Which clinical sign may be observed in chickens infected with Salmonella enteritidis?

Explanation:
Salmonella enteritidis in chickens often causes a systemic, disseminated infection, so the most characteristic clinical finding is septicemia with involvement of the reticuloendothelial organs. When the bacteria spread through the bloodstream, the liver and spleen become enlarged due to inflammation and bacterial load, leading to hepatomegaly and splenomegaly. This septicemic state may be accompanied by polyserositis, but the direct, observable sign you’d expect to see in affected birds is septicemia with enlarged liver and spleen. Pneumonia and dermatitis are not typical primary manifestations of Salmonella enteritidis in chickens.
