Asthma is a ubiquitous disease with a broad range of clinical phenotypes. To better understand the complex genetic and environmental interactions underlying asthma, we compared the gene-gene interactions of four genetically distinct mouse strains that demonstrate biologically distinct responses to allergen. Using DNA microarrays and knock-out mouse studies, we showed that CCR5 plays a definitive role in the development of ovalbumin-induced allergic airway inflammatory disease. In addition, gene expression profiling data have revealed other potential novel targets for therapeutics-based research and has enhanced the understanding of the molecular mechanisms underlying the etiology of "asthma."

The plant rhizosphere microbiome plays a crucial role in plant growth and health. Within this microbiome, bacteria dominate, exhibiting traits that benefit plants, such as facilitating nutrient acquisition, fixing nitrogen, controlling pathogens, and promoting root growth. This study focuses on designing synthetic bacterial consortia using key bacterial strains which have been mapped and then isolated from the sorghum rhizosphere microbiome.

Commercial probiotics are often formulated as multi-strain cocktails, but the effects of social interactions, particularly between strains of a species, are often neglected, despite their potential to contribute to higher-order interactions where these interactions could affect those with a third party. In this study, we investigated the probiotic potential of a collection of Bacillus subtilis strains against Salmonella Typhimurium in single-strain and mixed cultures. The results indicate a promising probiotic potential of B.

Herbicide-treated soil as a reservoir of beneficial bacteria: microbiome analysis and PGP bioinoculants in maize.

Environ Microbiome

December 2024

Background: Herbicides are integral to agricultural weed management but can adversely affect non-target organisms, soil health, and microbiome. We investigated the effects of herbicides on the total soil bacterial community composition using 16S rRNA gene amplicon community profiling. Further, we aimed to identify herbicide-tolerant bacteria with plant growth-promoting (PGP) capabilities as a mitigative strategy for these negative effects, thereby promoting sustainable agricultural practices.

Obesity is a global health concern, affecting individuals of all ages and genders. One promising strategy to combat obesity is by addressing gut microbiota dysbiosis, with probiotics being a reliable intervention. However, single-strain probiotics may not effectively modulate the complex microbial communities in the gut, suggesting the need for multi-strain approaches.
