Toxigenicity of culture filtrates of Salmonella enteritidis isolates on three mammalian cell lines.
Culture filtrates of 28 Salmonella enteritidis isolates were tested for toxicity on Vero-, CHO-, and human foreskin fibroblast (HFF) cells. Cytopathic effects on HFF cells were extensive, and were observed even with some filtrates diluted 1:256. Vero cells showed effects with filtrates diluted up to 1:16, and CHO cells gave weak or no reaction. All isolates produced iron-binding siderophores as determined by reactions on chrome-azurol-S medium.
