Eco‐Epidemiological Study of Seropositivity Against Rickettsia and Leptospira Agents in Rural Areas of Urabá, Colombia

Tropical Medicine &International Health, EarlyView.
ABSTRACT Introduction Rickettsioses and leptospirosis are infectious diseases often underdiagnosed due to limited knowledge about their epidemiology, pathophysiology, and clinical aspects. Objectives To characterize the seroprevalence and seroincidence of Rickettsia and Leptospira agents and determine their associated factors in rural areas of Urabá ...

Pangenome of Streptomyces sampsonii and Relatives Highlights Horizontal Gene Transfer and Secondary Metabolism in Environmental Adaptation and Ecological Significance

Ecology and Evolution, Volume 16, Issue 9, September 2026.
This study presents a chromosome‐level genome assembly of Streptomyces sampsonii and a pangenome analysis of 95 strains, revealing a highly expansive “open” pangenome. Our results highlight that horizontal gene transfer (HGT) and accessory gene variations drive the evolution of secondary metabolism and environmental adaptation.
