New Options for Rapid Typing of Salmonella enterica Serovars for Outbreak Investigation

A number of different serovars of Salmonella enterica are often implicated in human nontyphoidal outbreaks. Globally, serovars Typhimurium and Enteritidis are often the causative agent of such outbreaks, but other serovars can also be significant (Table 1). Some serovars such as Infantis and Virchow are routinely linked to outbreaks of gastroenteritis. The consumption of raw food products or poor food handling practices and/or storage procedures is often a catalyst for such outbreaks (Behravesh et al., 2010).
