Cyclosporiasis – France ex Mexico

This case of cyclospora may have no relation to the Canadian outbreak; or may.

A 64-year-old French [female] with type 2 diabetes mellitus was referred to our department on [Mon 3 Jul 2017] because she was suffering from protracted diarrhea.

Symptoms began on [Sat 10 Jun 2017] as she was just returning from a touristic trip in Cancun (Quintana Roo State, Mexico) where she stayed from [Mon 29 May to Fri 9 Jun 2017] with her husband.

She acknowledged having moderate watery diarrhea with abdominal discomfort, bloating, transient vomiting, 5 kg weight [approx. 11.02 pounds] loss and fatigue. Empiric therapy with oral Metronidazole 500 mg 3 times a day for 7 days she received previously failed to improve her symptoms. Of note, a 1st microscopic stool examination failed to identify parasites and no enteropathogenic bacteria was found by culture on selective media.

Up to 3 extra stool specimens where sent to the laboratory of clinical parasitology in our hospital.

Oocysts of Cyclospora cayetanensis where evidenced by autofluorescence after Bailenger concentration technique.
