SUMMARY Four lactating ewes infected by S. aureus -hemolytic and two controls were used to obtain serum, milk and mammary tissue samples. On blood and milk serum the levels of total proteins were determined by biuret reaction: their fractions were also determined by electrophoretic separation on celIulose acetate and polyacrilammide gel. Finally on homogenate mammary tissue were determined total protein level. In the acute phase of the infection an increase of serum proteins and a decrease of milk proteins were observed and they were correlated to protein fraction modifications and tissue damage.

Valutazione delle proteine totali e loro frazioni nel siero di sangue e latte e nel tessuto mammario in pecore infettate sperimentalmente.

Abstract

SUMMARY Four lactating ewes infected by S. aureus -hemolytic and two controls were used to obtain serum, milk and mammary tissue samples. On blood and milk serum the levels of total proteins were determined by biuret reaction: their fractions were also determined by electrophoretic separation on celIulose acetate and polyacrilammide gel. Finally on homogenate mammary tissue were determined total protein level. In the acute phase of the infection an increase of serum proteins and a decrease of milk proteins were observed and they were correlated to protein fraction modifications and tissue damage.
