ABSTRACT
Human cases of echinostomiasis have been sporadically diagnosed by extracting worms in the endoscopy in Korea and Japan. Most of these were caused by Echinostoma hortense infection. However, in the present study, we detected 2 live worms of Echinostoma cinetorchis in the ascending colon of a Korean man (68-year old) admitted to the Gyeongsang National University Hospital with complaint of intermittent right lower quadrant abdominal pain for 5 days. Under colonoscopy, 1 worm was found attached on the edematous and hyperemic mucosal surface of the proximal ascending colon and the other was detected on the mid-ascending colon. Both worms were removed from the mucosal surface with a grasping forceps, and morphologically identified as E. cinetorchis by the characteristic head crown with total 37 collar spines including 5 end-group ones on both sides, disappearance of testes, and eggs of 108x60 microm with abopercular wrinkles. The infection source of this case seems to be the raw frogs eaten 2 months ago. This is the first case of endoscopy-diagnosed E. cinetorchis infection in Korea.

Se realizo un estudio coprológico por la técnica de flotación Mc Master (Willis-Molloy), realizando contaje de Huevos por gramo de Heces (HPG), a 100 equinos Pura Sangre de Carreras, durante el periodo de cuarentena Hipodromo La Rinconada Caracas Venezuela. Se procedió a la desparasitacióncon una terapéutica a base de Febantel, dosis 6mg/kg, presentación en pasta, vía oral (CALOXBANTEL) Febantel 88.7 mg; Excipientes c.s.p. 1g. A los 7 días post-desparasitación se realizo un estudio coprológico por la técnica de flotación Mc Master (Willis-Molloy), realizando contaje de Huevos por gramo de Heces (HPG). El estudio coprológico evidencio un 60% de infestación (60/100) en los caballos estudiados. El 40% (40/100) fue negativo al examen coprológico. Los resultados post-tratamientos fueron 1% de infestación persistente (01/100) y un 99% (99/100) negativos al examen coprológico. En todos los casos la infestación parasitaria fue por Strongylus sp. La presencia de Strongylus sp. se mantuvo por equino infestado entre un rango de 400-1200 HPG
We study 100 Thoroughbred horses, in the Racetrack La Rinconada Caracas, Venezuela, by McMaster flotation technique (Willis-Molloy), making counting of eggs per gram of feces (EPG) before deworming, each of the copies, then proceeded to the parasite with a Febantel based therapy, dose 6mg/kg, pasta presentation, oral (CALOXBANTEL) Febantel 88.7 mg, Excipients 1g. At 7 days post-parasite stool study was conducted by the McMaster flotation technique (Willis- Molloy), by counting eggs per gram of faeces (EPG). The coprology study showed 60% infestation (60/100) in horses studied. The 40% (40/100) was negative. The post-treatment were 1% infestation (01/100) and 99% (99/100) was negative. In all cases, parasite infestation was by Strongylus sp. within the range of 400-1200 HPG

As gastroduodenoscopy performed more frequently, case reports of human echinostomiasis are increasing in Korea. A Korean woman presented at a local clinic with complaints of abdominal pain and discomfort that had persisted for 2 weeks. Under gastroduodenoscopy, two motile flukes were found attached on the duodenal bulb, and retrieved with endoscopic forceps. She had history of eating raw frog meat. The two flukes were identified as Echinostoma hortense by egg morphology, 27 collar spines with 4 end-group spines, and surface ultrastructural characters. This report may prove frogs to be a source of human echinostome infections.

A human Echinostoma hortense infection was diagnosed by gastroduodenoscopy. An 81-year-old Korean male, living in Yeongcheon-shi, Gyeongsangbuk-do and with epigastric discomfort of several days duration, was subjected to upper gastrointestinal endoscopy. He was in the habit of eating fresh water fish. Two live worms were found in the duodenal bulb area and were removed using an endoscopic forcep. Based on their morphological characteristics, the worms were identified as E. hortense. The patient was treated with praziquantel 10 mg/kg as a single dose. The source of the infection in this case remains unclear, but the fresh water fish consumed, including the loach, may have been the source. This is the second case of E. hortense infection diagnosed by endoscopy in Korea.
