New Bayesian Method Improves Wastewater-Based Influenza Surveillance by Selectively Querying Additional Data Sources
Researchers have developed a Bayesian Selective Latent Inference (BSLI) method that uses wastewater monitoring as a primary data source for tracking influenza, then strategically decides whether to query additional clinical surveillance streams. The method addresses a key limitation of wastewater surveillance alone: it cannot fully capture human disease burden without supplementary data. The approach is significant because it could enable earlier detection of flu outbreaks while maintaining scientific rigor about when data is insufficient for reliable conclusions.
A new computational method called Bayesian Selective Latent Inference (BSLI) has been developed to optimize influenza surveillance by starting with wastewater data and intelligently deciding when to incorporate additional clinical reporting streams. Wastewater monitoring can reveal community flu circulation before cases appear in clinical reports, but wastewater data alone cannot fully represent actual human disease burden. The BSLI method maintains a probabilistic model of latent disease burden and data identifiability, includes explicit scientific gates to certify when conclusions are reliable, and uses cost-calibrated decision theory to optimize which additional data sources to query and when to abstain from making predictions. Testing on a public benchmark with nearly 6,000 forecasting episodes demonstrated that BSLI improved cost-performance trade-offs while conservatively avoiding predictions when source ambiguity made conclusions scientifically indefensible. The method's theoretical properties—including variational inference, answerability certification, and Bellman optimality—have been formally proven.

Gut Bacteria Enzyme Found to Break Down Heat-Processed Food Compounds, Producing Novel Biogenic Amines
Researchers have discovered that an enzyme in common gut bacteria can degrade N-epsilon-carboxymethyllysine (CML), a compound formed during thermal food processing, producing previously unknown biogenic amines. The enzyme, ornithine decarboxylase SpeC from enterobacteria, acts on CML and related modified lysine derivatives through a low-level 'underground' catalytic activity. This finding suggests a previously unrecognized communication axis between thermally processed dietary compounds and gut microbial physiology, with potential implications for host health.
Full-Length Gene Sequencing Reveals Two Distinct Bacterial Communities in Black-Legged Ticks Expanding Into Canada
Researchers used Oxford Nanopore full-length 16S rRNA gene sequencing to characterize the microbiome of Ixodes scapularis black-legged ticks collected in Nova Scotia, Canada, distinguishing between tick-adapted bacteria and environmentally acquired bacteria. The study comes as I. scapularis — the primary vector of Lyme disease — is rapidly expanding northward into Canada due to climate change. The findings suggest that environmentally derived bacteria in tick microbiomes are not mere contamination, which has implications for how tick microbiome data is collected and interpreted across surveillance studies.
Study Identifies Metabolic Link Between Cell Envelope Stress and Biofilm Formation in Bacteria
Researchers have discovered that the metabolite acetyl-CoA directly inhibits enzymes that degrade the bacterial signaling molecule c-di-GMP, connecting cell envelope biosynthesis stress to biofilm formation in Pseudomonas aeruginosa. The study found that sub-inhibitory concentrations of antibiotics targeting early peptidoglycan biosynthesis — but not other antibiotic classes — elevate c-di-GMP levels by reducing phosphodiesterase activity, with acetyl-CoA competing for the enzyme active site. Because the relevant enzyme domain is broadly conserved across bacterial species, this checkpoint mechanism may be widespread and could have implications for understanding antibiotic-induced biofilm responses.
