Today Miliary Tuberculosis in Central Europe is a rare disease, quite often with resulting diagnostic uncertainty. The terms "miliary" and "tubercle" are outlined with their up to now accepted historical roots. An analysis of Marcello Malpighi's quite unknown post-mortem reports by the Italian author L. Munster reveals an earlier use of both terms than described till now.

Chronic infections affect a third of the world's population and can cause bone marrow suppression, a severe condition that increases mortality from infection. To uncover the basis for infection-associated bone marrow suppression, we conducted repeated infection of WT mice with Mycobacterium avium. After 4-6 months, mice became pancytopenic. Their hematopoietic stem and progenitor cells (HSPCs) were severely depleted and displayed interferon gamma (IFN-γ) signaling-dependent defects in self-renewal. There was no evidence of increased HSPC mobilization or apoptosis...

The protective effects of the tuberculosis vaccine Bacillus Calmette-Guerin (BCG) on unrelated infections are thought to be mediated by long-term metabolic changes and chromatin remodeling through histone modifications in innate immune cells such as monocytes, a process termed trained immunity. Here, we show that BCG induction of trained immunity in monocytes is accompanied by a strong increase in glycolysis and, to a lesser extent, glutamine metabolism, both in an in-vitro model and after vaccination of mice and humans...

Non-tuberculous mycobacteria (NTM) are ubiquitous in the environment and an increasing number of NTM species have been isolated and characterized from both humans and animals, highlighting the zoonotic potential of these bacteria. Host exposure to NTM may impact on cross-reactive immune responsiveness which may affect diagnosis of bovine tuberculosis and may also play a role in the variability of the efficacy of Mycobacterium bovis BCG vaccination against tuberculosis. In this study we characterized 10 NTM isolates originating from water, soil, nasal swabs of cattle and African buffalo as well as bovine tissue samples...

Ethnicity, geography, and socioeconomic factors are among the aspects influencing the prevalence of uveitis in specific areas and countries. Human T-lymphotropic virus type 1-associated uveitis and ocular toxoplasmosis are endemic to Southern Kyushu, the southern-most region of Japan. Recent reports have postulated that the prevalence of intraocular tuberculosis is increasing in Tokyo. This review focuses on local factors that affect the three major vectors for infectious endemic uveitis in Japan, as well as their routes of transmission and factors for improving diagnoses...

To determine why cultivation of Mycobacterium leprae in vitro has not been successful, we attempted to culture this bacterium in media supplemented with a variety of biological materials. We observed a slight increase in the number of cells in medium supplemented with human blood plasma and an extract of nude mouse tissue after more than 3 months of cultivation at 30°C. To ascertain whether this increase was real growth, we analyzed the growth by droplet digital PCR. The analysis had the following two results: the slow increase in the copy number of cell-associated DNA and the release of a large amount of DNA into the culture medium from bacterial cells during cultivation...

Mycobacterium tuberculosis produces dideoxymycobactin-838 (DDM-838), a lipopeptide that potently activates T cells upon binding to the MHC-like antigen-presenting molecule CD1a. M. tuberculosis produces DDM-838 in only trace amounts and a previous solid-phase synthesis provided sub-milligram quantities. We describe a high yielding solution-phase synthesis of DDM-838 that features a Mitsunobu substitution that avoids yield-limiting epimerization at lysine during esterification, and amidation conditions that prevent double-bond isomerization of the Z-C20:1 acyl chain, and provides material with equivalent antigenicity to natural DDM-838...

Objective: to analyze the meanings produced by nursing professionals in the directly observed treatment (DOT) for tuberculosis (TB) in the city of São Paulo. Method: this is a qualitative study, conducted in March and April 2014 through semi-directed interviews with nine nurses. The empirical material produced was analyzed according to the theoretical and methodological support of the Discourse Analysis of French matrix. Results: results have emerged as three discursive blocks: conditions for the production of tuberculosis control practices; production conditions facilitating the treatment of tuberculosis; and production conditions hindering the treatment of tuberculosis...

The ability to detect tuberculosis (TB) continues to be a global health care priority. This paper describes the development and preliminary assessment of the clinical accuracy of a heterogeneous immunoassay that integrates a serum pretreatment process with readout by surface-enhanced Raman scattering (SERS) for the low-level detection of mannose-capped lipoarabinomannan (ManLAM). ManLAM is a major virulence factor in the infectious pathology of Mycobacterium tuberculosis (Mtb) that has been found in the serum and other body fluids of infected patients...

The role of the PD-1/PD-L pathway in a murine model of tuberculosis remains controversial regarding viral infections and clinical tuberculosis. We conducted a case-control study to investigate the modulating role and mechanism of the PD-1/PD-L pathway in patients with active tuberculosis. Fifty-nine participants, including 43 active tuberculosis (ATB) patients and 16 healthy controls (HC), were enrolled. Cell surface staining and flow cytometry were used to detect the expressions of PD-1 and its ligands on T cells and monocytes...

Natural killer (NK) cells are traditionally considered as innate cells, but recent studies suggest that NK cells can distinguish antigens, and that memory NK cells expand and protect against viral pathogens. Limited information is available about the mechanisms involved in memory-like NK cell expansion, and their role in bacterial infections and vaccine-induced protective immune responses. In the current study, using a mouse model of tuberculosis (TB) infection, we found that interferon-gamma producing CD3-NKp46+CD27+KLRG1+ memory-like NK cells develop during Bacille Calmette-Guérin vaccination, expand, and provide protection against challenge with Mycobacterium tuberculosis (M...

Five anti-tumor necrosis factor (anti-TNF) agents have received regulatory approval for use in rheumatology: adalimumab, golimumab, infliximab, certolizumab, and etanercept. Apart from their well-documented therapeutic value, it is still uncertain to what extent they are associated with an increased risk of infectious adverse events. Areas covered: We conducted a systematic review and meta-analysis of published randomized studies to determine the effect of anti-TNF drugs on the occurrence of infectious adverse events (serious infections; tuberculosis; opportunistic infections; any infection)...

Benign cicatricial airway stenosis (BCAS) is a potentially life-threatening disease. Recurrence occurs frequently after endoscopic treatment. Paclitaxel is known to prevent restenosis, but its clinical efficacy and safety is undetermined. Therefore, in this study, we investigated the efficacy and associated complications of paclitaxel as adjuvant treatment for BCAS of different etiologies. The study cohort included 28 patients with BCAS resulting from tuberculosis, intubation, tracheotomy, and other etiologies...

: Extracellular DNA (eDNA) is an integral biofilm matrix component of numerous pathogens, including nontuberculous mycobacteria (NTM). Cell lysis is the source of eDNA in certain bacteria, but the source of eDNA remains unidentified for NTM, as well as for other eDNA-containing bacterial species. In this study, conditions affecting eDNA export were examined, and genes involved with the eDNA export mechanism were identified. After a method for monitoring eDNA in real time in undisturbed biofilms was established, different conditions affecting eDNA were investigated...
