Uterine Culture Collection: Swab/Brush

Culture of the uterus is performed as part of the routine breeding soundness examination in the mare. Culture may be performed via a standard uterine culture swab, from secretions obtained from a uterine brush, or from fluid obtained from a low volume uterine lavage. The method for performing a uterine culture depends on a number of factors, such as cost, time to perform the procedure, and availability of equipment. The best time to perform a uterine culture may be debatable, but is most often performed in early estrus. Culture swabs should be immediately plated onto blood agar or other appropriate media. The chapter discusses the step by step procedures for uterine culture collection and outlines the equipment and supplies needed for this purpose.
