【Abstract】 The laboratory mice of 7 strains,a total of 351 mice,wer examined for intestinal parasites.The laboratory mice of C₅₇BL/6,ICR,BALB/C,DBA/2, TA₁,TA₂,C₃H and 615 strains were bred in open system at our center.The age of mice was varied from the young to the old. The results showed that there were three species of intestinal protozoa: Trichomonas sp.,Giardia muris and Hexamita muris.The three species of intestinal helminths including pinworm and tapeworm were Syphacia obvelata,Aspiculuris letraptera and Hymenolepis nana. The positive rate of intestinal protozoa were Trichomonas sp.,100%,Giardia muris 49.57% and Hexamita muris 22.51%.The positive rates of intestinal hel- minths were Syphacia obvelata 58.40%,Aspiculuris tetraptera 21.94% and Hym- nolepis nana 21.37%.Among 7 strains of laboratory mice,the strain of the most severe infestation with Syphacia obvelata was C₅₇BL/6,C₃H strain for Aspiculuris tetraptera,ICR strain for Hymenolepis nana and Hexamita muris,TA₁ and C₃H strains for Giardia muris.更多还原
