Effect of egg storage upon the survival of Campylobacter jejuni in laboratory-infected fertile poultry eggs.
Fertile eggs were infected by Campylobacter jejuni in the laboratory by a temperature differential method of inoculation, which resulted in up to 10% of the hatched birds carrying C. jejuni in the intestine. When infected eggs were stored for 5 1/2 days before incubation, the infection rate of the eggs had decreased to 20% or less when set, and no infected chicks were hatched. Inoculation of eggs after 8 days in storage also failed to yield infected chicks. In all cases, the hatch ratio was no different from that of uninfected control eggs.
