Gymnophalloides seoi has drawn medical attentions since the discovery of the first human case and a highly endemic area on a southwestern coastal island of Shinangun, Korea. Marine bivalves especially oysters were strongly suspected as the source of infection. In this study the oysters, Crassostrea gigas, naturally produced from the endemic area were examined whether they contain gymnophallid metacercariae.
All of 50 oysters examined were infected with the metacercariae of a gymnophallid,with the metacercarial density per oyster of 610 on average (2-4, 792 in range).
Later they were identified as G. seoi by obtaining adult worms from experimental mice. The metacercariae were unencysted, and firmly attached on the mantle surface of the oysters with their oral sucker. In sectioned specimens they were equipped with the ventral pit, a peculiar organ of the genus Gymnophalloides, and non-muscular genital pore which was connected dorsally to the seminal vesicle. The seminal vesicle was in a great majority mono-sac. By this study, it has been confirmed that the oyster is a 2nd intermediate host of G. seoi as well as the major source of human infection with this fluke.

The study made an observation on periodicity of oviposition, and the effects of nutrient and salinity in egg and larval development of Aedes togoi, and the results are summarized as follows: The 53.9% mosquitoes of one feeding laid eggs once, 26.9% laid twice and 19.2% laid three times.
Autogenous rate of Aedes togoi reared in three different nutrient groups in larval sage was 6.9% in 0.8 mg/larva, 22.5% in 1.6 mg/larva and 44.4% in 2.4 mg/larva. The oviposition rate according to different salinity of the oviposition sites (0%, 0.5%, 1.0%, 2.0% and 4.0%) was 25.2% in distilled water, 36.2% in 0.5% salinity, 23.5% in 1.0% salinity and 14.6% in 2.0% salinity. Developing period of the aquatic stage of male Aedes togoi in 25 degrees C were shorter (10.73 days) than females (11.85 days). The most effective concentration of salinity for the developing period was 1.0% which took 9.25 days in males and 10.44 days in females. In the developmental status of the follicles according to nutrition in the larval stage, the numbers of follicles of groups fed 0.8 mg, 1.6 mg and 2.4 mg per larva were 180.7, 197.5 and 202 respectively. The result of ovary dissection on the 10th day after emergence, three different nutrition groups were in Christopher's stage IIa mostly; each 71.0%, 61.1% and 39.9% of the total follicles and autogenous females observed.

Ecological studies of Aedes togoi, the vector of malayan filariasis, were carried out at Tolsando, Yosu and Sokcho area in 1991. The adult population of Aedes togoi was continuously appeared from the first week of April to the end of November showing the highest density in July. The larvae of Aedes togoi were found at rock pools from March to December in Sokcho area and the density was highest in July and August, whereas in the southern coastal area (Yosu), the larvae were found throughout the year and the density was the highest in June. The rate of larvae inhabited below 0.5% salinity was 45.7% in Sokcho and 51.7% in Yosu. The feeding activity of Aedes togoi was nocturnal, with the peak period of 01:00-03:00 hours. Indoor feeding activities were slightly higher than outdoors showing the biting ratio of 1:0.8 (indoor: outdoor). The average number of Aedes togoi attracted to CO2 gas was 8.5 whereas 117 Anopheles sinensis was attracted. The result indicates that CO2 is not an effective attractant for host seeking of Aedes togoi compared to Anopheles sinensis. The most common place was bedroom with 54.5% of total collections and next to stock place (18.2%), floor (9.1%) and kitchen (9.1%).

Comparative epidemiological studies on vector reservoir animals of tsutsugamushi disease were carried out in between south coast (the highest endemic) areas and east coast (low endemic) areas in October 1993. Fauna of field rodents and their population densities were not different between two areas. Antibody positive rate of Apodemus agrarius sera was higher in east coast (43.2% in south coast and 63.6% in east coast). High correlation (r = 0.87) was shown between antibody positive rate of A. agrarius sera and population density of the vector mites (Leptotrombidium scutellare and L. pallidum). L. scutellare was predominant in south coast, showing 110.6 chigger index (74.9% of the total chiggers), whereas L. pallidum was predominant in east coast, showing 126.3 chigger index (60.4% of the total). As higher population density of L. scutellare was found in south coast where the prevalence rate of tsutsugamushi disease is the highest, it is believed that L. scutellare is more important vector species than L. pallidum, which may result from more frequent vector-human contact.

Neodiplostomum seoulensis, one of the human intestinal trematodes, was reinfected to albino rats, and worm recovery rates, histopathology and activity changes of the intestinal brush border membrane bound enzymes were observed. The experimental groups were three; uninfected, primary infection and reinfection. The worm recovery rate in the reinfection group was much lower than in the primary infection group 14 days after infection. The duodenal histopathology showed villous atrophy during the first and second week in the primary infection group. In the reinfection group, however, villous changes occurred as early as 3 days after the infection, and the lesion was found healed 7 days after infection. The activities of alkaline phosphatase and sucrase in the duodenum of primary infection rats decreased nearly half of the controls 2 weeks after infection, whereas the activities were unchanged in the reinfection group. However, no changes in the activities were observed in the proximal jejunum between the experimental groups. These findings suggested that a secondary infection of N. seoulensis in rats should make less damage on the intestinal mucosa than a primary infection.

Two-day-old chickens and mallards were orally inoculated with one of 5 doses varying from 2 x 10(2) to 2 x 10(6) of C. baileyi oocysts per individual. Generally, the more oocysts inoculated were, the longer the patent periods were, and the more oocysts shedding were. Meanwhile increasing the inoculative dose, the prepatent periods were shortened except that mallards inoculated with 2 x 10(2) and 2 x 10(3) oocysts failed to produce the oocysts. The more parasites involving oocysts appeared from the chicken in comparison to the mallard. In the chickens challenged with a single dose of 2 x 10(6) oocysts, a small number of oocysts were detected from feces on days 4-14 after challenge infection (ACI) in all of carrageenan administered groups and in the control groups inoculated with 2 x 10(2) and 2 x 10(3) oocysts. In the mallards, a few oocysts were also recognized on days 5-15 ACI in all of carrageenan treated groups and in the control groups inoculated with 2 x 10(2), 2 x 10(3) and 2 x 10(4) oocysts. Just prior to challenge infection, phagocytic activity of peritoneal macrophages (Mo) and the number of peripheral Mo in both birds were significantly decreased in the carrageenan treated groups as compared to the control groups. Mild challenge infection in both birds denoted that the immunogenicity of C. baileyi to the birds was very strong, despite Mo blocker carrageenan administration.

To observe the production of IgA in Balb/c mice with neodiplostomiasis, 20 mice were infected with each 200 metacercariae of Neodiplostomum seoulenis. Sera and the duodenums were obtained 3, 7, 14, 28 days post-infection (PI) from five mice each group. Neodiplostomum specific IgA in serum by the enzyme-linked immunosorbent assay increased from 7 days PI and persisted till 28 days PI.
Immunohistochemistry for IgA was done with sections of the duodenum. The IgA-positive reaction was generally seen in the lamina propria and submucosa. Some of epithelial cells were positive at 7 and 14 days PI. The present finding showed that Neodiplostomun specific IgA antibody increased in serum and that there was local reaction of IgA in the mucosa and submucosa of the duodenum but not directly related with worm expulsion.

Gymnophalloides seoi, a new intestinal trematode of humans transmitted by oysters on a southwestern island of Korea, drew medical attentions because of its possible relationship with evoking pancreatitis or other pancreatic diseases. We experienced two interesting cases of G. seoi infection who were accompanied with diabetes mellitus. In routine stool examination, eggs of a gymnophallid were detected from two patients, and after treatment with praziquantel and purgation, 772 and 10 adult flukes were recovered respectively. They were identified as G. seoi. The first patient was a 62-year old man who lived in Mokpo, nearby the known endemic area, and the second patient, a 54-year old woman who lived in Inchon. They used to eat raw oysters. It should be ruled out that G. seoi infection has some relationship with pancreatic diseases.

We examined stool specimens of the residents in the emigration camp in Tijuana, Mexico for helminth eggs or protozoan cysts with formalin-ethyl acetate concentration method in February and July 1992. Out of 92 examined samples, number of positive was 49 (53.3%). While number of cumulative positive was 66 (71.7%). Cysts of Entamoeba coli (29.3%) Giardia lamblia (9.8%), Entamoeba histolytica (7.6%), and eggs of Taenia spp. (6.5) were most frequently observed. Filtered water supply and chemotherapy were required in this camp.
