Multilocus Sequence Typing Tool for Cyclospora cayetanensis

Cyclospora cayetanensis is an emerging parasitic pathogen responsible for numerous foodborne outbreaks of cyclosporiasis in North America, primarily associated with imported fresh produce from cyclosporiasis-endemic areas (1). The lack of genotyping tools has hampered case linkage and infection/contamination source tracking (2). In this study, we developed a multilocus sequence typing (MLST) tool to help with identification of this protozoan.
