The influence of temperature on the behaviour of mixed bacterial contamination of the shell membrane of the hen's egg.
The inner membrane of the air cell of hens' eggs was inoculated with Pseudomonas putida, Staphylococcus xylosus, Enterococcus faecalis, Escherichia coli and Salmonella enteritidis. The first mentioned eventually dominated the contamination of the albumen of eggs stored at 4, 15, and 20 degrees C. The last mentioned did so in eggs stored at 37 degrees C. The interval between inoculation of the membrane and gross contamination of the albumen was markedly influenced by site of contamination relative to yolk movement.
