[Influence of the migration of Ascaris suum larvae on blood parameters in the pig]

Biochemical and hematological blood parameters were investigated in pigs experimentally infected with Ascaris suum. The most marked changes were recorded on day 5-8 post inoculation, during fever. In this period there was a marked decrease of concentrations of albumin, iron, thyroxin, A and E vitamins in blood serum, while compared with the control group the contents of A vitamin in liver did not change. Further, the concentrations of nonesterified fatty acid increased, as well as those of inorganic phosphorus and 11-hydroxycorticosteroids. Till day 13 PI the decrease of albumin and iron concentrations intensified and a recession of cholesterol serum binding capacity for iron was also recorded. Our results suggest that the acute phase of pig ascariasis is accompanied by changes in the host metabolism, generally corresponding to findings in fever states of different aetiology.
