This study uses ancient DNA to analyze the evolution of Streptococcus mutans over 8,000 years, showing that some virulence traits emerged with agricultural diets.

This study identifies ancient S. enterica Paratyphi C DNA in 19th-century Mexico, linking it to European strains and showing its persistence in urban settings.

This study identifies loci under selection in Latin American admixed populations, distinguishing between pre- and post-admixture selection, and finds signals related to immunity and energy metabolism.

This study reconstructs ancient viral genomes from Colonial-era remains in Mexico, linking their origin to Africa via the transatlantic slave trade.

The paper evaluates prediction accuracy for eye, hair, and skin pigmentation in admixed Latin Americans using genomic and phenotypic data, finding that Random Forest and regression perform best, and that pigmentation SNPs improve accuracy, especially for skin color.

The paper analyzes ancestry in Latin Americans using haplotype-based methods, finding widespread Converso ancestry and links between Native ancestry and facial features.
