Co-infection with Cyclospora cayetanensis and Salmonella typhi in a patient with HIV infection and chronic diarrhoea

A 45-year-old-Haitian male patient with fever, abdominal cramping, chronic diarrhoea and weight loss of about 3 kg was investigated. Stool examination revealed Salmonella typhi and Cyclospora cayetanensis. The HIV test was positive with a CD4 count of 130 cells/mm3. We provided the first report of co-infection Cyclospora cayetanensis and Salmonella typhi in a HIV patient with chronic diarrhoea. The patient was treated with oral ciprofloxacin, 500 mg, twice daily for two weeks, with a good clinical outcome.
