Enterococcus cecorum lesion strains are less sensitive to the hostile environment of albumen and more resistant to lysozyme compared to cloaca strains

Avian Pathol. 2024 Apr;53(2):106-114. doi: 10.1080/03079457.2023.2286985. Epub 2024 Jan 25.

Abstract

Egg albumen inhibits Enterococcus cecorum cloaca strains more than lesion strains.Enterococcus cecorum lesion strains are resistant to high concentrations of lysozyme.Lysozyme resistance could enhance survival in albumen and body fluids.

Keywords: Enterococcus cecorum; albumen; biotyping; embryo lethality assay; hen egg white; lysozyme; virulence.
