Mucosal SARS-CoV-2 S1 adenovirus-based vaccine elicits robust systemic and mucosal immunity and protects against disease in animals.

Unlabelled: The COVID-19 pandemic has emphasized the importance and need for accessible safe, effective, and versatile vaccine platforms. While approved SARS-CoV-2 vaccines have been instrumental in saving lives and reducing healthcare and economic burdens, the induction of mucosal immunity remains an unmet need. Here, we engineered and evaluated a non-replicating adenovirus 5 (rAd5)-based vaccine expressing the SARS-CoV-2 S1 subunit (rAd5-SARS2-S1).

Bloodstream infections caused by Staphylococcus aureus in patients admitted to King Abdulaziz University Hospital, Jeddah, Saudi Arabia.

Objective: Currently, there is a limited amount of published data on the incidence of bloodstream infections (BSI) caused by both methicillin-resistant Staphylococcus aureus (MRSA) and methicillin-susceptible Staphylococcus aureus (MSSA) in most parts of the Arabian Peninsula. Thus, it is extremely important to have information concerning the distribution and prevalence of MRSA and MSSA to better handle and manage future epidemics.  This study aimed to investigate the correlation between MRSA and/or MSSA with BSI at King Abdulaziz University Hospital (KAUH), Jeddah, Saudi Arabia.

Novel quinoxaline compound against extended-spectrum beta-lactamases producing bacteria.

Objective: Extended-spectrum beta-lactamases (ESBLs) targeting beta-lactam antibiotics pose a major healthcare challenge. Carbapenems are known to be less impacted. However, the emergence of carbapenem-resistant strains can add further complexity to this existing challenge.

Helminth-derived proteins as immune system regulators: a systematic review of their promise in alleviating colitis.

Helminth-derived proteins have immunomodulatory properties, influencing the host's immune response as an adaptive strategy for helminth survival. Helminth-derived proteins modulate the immune response by inducing anti-inflammatory cytokines, promoting regulatory T-cell development, and ultimately favouring a Th2-biased immune response. This systematic review focused on helminth-derived proteins and explored their impact on reducing inflammatory responses in mouse models of colitis.
