Macroscopic and cytological aspects of anal sac content were evaluated in 40 normal dogs and 10 dogs each with pyoderma, Malassezia dermatitis associated with atopic dermatitis and uncomplicated atopic dermatitis. Bacteria isolated from anal sacs were compared with those from abdominal skin and hair in 20 normal dogs and 10 dogs with pyoderma. There was no difference between the groups in anal sac dimension, or in the colour, consistency or presence of granules in their content. Extracellular bacteria were found in higher numbers in diseased animals, whereas intracellular bacteria were observed in 40% of dogs with pyoderma and in only 2.5% of normal dogs. Malassezia spp. were present in 15.7% of dogs, with no difference between groups. Neutrophils were observed in 12.5% of normal dogs, 30% of dogs with Malassezia dermatitis with underlying atopic dermatitis and in 70 and 80% of dogs with pyoderma and uncomplicated atopic dermatitis, respectively. Seven bacterial species were isolated from anal sacs, with no difference between normal dogs and dogs with pyoderma. In five normal animals and in four dogs with pyoderma the same bacterial strains were isolated from anal sacs and from abdominal skin and hair.
对40只正常犬以及各10只患有脓皮病、与特应性皮炎相关的马拉色菌性皮炎和单纯性特应性皮炎的犬的肛门囊内容物进行了大体和细胞学评估。在20只正常犬和10只患有脓皮病的犬中，比较了从肛门囊分离出的细菌与从腹部皮肤和毛发分离出的细菌。各组之间在肛门囊大小、内容物的颜色、稠度或颗粒存在方面没有差异。患病动物体内细胞外细菌数量更多，而在40%的脓皮病犬和仅2.5%的正常犬中观察到细胞内细菌。马拉色菌属存在于15.7%的犬中，各组之间无差异。在12.5%的正常犬、30%患有潜在特应性皮炎的马拉色菌性皮炎犬以及分别在70%和80%的脓皮病犬和单纯性特应性皮炎犬中观察到中性粒细胞。从肛门囊分离出7种细菌，正常犬和脓皮病犬之间无差异。在5只正常动物和4只脓皮病犬中，从肛门囊以及腹部皮肤和毛发分离出相同的细菌菌株。
