Study the Effectiveness of Chitosan on Experimental Infection of Chicks with Salmonellosis


Abstract: This research attributed with chitosan as prebiotic and immunomodulator as well as to determine its effect on the body weights of experimental of chicks. The results had been showed increasing in body weights of chicks had been given chitosan. The bacterial isolated revealed that chicks groups exposed to infection with Salmonella typhimurium and treated with chitosan before and with the same time of infection, these groups appeared a decrease in the bacterial isolation from intestines and liver in comparing with those exposed to infection without given chitosan The passive heamagglutination test also revealed higher antibodies titers against Salmonella typhimurium in the same groups above in comparing with positive and negative control groups, so all these results detected the ability of this compound as inhibitor for bacterial growth and replication and to minimize their numbers as well as its effect and immunomodullator.
