WAYNE, Pa.--(BUSINESS WIRE)--Molecular strain typing has become an essential tool for the analysis of bacterial pathogens obtained during investigations of epidemiologic outbreaks, laboratory contamination, and recurrent infection. Similarly, the results of bacterial strain typing are now used in many different contexts, including clinical care settings; public health investigations, particularly of emerging infections; the food and pharmaceutical industries; and environmental analyses. A wide variety of strain typing methods have been described using contemporary DNA-based technologies. However, developing methods and generating data have proven easier than defining robust approaches for interpreting the results.
