XBB.1.5 monovalent mRNA vaccine booster elicits robust neutralizing antibodies against XBB subvariants and JN.1
Cell Host Microbe. 2024 Feb 10:S1931-3128(24)00018-0. doi: 10.1016/j.chom.2024.01.014. Online ahead of print.ABSTRACTCOVID-19 vaccines have recently been updated to specifically encode or contain the spike protein of the SARS-CoV-2 XBB.1.5 subvariant, but their immunogenicity in humans has yet to be fully evaluated and reported, particularly against emergent viruses that are rapidly expanding. We now report that administration of an updated monovalent mRNA vaccine booster (XBB.1.5 MV) to previously uninfected individuals boosted serum virus-neutralizing antibodies significantly against not only XBB.1.5 (27.0-fold increase)...

Donor-recipient intermicrobial interactions impact transfer of subspecies and fecal microbiota transplantation outcome
Cell Host Microbe. 2024 Feb 12:S1931-3128(24)00017-9. doi: 10.1016/j.chom.2024.01.013. Online ahead of print.ABSTRACTStudies on fecal microbiota transplantation (FMT) have reported inconsistent connections between clinical outcomes and donor strain engraftment. Analyses of subspecies-level crosstalk and its influences on lineage transfer in metagenomic FMT datasets have proved challenging, as single-nucleotide polymorphisms (SNPs) are generally not linked and are often absent. Here, we utilized species genome bin (SGB), which employs co-abundance binning, to investigate subspecies-level microbiome dynamics in patients with...

Designing microbial communities to starve out invading pathogens

Breakthrough infections are common, even in highly vaccinated populations, making it vital to understand immune cross-protective repertoires to variants. Two studies in this issue show that the primed T cell repertoire comprises strong cross-recognition of current variants.PMID:38359794 | DOI:10.1016/j.chom.2024.01.010 (Source: Cell Host and Microbe)

Susceptible bacteria "can" survive antibiotic treatment in the mammalian gastrointestinal tract without evolving resistance
Cell Host Microbe. 2024 Feb 6:S1931-3128(24)00016-7. doi: 10.1016/j.chom.2024.01.012. Online ahead of print.ABSTRACTAntibiotic resistance and evasion are incompletely understood and complicated by the fact that murine interval dosing models do not fully recapitulate antibiotic pharmacokinetics in humans. To better understand how gastrointestinal bacteria respond to antibiotics, we colonized germ-free mice with a pan-susceptible genetically barcoded Escherichia coli clinical isolate and administered the antibiotic cefepime via programmable subcutaneous pumps, allowing closer emulation of human parenteral antibiotic dynamics...
