An epidemiologic study was designed to investigate the increasing number of cases of canine blastomycosis being reported in Wisconsin. From January 1980 through July 1982, 200 cases of canine blastomycosis from 39 Wisconsin counties were examined to assess epidemiologic and environmental aspects of this disease. Based on a survey of 176 dog owners, principal disease characteristics for canine blastomycosis were anorexia, lethargy, shortness of breath, chronic cough, and weight loss. The greatest number of cases of canine blastomycosis was in the northwest, north central, northeast, central, and southeast regions of Wisconsin. The northeast and central regions were determined to be new enzootic areas. Sporting breeds accounted for the largest percentage of cases among the various breeds of dogs in Wisconsin. Most of the affected dogs were 3 years old or younger and there was no apparent sexual predilection. Canine blastomycosis was diagnosed more frequently from late spring through late fall. Enzootic areas, except for the southeast region of Wisconsin, were located where the soil was sandy and acid. The results of this study suggested a possible association of enzootic areas with waterways, especially impoundments.
一项流行病学研究旨在调查威斯康星州报告的犬芽生菌病病例数量不断增加的情况。从1980年1月到1982年7月，对来自威斯康星州39个县的200例犬芽生菌病病例进行了检查，以评估该疾病的流行病学和环境方面。基于对176名狗主人的调查，犬芽生菌病的主要疾病特征为厌食、嗜睡、呼吸急促、慢性咳嗽和体重减轻。犬芽生菌病病例最多的地区是威斯康星州的西北部、中北部、东北部、中部和东南部。东北部和中部地区被确定为新的动物疫病流行区。在威斯康星州的各种犬种中，运动犬种的病例占比最大。大多数受影响的狗年龄在3岁及以下，且没有明显的性别偏好。犬芽生菌病在晚春到晚秋期间被诊断出的频率更高。除了威斯康星州东南部地区外，动物疫病流行区位于土壤为沙质且呈酸性的地方。这项研究的结果表明，动物疫病流行区可能与水道，尤其是蓄水池有关。
