Using Candida oleophila as a biocontriol agens to prevent foodborne Escherichia coli O157 EHEC infections.

Wang Y, Wei A, Li H - Springerplus (2012)

Bottom Line: Escherichia coli O157:H7 (EHEC O157) is a serious pathogen causing haemorrhagic colitis.The results presented in this study indicated that EHEC O157 could survive and grow in wounded 'Fuji' apples and extensively proliferate.Water as a decontaminant was ineffective in reducing EHEC O157 in wounded apples.

ABSTRACT
Escherichia coli O157:H7 (EHEC O157) is a serious pathogen causing haemorrhagic colitis. In this study, inactivation kinetics of inoculated EHEC O157 and response of EHEC O157 in apple wounds by different concentrations of C. oleophila was investigated. The results presented in this study indicated that EHEC O157 could survive and grow in wounded 'Fuji' apples and extensively proliferate. Water as a decontaminant was ineffective in reducing EHEC O157 in wounded apples. C. oleophila could be a viable method of controlling wound contaminated by this pathogen at room temperature.

Fig3: Concentration dynamics ofC. oleophiladuring storage at 25°C with EHEC O157.

Mentions: The C. oleophila populations inoculated with EHEC O157 increased evidently to maximum populations during the first 2 days following its application to wounded apples with little changes thereafter. The result was presented in Figure 3. Mean maximum populations of C. oleophila recovered from apples did not differ significantly each other regardless of initial inoculum concentrations.Figure 3
