Effect of temperature on the growth response of Salmonella enteritidis inoculated onto the vitelline membranes of fresh eggs.

摘要: The growth response of Salmonella Enteritidis (SE) on the vitelline membrane in vitro was studied with use a special tube devised specifically for inoculation SE onto and sampling yolk near site. This latter ability allowed detection movement into yolk. compared that inoculated albumen ovo fresh in-shell eggs. incubation time 2 days, temperatures were 4, 8, 15, 27, 37 degrees C. Comparison results obtained showed at 15 C, behaved as if it albumen, its numbers decreasing over time. At 27 grew yolk, maximum increase 4.5 log CFU after days In no experiments involving did appear Comparisons between responses indicate parallels egg.
