Abstract
Bull semen is commonly contaminated with mycoplasmas. To determine the source of contamination, semen and the genital tracts of 45 artificial insemination bulls were cultured for these organisms. The results indicate that mycoplasmas colonize the prepuce and the distal part of the urethra. Only rarely were they found in the ampullae or seminal vesicles. In 92% of the bulls with contaminated semen the same Mycoplasma species or Ureaplasma diversum was isolated from the prepuce and urethral orifice as was found in the semen. This suggests that the prepuce and distal urethra is the source of contamination. Colonization of the genital tracts with Mycoplasmas or U. diversum was not associated with histological changes.
摘要
公牛精液常被支原体污染。为确定污染来源，对45头用于人工授精的公牛的精液和生殖道进行了这些微生物的培养。结果表明，支原体定殖于包皮和尿道远端。在壶腹或精囊内很少发现它们。在92%精液受污染的公牛中，从包皮和尿道口分离出的支原体种类或解脲脲原体与精液中发现的相同。这表明包皮和尿道远端是污染来源。支原体或解脲脲原体在生殖道的定殖与组织学变化无关。
