Stray cats are a common feature roaming the streets and alleys of Kuwait; they could be a source of parasites, including trematodes, that affect humans. A survey was conducted to identify feline trematodes and throw the light on their public health significance in Kuwait. Out of 240 stray cats trapped from different localities of Kuwait from June 2011 to May 2012, 59 (24.6%) were found to be infected with 14 species of trematodes. The most common were trematodes of the genus Heterophyes, particularly H. heterophyes and H. dispar that were found in respectively 15.8% and 10.8% of the cats examined. Other trematodes recorded, with lower prevalences, were Heterophyes nocens (2.9%), Haplorchis taichui (3.8%), Stictodora sawakinensis (2.1%), Stellantchasmus falcatus (1.6%), Echinochasmus japonicus (1.6%), and Mesostephanus dottrensi (1.3%). Centrocestus cuspidatus, Galactosomum fregatae, Ascocotyle sp., Mesostephanus appendiculatus, Haplorchis yokogawai, and Pygidiopsis genata showed the lowest prevalence (0.4%) and intensity. The majority of the trematodes are recorded for the first time in Kuwait and even in the Gulf region. The study reveals that stray cats are good indicators of fish-borne trematodes in the environment. As all trematodes recovered are zoonotic, their significance to public health should be considred.

Nine (34.6%) of the 26 rockfishes taken from Newport fish market, Oregon in July 2003 had a total of 135 monogenetic trematodes attached the gills. Microcotyle sebastis, Megalocotyle trituba and Trochopus australis were encountered, occurring in rockfishes examined. In the monogenetic trematodes in Sebastes spp, the prevalence were found to be between 30.8 and 40.0%. Prevalence of M. sebastis was 37.5%, 40.0% on M. trituba and 30.8% on T. australis. Nine of Sebastes spp. were infected with one or two species of monogenetic trematodes. Intensities of infection for M. sebastis, M. trituba and T. australis were recorded as 2.0 (2-12), 22.0 (48-62) and 1.0 (1-3), respectively. It may be that the intensities of infection for M. trituba should be high, and M. sebastis and T. australis little low.

The study of the gill infection of rockfishes, Sebastes spp. by monogenetic trematodes conducted during March 2002 to June 2002 are presented. Three species are reported krom examination of 23 rockfishes collected from Oregon Coast Aquarium and Newport fish market, Oregon. Ten rockishes belonging to three species showed an infection rate of 43.5%. A total of 135 monogenetic trematodes was found in the gills of Sebastes spp. Of 135 worms recovered from the gills of 4 harbor rockfishes, two were Sebastes maliger, 14 S. melanops, 110 S. pinniger, and 9 S. crameri. Prevalence and intensity in Microcotyle seba.fis were 11.9％ and 4.0, and for Trochopus trituba they were 81.5% and 55.0, and for Trochopus australis, they were 6.7% and 2.3, respectively. These worms are mainly found firmly attached to the primary lamellae of the gills of the rockfishes.

In order to evaluate prevalence and perception on the intestinal trematodes of inhabitants at Docho-island, Shinan-gun, Chollanam-do, a questionnaire survey for the epidemiological study and stool examination for the detection of the eggs of the trematodes were done on 224 individuals at the island from January to February, 2000. The results were as follows: 1. Egg positive rate of the intestinal trematodes was 21.0%. 2. The egg positive rate has revealed significantly higher in the elderly over age 70 than other ages, higher in seashore villagers than inland ones, and higher in persons who had a rural and/or marine ph than persons with other jobs, respectively(P<0.05). 3. The egg positive rate of alcoholic drinkers was higher than non-alcoholic persons, and the rate was also higher in smokers than non-smokers. It was statistically significant(P<0.05). 4. The egg positive rate was shown to be significantly higher in inhabitants who ate raw mullet that was well known to be the source of infection with the intestinal trematodes than people who did not eat the raw marine fishes(P<0.01). 5. The egg positive rate was also significantly higher in humans who had the complaints of frequent abdominal pain and diarrhea than healthy people(P<0.05). In conclusion, the prevalence of intestinal trematodes at the island located in the south and west area in Korea was too high to eradicate the parasitic infections. So a special program is necessary for the control of the trematode infections in many adjacent islands at Chollanamdo.

The anthelmintic efficacy of Albendazo1e and Ivermectin against gastrointestinal nematodes, trematodes and cestode was tested in naturally infected Korean native goats. Albendazole was medicated at a dose rate of 10mg/kg of body weight orally and Ivermectin was injected at a dose rate of 0.2mg/kg of body weight subcutaneously. The efficacy was measured by faecal examinations on the day 7th and the day 14th :after treatment. The results obtained were summarized as follows : 1. The efficacy of Albendazole against trematodes and cestode was shown 91.7% in Fasciola hepatica, 68.8% in Paramphislomum spp., 66.7% in Eurytrema pancreaticum and 100% in Moniezia expansa(cestode). 2. The efficacy of Ivermectin against trematodes and cestode was shown 38.8% in Fasciola hepalica, 26.1% in Paramphistomum spp., 22,2% in Eurytrema pancreaticum and 100% in Moniezia expansa(cestode). 3. The anthelmintic efficacy of Albendazole against gastrointestinal nematodes was shown 97.7% in Haemonchus contorus and 100% in Oesophagostomum spp., Ostertagia spp., Bunostomum trigonocephalum, Trichostrongylus spp., Strongyloides papillosus and Cooperia spp. 4. The efficacy of Ivermectin against gastrointestinal nematodes was shown 96.6% in Haemonchus contortus, 94.1% in Trichostrongylus spp. and 100% in Oesophagostomum spp., Ostertagia spp., Bunostomum trigonocephalum, Strongyloides papillosus and Cooperia spp.

Four genera of metazoan parasites were recovered from 3 of 6 Sebastes pinniger examined during January 2003. Two hundred forty-five metazoan parasites were recovered. Trochopus trituba Sekerak and Arai, 1977 and Anisakis larvae were found to he infected S. finniger Gill and te be abundant in this rockfish. One hundred eleven worms of monogenean trematodes and 134 larval anisakine nematodes were also found in this fishes. Precise positions with regard to gills, fins, and gastrointestinal tracts were recorded on S. pinniger to determine distribution of metazoan parasites of Trochopus trituba, Anisakis simplex larva, Contracaecum sp. larva, and Pseudo terranova decipiens larva. The monogenean trematodes, T. trituba were attacked to the gill arches and fin, and the larval anisakine nematodes, A. simplex, Contracaecum sp.,and P. decipiens were found on the visceral organs such as intestine, omentum and stomach wall. The second gill arches were the most heavily infested and posterodorsal region of the gill arches contained most monegenenn trematodes. The nam site of infestation of larval anisakine nematodes were the intestine.

Monogeneans(Phylum Platyhelminthes) have been known as common parasites onto the skin and gills of cultured freshwater fishes. Infestation with these parasites result in a great loss in aquaculture industry. Some classification studies on these parasites have mostly been conducted in Japan but rarely in Korea. For the purpose of classifying monogenean parasites infesting two Korean freshwater fishes, eel (Anguilla japonica) and catfish(Parasilurus asotus), samples captured from March 1998 to April 2000 were examined. Here we report for the first time in Korea that four different species of monogeneans are identified: Pseudodactylogyrus bini and P. anguillae in eels; Ancylodiscoides infundibulovagina and Ancylodiscoides sp. in catfish.
