[Penetration of Staphylococci through the egg-shell].

Penetration of staphylococci through egg-shell structures into the egg content was studied in 490 eggs. A series of experiments proved that staphylococci were able to penetrate through all egg-shell structures in a short time (of 1 hour) after the contamination. According to the results of these experiments, penetration was affected by the presence of cuticle, different shell porosity and high pH of the egg white.
