| Abstract: | In this study,the clinical therapeutic effect of Chinese herbal compound composed of Euphorbia humifusa Willd.and Punica granatum L.on ducklings infected with Escherichia coli (E.coli) was studied in order to provide a new therapeutic method for clinical treatment of E.coli.Fifty healthy one-day-old ducklings were selected and randomly divided into five groups,ten ducklings in each group.The experimental groups were blank control group,model group,amoxicillin group,Chinese medicine compound high-dose group(DSH) and low-dose group(DSL).The administration group started administration at 3 days of age,continued administration for 3 days,and continued administration until the end of the experiment,10 days total.Except for control group,when the ducklings were 6 days old,E. coli was intraperitoneally injected for challenge,0.5 mL/head.The mortality of the experimental groups was compared.The dead ducks and the surviving ducks were dissected,the pathological section of liver and small intestine and HE staining sections were observed.The blood routine indexes and serum biochemical analysis were detected to evaluate the therapeutic effect of traditional Chinese medicine compound on E.coli infected ducklings.The results showed that the high and low doses of the traditional Chinese medicine compound and the amoxicillin could effectively reduce the mortality of infected ducklings.Compared with model group,amoxicillin and traditional Chinese medicine high and low dose groups could reduce liver,small intestine and other organs damage.Compared with control group,aspartate aminotransferase (AST) and alanine aminotransferase (ALT) in model group increased significantly (P<0.05),and alkaline phosphatase (ALP),lactate dehydrogenase (LDH),UREA also showed extremely significant upward trend (P<0.01),and the WBC,RBC,HGB,PLT and other indicators changed extremely significantly(P<0.05).Compared with model group,the alkaline phosphatase(ALP)value was significantly or extremely decreased in the administration group(P<0.05;P<0.01),and the blood WBC,RBC,HGB and PLT indexes were extremely significantly increased (P<0.01).The results indicated that the degree of body damage in the administration group was lower than that in the model group. |
