TWiV 1121: SARS-CoV2 still didn’t come from a lab

AI SummaryIn this episode of This Week in Virology (TWiV), the hosts discuss and refute a recent opinion piece falsely claiming that the COVID-19 pandemic originated in a lab, emphasizing that it began in Nature. They also explore the unique properties of Paride bacteriophage, which can kill dormant, antibiotic-tolerant cells through direct lytic replication. The… Continue reading TWiV 1121: SARS-CoV2 still didn’t come from a lab

Acinetobacter baumannii satellite phage Aci01-2-Phanie depends on a helper myophage for its multiplication

AI SummaryIn this study, researchers investigated the dependence of the satellite phage Aci01-2-Phanie on a helper myophage for its multiplication. They found that the satellite phage is unable to replicate on its own and relies on the helper myophage for successful multiplication. This dependency highlights the complex interactions between phages in bacterial populations and has… Continue reading Acinetobacter baumannii satellite phage Aci01-2-Phanie depends on a helper myophage for its multiplication

Bacteriophage cocktail shows no toxicity and improves the survival of Galleria mellonella infected with Klebsiella spp.

AI SummaryThis study investigates the use of a bacteriophage cocktail to treat infections caused by Klebsiella spp. in Galleria mellonella larvae. The results showed that the bacteriophage cocktail was non-toxic and improved the survival rate of infected larvae. This suggests that bacteriophages could be a promising treatment option for Klebsiella infections.

Structural mechanism of bacteriophage lambda tail’s interaction with the bacterial receptor

AI SummaryThis article discusses the structural mechanism of how the bacteriophage lambda’s tail interacts with the bacterial receptor. The study used high-resolution cryo-electron microscopy to reveal detailed structures of the bacteriophage lambda tail complexed with its LamB receptor and central tail fiber, showing a conformational change upon binding. Understanding this interaction is important for microbiology… Continue reading Structural mechanism of bacteriophage lambda tail’s interaction with the bacterial receptor

New insights into phage therapy design

AI SummaryThis article discusses new findings from a study on phage therapy for treating diseases like cystic fibrosis, offering insights into the design of effective therapies.Results from a new study are providing new insights into the therapeutic potential of bacteriophage (phage) therapy for treating diseases like cystic fibrosis (CF).

Antigen-level resolution of commensal-specific B cell responses can be enabled by phage display screening coupled with B cell tetramers

Adaptive immunity to commensal microbes promotes tissue homeostasis, immunity, and repair, but approaches to identify commensal-specific B cell responses are lacking. Verma et al. utilize phage display screening and subsequent generation of B cell tetramers to identify anatomical compartmentalization of SFB-specific B cell responses in gut-associated lymphoid tissues.
