Symbiotic bacterium affects reproduction of biological control insect
Researchers have revealed that the symbiotic bacterium Rickettsia induces strong cytoplasmic incompatibility (CI) in the predatory mirid bug, Nesidiocoris tenuis, which preys on agricultural pests such as whiteflies and thrips.

In lab tests, dietary zinc inhibits AMR gene transmission
Genes responsible for antimicrobial resistance (AMR) can spread from microbe to microbe through plasmids, and this lateral transfer occurs in the gut - but transmission of some AMR plasmids may be inhibited by dietary zinc supplements.

TIny microbe rewired to upcycle excess carbon dioxide
Researchers have rewired a microbe to help tackle greenhouse gases in the atmosphere: It takes in carbon dioxide (CO2) gas and produces mevalonate, a useful building block for pharmaceuticals.

Researchers develop an efficient host-vector system for a model archaeon by solving CRISPR-based host-plasmid conflict
The replicase gene of pRN1, an archaeal cryotic plasmid, carries a DNA segment to be targeted by the host I‐A CRISPR system, and the CRISPR-based host-plasmid conflict is responsible for instability of pRN1‐derived vectors in the archaeon Saccharolobus islandicus REY15A.

Gull droppings undermine efforts to control spread of colistin-resistance genes
Gull droppings at beaches in the Porto region of Portugal are riddled with bacteria that are resistant to the ‘last-resort’ antibiotic colistin, undermining efforts in the livestock sector to reduce colistin-resistance, according to a paper published in Environmental Microbiology, an Applied Microbiology International publication. Researchers at the ...
