Pseudoterranova decipiens larva is a rare cause of anisakiasis. Indeed, prior to the present study, there had been only 12 reports of larval P. decipiens infection in the Republic of Korea. In June 2011, an anisakid larva, 32.1 mm in length and 0.88 mm in width, and finally identified as the third stage larva of P. decipiens owing to the presence of an intestinal cecum but lacking ventricular appendage, was discovered in a 61-year-old woman during the course of endoscopy executed as a part of routine physical examinations. The patient had eaten raw a rockfish 13 hr prior to the endoscopy, but showed no symptoms of anisakiasis. This paper is the 13th report of P. decipiens infection in Korea.

We report a case of gastric pseudoterranoviasis proven by gastrofiberscopy on Dec. 13, 1994. The 34-year-old male patient, residing in Chungju-shi, was admitted to Konkuk University Hospital complaining of prickling epigastric pain. The symptoms suddenly attacked him two days after eating raw marine fish at Chonan-shi. By the gastrofiberscopic examination, a long white-yellowish nematode was found from the fundus region of stomach. The worm was $34.50{\;}{\times}{\;}0.84{\;}{\;}mm$ in size. and was identified as a 3rd stage larva of Pseudoterranova decipiens judging from the position of the intestinal cecum. This is the 12th confirmed case of human pseudoterranoviasis in Korea.

The results of study of the parasites of rockfishes, Sebastes spp. collected at Oregon coast aquarium during April 6 to June 30, 2002 are presented. Six species of parasites were recovered from examination of 19 rockfishes with an incidence of infection of 42.1 %. This study investigated parasitic infestation of 7 black rock-fish, Sebastes melanops ; 3 quillback rockfish, S. maliger ; 2 yellowtail rockfish, S. flavidus ; 3 canary rockfish, S. pinniger 2 yelloweye rockfish, S. ruberrimus ; 2 tiger rockfish, S. nigrocinctus. Sebastes spp. from aquarium were found to be infested with parasites: Mycrocotyle sebastis, Megalocotyle trituba, Clavella uncinata, Anisakis simplex larvae, Contracaecum sp. larvae, Pseudoterranova decipiens larvae. Prevalence and mean intensity of rockfishes were infected respectively as follows: 21.1%, 4.0 of M. sebastis, 10.5%, 55.5 of M. trituba, 21.1%, 34.3 of A. simplex larvae, 10.5%, 15.0 of Contracaecum sp. larvae, 10.5%, 8.5 of Pseudoterranova decipiens larvae and 10.5%, 5.0 of Clavella uncinata. This study reveled that gills and gastrointestinal tracts of S. pinniger were heavily infested with M. trituba and A. simplex larvae.

A case of Pseudoterranova decipiens infection was found in a 43-year-old man by gastroendoscopic examination on August 20, 1996. On August 6, 1996, he visited a local clinic, complaining of epigastric pain two days after eating raw marine fishes. Although the symptoms were relieved soon, endoscopic examination was done for differential diagnosis. A white, live nematode larva was removed from the fundus of the stomach. The larva was $38.3{\times}1.0{\;}mm$ in size and had a cecum reaching to the mid-level of the ventriculus. A lot of transverse striations were regularly arranged on the cuticle of its body surface, but the boring tooth and mucron were not observed at both ends of the worm. The worm was identified as the 4th stage larva of P. decipiens.

한국해양연구소의 극지연구센터가 운영되고 있는 남극 기지 부근 남극해에서 대구(Notoaenia neglecta)를 잡아 조사한 결과 위와 간에서 선충류 유충이 발견되었다. 광학현미경 및 전자현미경적 관찰 결과 이들은 인체에 codworm anisakiasis를 일으킬 수 있는 물개회충(Pseudotewunon decipiens)의 제3기 유충으로 동정되었다 유충의 길이는 25.0-28.5 m였고, 폭은 0.6-0.8 mm 였다. 주사전자현미경 소견상 충체 앞부분에서 boring tooth가 뚜렷이 관찰되었고, 3개의 입술과 배설공이 존재하였다. 충체 끝부분에는 작지만 뚜렷한 mucron 1개가 관찰되었다. 충체 단면의 광학현미경적 소견에서는 ventriculus의 전방 부위에서 특징적으로 ventriculus, intestinal caecum 및 Renette cell이 동시에 절단되어 있는 것이 관찰되었다. 이상의 결과를 통해 남극해산 대구가 물 개회충의 제3기 유충에 감염되어 있음을 확인할 수 있었으며, 남극해산 대구를 날로 먹을 경우 codworm anisakiasis를 유발할 수 있으므로 주의가 요망되었다.

1991년 4월 23일에 심한 상복부통을 주소로 부산 백병원 내과를 찾아온 42세 가정주부에 대한 내시경 검사에서 위벽을 뚫고 있는 아니사키스 유충 1마리를 검출하였다. 환자는 내원 약 15시간 전에 우럭 회를 먹은 경험이 있었으며 회를 먹고 약 6시간 후부터 심한 상복부통이 나타났다고 하였다. 각종 검사상 특이 소견은 없었고 위 내시경 검사에서 위체 대만부 중간부위의 점막을 뚫고 있는 아니사키스 유충 1마리를 발견하여 제거하였다. 제거한 충페는 $29.73{\;}{\times}{\;}0.94{\;}mm$ 크기이었고 ventriculus 전방 115 이상 부위까지 올라오는 맹장을 가지고 있었으며 ventricular appendage는 관찰되지 않았다. 충체의 전단에서 윤곽이 뚜렷한 3개의 구순은 관찰되었으나 boring tooth는 존재하지 않았고 후단에서 mucron도 관찰되지 않았다. 이상의 형태학적 특징 및 계측치를 토대로 하여 Pseudntewonon decipien (= Terranova type A) 제4기 유충인 것으로 동정하였다. 이 기생충의 국명을 물개회충으로 제안한다.

Along with globalization of traveling and trading, fish-borne nematodiases seems to be increasing in number. However, apart from occasional and sporadic case reports or mini-reviews of particular diseases in particular countries, an overview of fish-borne nematodiasis among travelers have never been performed. In this review, we gathered fish-borne nematodiasis among travelers for recent 25 years by an extensive global literature survey using appropriate keywords, e.g. travelers diseases, human infection, anisakiasis, gnathostomiasis, capillariasis, sushi, sashimi, ceviche, Gnathostoma, Pseudoterranova, Anisakis, Capillaria, etc., as well as various combinations of these key words. The Internet search engines PubMed, Medline, Google and Googler Scholar were used as much as possible, and the references of every paper were checked in order to identify useful and reliable publications. The results showed unexpectedly high incidence of gnathostomiasis and low incidence of anisakidosis. The different incidence values of the infection with several fish-borne zoonotic nematode species are discussed, as well as some epidemiological aspects of the infections. The difficulties of differential diagnosis in non-endemic countries are emphasized. It is concluded that travelers must avoid risky behaviors which can lead to infection and that physicians and health authorities must advice travelers on the risks of eating behaviors during travel.

We analyzed 320 clinical samples of parasitic infections submitted to the Department of Environmental Biology and Medical Parasitology, Hanyang University from January 2004 to June 2011. They consisted of 211 nematode infections, 64 trematode or cestode infections, 32 protozoan infections, and 13 infections with arthropods. The nematode infections included 67 cases of trichuriasis, 62 of anisakiasis (Anisakis sp. and Pseudoterranova decipiens), 40 of enterobiasis, and 24 of ascariasis, as well as other infections including strongyloidiasis, thelaziasis, loiasis, and hookworm infecions. Among the cestode or trematode infections, we observed 27 cases of diphyllobothriasis, 14 of sparganosis, 9 of clonorchiasis, and 5 of paragonimiasis together with a few cases of taeniasis saginata, cysticercosis cellulosae, hymenolepiasis, and echinostomiasis. The protozoan infections included 14 cases of malaria, 4 of cryptosporidiosis, and 3 of trichomoniasis, in addition to infections with Entamoeba histolytica, Entamoeba dispar, Entamoeba coli, Endolimax nana, Giardia lamblia, and Toxoplasma gondii. Among the arthropods, we detected 6 cases of Ixodes sp., 5 of Phthirus pubis, 1 of Sarcoptes scabiei, and 1 of fly larva. The results revealed that trichuriasis, anisakiasis, enterobiasis, and diphyllobothriasis were the most frequently found parasitosis among the clinical samples.
