Bioflora Probiotic in Immunomodulation and Prophylaxis of Intestinal Bacterial Translocation in Rats

The immunomodulator effect of Bioflora probiotic on T (CD4+) and B (CD20) lymphocytes in gastrointestinal mucosa and intestinal bacterial translocation was studied using Wistar rats ( n = 10 per group). Two experiments were used: (I) stress with immobilization and water immersion at 22°C for 7 h plus the application of indomethacin (Indo) 10 mg/kg SC every 24 h for 3 days (comparator group), and (II) stress experiment I with the addition of 1 mL of Bioflora applied through a orogastric tube every 12 h for 3 days. At the 4th day, in asepsis, a dissection laparotomy of liver, spleen, mesenteric lymphatic nodes, and cecum was performed for microbiological culture, and stomach, ileum, and colon were also dissected for immunohistochemical and quantification of CD4+ and CD20. Findings in experiment I revealed cecum bacterial overdevelopment of 6 × 10 10 ± 2.3 × 10 9 colony-forming units (CFU) ( P
