The study reviews and discusses functional aspects of the so-called "acid mantle" of the integumentum commune of domesticated mammals and birds. The problems referred to are closely related to the skin surface-pH and different factors influencing this phenomenon (chemical composition of the skin surface film, secretory activity of apocrine tubular glands, structure of the microflora, lack of skin glands in birds). It becomes evident, that an "acid mantle" of the skin of domesticated animals cannot be verified, and that normal skin-pH (medium values weakly acid to alkaline) exerts no microbicidal effects. Integumental antimicrobial properties may rather be connected with free fatty acids as decomposition products of skin lipids.
该研究回顾并讨论了家养哺乳动物和鸟类体表所谓“酸性外衣”的功能方面。所涉及的问题与皮肤表面pH值以及影响这一现象的不同因素密切相关（皮肤表面膜的化学成分、顶泌管状腺的分泌活动、微生物群落结构、鸟类缺乏皮肤腺）。显而易见，家养动物皮肤的“酸性外衣”无法得到证实，正常皮肤pH值（中等值，从弱酸到碱性）也没有杀菌作用。体表的抗菌特性可能更多地与作为皮肤脂质分解产物的游离脂肪酸有关。
