Tuberculosis remains a worldwide health concern, largely due to the emergence of multi-drug-resistant (MDR) and extensive-drug-resistant (XDR) Mycobacterium tuberculosis co-infection with HIV. The exact mechanism of Mycobacterium virulence, pathogenesis, and persistence is not fully understood. The hallmark of tuberculosis, granulomas are promoted by Mycobacterium virulence factors, and they have long been considered a structural advantage to the host. However, this traditional view has been challenged recently, largely due to the evidence originating from the M. marinum-zebrafish model. As a genetically tractable model, zebrafish provide unprecedented opportunities to address the pathogenesis of tuberculosis from a systems biology perspective. The latest data from this model are summarized in this review, special attention is given to the shared pathway and network between zebrafish and humans. This research serves to deepen our understanding of this complex process and to promote the discovery of better countermeasures against tuberculosis.

Background: When Behçet's disease is complicated with gastrointestinal ulcers, it is referred to as intestinal Behçet's disease (BD). Clinically uncommon, this condition can involve the entire gastrointestinal tract, often presenting diagnostic challenges in differentiation from Crohn's disease.
Methods: In this case, atypical BD was diagnosed through endoscopic examination, whereas latent tuberculosis infection (LBTI) was confirmed via T-SPOT and PPD tests.

is a fungal pathogen that can cause lethal disease in immunocompromised patients. Immunocompetent host immune responses, such as formation of pulmonary granulomas, control the infection and prevent disseminated disease. Little is known about the immunological conditions establishing the latent infection granuloma in the lungs.

In this paper, we introduce and analyze a discrete-time model of an epidemic spread in a heterogeneous population. As the heterogeneous population, we define a population in which we have two groups which differ in a risk of getting infected: a low-risk group and a high-risk group. We construct our model without discretization of its continuous-time counterpart, which is not a common approach.

BCG remains the only licensed vaccine for tuberculosis (TB), but its efficacy wanes over time. Subunit vaccines, aim to improve BCG immunity and protection, by inducing responses to a few mycobacterial antigens delivered with a specific platform. Since the platform shapes the immune response induced, selecting the right platform has been challenging due to the lack of immune correlates of protection.

Background: Globally, over one-third of pulmonary tuberculosis (TB) disease diagnoses are made based on clinical criteria after a negative bacteriological test result. There is limited information on the factors that determine clinicians' decisions to initiate TB treatment when initial bacteriological test results are negative.
Methods And Findings: We performed a systematic review and individual patient data meta-analysis using studies conducted between January 2010 and December 2022 (PROSPERO: CRD42022287613).
