Mashup Score: 1
Annually, an estimated 11 million people require medical treatment for burn wounds globally. Mortality rates of burn wounds requiring treatment are high and can even reach up to 25%, depending on many factors, including age, socioeconomic factors, and the size of the wound (1). It is estimated that bacterial infections account for 75% of this mortality (2, 3). Burn wounds are especially prone to infection due to the disruption of the skin barrier, leading to impaired host defenses. Consequently, wound healing is delayed, and hospital stays are prolonged (4). Staphylococcus aureus (S. aureus) is one of the major causative agents of burn wound infections. To treat burn wound infections, wound debridement is typically performed to remove the affected tissue, and topical antimicrobial therapy is initiated, usually together with systemic antibiotic administration (5). For topical treatment, antimicrobial ointments (e.g., silver sulfadiazine) or antibiotics are often used, with mupirocin and

Mashup Score: 1Diversifying T-cell responses: safeguarding against pandemic influenza with mosaic nucleoprotein | Journal of Virology - 5 day(s) ago
The World Health Organization (WHO) estimates that seasonal influenza causes 3–5 million cases of severe illness annually. The influenza virus frequently undergoes genetic changes through antigenic drift and antigenic shift, resulting in annual epidemics …

Mashup Score: 0Chlamydia trachomatis impairs T cell priming by inducing dendritic cell death | Infection and Immunity - 14 day(s) ago
Chlamydia trachomatis is an obligate intracellular bacterium that infects epithelial cells. It is the most common bacterial sexually transmitted disease in the United States, with an estimated 2.86 million infections occurring annually (1). While curable with antibiotics, infections are often asymptomatic and thus left untreated (2). This can lead to serious sequelae in women, such as pelvic inflammatory disease, infertility, and ectopic pregnancy (3). Despite the high public health burden of C. trachomatis, a vaccine to prevent this disease is not available. A better understanding of the immune response to C. trachomatis is, therefore, crucial to the development of an effective vaccine (4).

Mashup Score: 1Polycytotoxic T cells mediate antimicrobial activity against intracellular Mycobacterium tuberculosis | Infection and Immunity - 2 month(s) ago
To establish active infection, inhaled Mycobacterium tuberculosis (Mtb) must overcome the physical barriers of the upper respiratory tract and invade alveolar macrophages. Clearance of the pathogen from the lower airways requires a fine-tuned interaction of immune cells, most prominently T-lymphocytes and macrophages. There is definite evidence for the critical role of CD4+ T-lymphocytes in activating the antimicrobial activity of macrophages (1). The evidence for a contribution of CD8+ T cells in protection against Mtb is steadily increasing through conclusive animal studies and strong circumstantial evidence from human ex vivo and in vitro experiments (2–7). CD8+ T-lymphocytes promote the control of Mtb infection indirectly by the release of macrophage-activating cytokines or directly by the injection of cytotoxic molecules into infected macrophages (8). The granular molecules perforin, granzyme B, and granulysin interact to define an antimicrobial effector pathway leading to direct

Mashup Score: 30
Non-diphtheriae Corynebacterium species are Gram-positive catalase-positive rod-shaped bacteria that are ubiquitous in the environment and are commensal organisms of human mucosal surfaces (1). However, non-diphtheriae Corynebacterium species have emerged as clinically significant opportunistic pathogens, particularly in immunocompromised individuals and those with indwelling medical devices, causing a wide spectrum of clinical infections (1–5). Furthermore, management of infection is often complicated by the resistance of non-diphtheriae Corynebacterium species to multiple classes of antibiotics, impairing the selection of effective empiric and definitive therapy (6). In this context, with the increasing recognition of the clinical significance of these microorganisms, a comprehensive understanding of their antimicrobial susceptibility profiles to guide effective therapeutic strategies is needed and, in comparison to more routine culprit pathogens, data on species-specific susceptibil
