Nontuberculous mycobacteria (NTM) are categorized as one of the large and diverse groups of environmental organisms which are abundant in water and soil.  NTM cause a variety of diseases in humans that mainly affect the lung. A predisposition to pulmonary NTM is evident in patients with parenchymal structural diseases including bronchiectasis, emphysema, tuberculosis (TB), cystic fibrosis (CF), rheumatologic lung diseases and other chronic diseases with pulmonary manifestations. Lung infections are not the only consequences of being infected by NTM as they can also infect skin and soft tissue and may also cause lymphadenitis (predominantly in young children) and disseminated disease in human immunodeficiency virus (HIV)-infected patients or those with severely compromised immune system...

Although the infectious diseases tuberculosis (TB) and cryptococcosis both cause formation of single or multiple nodules in immunodeficient hosts, cases of co-infection of these diseases are rarely seen. We report a patient who was co-infected with TB and cryptococcosis. A male patient with no clinical evidence of immunodeficiency presented with a 3-week history of abdominal distension accompanied by oedema of recurring lower extremities. The patient was diagnosed with tuberculous peritonitis and tuberculous pleurisy by an abdominal puncture biopsy...

A 44-year-old woman was referred to our hospital with pleural effusion and unknown fever. Mycobacterium tuberculosis was not detected by culture of pleural effusion and sputum and gastric fluid. Pleural fluid was serous and exudative, and cytological examination showed no malignant cells. Computed tomography revealed a little pleural thickening of the right middle lobe and massive pleural effusion. As acute pleurisy was suspected based on the findings of imaging studies, thoracoscopy was performed under general anesthesia...

We present a patient diagnosed with skin sarcoidosis, breast cancer, pulmonary tuberculosis, and peritoneal sarcoidosis with a past history of colorectal cancer. During stage work up for breast cancer, suspicious lesions on peritoneum were observed in imaging studies. Considering our patient's history and imaging findings, we initially suspected peritoneal carcinomatosis. However, the peritoneal lesion was diagnosed as sarcoidosis in laparoscopic biopsy. This case demonstrates that abdominal sarcoidosis might be considered as a differential diagnosis when there is a lesion suspected of being peritoneal carcinomatosis with nontypical clinical presentations...

The pathogenesis of Mycobacterium tuberculosis (Mtb) is intrinsically linked to its intimate and enduring interaction with its host, and understanding Mtb-host interactions at a molecular level is critical to attempts to decrease the significant burden of tuberculosis disease. The marked heterogeneity that exists in lesion progression and outcome during Mtb infection necessitates the development of methods that enable in situ analyses of Mtb biology and host response within the spatial context of tissue structure...

BACKGROUND: Tuberculosis (TB) control programs face the challenges of decreasing incidence, mortality rates, and drug resistance while increasing treatment adherence. The Brazilian TB control program recommended the decentralization of patient care as a strategy for combating the disease. This study evaluated the performance of this policy in an area with high default rates, comparing epidemiological and operational indicators between two similar municipalities. METHODS: This study analyzed epidemiological and operational indicators on new cases of pulmonary tuberculosis reported in the Brazilian Notifiable Diseases Information System between 2006 and 2015...

The pathogenic potential of Mycobacterium tuberculosis largely depends on ESX secretion systems exporting members of the multigenic Esx, Esp, and PE/PPE protein families. To study the secretion and regulation patterns of these proteins while circumventing immune cross-reactions due to their extensive sequence homologies, we developed an approach that relies on the recognition of their MHC class II epitopes by highly discriminative T cell receptors (TCRs) of a panel of T cell hybridomas. The latter were engineered so that each expresses a unique fluorescent reporter linked to specific antigen recognition...

Pulmonary tuberculosis (TB) is nowadays one of the most common causes of infectious disease-related morbility and mortality worldwide. The differential diagnosis between TB and some others conditions is an emerging problem, particularly challenging when TB imaging mimicks sarcoidosis, lymphoproliferative disorders and pulmonary neoplasms. In these cases, the correct diagnoses can be made with certainty only with trans-bronchial or CT guided biopsy.

MALDI mass spectrometry imaging (MALDI-MSI) is a technique capable of label-free identification and visualization of analytes in tissue sections. We have previously applied MALDI-MSI to study the spatial distribution of tuberculosis (TB) drugs in necrotic lung granulomas characteristic of pulmonary TB disease, revealing heterogeneous and often suboptimal drug distribution. To investigate the impact of differential drug distribution at the sites of infection, we sought to image mycobacterial biomarkers to co-register drugs and bacteria in lesion sections...
