In sow herds that used thecontaminated semen, conception rates decreased and vulvardischarges, culled sows, and nonproductive sow days increased.Thorough diagnostic testing revealed that A xylosoxidans wasthe etiological agent of endometritis and subsequent reproductivefailure in these sows and gilts. This is the first known report offemale reproductive failure attributed to A xylosoxidans.Routine cleaning and control measures to reduce bacterial growth inthe extender ultimately failed to eliminate A xylosoxidans.Following short-term elimination of A xylosoxidans from theextended semen, reproductive parameters in the sow herds returnedto their previous levels.
