Authors experienced a case of human infection with Anisakis sp. in left tonsil. The case was 27 year Korean female who visited Department of Otolaryngology, Severance Hospital with the chief complaints of swollowing difficulty, and the sensation of a foreign body in the throat, on November 20th 1968. Physical examination of the oral cavity revealed that both palatin tonsil were chronically enlarged. A larval worm was found in crypt of the upper portion of the left palatin tonsil. Chief complaints of the patient was improved after removal of it by forceps. The greyish white living worm was fixed in lactophenol solution for morphological study. The worm measured 36 mm in length by 0.6 mm in width, 2.4 mm in esophageal length, 1.4 mm in ventricule, 0.1 mm in tail length, and 0.025 mm in caudal spine length, respectively and histological study was carried out from the serial section of the larva which was stained with hematoxylin eosin. Authors identified that the larva was Anisakis species.

The Korean Journal of Parasitology.1971;9(1):25-38. doi:10.3347/kjp.1971.9.1.25

A survey of intestinal parasites infection among Korean people has been carried out during July 1969 to December 1970. A total of 2,250 stool specimens (male 1,101, female 1,146) was collected from all the provinces and Seoul city in Korea. The specimens were examined routinely by direct fecal smear, zinc sulfate flotation and formalin-ether sedimentation techniques. The results are summarized as follows: Of 2,250 specimens examined, l,803(80.l per cent) were positive for intestinal parasites. The positive rates of intestinal helminths were 1,644(73.1 per cent) among 2,250; Ascaris lumbricoides 46.0 per cent, Trichocephalus trichiurus 46.8 percent, hookworm 6.8 per cent, Trichostrongylus orientalis 7.0 percent, Clonorchis sinensis 12.1 percent, Enterobius vermicularis 1.6 per cent, Hymenolepis nana 0.7 percent, Taenia species 0.3 per cent, Metagonimus yokogawai 0.04 percent, Fasciolidae 0.04 per cent and one case of lung fluke Paragonimu westermani. The positive rstes of intestinal protozoa were 786(34.9 per cent); Entamoeba histolytica 6.4 per cent, Entamoeba coli 20.5 percent, Endolimax nana 10.0 per cent, Giardia lamblia 5.1 per cent, Trichomonas hominis 1.1 percent, Chilomastix mesnili 0.5 percent, Iodamoeba butschlii 0.6 percent, Enteromonas hominis 0.7 percent, Dientamoeba fragilis 0.1 per cent and one case of Isospora hominis. Sexual distribution of helminths and protozoan infections showed higher rate in female than that of male, except C. sinensis, H. nana, Taenia species or G. lamblia Infections of T. trichiurus, hookworm, T. orientalis, C. sinensis, Taenia species, E. histolytica, E. coli and E. nana increased with age. Conversely, H. nana and G. lamblia infections were more predominent in younger ages.

Jong Phil CHU

The Korean Journal of Parasitology.1984;22(1):85-95. doi:10.3347/kjp.1984.22.1.85

This study was performed to investigate the intestinal parasites (especially cestoda) in the guts of Theragra chalcogramma in Korea. The cestode larvae collected were morphologically observed and measured, and at the same time, microscopical study was done with the section slides of the cestode larvae. They were identified on the basis of the descriptions by Schmidt and Yamaguti. The results obtained in this study are as follows: The cestode larvae were identified as Khawia sinesis, Eulacistorhynchus chiloscyllius, Tentacularia coryphaenea, Pseudonybelinia odontacantha and Nybelinia lingualis. These are new species reported in Korea. The characteristics of Khawia sinesis are its scolex lacking loculi and broad, flat and fimbriate shape. Its neck is not separated from the body but a little constricted. Eulacistorhynchus chiloscyllius is characterized by fairly long and acraspedote scolex. The bulbs are long; retractor muscles are attached to bases of the bulbs. The two bothridia are oval or round in shape and lacking posterior notch. The tentacles are long and poeciloacanthus; double chainette present. Tentacularia coryphaenea is characterized by its long craspedote and subcylindrical scolex. The bothridia are separated, without free borders and spinous. The tentacles are short, slender, armed with solid hooks in spirals, similar except the base of tentacle. The tentacle sheaths are not twisted. The bulbs are ellipsoidal. Pseudonybelinia odontacantha is characterized by its craspedote scolex. The tentacles are inserted near anterior margin of bothridia and armed with hooks in spirals ascending left to right. The hooks are similar, throughout tentacle, with feeble curve and provided with a tooth-like protuberance on the ventral side. The bulbs are three times longer than its width. The posterior margins of bothridia have a pair of eversible ciliated pits; or fossettes. Nybelinia lingualis is characterized by its short and craspedote scolex. The bothridia are separated, with free boarders. The tentacles are cylindrical, armed with solid and similar hooks in quincunxes.

Infestation of larval trematodes from fresh-water fish and brackish-water fish in River Hyungsan, Kyungpook Province, Korea.

Chong Yoon JOO

The Korean Journal of Parasitology.1984;22(1):78-84. doi:10.3347/kjp.1984.22.1.78

In order to determine the infestation patterns for metacercaria of digenetic trematodes, several kinds of fresh-water and brackish-water fish were caught in River Hyungsan, Kyungpook Province, Korea and examined from March to October in 1983. They were collected by netting, fishig with rod and line, or using the bait of crushed oil cake in transparent plastic bowls, and were dissected into the flesh, scales and fins with tail, and then examined for the presence and infestation density of larval trematodes. Of the 11 kinds of fish examined, the encysted larvae of Exorchis oviformis were found all of them, Metagonimus yokogawai from 9 kinds, Cyathocotyle orientalis, Metacercaria hasegawai and Metorchis orientalis from 6 kinds, and Clonorchis sinensis from 4 kinds in the present study. In the intensity of infestation with Clonorchis sinensis, the Korean shiner, Gnathopogon atromaculatus Nichols et Pope, was the most heavily infected species, the average number of metacercariae per gram of fish flesh being 45.5, followed by the striped shiner, Puntungia herzi Herzenstein 11.6, and Southern top-mouthed minnow, Pseudorasbora parva (Temminck et Shlegel), 9.7. The intensity of infestation with the Metagonimus larvae in 8 species of fresh-water fish was relatively low, and the average number per gram of flesh varied from 0.23 to 9.1. In comparison, the brackish-water fish were more heavily infected and the mean number of cysts per gram of flesh in the sweetfish, Plecoglossus altivelis, was 32.9. The results of this study generally indicate that Clonorchis sinensis and Metagonimus yokogawai infection may occur by consuming raw fresh-water fish caught in the river Hyungsan, Kyungpook Province, Korea.

The Korean Journal of Parasitology.1984;22(1):72-77. doi:10.3347/kjp.1984.22.1.72

A case of congenital malaria infection has been studied in a 46-day old female Korean infant. Her mother suffered from malaria infection during pregnancy in Uppervolta, Africa, and returned to Korea at the 9th month of gestation for delivery. At 39 days of age, the clinical features characterized by fever, irritability, pallor, jaundice and hepatosplenomegaly were developed. The laboratory data revealed a hemolytic anemia with thrombocytopenia, hyperbilirubinemia and increased hepatic enzyme values. A peripheral blood smear demonstrated intraerythrocytic malarial parasites snd gametocytes of Plasmodium falcifarum. She was successfully treated with quinine sulfate (25 mg/kg/day in three doses for 5 days) and trimethoprim/sulfamethoxazole (8 mg/kg/day in two doses for 5 days) orally, and repeated blood smear had been negative for malaria. This report also signifies the frst description of congenital malaria in Korea imported from Uppervolta in Africa. A brief review of related literature was made.

The Korean Journal of Parasitology.1984;22(1):66-71. doi:10.3347/kjp.1984.22.1.66

Two cases of human infection by adult Spirometra erinacei were proved by collection of worms in Korea. The patients were 24 and 21-year old males residing in a mountainous village in Kangwon-do. They had the clinical complaints of abdominal pain and epigastric discomfort, revealing the diphyllobothriid eggs, 53~59 x 37~42 micrometer in size, in their stools. They were treated with 500 mg atabrine and purgated with magnesium salts, and 3~4 hours later several chains of tapeworm segments were recovered from the diarrheal stools. The recovered worms revealed the morphological characteristics of spiral-form or coiled uteri, separated vaginal opening from the cirrus sac, incorporated seminal vesicle into the cirrus sac, distribution of testes at the junction between proglottids, asymmetrical eggs with one pointed eggs, etc. and were identified as Spirometra erinacei(Rudolphi, 1819). The cases had the history of eating raw flesh of the snakes and these are considered the source of infection.

The Korean Journal of Parasitology.1984;22(1):61-65. doi:10.3347/kjp.1984.22.1.61

A mass fecal examination was performed in Seoul, Korea from December 1983 to March 1984 and 15 egg positive cases of Fibricola seoulensis were discovered. They were treated with praziquantel(Distocide) 20 mg/kg single dose and magnesium salt for purgation. The adult worms of F. seoulensis were collected from 6 of them. The number of the flukes ranged 1-78 by the case. The cases had no clinical mainfestation at all. They were all Korean males in twenties, and had the histories of eating the roast or raw snakes or frogs. Fibricoliasis is expected to be prevalent among the snake-eaters in Korea. Further cases will be detected by sedulous differentiation of thin-shelled immature operculated eggs of 0.081-0.102mmn length. Praziquantel seems to be an excellent chemotherapeutic for fibricoliasis.

Studies on intestinal trematodes in Korea XIII. Two cases of natural human infection by Heterophyopsis continua and the status of metacercarial infection in brackish water fishes.

Byong Seol SEO ; Soon Hyung LEE ; Jong Yil CHAI ; Sung Jong HONG

The Korean Journal of Parasitology.1984;22(1):51-60. doi:10.3347/kjp.1984.22.1.51

Two cases of natural human infection by Heterophyopsis continua (Heterophyidae) were identified by collection of adult worms in 1983 in Korea. And in order to know the source of infection a study on fish intermediate hosts was performed along the southwestern coastal areas. The cases were 24 and 50-year old males residing in southern coastal areas. They had the clinical complaints of non-specific gastrointestinal symptoms such as epigastric pain and one of them also complained the discharge of tapeworm segments. Praziquantel in single dose of 10~15 mg/kg was given followed by purgation with mangnesium salt and 2 and 46 specimens of H. continua were collected from the diarrheal stools. They said to have eaten raw flesh of several kinds of brackish water fishes. The results of fish examination for metacercarial infection were as follows: Seventeen (63.0%) out of 27 perches (Lateolabrax japonicus) and 10 (29.4%) out of 34 gobies (Acanthogobius flavimanus) harboured the metacercariae but none of 42 mullets (Mugil cephalus) were found to harbour them. The average metacercarial density in perches was 55.4 and 18.7 per fish respectively. And the majority of the metacercariae were collected from the muscle of body portions in these fishes. After the metacercariae were experimentally fed to two rats and one young dog, two adult worms were recovered from the dog while none from the rats. These worms were also indentified as H. continua. From the results it was concluded that the brackish water fishes which the human cases said to have eaten were the source of infection.
