A Case Report of Diarrhea Associated with Giardia lambria and Salmonella

Abstract

We report a case of diarrhea associated with Giardia lambria and Salmonella. A 28-year-old male who had no chance to go abroad visited our hospital with complaints of abdominal pain, watery diarrhea and fever, but his symptoms persisted in spite of medication. He was admitted to our hospital on the next day for definite diagnosis and treatment. Many trophozoites of Giardia lambria were recognized in the feces. The symptoms were improved using metronidazole, so he was discharged on the 8-th day. The cause of this double infection was not determined. The domestic infection like this case is rare in Japan.
