This study examines how ceftiofur antibiotic treatment and E. coli inoculation affect the calf fecal microbiome using shotgun metagenomics and single-cell sequencing.

This study identifies mastitis-associated and human opportunistic pathogens in stable flies from a dairy farm, showing they carry bacteria linked to infections but not E. coli O157.

This study uses whole genome sequencing to show that bacteria from Stomoxys flies and manure are phylogenetically intermixed, suggesting flies carry fecal pathogens that contribute to bovine mastitis.

This study compares antimicrobial resistance profiles in bacterial isolates from stable flies and bovine manure, identifying resistance genes and plasmids associated with clinically relevant taxa.

This study examines bacterial communities in stable flies and manure, finding flies host mastitis-associated bacteria with lower diversity than manure.
