The emergence and diversification of a zoonotic pathogen from within the microbiota of intensively farmed pigs

This study traces the emergence and spread of Streptococcus suis pathogens in pigs, linking their evolution to changes in farming practices and identifying genomic factors associated with pathogenicity.

The host phylogeny determines viral infectivity and replication across Staphylococcus host species

This study shows that host phylogeny explains variation in susceptibility to a bacteriophage across Staphylococcus species.

Absence of Staphylococcus aureus in wild populations of fish supports a spillover hypothesis

This study investigates whether Staphylococcus aureus in wild fish results from spillover or adaptation, finding no S. aureus in wild trout or their environment, supporting spillover from other host populations.

Stable antibiotic resistance and rapid human adaptation in livestock-associated MRSA

This study tracks the evolutionary dynamics of mobile genetic elements in MRSA CC398 over 27 years, showing stable inheritance of resistance genes and rapid adaptation to human hosts.

Mutation rate dynamics reflect ecological change in an emerging zoonotic pathogen

The paper investigates how mutation rates in Streptococcus suis change with ecology and genome size, finding higher mutation rates in invasive disease isolates and a bias towards G/C to A/T mutations in more pathogenic strains.

Genome reduction is associated with bacterial pathogenicity across different scales of temporal and ecological divergence

The paper investigates whether genome reduction is linked to bacterial pathogenicity across different scales of divergence and finds it consistently associated with reduced genome size in pathogens.

A comprehensive portrait of antimicrobial resistance in the zoonotic pathogen Streptococcus suis

This study examines antimicrobial resistance in Streptococcus suis using MIC measurements and whole-genome sequencing, identifying resistance determinants and highlighting the complexity of resistance mechanisms.

Wolbachia, Cardinium and climate: an analysis of global data

The paper analyzes global data on Wolbachia and Cardinium infections in arthropods to assess the impact of temperature on their prevalence across different climates.

The global distribution and spread of the mobilized colistin resistance gene mcr-1

The paper analyzes the global spread of the mcr-1 gene by sequencing isolates and phylogenetic analysis, finding all mcr-1 elements originated from a single mobilization event in the mid-2000s.
