Two hundred Merino wether hoggets were used to examine the effect of Corynebacterium pseudotuberculosis infection (caseous lymphadenitis) on wool production and bodyweight. Sheep which were challenged with C. pseudotuberculosis (artificially infected) and not vaccinated against this disease produced 0.20 kg less clean wool than unchallenged controls during the following 12 months. The incidence of sheep with lesions in the group that was vaccinated prior to challenge was 55% lower than in unvaccinated challenged sheep but their wool production was not significantly different from either the controls or the unvaccinated challenged sheep. Vaccinated sheep were also heavier than unvaccinated sheep 12 months after challenge. These results indicate that caseous lymphadenitis infection may reduce wool production.
选用200只美利奴去势幼羊来研究伪结核棒状杆菌感染（干酪性淋巴结炎）对羊毛产量和体重的影响。用伪结核棒状杆菌进行攻毒（人工感染）且未针对该疾病接种疫苗的绵羊，在接下来的12个月里，其净毛产量比未受攻毒的对照组少0.20千克。在攻毒前接种疫苗的组中，出现病变的绵羊发生率比未接种疫苗且受攻毒的绵羊低55%，但其羊毛产量与对照组或未接种疫苗且受攻毒的绵羊相比无显著差异。攻毒12个月后，接种疫苗的绵羊也比未接种疫苗的绵羊体重更重。这些结果表明，干酪性淋巴结炎感染可能会降低羊毛产量。
