The aim of the present study was to investigate the antigenotoxic properties of the probiotic Lactobacillus rhamnosus IMC501; DNA damage was induced by one representative food mutagen, 2-amino-1-methyl-6-phenylimidazo[4,5-b]pyridine (PhIP). Mice were treated orally with suspensions of lactobacilli for 10 days before administration of food mutagen. During the treatment, the abundance of lactobac...

Based on the internal study results there has been examined effect of three feed additives different functional status (butyric acid, organomineral chelate compounds, lycopene) occurrence micronuclei (MN) and other nuclear anomalies (NA) in Danio rerio erythrocytes. Evaluation genotoxicity butyric acid didn’t show any genotoxic throughout experiment. The highest frequency MN was recorded 5th da...

Patulin (PAT) is a mycotoxin produced by certain species of Penicillium, Aspergillus, and Byssochlamys. Previous studies demonstrated its cytotoxic, genotoxic, and mutagenic effects in different cell lines. However, there is little information available concerning its toxic behavior in vivo. In the present study, we investigated PAT-induced hepatotoxicity and genotoxicity in mice. We also inves...

Aflatoxin B(1) is a contaminant of agricultural and dairy products that can be related to mutagenic and carcinogenic effects. In this report we explore the capacity of alpha-mannan (Man) to reduce the DNA damage induced by AFB(1) in mouse hepatocytes. For this purpose we applied the comet assay to groups of animals which were first administered Man (100, 400 and 700 mg/kg, respectively) and 20 ...
