Infestation by Sarcoptes scabiei var. bovis in a farmer is reported. He presented with an intensely itching eruption of erythematous papules on forearm, neck and abdomen. An environmental investigation yielded that four of the farmer's cows had mange. Sarcoptes scabiei var. bovis was isolated from skin-scrapings of the cows. Histology from a self-induced lesion revealed that Sarcoptes scabiei var. bovis penetrates the human skin, but does not--in contrast to var. hominis--form burrows. This finding corresponds with the clinical picture. The mite lies subcorneally, compressing the thinned epidermis. The surrounding corneal tissue shows a marked exsudative reaction. The various ways in which mites may infest the human skin are discussed.
报告了一名农民感染牛疥螨的病例。他的前臂、颈部和腹部出现了伴有剧烈瘙痒的红斑丘疹。环境调查发现该农民的四头牛患有疥癣。从牛的皮肤刮片中分离出了牛疥螨。对一处自伤皮损进行的组织学检查显示，牛疥螨可穿透人体皮肤，但与人体疥螨不同的是，它不会形成隧道。这一发现与临床表现相符。螨虫位于角质层下，压迫变薄的表皮。周围的角质组织出现明显的渗出反应。文中讨论了螨虫感染人体皮肤的各种途径。
