摘要:Chickens were fed different doses of lactobacillus suspension of L.casei.zhang ? MG2-1 and their fermented milk at age of 1 day ,and were vaccinated with ND(LaSota IV) at age of 7 days and 28 days.At age of 35 and 42days, and HI and serum antibody levels were determined .The results indicated that the antibody level of test groups were higher than the control group (p<0.05 or P<0.01), by 0.61to1.77(log2).Different strains and doses could influence the antibody level. L.casei.zhang ?MG2-1and their fermented milk all could improve immune responses in chickens.

摘要:To establish a rapid method to test Staphylococcus aureus, Vibrio parahaemolyticus and Listeria monogeneto in food,we designed three specific primmers according to SA ?LM and VP. The target gene was amplified from the three bacterium chromosomal DNA by using PCR technique. Electrophoresis of the products indicate there were three strips in 279bp?243bp and 202bp. Extraction the target strips sequence analysis indicated nucleotide sequences were consistent with the templates. The results revealed this method provided a specific,sensitive,and simple means for the three bacteria mentioned.

摘要:An aluminium-hydroxide absorbed inactived vaccine and oil adjuvant vaccine for infectious coryza were developed using local strains and vaccination experiments were conducted. After vaccination and challenged,chickens were considered protected if they did not show any signs of coryza clinically or at necropsy did not yield HPg on culture and showed specific HI antibody. The results indicated that the oil adjuvant coryza vaccine to be less protective than aluminium-hydroxide absorbed inactived vaccine for infectious coryza.
