RESUMEN
We report here a human case probably mixed-infected with Clonorchis sinensis and Fasciola sp. who was diagnosed by computed tomography (CT) scan, serological findings, and/or fecal examination. The patient was a 43-year-old Korean female and was admitted to Kyung Hee University Hospital with the complaints of fever and abdominal pain. On admission, marked eosinophilia was noted in her peripheral blood. CT scan showed specific lesions for clonorchiasis and fascioliasis in the liver, along with lesions suggestive of amebic abscess. Micro-ELISA revealed positive results for the 2 helminthic infections. Eggs of C. sinensis and trophozoites of Entamoeba histolytica were observed in the stool. Treatment with praziquantel followed by metronidazole and tinidazole reduced abnormalities in the liver and eosinophilia. This is the first case report of a possible co-infection with 2 kinds of liver flukes in the Republic of Korea.
RESUMEN
Fasciola eggs were collected from stool of a woman aged 21 years old in Nghe An province. Miracidium were obtained from these eggs after 20 days culture in the laboratory. A portion of the mitochondrial-encoded nad1 gene from these miracidiums were amplified using polymerase chain reaction (PCR) and comparatively aligned with the known corresponding sequences of Fasciola gigantica taken from cattle in Hoa Binh, Lai Chau, Lang Son, Ninh Binh and international strains (from Korea, Japan and Indonesia). The results showed high similar co-efficient of nucleotide 98-99% and amino acid 95-99%, but lower rate than that of Fasciola hepatica (Australian and American) (90-92%). However, it is suggested that the Vietnamese F.gigantica have had the genetic signs hybridized with F.hepatica
