| Popis: | In recent years many researchers have described the reduced mycotoxin toxicity caused by probiotic bacteria. Since reduction under gastrointestinal conditions of the bioavailability of mycotoxins by probiotics is not fully investigated in birds, the aim of the study was to determine the effect of probiotic on T-2 mycotoxicosis induced apoptosis in broiler’s liver. For the study, twelve 1-days old broilers were divided equally into T-2 toxin (T2) and probiotic with T-2 (P+T2) groups. From the first experimental day, probiotic Enterococcus faecium DSM 7134 was administered in drinking water to P+T2 group. From the fourth day, T-2 toxin was given for three consecutive days to T2 toxin group. At 8th experimental day chicken were sacrificed, liver was fixed in buffered 10% formalin, embedded into paraffin, slices 5 μm in thickness were cut followed by immunohistochemical staining with polyclonal primary antibodies p21 and p53 (Abcam, UK) according to the manufacturers’ guidelines (IHC kit, Abcam, UK). Blood samples were taken by cardiac puncture to measure liver enzymes. Immunohistochemical staining revealed strong expression of p53 and p21 antibodies in hepatocytes nuclei as well as around blood vessels in T-2 toxin group’s chicken liver tissue. Staining by both antibodies was less intensive in P+T2 group. Enzyme analysis showed significantly increased (p |
