Abstract

Metritis is a major uterine disease in dairy cattle, typically oc­curring within 21 days post-partum, and the fourth most com­mon health issue in cows as identified by producers. Currently, little is known of MICs of intrauterine E. coli (EC) to common antimicrobial drugs used to treat metritis in California dairies. The goals of this study were to evaluate factors affecting recov­ery and antimicrobial resistance (AMR) in intrauterine E. coli in post-partum dairy cows with and without metritis from com­mercial California dairy farms.
