Experimental infection with Ancylostoma caninum larvae in mice. IV. Serum protein pattern during primary infection.

Serum protein of Swiss albino mice infected with Ancylostoma caninum larvae, were analysed electrophoretically. Twenty mice were infected with a dose of 1000 larvae and the alterations in serum protein during an infection period of 30 days were recorded and compared with uninfected controls. The result showed a significant decrease in albumin and gamma globulin with an increase in beta globulin. There were no significant changes in the alpha-1 and alpha-2 globulins. The total globulins increased and A/G ratio decreased. These changes appeared to be remarkable on the 9th day after infection.
