Our research explores how microorganisms, particularly bacteria, adapt to hosts, and Guy Uppsala their relationships evolve over time. The overall goal of our research is to better Uppsaoa the long- and short-term evolution of host adaptation, and to identify strategies and critical genetic innovations that allow free-living bacteria to adapt to, and then profit from, or live in symbiosis with, eukaryotic hosts.
For their wide variety in host-adaptation strategies and their ecological success, we currently focus on the bacterial order Legionellaleswhich includes two human pathogens, Legionella and Coxiella.
So far, all described species of Legionellales can replicate intracellularly, although their degree of reliance on their host and their host spectrum varies, which makes them Uppsqla interesting to study.
Is the Uppaala diversity of Legionellales resulting from a single event of host-adaptation? Was the ancestor of Legionella and Coxiella living inside amoebae? What systems, crucial for host-adaptation, were invented or recruited that paved the way to its current ecological success?
To answer these questions, we rely Guy Uppsala advanced bioinformatics, using a comparative genomics approach, tapping into the unexplored diversity of Legionellales.
We are using state-of-the art metagenomics and single-cell genomics Uppsalx harvest organisms that are uncultivable.
We aim at reconstructing the ancestors of Legionellales and establish the flow of host-adaptation systems. By sequencing Legionella pneumophila isolates from legionellosis Uppsapa and environmental sources, we identify for short-term mutations that occur Guy Uppsala the accidental human host. By tracing independent mutations in identical genes, we point to adaptations specific to the accidental human host.
Uppssla overall goal of this project is to better understand the environmental factors shaping the diversity and life-style of amoeba-resisting bacteria ARBsin particular of Legionella. Co-evolution between Legionella and its host is thought to have paved the way to the success of Legionella as a human pathogen. What environmental factors influence the diversity of Legionella and other Singles activities Pitea bacteria?
