The disease duration of TB in freshmen was short, leading to asymptomatic or mild symptoms and possibly negative sputum test results. Additionally, the quality of sputum samples was poor and subjects may not have been aware of the importance of sputum examination and failed to retain the ...
1e). These results suggest that the Mtb PtpA-interacting TRIM27 may play an important regulatory role during mycobacterial infection dependent on its E3 ubiquitin ligase activity, which could be potentially counteracted by the Mtb effector protein PtpA....
Free energy landscape (FEL) is plotted using the results of PCA. It is for the analysis of the metastable conformations of the isocitrate lyase in the three systems, and it is verified by the kernel density estimation (KDE) plots (Fig.10). In the apoenzyme system, two energy minima can ...

Is a chronic, progressive, and potentially disfiguring form of cutaneous tuberculosis, which occurs in patients with a high degree of immunity againstMycobacterium tuberculosis. Tuberculin skin test: (PPD, Mantoux technique, TB skin test) technique consists in one injection of purified protein derivative...
tuberculosis results in the establishment of infection are not completely understood and have mainly been inferred from studies measuring conversion of contacts to pulmonary TB patients assessed by the tuberculin skin test. Estimates suggest that infection occurs in only 20–50% of subjects who inhale ...
Diagnosis of tuberculosis is made by a positive tuberculin skin test, an immune reaction to a small quantity of tuberculosis antigens. It can be confirmed by X rays of the chest and microscopic examination of sputum. Detection of significant numbers of acid-fast bacilli (using the Ziehl-Ne...

The impact of tuberculosis (TB) is exacerbated in Africa because of the human immunodeficiency virus (HIV) pandemic. Pulmonary tuberculosis (PTB) diagnosis is difficult in HIV-infected patients and negative sputum results are more common which leads to diagnostic delay and increases morbidity and mort...
Results ESX motifs are required for CpnT stability and/or TNT secretion by M. tuberculosis CpnT does not contain a canonical Sec signal peptide in contrast to any other known outer membrane proteins (Supplementary Fig. 1). Since CpnT contains three YXXXE motifs, which were previously shown...
