[Influence of Ascaridia-galli invasion on amino acid, protein and aminotransferase (GOP, GTP) levels and activities in chickens].

A negative influence of the helminths Ascaridia galli on the level of free plasma amino acids and aspartate and alanine aminotransferase activities was demonstrated in the host chick serum. Despite the above negative influence single experimental Ascaridia galli invasion failed to influence the serum protein level or weight increments in chicks. At low invasion intensity the experimental chicks were able to compensate for the pathogenic effect of the helminth Ascaridia galli, manifested by decreased amino acid and aminotransferase activity levels, provided that they were given a full-value and the chicks were kept under suitable zoohygienical conditions.
