscopy was assessed by the world health organization on the basis of standards appropriate for evaluating both the accuracy and the effect of new tb diagnostics on patients and public health. Comment on lancet infect dis. We evaluated the diagnostic performance of fluorescence microscopy using novel light emitting diode led technology as an alternative to the conventional mercury vapor lamp mvp.

While earlier studies indicated greater sensitivity with fluorescent microscopy this was not found in the two studies using light microscopy as compared with the six studies using fluorescence microscopy table table2 2 1 2 5 9 10 15 21 27. Background the sensitivity of smear microscopy for diagnosis of tuberculosis might be improved through treatment of sputum with sodium hypochlorite and application of fluorescent microscopy. Fluorescence versus conventional sputum smear microscopy for tuberculosis.

Most of the worlds tuberculosis cases occur in low income and middle income countries where sputum microscopy with a conventional light microscope is the primary method for diagnosing pulmonary tuberculosis. Studies conducted in reference laboratory settings showed led fms to have an average of 10 greater sensitivity than light microscopy and similar specificity 131415.
