Histopathological effects of ectoparasites on integument were examined for a wild population of the side-blotched lizard Uta stansburiana. These included the trombiculid Neotrombicula californica, the pterygosomatid mite Geckobiella texana; the macronyssid mite Ophionyssus natricis (Macronyssidae) and the ixodid tick Ixodes pacificus. A diffuse inflammatory response occurred at the site of chigger and tick attachment which consisted of histiocyte, heterophil, fibroblast and lymphocyte infiltration that often extended into the dermis. Granuloma formation also was noted. The most prevalent parasite was N. californica which frequently occurred in large aggregations above the eyelids. Ectoparasites were most abundant from February through April.
对侧斑蜥蜴（Uta stansburiana）的野生种群，研究了体表寄生虫对其皮肤组织病理学的影响。这些寄生虫包括加利福尼亚新恙螨（Neotrombicula californica）、德克萨斯壁虎螨（Geckobiella texana）、食蜗巨刺螨（Ophionyssus natricis，巨刺螨科）和太平洋硬蜱（Ixodes pacificus）。恙螨和蜱附着部位出现弥漫性炎症反应，由组织细胞、嗜异性粒细胞、成纤维细胞和淋巴细胞浸润组成，常延伸至真皮。还观察到肉芽肿形成。最常见的寄生虫是加利福尼亚新恙螨，常大量聚集在眼睑上方。体表寄生虫在2月至4月最为丰富。
