摘要

在不同的饲料和环境条件下,研究了一种益生菌对健康犬粪便中选定细菌的影响。在这项研究中,12只狗被饲养在家庭中,在18天内补充一种获得专利的市售粪肠杆菌NCIB 10415 (Enteroferm)菌株。为了尽量减少损失,益生菌产品每天饭前口服一次,剂量为每只狗2g (9.2 x 10(9) CFU)。在补充开始前和18天施用期结束时收集粪便。为了排除污染,所有的粪便都是通过直肠采集的。实验前和实验结束时,用选择性培养基测定新鲜粪便中沙门氏菌、弯曲杆菌和梭状芽胞杆菌的总数。结果表明,使用益生菌粪肠杆菌产品18天后,所有狗的胃肠道菌群都发生了变化。而大多数狗的沙门氏菌和弯曲杆菌计数高于应用前。12只狗中有10只的梭状芽胞杆菌计数明显减少。根据评估犬体内微生物效率的指南,该数据支持了相关的功效效应。然而,益生菌产品对健康狗的有益作用仍然值得怀疑。

The effect of a probiotic Enterococcus faecium product in diets of healthy dogs on bacteriological counts of Salmonella spp., Campylobacter spp. and Clostridium spp. in faeces.

An experiment was conducted to determine the effects of a probiotic on selected faecal bacteria of healthy dogs under different feed and environmental conditions. For the study 12 dogs kept in households were used for an 18-day supplementation with a patented commercially available strain of E. faecium NCIB 10415 (Enteroferm). In order to minimize losses the probiotic product was orally applicated once a day before meals at a dose of 2 g per dog (9.2 x 10(9) CFU). The faeces were collected before the beginning of the supplementation and at the end of the 18-day application period. In order to exclude contamination, all faeces were taken rectally. Before and at the end of the experimental period total Salmonella spp., Campylobacter spp. and Clostridium spp. counts were determined in fresh faeces using selective media. It was demonstrated that the 18-day application of the probiotic E. faecium product induced modifications on the gastrointestinal microflora in all dogs. While Salmonella spp. and Campylobacter spp. counts were in majority of the dogs higher than before the application. Clostridium spp. counts were significantly reduced in 10 of 12 dogs. According to the guidelines for the evaluation of the efficiency of microorganisms in dogs a relevant efficacy effect was supported by this data. However, a beneficial effect of the probiotic product on healthy dogs remains questionable.
