Enteric bacteria associated with bloodstream infections are attracted to human serum through L-serine and the chemoreceptor Tsr, and in an enterohemorrhagic lesion model use chemotaxis to invade damaged vasculature.

An integrated empirical paradigm tracing immune strategies, underlying mechanisms and infection outcomes across reservoir host-pathogen systems, their specific ecological contexts, life-history features, and coevolutionary dynamics can reveal the actual patterns and processes underlying spillover in the wild.

Nemo-like kinase is a key protein promoting the pathogenesis of spinal and bulbar muscular atrophy.

Fitting a simple model of COVID-19 transmission to crowdsourced case report data allowed the estimation of mean cluster size and transmission rates in Canadian schools, as well as determining which interventions are most likely to limit transmission.

Ketogenic diet protects against coronavirus-infected aged mice, which, like humans, are significantly more susceptible to infections, by deactivating NLRP3 inflammasome, reducing pathogenic monotypes, and expanding γδ T cells in the lung.

Parasites with pathogenic variant surface antigens are common in adult malaria patients with a naive immune status.
