A corollary of this observation is that the STs that have caused outbreaks of human infections

in other parts of the world have the potential to cause outbreaks in China. However, there is hardly any data on human L. monocytogenes infections in China partly due to the lack of clinical listeriosis surveillance. A recent GSK1120212 purchase report of 6 cases of neonatal listeriosis in a Beijing hospital of 13,372 live births in 2008 highlights that the disease may be more common in China [35]. With the country becoming more effluent, food distribution, storage and consumption patterns have also changed. Since the isolates from food sources as shown in this study clearly have the potential to cause disease, there is a need for surveillance of clinical listeriosis and Capmatinib datasheet implementation of prevention strategies to prevent emergence and outbreaks of human L. monocytogenes infections in China. The findings also have implications for other countries where there is no surveillance system for L. monocytogenes . Acknowledgments
