Start date
2007
End date
2012
Objective
To assess resistance among Salmonella and E. coli originating from bovine sources to 4th generation cephalosporins over time. NARMS isolates will be used and results will be compared to previous studies as well as to 17 other antimicrobials.

Secondly, to assess resistance among Campylobacter jejuni, Campylobacter coli, Enterococcus faecalis and Enterococcus faecium originating from bovine and porcine sources to macrolides over time.

More information
Approach: Bacterial will be cloned and a single clonotype will be tested for resistance to a custom made panel of antimicrobials important in human and veterinary medicine using the semi automated broth microdilution sensititre system.
