Oxygen deprivation influences the survival of Listeria monocytogenes in gerbils.

ABSTRACT: Listeria monocytogenes is a facultative anaerobic foodborne pathogen capable of surviving harsh environments. Recent work has indicated that anaerobic conditions increase the resistance capability of certain strains to environmental stressors. The goal of the study was to conduct a preliminary study to determine whether exposure to anaerobic conditions prior to infection increases the ability to survive in vivo. Gerbils were inoculated with one of five doses of the L. monocytogenes strain F2365 by oral gavage: phosphate-buffered saline (control), 5 × 10⁶ colony forming units aerobic culture (low aerobic), 5 × 10⁸ aerobic culture (high aerobic), 5 × 10⁶ anaerobic culture (low anaerobic), or 5 × 10⁸ anaerobic culture (high anaerobic)
