- Abstract
Background: Probiotics are widely used in dogs but can be associated with alterations in some serum biochemistry test results., Objective: To assess the effect of Enterococcus faecium SF68 administration for 14 days on serum alanine transferase (ALT) and alkaline phosphatase (ALP) activity and total cholesterol and triglyceride concentrations in healthy dogs., Animals: Thirty-six healthy privately owned neutered dogs were randomly allocated, stratified by sex, to control or probiotic groups. Dogs were clinically healthy, with normal physical examination findings, blood, urine, and fecal analyses and ultrasonographic examinations., Method: In this blinded, controlled study E. faecium SF68 was administered to the probiotic group for 14 days. Blood samples were taken from all dogs at days 0, 14, and 28. Serum ALT and ALP activity and total cholesterol and triglyceride concentrations were determined on these 3 days., Results: The probiotic induced no significant changes in mean ALT and ALP activity. Mean cholesterol concentration did not change during probiotic administration but a significant decrease was seen on day 28 (P < .01). Mean triglyceride concentration increased progressively, becoming significant at day 28 (P < .05), with 1 dog developing hypertriglyceridemia., Conclusions and Clinical Importance: E. faecium SF68 would not create confusion when monitoring dogs with hepatobiliary disease because ALT and ALP activity did not change significantly. A significant decrease in cholesterol and significant increase in triglyceride concentrations were seen at day 28 but were not clinically relevant, with 1 dog showing hypertriglyceridemia. A longer trial is warranted to assess if the probiotic effects could be clinically relevant and to assess its potential use in hypertriglyceridemic dogs., (© 2019 The Authors.
