Abstract 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.

Abstract The aim of this study was to investigate the influence of prebiotic inulin diet intervention on the activity of β-glucuronidase and counts of coliforms and lactobacilli in fresh caecal digesta, cytokine levels (IL-6, IL-8) and transcription nuclear factor kappa beta (NFkB) activities in the colon tissue and blood samples of rats with dextran sulphate sodium (DSS) induced acute colitis. Male Sprague-Dawley rats (8 per group) were randomly divided into three groups: Control, Acute colitis and Prebiotic. Colitis was induced using 5% DSS in drinking water for 7d. DSS application significantly increased the activity of β-glucuronidase (p<0.001), increased counts of coliform bacteria and decreased lactobacilli count (p<0.05) in comparison to the control group. Serum and tissue levels of IL-6 and IL-8 as well as tissue NFkB activities showed an increased expression in the acute colitis group. These results correspond to the average value of the disease activity index score (DAI) and revealed the maximum DAI score (6.5) in the acute colitis group. A decrease in the DAI score (4.13) was observed after application of the prebiotic inulin. Inulin diet intervention positively modified the number of microorganims and decreased β-glucuronidase activity. Colon tissue activities of NFkB were significantly suppressed (p<0.001). The synthesis of proinflammatory cytokines IL-6 (p<0.01) in the serum and in the colon tissue, as well as tissue IL-8 (p<0.05) in the prebiotic group were downregulated. These findings indicate that the dietary intake of inulin suppressed the expression of the observed markers, which play an important role in the inflammatory process, which predisposes to the use of inulin in the prevention or treatment of acute colitis in human and veterinary medicine.

The aim of the present study was to evaluate the effect of the new probiotic strain Lactobacillus plantarum on chemically induced carcinogenesis in rats. Sprague dowley rats (n = 33) were divided into control and experimental groups and were fed a conventional laboratory diet. In the experimental group, rats were treated with the probiotic at the dose of 1 × 109 CFU (colony-forming units)/ml. Two weeks after the beginning of the trial, N,N-dimethylhydrazine (chemical carcinogen) injections were applied s.c. at the dose of 21 mg/kg b.w., 5 × weekly. At the end of the 8-month experimental period, faeces samples were taken from the rats and used for laboratory analysis. The counts of lactobacilli and coliforms and bacterial enzyme activity were determined. The probiotic strain L. plantarum as single species or in combination with oil (Lini oleum virginale) decreased the count of total coliforms and increased lactobacilli in faeces of rats. Application of probiotic microorganisms significantly (P < 0.05) decreased the activities of bacterial enzymes (β-galactosidase and β-glucuronidase) compared to the control group rats. The results of this study indicate that probiotic microorganisms could exert a preventive effect on colon carcinogenesis induced by N,N-dimethylhydrazine.

Abstract To evaluate the efficiency of the probiotic strain Lactobacillus plantarum LS/07 in dextran sulphate sodium (DSS) induced acute colitis selected biochemical (activity of β-glucuronidase), microbiological (counts of lactobacilli and coliforms), and immunological (IL-6, IL-8, IL-13, NF-κB, MPO) parameters were assessed. Sprague-Dawley rats were divided into groups: Control, Acute colitis, and Probiotic. Acute colitis was induced using 5% DSS in drinking water for 7d. DSS induced an inflammatory process in the colonic tissue, increased the activity of β-glucuronidase (p<0.001), increased the counts of coliform bacteria and decreased lactobacilli counts (p<0.05), and activated the production of the measured parameters (NF-κB, MPO, IL-6, IL-8) except of IL-13. Lactobacillus plantarum LS/07 in the diet alleviated the DSS induced inflammatory process by inhibiting the production of IL-6, IL-8, the activities of NF-κB and MPO, and stimulated the production of IL-13. The probiotic reduced the activity of β-glucuronidase (p<0.05), increased lactobacilli counts and decreased coliform bacteria. These results indicate that dietary intake of Lactobacillus plantarum LS/07 suppressed the expression of markers playing an important role in the inflammatory process. We conclude that the anti-inflammatory properties of Lactobacillus plantarum LS/07 makes its suitable for the prevention or treatment of colitis.

Vitamin B2, also known as riboflavin, is essential for maintaining human health. The purpose of this study was to isolate novel lactic acid bacteria that overproduce vitamin B2 and to validate their potential as probiotics. In this study, Lactobacillus plantarum HY7715 (HY7715) was selected among lactic acid bacteria isolated from Kimchi. HY7715 showed a very high riboflavin-producing ability compared to the control strain due to the high expression of ribA, ribB, ribC, ribH, and ribG genes. HY7715 produced 34.5 ± 2.41 mg/L of riboflavin for 24 h without consuming riboflavin in the medium under optimal growth conditions. It was able to produce riboflavin in an in vitro model of the intestinal environment. In addition, when riboflavin deficiency was induced in mice through nutritional restriction, higher levels of riboflavin were detected in plasma and urine in the HY7715 administration group than in the control group. HY7715 showed high survival rate in simulated gastrointestinal conditions and had antibiotic resistance below the cutoff MIC value suggested by the European Food Safety Authority; moreover, it did not cause hemolysis. In conclusion, HY7715 could be considered a beneficial probiotic strain for human and animal applications, suggesting that it could be a new alternative to address riboflavin deficiency.

In this study, the effects of selenium added to the diets of Astacus leptodactylus at different ratios on paraoxonase (PON) and arylesterase enzyme activities (ARE) in the hepatopancreas and gonad tissues were investigated. In this study, control (K), trial 1 (D1), trial 2 (D2) and trial 3 (D3) were prepared at the selenium levels of 0,3, 0,6, 0,9 and 1,2 mg/kg, respectively. The crude protein and total energy levels of experimental diets were equalized. 12 ponds in 2 × 2 × 1 m dimensions were used. 75 female and 25 male crayfish were stocked in each pond (totally 1200 crayfish). This study was carried out in triplicate. The crayfish were fed twice a day during 9 months. PON and ARE enzyme activities were investigated in the tissue samples taken monthly from the crayfish. During the trial, significant differences were observed in the PON and ARE enzyme activities in the hepatopancreas and gonad tissues. The PON and ARE enzyme activities increased statistically significant in the crayfish tissues during the breeding season and incubation period. This increase was found to be statistically different in the D1, D2 and D3 groups compared to the control group. In conclusion, selenium had positive effects on PON and ARE enzyme activities of A.leptodactylus during its mating, pleopodal egg laying and pleopodal egg carrying periods.

The aim of the present study was to determine the effects of age and diet (breast milk, formula milk and weaning diet) on metabolic activities in faecal samples from infants aged 1 week to 1 year, and to compare these findings with activities found in samples from adults. Such activities can provide valuable information on functional changes in the microbiota that may have significance for the health of the host. Fresh faecal samples were collected from forty-four breast-fed infants (twenty-four males, twenty females) and thirteen formula-fed infants (three males, ten females) throughout the first year of life. The samples were analysed for protein-breakdown products, including the faecal concentrations of NH3, phenol and p-cresol, and faecal bacterial enzyme activities. There was wide individual variation in all variables measured; however, the values in infants were substantially lower then those found in adults. In pre-weaned infants, faecal NH3 concentration and β-glucuronidase activity were the only endpoints that were significantly different in breast-fed and formula-fed infants (P<0·001 and P<0·05 respectively). This was not apparent after weaning. There was a significant difference between the breast-fed and formula-fed weaned groups and their pre-weaned counterparts only for NH3 (P<0·05). β-Glucuronidase activity and phenol concentration were significantly (P<0·01) greater in weaned breast-fed infants compared with pre-weaned breast-fed infants. No differences were observed between pre-weaned and weaned formula-fed infants for any of the variables except for NH3 concentration. It can be concluded from the present study that there are significant differences in two faecal characteristics between breast- and formula-fed infants and that changes occur as the infants grow older and are weaned onto solid foods.

The objective of our research was to determine the effects of colostrum supplementation with clinoptilolite on concentrations of serum proteins, minerals and enzyme activities in newborn calves. Twenty newborn calves that were divided into control group (n=10) which received colostrum and experimental group (n=10) that received colostrum with 0.5% clinoptilolite added in the first three colostrum meals were studied. Blood samples were collected from jugular vein in vacutainer tubes from all calves prior to colostrum intake and after that, at 24 and 48 h after birth. Samples were analyzed for total protein, albumin, α1-globulin, α2-globulin, ß-globulin, γ-globulin, calcium, phosphorus, magnesium, iron, gamma glutamyltransferase, alanine aminotransferase, aspartate aminotransferase and alkaline phosphatase. Clinoptilolite supplementation had significant effect (p<0.0006) on serum iron concentrations in experimental (27.64±3.78 µmol/l) vs control group (8.93±1.26 µmol/l) after 48h. GGT values were also significantly higher (p<0.04) in E (163.60±26.67 U/l) than in C group (84.01±19.77 U/l) at 48h after parturition. Other parameters analyzed were unaffected by clinoptilolite treatment. Obtained data revealed that colostrum supplemented with clinoptilolite had positive effects on some mineral parameters.

In the present study, the effect of different salt concentrations on some quality properties such as the total number of coliform bacteria, texture, cooking loss, total salt content, metmyoglobin, pH, the water activity of steaks prepared from longissimus dorsi muscle of fresh beef was investigated. For this purpose, steaks prepared from longissimus dorsi muscle were dipped in marination brine in four different concentrations; 0% (control group), 1.5% NaCl, 2% NaCl and 2.5% NaCl, and marinated for 24 hours at +4 °C. The initial crude protein, crude fat, pH, moisture, and ash contents of beef were determined as 20.50%, 5.80%, 6.13, 72.63%, 1.07%, respectively. In the cooked meat samples, the hardness, chewiness and gumminess of the samples marinated with 1.5% and 2% NaCl was found to be higher than the control group. Metmyoglobin content of the meat samples marinated with NaCl is lower than the control group. The results revealed that the total number of coliform bacteria decreased drastically in parallel with the increase in salt concentration. As a result, the changes in the quality of the bovine longissimus dorsi muscle with different salt concentrations and marination were investigated, and positive effects on the textural properties and coliform bacterial load of the meat were observed.

BackgroundThe present study aimed to evaluate the effects of the probiotic strain Lactobacillusacidophilus D2/CSL (CECT 4529) on nutritional condition and faecal quality in cats.MethodsTen healthy adult cats from the same cattery were included (aged >9 months; male:female sex ratio=3:7). The animals were randomly assigned to a control group (CTR; n=5; male:female=1:4; room 1: 16 m2) and to a treated group (LACTO; n=5; male:female=2:3; room 2: 16 m2) receiving the same commercial dry diet. The LACTO group diet was supplemented with the probiotic (5 x 109 cfu/kg feed at least). A five-week experimental period was applied, and nutritional status was monitored by bodyweight (BW) and body condition score (BCS). Faecal quality was evaluated using faecal score (FS) and faecal moisture (FM) parameters. Plate counts of some faecal bacteria species were carried out. The data obtained were analysed using MIXED, GLM and NPAR1WAY procedures (SAS V.9.4; P≤0.05).ResultsThe two groups did not show differences in BW and BCS data. A clear effect of the probiotic supplementation on FM was recorded (LACTO 44 per cent v CTR group 46 per cent; P=0.04). FS in the LACTO group (3.35) was close to ideal values (2–3) in comparison with the CTR group (3.75). Positive effects of Lacidophilus D2/CSL have been recorded in terms of increase in faecal lactobacilli counts and reduction in faecal coli counts.ConclusionsThis study’s preliminary results describe how inclusion of Lacidophilus D2/CSL (CECT 4529) probiotic strain in cats’ diets could effectively improve faecal quality parameters and consequently gut health in adult healthy cats.

Objective. Uric acid (UA) activates the NLRP3-ASC-caspase-1 axis and triggers cascade inflammatory that leads to hyperuricemic nephropathy and hyperuricemia-induced renal tubular injury. The original study aims to verify the positive effects of the traditional Chinese medicinal formula Shizhifang (SZF) on ameliorating the hyperuricemia, tubular injury, and inflammasome infiltration in the kidneys of hyperuricemic lab rats. Method. Twenty-eight male Sprague-Dawley rats were divided into four groups: control group, oxonic acid potassium (OA) model group, OA + SZF group, and OA + Allopurinol group. We evaluated the mediating effects of SZF on renal mitochondrial reactive oxygen species (ROS) and oxidative stress (OS) products, protein expression of NLRP3-ASC-caspase-1 axis, and downstream inflammatory factors IL-1β and IL-18 after 7 weeks of animals feeding. Result. SZF alleviated OA-induced hyperuricemia and inhibited OS in hyperuricemic rats (P<0.05). SZF effectively suppressed the expression of gene and protein of the NLRP3-ASC-caspase-1 axis through accommodating the ROS-TXNIP pathway (P<0.05). Conclusion. Our data suggest that SZF alleviates renal tubular injury and inflammation infiltration by inhibiting NLRP3 inflammasome activation triggered by mitochondrial ROS in the kidneys of hyperuricemic lab rats.
