Dynamic variation of eosinophil count in rabbits infected with Trichinella Spiralis

Objective To observe the dynamic change of eosinophil count in rabbits infected with Trichinella spiralis so as to offer basic data for eosinophil examination in trichinosis.Methods Experimental rabbits were divided into two groups each consisted of 10 rabits.The rabbits in infected group were inoculated by gavage with 10 000 Trichinella spiralis larvae,10 rabbits in control group.The blood samples were obtained from rabbits in the two group at different time after infection,the eosinophil absolute count was determined.Results The eosinophil absolute count in infected group raised and reached peak on the fourth week after infection and then began to decline therafter.Conclusions The detection of eosinophil examination has assistant values in diagnosis of trichinosis.
