Molecular characterisation of Streptococcus pyogenes (StrepA) non-invasive isolates during the 2022-23 UK upsurge

This study characterizes non-invasive Streptococcus pyogenes isolates from a 2022-23 UK scarlet fever upsurge, revealing strain diversity and genomic features associated with different infection types.

Broad and strong memory CD4+ and CD8+ T cells induced by SARS-CoV-2 in UK convalescent COVID-19 patients.

This study examines T cell immunity in UK COVID-19 patients, finding stronger and broader memory T cell responses in severe cases, with implications for vaccine design.

Spike mutation pipeline reveals the emergence of a more transmissible form of SARS-CoV-2

The paper develops a pipeline to track SARS-CoV-2 mutations in the Spike protein, identifying D614G as a rapidly spreading mutation with potential implications for transmission and immune evasion.

The Consequences of Egg Adaptation in the H3N2 Component to the Immunogenicity of Live Attenuated Influenza Vaccine

This study examines how egg adaptation of the H3N2 influenza vaccine strain affects antibody responses in children, finding higher seroconversion rates to the adapted strain but differential mucosal IgA responses based on prior serostatus.

Genomic and epidemiological evidence of a dominant Panton-Valentine leucocidin-positive Methicillin Resistant Staphylococcus aureus lineage in Sri Lanka with spread to the United Kingdom and Australia

The paper conducts genomic analysis of MRSA in Sri Lanka, identifying a dominant PVL-positive ST5-MRSA-IVc lineage that spreads internationally.

LOW-BIAS RNA SEQUENCING OF THE HIV-2 GENOME FROM BLOOD PLASMA

This study uses RNA-Seq without PCR amplification to sequence the HIV-2 genome from plasma samples, revealing low genetic diversity in the vpx gene.
