A little guide for advanced search:

  • Tip 1. You can use quotes "" to search for an exact expression.
    Example: "cell division"
  • Tip 2. You can use + symbol to restrict results containing all words.
    Example: +cell +stem
  • Tip 3. You can use + and - symbols to force inclusion or exclusion of specific words.
    Example: +cell -stem
e.g. searching for members in projects tagged cancer

About

Original art: HEXICO  (El Gato y La Caja)

The ultimate goal of the Microbial Paleogenomics G5 unit is to investigate how pathogens and human microbes emerged, spread and changed at the genomic level over the course of human history, and use this information to better understand the complexity of modern infectious diseases and human commensal microbes. To do so, we bring together and/or borrow tools, concepts and approaches from distinct fields, such as,  ancient DNA, phylogenetics, microbial genomics, evolution, population genetics, bioinformatics, history and archaeology. Most of current knowledge about infectious diseases and human commensal microbiota derive from studies on modern microbial strains. Our projects will aim at using genomic information from ancient pathogens and oral microbes to reconstruct where and when these species were in the past and determine the relationships and genomic changes that took place over time from strains in the past to those that thrive in modern times. We will also use these approaches to investigate the mobility and spread of microbial species in relation to their human host populations, and the roles played by different historical processes in shaping our microbial makeup.

Our main focus and study model will be the human populations from the Southern Cone of the Americas, which will be analyzed over large temporal scales, from the earliest human populations in the continent, until modern societies. This is motivated by the fact that we know very little about the pathogens and microbes that were associated to pre-Columbian populations, including those from this region, and to which extent this picture changed after the Agricultural transition, the Discovery of the Americas, the colonization process and the post-industrial era. Moreover, it represents an independent and distinct model to study how infectious diseases and human microbes emerged, evolved, and spread, because these populations have been isolated from other worldwide populations for the past 15k to 20k years.
