AI Article Synopsis
Article Abstract
Nowadays, antibiotic resistance is a serious global health concern, for it is observed every- where on the earth. While antibiotic is effective for controlling pathogens, an inappropriate use of the antibiotic leads to antibiotic resistance. Given that the ability to develop novel anti- biotics is quite limited, a new strategy must be developed to fight against it. Mucosal- associated invariant T cells (MAITs) belong to a family of the innate-like T cells that bridges the gap between the innate and the adaptive immunity. We have generated iPSCs from MAITs and redifferentiated MAITs from the iPSCs. These MAITs exerted anti- mycobacterial activity in mice. Advent of such cells will pave the way to exploit a novel arsen- al against antibiotic resistance.

Salmonella Dublin is a serovar that causes severe infections and cattle. Despite the importance of this agent, research on achieving its elimination from dairy farms is limited, which complicates risk mitigation and control efforts. This study thus aimed to assess the prevalence of S.

The rise of antimicrobial resistance represents a significant global health threat, driven by the diminishing efficacy of existing antibiotics, a lack of novel antibacterials entering the market, and an over- or misuse of existing antibiotics, which accelerates the evolution of resistant bacterial strains. This review focuses on innovative therapies by highlighting 19 novel antibacterials in clinical development as of June 2024. These selected compounds are characterized by new chemical scaffolds, novel molecular targets, and/or unique mechanisms of action, which render their potential to break antimicrobial resistance particularly high.

Despite significant global reductions in cases of pneumonia during the last 3 decades, pneumonia remains the leading cause of post-neonatal mortality in children aged <5 years. Beyond the immediate disease burden it imposes, pneumonia contributes to long-term morbidity, including lung function deficits and bronchiectasis. Viruses are the most common cause of childhood pneumonia, but bacteria also play a crucial role.
