carriage by geckos detected within households in Malawi.

was isolated from 23/79 (29.1%) pooled gecko stool samples from households in southern Malawi. Whole genome sequencing of 47 individual isolates within this collection revealed 27 serovars spanning two subspecies.

Breeding Novel Chemistry in Willow: New Hetero Diels-Alder Cyclodimers from Arbusculoidin and Salicortin Suggest Parallel Biosynthetic Pathways.

An investigation of phenolic glycosides extracted from germplasm revealed that arbusculoidin (benzyl 1--β-d-glucopyranosyl-1-hydroxy-6-oxo-2-cyclohexenyl carboxylate) and its enolic 6-glycoside isomer, isoarbusculoidin, are widespread across the Salix family. An analysis of natural hybrid species and progeny from a willow breeding programme demonstrated that the putative biosynthetic pathway leading to the salicinoid family of phenolic glycosides runs in parallel to a "benzyl"-based pathway to arbusculoidin. The introduction of a known Diels-Alder reaction trait from , as well as an acylation trait, into progeny containing both salicyl- and benzyl- pathways caused the formation of all possible hetero-cyclodimers from mixtures of reactive dienone (acyl)glycosides that participated in cross-over reactions.
