Cadmium is a wide-spread heavy metal that causes a wide range of health problems in animals and humans. Many reports showed the biosorption of heavy metals by bacteria. The objectives of this study were to evaluate the potency of probiotics bacteria of Lactobacillus plantarum and Bacillus coagulans against cadmium adsorption in rats. Twenty four male adult Wistar rats were randomly divided into six groups. Cadmium treated groups received 1 ml of 100 µg/ml CdCl2 and probiotics groups were administrated 1 ml of (109 CFU/ml) of probiotics during 24 days by special gavage needle once daily. Levels of cadmium were determined by using graphite furnace atomic absorption spectrometry. Probiotics B. coagulans and L. plantarum caused 29.8% and 19.3% increasing in removal of cadmium through defecation and decreased 10.9 and 21.5 % of cadmium accumulation in kidney of Wistar rats. The results showed that oral administration of both probiotics offered a significant protective effect against cadmium adsorption in rats.
