Effect of probiotics on hematology and histopathology of organs associated with immune system in male and female Wistar rats

Abstract

In the present study, potential probiotics were isolated from dairy products and characterized on a molecular basis. Male and female (16 + 16, n = 4) Wistar rats were randomly assigned to 5 groups to revise the effects of isolated potential probiotics on the gut immune system: 0-day, negative control, positive control (commercial product Lactobacillus acidophilus-14), laboratory isolated strains Pro-3 (Weissella confusa MZ735961), and Pro-4 (Lactiplantibacillus plantarum MZ727611). Aspartate-aminotransferase, Interleukin-6, bilirubin, and Alanine-transaminase values in both genders were expected but AST and creatinine values had a minor increase in the female group compared to the male probiotic-treated group. Cellular blood count level of mean corpuscular hemoglobin in male groups showed no considerable differences (p = 0.95), while there were decreased differences (p = 0.00) in female groups. The level of mean corpuscular hemoglobin concentration (MCHC) showed distinct variations (p = 0.02) in male groups, while these values were insignificant changes (p > 0.05) among female groups. No damage to the liver, thymus, or colon was ascertained based on morphological findings. The colon wall thickness, external muscle, crypt depth, and mucosa were significantly (p = 0.03) improved in rats given potential probiotics. In conclusion, probiotic supplementation stimulates the immune system. It may protect the intestinal mucosa by strengthening the gut’s immune system and promoting intestinal efficiency (nutrient absorption and number of goblet cells). L. plantarum can therefore offer a reliable, affordable, and safe treatment for functional gastrointestinal illnesses.
