Identification of novel FosX family determinants from diverse environmental samples.

Objectives: This study aimed to identify novel fosfomycin resistance genes across diverse environmental samples, ranging in levels of anthropogenic pollution. We focused on fosfomycin resistance, and given its increasing clinical importance, explored the prevalence of these genes within different environmental contexts.

Methods: Metagenomic DNA was extracted from wastewater and sediment samples collected from sites in India, Sweden, and Antarctica.

Adaptive expression of phage auxiliary metabolic genes in paddy soils and their contribution toward global carbon sequestration.

Habitats with intermittent flooding, such as paddy soils, are crucial reservoirs in the global carbon pool; however, the effect of phage-host interactions on the biogeochemical cycling of carbon in paddy soils remains unclear. Hence, this study applied multiomics and global datasets integrated with validation experiments to investigate phage-host community interactions and the potential of phages to impact carbon sequestration in paddy soils. The results demonstrated that paddy soil phages harbor a diverse and abundant repertoire of auxiliary metabolic genes (AMGs) associated with carbon fixation, comprising 23.

Of Clams and Clades: Genetic Diversity and Connectivity of Small Giant Clams () in the Southern Pacific Ocean.

Giant clams ( and ) are large marine bivalves occupying tropical and subtropical reefs in the Indo-Pacific. Giant clam populations have declined in many areas of the Indo-Pacific and continue to be threatened by harvesting and environmental change. The small giant clam () occurs throughout the Indo-Pacific and has been subject to several phylogeographic studies across its range.

Vegetable phylloplane microbiomes harbour class 1 integrons in novel bacterial hosts and drive the spread of chlorite resistance.

Bacterial hosts in vegetable phylloplanes carry mobile genetic elements, such as plasmids and transposons that are associated with integrons. These mobile genetic elements and their cargo genes can enter human microbiomes via consumption of fresh agricultural produce, including uncooked vegetables. This presents a risk of acquiring antimicrobial resistance genes from uncooked vegetables.
