Probiotic utilization is becoming increasingly popular in veterinary medicine. However, only few probiotic products are available commercially for use in dogs in our market. Therefore, the aim of our study was to determine the properties of new potential probiotic Lactobacillus fermentum AD1 strain-own canine isolate and to investigate its effect on several microbiological and biochemical parameters in healthy dogs. The strain expressed in vitro survival by pH 3.0 after 3 h (86.8%) and in the presence of 1% bile (75.4%). The AD1 strain adhered to the canine and human intestinal mucus. It was sensitive to commonly used antimicrobials. Fifteen healthy dogs were supplemented with 10(9) L. fermentum AD1 for 7 days. At the end of AD1 strain application, numbers of faecal lactobacilli and enterococci increased significantly in the canine faeces. Significant increase of total protein and total lipid and significant reduction of glucose in serum of dogs were noted. These data indicate that L. fermentum AD1 survive transit through the canine gastrointestinal tract, and populate the colon and probably increased absorption of some nutrients. Whether longer time of its application lead to the same results as well as its potential to improve immune function in dogs remains to be determined. (C) 2006 Elsevier Ltd. All rights reserved.
