Tropheryma whipplei , Helicobacter pylori , and Intestinal Protozoal Co-Infections in Italian and Immigrant Populations: A Cross-Sectional Study.

The present study is the first to report a high TW and HP co-infection rate. To reduce the risk of morbidity from a chronic infection of either pathogen, clinicians may consider TW-HP molecular screening on the same stool sample for patients with suspected HP disease or WD, particularly in case of travel history.
