[Airborne microorganisms in animal stables. 1. Anaerobic airborne bacteria in a calf stable with special regard to Clostridium perfringens].
The total number of airborne anaerobic bacteria with special regard to Clostridium perfringens (C. perfringens) as well as the total number of airborne aerobic bacteria was estimated indoor and outdoor of a calf stable. 65 indoor samples and 63 outdoor samples were collected by using a 6 stage Andersen sampler. The total number of airborne anaerobic bacteria of the indoor samples ranged from 3,216 to 24,222 CFU/m3 (Colony Forming Units) with a part of 4 to 1179 CFU/m3 of C. perfringens. 734 to 1588 CFU/m3 of airborne anaerobic bacteria were found in the outdoor samples. The number of C. perfringens CFU varied between 2 and 15 CFU/m3. The total number of airborne aerobic bacteria indoor ranged from 9,166 to 53,932 CFU/m3, outdoor from 2,443 to 21,205 CFU/m3. Furthermore the results suggested that C. perfringens is suitable for indicating the bacterial contamination of air by faeces of animals.
