Double-stranded RNA virus in Korean Isolate IH-2 of Trichomonas vaginalis
Jong Wook Kim, Pyung-Rim Chung, Myung-Ki Hwang, Eun Young Choi
Korean J Parasitol 2007;45(2):87-94.
Published online June 20, 2007
DOI: https://doi.org/10.3347/kjp.2007.45.2.87

In this study, we describe Korean isolates of Trichomonas vaginalis infected with double-stranded (ds) RNA virus (TVV). One T. vaginalis isolate infected with TVV IH-2 evidenced weak pathogenicity in the mouse assay coupled with the persistent presence of a dsRNA, thereby indicating a hypovirulence effect of dsRNA in T. vaginalis. Cloning and sequence analysis results revealed that the genomic dsRNA of TVV IH-2 was 4,647 bp in length and evidenced a sequence identity of 80% with the previously-described TVV 1-1 and 1-5, but only a 42% identity with TVV 2-1 and 3 isolates. It harbored 2 overlapping open reading frames of the putative capsid protein and dsRNA-dependent RNA polymerase (RdRp). As previously observed in the TVV isolates 1-1 and 1-5, a conserved ribosomal slippage heptamer (CCUUUUU) and its surrounding sequence context within the consensus 14-nt overlap implied the gene expression of a capsid protein-RdRp fusion protein, occurring as the result of a potential ribosomal frameshift event. The phylogenetic analysis of RdRp showed that the Korean TVV IH-2 isolate formed a compact group with TVV 1-1 and 1-5 isolates, which was divergent from TVV 2-1, 3 and other viral isolates classified as members of the Giardiavirus genus.

Corbicula fluminea (Bivalvia: Corbiculidae): a possible second molluscan intermediate host of Echinostoma cinetorchis (Trematoda: Echinostomatidae) in Korea
Pyung-Rim Chung, Younghun Jung, Yun-Kyu Park, Myung-Gi Hwang, Chin-Thack Soh
Korean J Parasitol 2001;39(4):329-332.
Published online December 31, 2001
DOI: https://doi.org/10.3347/kjp.2001.39.4.329

More than 1,500 clams of Corbicula fluminea, the most favorable food source of freshwater bivalves in Korea, were collected from 5 localities to examine cercarial and metacercarial infection with Echinostoma cinetorchis. Although 3 clams infected with suspicious E. cinetorchis metacercariae out of 200 specimens collected at Kangjin, Chollanam-do were detected, no cercarial and metacercarial infections with E. cinetorchis were observed in field-collected Corbicula specimens. In the susceptibility experiments with laboratory-reared clams, those infected with miracidia of E. cinetorchis did not release their cercariae up to 60 days after infection. To confirm the identity of second intermediate host of E. cinetorchis experimentally, a total of 30 clams were exposed to the cercariae from Segmentina hemisphaerula that had been infected with miracidia of E. cinetorchis. The clams were susceptible to cercariae of E. cinetorchis with an infection rate of 93.3%. Metacercariae from clams taken more than 7 days after cercarial exposure were fed to rats (S/D strain), and adult worms of E. cinetorchis, characterized by 37-38 collar spines on the head crown, were recovered from the ileocecal regions. This is the first report of C. fluminea as a possible second intermediate host of E. cinetorchis.

Austropeplea ollula (Pulmonata: Lymnaeidae): A new molluscan intermediate host of a human intestinal fluke, Echinostoma cinetorchis (Trematoda: Echinostomatidae) in Korea
Pyung-Rim Chung, Younghun Jung, Yun-Kyu Park, Myung-Ki Hwang
Korean J Parasitol 2001;39(3):247-253.
Published online September 30, 2001
DOI: https://doi.org/10.3347/kjp.2001.39.3.247

Three freshwater snail species of the family Lymnaeidae have been reported from Korea, Radix auricularia coreana, Austropeplea ollula and Fossaria truncatula. Out of 3 lymnaeid snail species, A. ollula was naturally infected with the Echinostoma cinetorchis cercariae (infection rate = 0.7%). In the experiments with the laboratory-bred snails, F. truncatula as well as A. ollula was also susceptible to the E. cinetorchis miracidia with infection rates of 25% and 40%, respectively. All of three lymnaeid snail species exposed to the E. cinetorchis cercariae were infected with the E. cinetorchis metacercariae. It is evident that A. ollula acts as the first molluscan intermediate host of E. cinetorchis in Korea, and F. truncatula may be a possible candidate for the first intermediate host of this intestinal fluke. Also, three lymnaeid snail species targeted were experimentally infected with E. cinetorchis metacercariae.

Immunoelectron microscopic localization of partially purified antigens in adult Paragonimus iloktsuenensis
Ok-Ran Lee, Pyung-Rim Chung
Korean J Parasitol 2001;39(2):119-132.
Published online June 30, 2001
DOI: https://doi.org/10.3347/kjp.2001.39.2.119

An immunoelectron microscopy employing immunogold labeling method was performed to detect tissue origin of D1 fraction (D1A) among 5 antigenic protein fractions partially purified by DEAE-anion exchange chromatography from water-soluble crude antigen (PIWA) of adult Paragonimus iloktsuenensis. Immune reactions of adult worm tissues with rabbit serum immunoglobulin immunized with crude antigen (PI-Ig) and D1 antigen (D1-Ig), as well as rat serum immunoglobulin infected with P. iloktsuenensis were observed. D1A showed strong antigenicity in the intestinal epithelium of the worms during the early infection period of 2-4 weeks after infection. The vitellaria also showed stronger antigenicity than the other tissue sites in immune reaction of tissues against all immunoglobulins from 4 to 33 weeks after vitelline development. Therefore, it is suggested that D1A was mainly originated from the intestinal epithelial tissues before the development of vitelline gland of the parasites. Immuno-reactivity of two immunoglobulins (PI-Ig, D1-Ig) was significantly different in intestinal epithelial cytoplasmic protrusions (CP) and intestinal epithelial secretory granules (SG). In the experimental group with D1-Ig, gold particles were labeled significantly in CP than in SG when compared to the PI-Ig group. Thus, the major antigenic materials in D1 antigen having a strong antigenicity in the early infection period was considered to be originated from the intestinal epithelial tissue.

Non-specific activation of mouse peritoneal macrophages by a freshwater ciliate, Tetrahymena pyriformis
Younghun Jung, Ki-Sun Kim, Pyung-Rim Chung
Korean J Parasitol 2000;38(2):65-74.
Published online June 30, 2000
DOI: https://doi.org/10.3347/kjp.2000.38.2.65

Toxoplasma-killing activities of mouse peritoneal macrophages activated by the extracts of Tetrahymena pyriformis (Korean and Chinese strains) were evaluated, and the active protein fractions from both strains were partially characterized by a method including chromatographies and SDS-PAGE. The first peak in Korean strain and the second peak in Chinese strain of T. pyriformis obtained by DEAE-Sephadex A-50 chromatography were most effective in the activation of macrophages to kill Toxoplasma gondii tachyzoites in vitro. Subsequent fractionations of obtained peak fractions were performed on a Sephadex G-200 gel. The first peaks fractionated from both strains of T. pyriformis had the highest toxoplasmacidal activities, and when subjected to the SDS-PAGE, one prominent band was visualized for each of the strains showing the same molecular weight of ca. 52.6 kDa. This active protein is suggested to be related to non-specific activation of mouse peritoneal macrophages.

Karyotypes on three species of Chinese mesogastropod snails, Semisulcospira libertina, S. dolichostoma and Viviparus rivularis
Gab-Man Park, Jae-Jin Kim, Pyung-Rim Chung, Yong Wang, Duk-Young Min
Korean J Parasitol 1999;37(1):5-11.
Published online March 31, 1999
DOI: https://doi.org/10.3347/kjp.1999.37.1.5

Three species of the families Viviparidae and Pleuroceridae, the first intermediate host of paragonimiasis, metagonimiasis and echinostomiasis were studied cytologically. The observed diploid chromosome number was as follows: Semisulcospira libertina 36, S. dolichostoma 34, and Viviparus rivularis 64. The mitotic chromosome complement of S. libertina has nine metacentric pairs and nine submetacentric pairs, and S. dolichostoma has three metacentric pairs and 14 submetacentric pairs of chromosomes. Viviparus rivularis showed two metacentric pairs and 30 submetacentric pairs of chromosomes.
