Abstract

A study was undertaken to investigate the effect of Salmonella gallinarum endotoxin on clinical symptoms and some haematological changes in mature six-month-old cockerels. Salmonella gallinarum endotoxin caused characteristic clinical symptoms, severe olygocytic hypochromic anaemia, leucocytosis and increased phagocytic function of leucocytes. Heterophilia was associated with relative lyphopenia. The endotoxin manifested pyrogenic activity. The demonstrated signs were similar to those produced in chickens with experimental fowl typhoid. Together, these features suggest that Salmonella gallinarum endotoxin has been a contributor to the main manifestation of experimental fowl typhoid in birds.
