Abstract

Frozen longitudinal skin sections taken from the dorsal thoraco-lumbar region of adult Merino sheep that were infested with the sheep-chewing louse were examined by light microscopy. The epidermis of infested sheep exhibited acanthosis due to hyperplasia of the stratum spinosum, and orthokeratosis. The thickness of the uncornified epidermis, the stratum corneum, and the sudanophilic region were significantly greater (P less than 0.005) than equivalent regions in louse-free Merinos and the results suggest that a positive correlation exists between the thickness of each region and the level of louse infestation. The results indicate that the variance in region thickness was greater in lousy than in louse-free sheep (P less than 0.005).

摘要

对取自感染羊嚼虱的成年美利奴绵羊胸腰背部的纵向冰冻皮肤切片进行光学显微镜检查。感染羊的表皮因棘层增生而出现棘皮症和正角化。未角化表皮、角质层和嗜苏丹区域的厚度显著大于（P<0.005）未感染虱子的美利奴羊的相应区域，结果表明每个区域的厚度与虱子感染水平之间存在正相关。结果表明，有虱绵羊的区域厚度方差大于无虱绵羊（P<0.005）。
