The effect of the probiotic strain Lactobacillus plantarum LS/07 on intestinal bacterial enzyme activities – β-glucuronidase (β-GLUCUR), β-galactosidase (β-GAL), and β-glucosidase (β-GLU) in the prevention of cancer, atherosclerosis and dysbiosis was investigated. Male Sprague-Dawley rats were randomly divided into 12 experimental groups: C (control group), AT (atherosclerotic group), CC (carcinogenic group), and then each group in combination with antibiotics and probiotics individually and each group in double combination on antibiotic and probiotic. In the control group the β-glucuronidase activity did not change throughout the experiment. High fat diet in the atherosclerotic group significantly increased the activity of β-glucuronidase (p<0.001) and β-glucosidase (p<0.01). Azoxymethane application in the carcinogenic group significantly increased β-glucuronidase (p<0.01), but reduced β-glucosidase (p<0.01). Daily application of probiotics individually and in double combination with antibiotics increased the activity of β-galactosidase, and β-glucosidase, and positively decreased the level of β-glucuronidase. In the control antibiotic group β-glucuronidase was significantly increased (p<0.05), and β-glucosidase decreased (p<0.01) which can be caused by a change of microflora in favor of coliform bacteria. These finding indicate the positive effects of probiotic Lactobacillus plantarum LS/07 which allows its use in disease prevention in human and veterinary medicine.
