Disclosures: Disclosures to report. Unrestricted research grant from Bayer Animal Health. Canine Monocytic Ehrlichiosis (CME) is a major tick-borne disease worldwide. Diagnosis of CME can be challenging, as the patients may present with variable, often non-specific, clinical signs associated with different stages of the infection, or co-infections. Ehrlichia canis is the etiological agent. Diagnosis of CME is generally supported by detection of E. canis antibodies either by indirect 2015. Questionnaires were used to study clinic related factors which might influence AMU by companion animal veterinarians. Antimicrobial usage data were converted to the number of Defined Daily Dosages (DDDs) with a standardized Dutch database built for this purpose. A number of DDDs during a specified period (mostly a year) represents the number of days during that period that an average dog, cat or rabbit in a clinic is treated with AM's. DDDs were differentiated in first (not selecting for ESBLs), second (might select for ESBLs) and third choice AM's (critically important to public health; i.e. third-and fourth-generation cephalosporins and fluoroquinolones).
