This test is intended to screen for strongly beta-hemolytic Brachyspira species only. If weakly beta-hemolytic Brachyspira species are of clinical concern, please select Routine Brachyspira Culture. Due to the inherently high level of background flora in fecal samples, the ISUVDL Bacteriology Section does not pool samples for Brachyspira culture. Samples are set up individually, reported individually, and charged individually.
