Dublin in dairy cattle: Review of state of the science.

Abstract

BACKGROUND: subsp.serovar Dublin (Dublin) is a Gram-negative bacterium of increasing importance to the Canadian cattle sector. OBJECTIVE ANIMAL AND PROCEDURE: The objective of this narrative literature review was to provide an overview of the epidemiology ofDublin in cattle, highlight risk factors associated with infection, discuss diagnostic methods, and review prevention and control strategies, with a specific focus on the Canadian context. RESULTS: Approximately 3 to 30% of dairy farms are positive forDublin, depending on the province. This bacterium can cause high levels of morbidity and mortality and is best controlled by preventing carrier cattle from gaining access to uninfected farms. CONCLUSION AND CLINICAL RELEVANCE: Dublin is an emerging pathogen and action is necessary to control its spread.
