Abstract

The effect of natural Corynebacterium pseudotuberculosis infection on wool production and quality in sheep was examined in light of evidence that artificial C pseudotuberculosis infection causes wool production loss. A toxin ELISA was used to identify sheep that had been infected with C pseudotuberculosis. Greasy and clean fleece weights and fibre diameter were compared in infected and uninfected sheep. C pseudotuberculosis infection caused a 3.8 to 4.8% decrease in greasy wool production and a 4.1 to 6.6% decrease in clean wool production. C pseudotuberculosis infection did not affect fibre diameter. The effects of caseous lymphadenitis (the disease caused by C pseudotuberculosis infection) cause an annual loss of about $17 million in wool production to the Australian wool industry.

摘要

鉴于有证据表明人工感染伪结核棒状杆菌会导致羊毛产量下降，因此研究了自然感染伪结核棒状杆菌对绵羊羊毛产量和质量的影响。使用毒素酶联免疫吸附测定法来识别感染了伪结核棒状杆菌的绵羊。对感染和未感染的绵羊的污毛量、净毛量和纤维直径进行了比较。伪结核棒状杆菌感染导致污毛产量下降3.8%至4.8%，净毛产量下降4.1%至6.6%。伪结核棒状杆菌感染不影响纤维直径。干酪性淋巴结炎（由伪结核棒状杆菌感染引起的疾病）给澳大利亚羊毛产业造成的影响致使羊毛年产量损失约1700万美元。
