BACKGROUND Tuberculosis (TB) is an increasing public health concern worldwide. On a global scale it has a devastating impact in developing nations. Genital TB, an extrapulmonary form, is not uncommon particularly in areas where pulmonary TB is prevalent. Genital TB may be asymptomatic or may even masquerade as other gynaecological conditions; hence, diagnosis requires a high degree of suspicion...
BACKGROUND The occurrence of nasopharyngeal tuberculosis is rare even in areas where tuberculosis is endemic. Here, we report a case of rare primary nasopharyngeal tuberculosis, promptly evaluated by nasolaryngoscopy. CASE PRESENTATION A 78-year-old woman presented with postnasal drip and a cough of 1-month duration. Endoscopic examination of the nasopharynx revealed irregular mucosal thicken...
bcg (bacille calmette–guérin) vaccine is administered worldwide to prevent severe forms of tuberculosis. it is considered to be safe; however, occasional complications are seen. the most serious complication is bcgosis. we report a case of bcgosis with granulomatous hepatitis and acid-fast bacilli in liver and spleen. we treated the patient with antituberculosis drugs without any response to tr...
Introduction: Leprosy is an ancient deforming disease caused by Mycobacterium leprae, which is still poorly understood and often feared by the general public and even by some in the health care professions. Fortunately, the outlook for patients has dramatically improved over the last three decades with the introduction of multi-drug treatment and management strategies that have somewhat dim...
Mycobacterium tuberculosis bacilli display two signature features: acid-fast staining and the capacity to induce long-term latent infections in humans. However, the mechanisms governing these two important processes remain largely unknown. Ser/Thr phosphorylation has recently emerged as an important regulatory mechanism allowing mycobacteria to adapt their cell wall structure/composition in res...
The cellular reactions to defatted tubercle bacilli are complex and like those to heat-killed whole tubercle bacilli. The firmly bound lipid, when removed from these organisms, is non-acid-fast; it contains an hydroxy acid which is acid-fast and a polysaccharide, which is not. This hydroxy acid gives rise to foreign body giant cells and the tissues eventually become infiltrated with eosinophile...
BACKGROUND Implementation of Multi drug Therapy (MDT) regimen has resulted in the decline of the total number of leprosy cases in the world. Though the prevalence rate has been declining, the incidence rate remains more or less constant and high in South East Asian countries particularly in India, Nepal, Bangladesh, Pakistan and Srilanka. Leprosy, particularly that of multibacillary type spread...
When leprosy bacilli from human patients are inoculated into the foot-pads of CFW mice, a microscopic granuloma containing acid-fast bacilli develops in a characteristic manner. This has been seen in 22 of 22 instances with leprosy bacilli from nasal washings, in 12 of 16 instances with leprosy bacilli from skin biopsies, and in none of 16 cases where the nasal washings were not observed to con...
RATIONALE TBDx automated microscopy is a novel technology that processes digital microscopic images to identify acid-fast bacilli (AFB). Use of TBDx as part of a diagnostic algorithm could improve the diagnosis of tuberculosis (TB), but its performance characteristics have not yet been formally tested. OBJECTIVES To evaluate the performance of the TBDx automated microscopy system in algorithm...
