In order to study the anti-infection effect of phoshporylated Agaricus blazei polysaccharide on mice, mice were drenched phoshporylated A. blazei polysaccharide for 14 d, and an A. blazei polysaccharide control group and a blank control group were also set. The mice in all the three groups were infected with Escherichia coli on the 15 th day and the 29 th day of the experiment, the body weight of the mice in each group was recorded, as well as the spleen index on the 29 th day of infection and the 36 th day of the experiment, and the anti- E. coli titer in serum was also detected. The results showed that phoshporylated A. blazei polysaccharide could promote and maintain the development of spleen, and improve the immune response of organisms, thereby resisting bacterial infection. Furthermore, phoshporylated A. blazei polysaccharide has better immunoregulation and anti-infection effects than A. blazei polysaccharide, and could play an important role in veterinary clinical treatment and prevention and control of diseases as a immunologic adjuvant or immunopotentiator. 展开更多

The yields of successive generations were increased more than 70% to compare with their original strain. The component analysis on amino acids and fatty acid illuminated that the nutrient value of strain J3 fruiting body was better than the original strain. The apparent nodule structure was found in the hyphea of J3 strain through the observation by scanning electron microscope. RAPD analysis showed the great difference of PCR fingerprints between J3 and its original strain. It is a promising mutant strain for further commercial development in the future. 展开更多

In order to study the anti-bacterial infection effect of polysaccharide from Agaricus blazei Murrill on chickens, the experimental groups were orally administrated A. blazei polysaccharide at low dose and high dose, respectively, for 14 d continuously, and then, the chickens in various groups were infected with Escherichia coli or Pasteurella pneumotropica , so as to observe the clinical symptoms of chickens and record the change in body weight. Anatomy was performed 14 d later, and the organ indices were determined, so as to study the anti-bacterial infection effect of A. blazei polysaccharide on chickens. The results showed that after bacterial infection, the high-dose A. blazei polysaccharide group was significantly differed from other groups in changes of body weight and organ indices. It indicates that oral administration of high concentration of A. blazei polysaccharide could promote the development of poultry organs, thereby improving the immunity of organisms. 展开更多

To explore the mechanism of Agaricus blazei Murrill enrichment of the heavy metal cadmium,we employed Illumina high-throughput sequencing to analyze the transcriptomes of A.blazei mycelia treated with and without exogenous cadmium addition,and then the differentially expressed genes(DEGs)of the strains with high and low cadmium enrichment between the control and cadmium treatment were screened out.The results showed that the DEGs were mainly involved in steroid biosynthesis,antibiotic biosynthesis,protein processing in endoplasmic reticulum,glutathione metabolism and other pathways.Carbon metabolism and glutathione metabolism may play an important role in the response of A.blazei mycelium to cadmium stress. 展开更多
