This study investigated the effects of the probiotic Lactobacillus acidophilus strain DSM 13241 in dogs with non-specific dietary sensitivity (NSS). Six adult German Shorthair Pointers with NSS consecutively received a control dry diet and the same diet supplemented with the probiotic (6 · 106 cfu/g) for 12 weeks each, followed by another control period of four weeks. Frequency of defecations, faecal quality and nutrient digestibility were determined. Faeces were cultured for Clostridium perfringens, Escherichia spp., lactobacilli and bifidobacteria and quantitative fluorescence in situ hybridisation (FISH) was performed. Feeding the probiotic improved faecal consistency, faecal dry matter and defecation frequency (p < 0.05). Faecal concentrations of culturable lactobacilli and bifidobacteria increased numerically, but not significantly, also the decrease of the numbers of C. perfringens and Escherichia spp. did not reach the level of significance. Results from FISH showed more constant bacterial populations. It can be concluded that L. acidophilus DSM 13241 can stabilise the digestive processes in dogs with NSS.

益生菌嗜酸乳杆菌菌株对非特异性饮食敏感性犬饲料耐受性的影响

本研究调查了益生菌嗜酸乳杆菌菌株 DSM 13241 对非特异性饮食敏感性 (NSS) 犬的影响。六只患有 NSS 的成年德国短毛猫连续接受对照干粮和补充益生菌 (6·106 cfu/g) 的相同饮食，每次持续 12 周，然后是另一个为期 4 周的对照期。确定排便频率、粪便质量和营养消化率。粪便培养产气荚膜梭菌、大肠杆菌、乳酸杆菌和双歧杆菌，并进行定量荧光原位杂交 (FISH)。饲喂益生菌可改善粪便稠度、粪便干物质和排便频率 (p < 0.05)。可培养乳酸杆菌和双歧杆菌的粪便浓度在数值上有所增加，但不显着，也减少了产气荚膜梭菌和埃希氏菌的数量。没有达到显着水平。FISH 的结果显示更稳定的细菌种群。可以得出结论，嗜酸乳杆菌 DSM 13241 可以稳定患有 NSS 的狗的消化过程。
