- Research Article | Host-Microbe BiologyProteome-Wide Analysis of Lysine 2-Hydroxyisobutyrylation in Candida albicans
C. albicans is one of the most commonly reported fungal pathogens in mucosal and systemic infections. A better understanding of its growth habits and metabolic processes in the host should help improve defense strategies.

Xiphinematobacter spp. are distinctly evolved intracellular symbionts in the phylum Verrucomicrobia, which includes the important human gut-associated microbe Akkermansia muciniphila and many highly abundant free-living soil microbes. Like Akkermansia sp., Xiphinematobacter sp. is obligately associated with the gut of its hosts,...
- Research Article | Host-Microbe BiologyConsumption of Dietary Fiber from Different Sources during Pregnancy Alters Sow Gut Microbiota and Improves Performance and Reduces Inflammation in Sows and Piglets
Although the direct effects of dietary fiber on gut microbiota composition have been studied extensively, systematic evaluation of different fiber sources on gut health and inflammatory responses of sows and their offspring has rarely been conducted. Excessive reactive oxygen species produced by overactive metabolic processes during late pregnancy and lactation of sows leads to increased endotoxin levels, disordered gut microbiota,...

The ESKAPEE pathogens are the leading cause of health care-associated infections worldwide. Two-component systems (TCSs) can be used as effective targets against pathogenic bacteria since they are ubiquitous and manage various vital functions such as antibiotic resistance, virulence, biofilms, quorum sensing, and pH balance, among others.

The gut microbiota and host genetics are implicated in the pathogenesis of IgAN. Recent studies have confirmed that microbial compositions are heritable (microbiome quantitative trait loci [QTL]).
- Research Article | Host-Microbe BiologyFADU: a Quantification Tool for Prokaryotic Transcriptomic Analyses
Most currently available quantification tools for transcriptomics analyses have been designed for human data sets, in which full-length transcript sequences, including the untranslated regions, are well annotated. In most prokaryotic systems, full-length transcript sequences have yet to be characterized, leading to prokaryotic transcriptomics analyses being performed based on only the coding sequences.

The impact of fungi in the intestine on acute uremia was demonstrated by the oral administration of Candida albicans in mice with the removal of both kidneys. Because fungi in the mouse intestine are less abundant than in humans, a Candida-administered mouse model has more resemblance to patient conditions.
- Research Article | Host-Microbe BiologyNonadditive Transcriptomic Signatures of Genotype-by-Genotype Interactions during the Initiation of Plant-Rhizobium Symbiosis
A sustainable way for meeting the need of an increased global food demand should be based on a holobiont perspective, viewing crop plants as intimately associated with their microbiome, which helps improve plant nutrition, tolerance to pests, and adverse climate conditions. However, the genetic repertoire needed for efficient association with plants by the microbial symbionts is still poorly understood.
- Research Article | Host-Microbe BiologyHeritable Gut Microbiome Associated with Salmonella enterica Serovar Pullorum Infection in Chickens
The present study investigated the association among the host genome, the gut microbiome, and S. Pullorum infection in chickens. The results suggested that the gut microbial structure is altered in S. Pullorum-infected chickens.
- Research Article | Host-Microbe BiologyMetabolic Interactions between Brachypodium and Pseudomonas fluorescens under Controlled Iron-Limited Conditions
Rhizosphere bacteria influence the growth of their host plant by consuming and producing metabolites, nutrients, and antibiotic compounds within the root system that affect plant metabolism. Under Fe-limited growth conditions, different plant and microbial species have distinct Fe acquisition strategies, often involving the secretion of strong Fe-binding chelators that scavenge Fe and facilitate uptake.
