Animal-free peptones support bacteriophage propagation for therapeutic use without altering bactericidal activity or genomic integrity

Bacteriophage (phage) propagation has traditionally relied on bacterial culture media containing animal-derived ingredients; however, safety concerns with animal-derived materials for production of phages for therapeutic use limit their acceptability. We compared animal-free and traditional media formulations, and evaluated effects on phage yield, bactericidal activity, and genomic characteristics, hypothesizing no significant differences would be observed.

Evaluating the Scale-Up and Sustainability of the Paediatric ESCALATION System in Country Western Australia: A Multi-Methods Study

To identify factors influencing implementation and integration of the paediatric ESCALATION system in country Western Australia.

Corrigendum to: “COVID-19 monitoring with sparse sampling of sewered and non-sewered wastewater in urban and rural communities” [iScience, Volume 26, Issue 7 (2023) 107019]

tesG expression as a potential clinical biomarker for chronic Pseudomonas aeruginosa pulmonary biofilm infections

Pseudomonas aeruginosa infections in the lungs affect millions of children and adults worldwide. To our knowledge, no clinically validated prognostic biomarkers for chronic pulmonary P. aeruginosa infections exist. Therefore, this study aims to identify potential prognostic markers for chronic P. aeruginosa biofilm lung infections.

Real world effectiveness of early ensitrelvir treatment in patients with SARS-CoV-2, a retrospective case series

Ensitrelvir, a 3C-like protease inhibitor, received emergency approval in Japan in November 2022 for treating non-hospitalized patients with mild-to-moderate COVID-19. However, confirmation of its real-world clinical effectiveness is limited.

Profiling epithelial viral receptor expression in amniotic membrane and nasal epithelial cells at birth

Children with wheeze and asthma present with airway epithelial vulnerabilities, such as impaired responses to viral infection. It is postulated that the in utero environment may contribute to the development of airway epithelial vulnerabilities.  

A complete genome of an obligately lytic Pseudomonas aeruginosa bacteriophage, Minga-mokiny 4

We report the isolation of a bacteriophage with obligately lytic activity against Pseudomonas aeruginosa from wastewater. The reported phage, Minga-mokiny 4, appears to belong to the Schitoviridae family, is of the Litunavirus genus, and has a 72,362-bp genome. No known genes associated with lysogeny, bacterial resistance, or virulence were predicted.

Interleukin-4 modulates type I interferon to augment antitumor immunity

Despite advances in immunotherapy, metastatic melanoma remains a considerable therapeutic challenge due to the complexity of the tumor microenvironment. Intratumoral type I interferon (IFN-I) has long been associated with improved clinical outcomes. However, several IFN-I subtypes can also paradoxically promote tumor growth in some contexts. 

Surveillance of avian influenza through bird guano in remote regions of the global south to uncover transmission dynamics

Avian influenza viruses (AIVs) pose a growing global health threat, particularly in low- and middle-income countries (LMICs), where limited surveillance capacity and under-resourced healthcare systems hinder timely detection and response. Migratory birds play a significant role in the transboundary spread of AIVs, yet data from key regions along migratory flyways remain sparse. To address these surveillance gaps, we conducted a study between December 2021 and February 2023 using fresh bird guano collected across 10 countries in the Global South.

Functional characterization of the MED12 p.Arg1138Trp variant in females: implications for neural development and disease mechanism

Seven female individuals with multiple congenital anomalies, developmental delay and/or intellectual disability have been found to have a genetic variant of uncertain significance in the mediator complex subunit 12 gene. The functional consequence of this genetic variant in disease is undetermined, and insight into disease mechanism is required.
