Experimental infection with Ancylostoma caninum larvae in mice. V. Serum protein pattern during infection with various doses.

Serum protein patterns of Swiss albino mice during Ancylostoma caninum infection with varying dose levels were studied electrophoretically. There was a significant decrease in albumin associated with a corresponding increase in beta globulin in all the infected groups. Gamma globulin decreased significantly in all groups except the one infected with a challenge dose of 4000 larvae. Maximum changes occurred on day 31, 15, 9, 15 and 6 when mice were infected with 250, 500, 1000, 2000 and 4000 larvae, respectively. There was a significant negative correlation between albumin and the infective doses and a positive correlation between beta globulin and the infective doses and among the changes caused by different infective doses.
