In the study presented here the relationship between the hygienic condition and the concentration of different air contaminants in two pig fattening houses was investigated. Deficiencies in routine cleaning, which were characterized by an increased soiling of animals and stable surfaces with faeces, led to increased concentrations of airborne dust, airborne endotoxins as well as increased numbers of total airborne bacteria and airborne gram-negative bacteria. However these deficiencies were not reflected by the concentration of airborne Clostridium perfringens which were earlier postulated as an indicator of faecal pollution in the air of cattle barns. Furthermore the results of this study were used to discuss advantages and disadvantages of impingement and impaction for the sampling of airborne microorganisms in animal houses.
在本研究中，对两个生猪育肥舍的卫生状况与不同空气污染物浓度之间的关系进行了调查。日常清洁工作存在不足，表现为动物和畜舍表面粪便污染增加，这导致空气中灰尘、内毒素浓度升高，以及空气中细菌总数和革兰氏阴性菌数量增加。然而，空气中产气荚膜梭菌的浓度并未反映出这些不足，产气荚膜梭菌此前被假定为牛舍空气中粪便污染的指标。此外，本研究结果还用于讨论冲击法和撞击法在动物舍空气中微生物采样方面的优缺点。
