A recent study found that HIV-associated changes in the gut microbiome correlate with peripheral CD4+ T cell counts and are linked to differences in mucosal immune responses and susceptibility to opportunistic infection.

A recent study investigated the effects of chemical pollutants on human gut bacteria in vitro.

In a recent study, Liu, Huang, Guo, McCallum et al. present a method to create functional, customized coronavirus receptors, which could facilitate the development of infection models that do not rely on native receptors.

A recent study demonstrates targeting plasmid-encoded bacterial proteins containing immunoglobulin-like domains to prevent the conjugation and spread of antimicrobial resistance plasmids.

In a recent study, Gaborieau, Vaysset, Tesson et al. developed a method to predict phage–host specificity using genomic data.

In a recent study, Lin et al. uncovered that a single substitution in the bovine influenza H5N1 haemagglutinin protein switches the specificity to human receptors.

A recent study reports the existence of a nitrogen-fixing organelle called the ‘nitroplast’.

Loveridge and Sigala uncover a divalent metal transporter that is required for cellular iron metabolism in Plasmodium falciparum parasites.

A recent study found that soil microbial communities show consistent and predictable responses to extreme climatic events.

A recent study reports that uropathogenic Escherichia coli infection triggers trained immunity in urinary tract tissue, which affects the immune response to subsequent infections.

This study found that the bacterial second messenger cyclic diguanylate (c-di-GMP) has a key role in establishing host–bacteria symbiosis.

A recent study reports the development of a biomarker-responsive engineered bacterium that can diagnose, record and treat inflammatory bowel disease in mice.

A recent study found that the Helicobacter pylori genome evolves during disease progression and that these genomic changes select for effective colonizers of gastric metaplasia.

A recent study found that carbohydrate metabolism by gut microbiota contributes to insulin resistance.

This study investigated the environmental microbiomes of cities by sampling urban beehives, providing insight into the surrounding metagenomic landscape that is relevant to beehive and human health.

This study reports a mechanism of norovirus-induced cell death that promotes viral egress.

A recent study uncovered a relationship between sensory neurons and immune cells in the meninges that facilitates brain invasion by two Streptococcus species and the development of meningitis in mice.

A recent study uncovered a new family of Enterococcus pore-forming toxins that use human leukocyte antigen class I or major histocompatibility complex class I as receptors.

A recent study investigated viral loads in clinical samples with the aim of understanding the distribution of monkeypox virus in the human body and how this distribution may be influencing viral transmission

A recent study provides evidence of non-cell-autonomous disruption of nuclear architecture as a potential cause of COVID-19-associated anosmia.
