The ability of probiotic strain Lactobacillus plantarum LS/07 to modify the activity of intestinal bacterial enzymes - β-glucuronidase (β-GLUCUR), β-galactosidase (β-GAL), and β-glucosidase (β-GLU) in prevention of chronic diseases - cancer, atherosclerosis and dysbiosis was investigated. The male Sprague-Dawley rats were randomly divided into 12 experimental groups: controls groups - C (control), AT (atherosclerotic), CC (carcinogenic), dysbiotic groups - each group in combination with antibiotics (ATB), probiotics groups - in combinatioan with probiotic (PRO) alone, and each group with combination of antibiotic and probiotic (ATB+PRO). In the control group the β-glucuronidase activity did not change throughout the experiment. High fat diet in atherosclerotic group significantly increased the activity of β-glucuronidase (P<0.001) and β-glucosidase (P<0.01). Azoxymethane application in carcinogenic group significantly increased β-glucuronidase (P<0.01), but reduced β-glucosidase (P<0.01) activity. Daily application of probiotics alone and in combination with antibiotic increased β-galactosidase, of β-glucosidase, and decreased β-glucuronidase activity. In control antibiotic group we observed significant increase in β-glucuronidase (P<0.05) and decreased β-glucosidase (P<0.01) activity which can be caused by the change of microflora in favor of coliform bacteria. These findings indicate the positive effects of probiotic Lactobacillus plantarum LS/07 and suggest its use in disease prevention in human medicine and some animal species.
