Sequencing tracks animal-to-human transmission of bacterial pathogens
Date:3/25/2013

mparing single difference in nucleotides in the two sequences (single nucleotide polymorphisms) they were able to reach conclusions about the identity of the pathogens and the routes of infection.

The researchers emphasize that while whole genome sequencing cannot replace other more traditional types of diseases analysis it can greatly increase the ability of scientists to distinguish between different pathogens as the cause of disease.

"Our findings demonstrate that the MRSA strains we studied are capable of transmission between animals and humans, which highlights the role of livestock as a potential reservoir of antibiotic-resistant bacteria," remarked Ewan Harrison, one of the lead authors of the study.
