Frog culture industry is not yet familiar but has much potential. Generally, in farm, the population density is higher than that of in nature and frog farm is not the exception. But when population density is high, it can easily leads to stressful condition, poor sanitation. When a disease occur, it is a primary factor that makes the population more susceptible and the results more grave. Because of severe Rhabditoidea- helminth infection and subsequent bacterial septicemia, 50~70% of the total population had been died in a farm in Jeong-sun in Gangwon-do and Chungju in Chungcheongbuk-do from late June, 2012 to September, 2012. Diseased frogs showed ruptured lung, bloody ascites, liver discoloration, myocardium weakness, congested kidney, microcytic anemia and so on. Enterobacteriacea, Citrobacter.sp, Cupriavidus metallidurans, Acinetobacter.sp were isolated as major bacterium that had caused septicemia in frogs. Among isolated bacterium, Cupriavidus metallidurans, Ewingella americana, Shewanella aquimarina and Pseudoalteromonas sp. have not reported as potential pathogens in frogs before. It is a good example that severe helminth infection in frogs can lead to secondary infection of bacteria.

The prevalence of liver and intestinal helminth infections, including Opisthorchis, Haplorchis, Phaneropsolus, hookworms, Enterobius, and Taenia, was surveyed in Khammouane province, Lao PDR. Fecal specimens were collected from 1,242 people (590 men and 652 women) in 3 Mekong riverside villages and were examined by the Kate-Katz thick smear technique. The overall helminth egg positive rate was 81.1%. The positive rate for small trematode eggs, including Opisthorchis viverrini, heterophyids, and lecithodendriids, was 81.1% and the positive rate for hookworms was 6.7%. To obtain adult worms, 35 people who were positive for small trematode eggs were treated with 20-30 mg/kg praziquantel and 10-15 mg/kg pyrantel pamoate, and then purged. Diarrheic stools were collected from 33 of these people and searched for helminth parasites using a stereomicroscope. Mixed infections with various helminths (Haplorchis taichui, Haplorchis yokogawai, Prosthodendrium molenkampi, Phaneropsolus bonnei, echinostomes, hookworms, Trichostrongylus spp., Trichuris trichiura, Enterobius vermicularis, and/or Taenia saginata) were found. The total number of helminth specimens collected was 20,907 (approximately 634 per person). The most common species was H. taichui, followed by P. molenkampi, 0. viverrini, P. bonnei, E. vermicularis, hookworms, and Trichostrongylus spp. These results show that diverse species of intestinal nematodes, trematodes, and cestodes are infecting humans in Khammouane province, Lao PDR.

대구시민들에 있어서 장내 기생광충류의 최근 감염상을 알아보기 위해 1983연 3월부터 9월까지 대구시내 5개동(남구 봉덕동, 북구 노원동, 서구 비산동, 동구 신암동 및 수성구 수성동)주민를 조사 대상으로 선정하여 formalinether 집란법 및 scotch-tape 항문주위도말법으로 광충류 충란 검사를 실시하였다. 총 피검자 1,697명중 장내접충류 감염률은 27.9%이었으며, 이중 편충이 13.2%로 가장 높았고, 그 다음은 7.0%를 나타내는 요충이었으며, 구충은 0.:1로 가장 낮았다. 성별 감염률에 있어서 남자의 경우 간흡충, 요꼬가와흡충, 조충등은 여자에 비해서 그 율이 다소 높았으나, 편충의 경우에는 양자간에 유의적 차를 인정할 수 없었다. 연령군별 감염률에 있어서는 편충은 20∼29세군에서 남자 17.5%. 여자 17.6%로 가장 높았으며, 0∼9세군에서는 남자 5.5%, 여자 9.6%로 가장 낮았다. 간흡충은 30∼39세군에서 가장 높았으며 요꼬가와흡충도 간흡충과 비슷한 양상을 나타내었다. 혼합기생상에 있어서는 1종기생이 가장 많았고 다음은 2종의 중복기생이었으며, 3종의 혼합기생은 매우 적었다. 이상의 성적으로 미루어 보아 대구직할시 주민들에서의 장내 기생 윤충류 감염은 아직도 고율임을 알 수 있었다.

A total of 2,026 leprosy patients of the National Sorokdo Hospital was examined their infestparasites by cellophane thick smear method in January, 1983. The egg positive cases of Taenia spp. were treated with bithionol and the segments of Taenia were collected for species identification. The results were as follows: 1. Total egg Positive rate of any kind helminth was 78.2% and cumulative total was 85.2%. The egg positive rate for each helminth was as follow; Taenia spp. 3.4%, Ascaris lumbricoides 4.5%, Trichuris trichiura 72.1%, Clonorchis sinensis 2.8% and other 0.05%. 2. A total of 66 Taenia eggpPositive cases was treated; out of them proglottids of Taenia were collected from 26 cases. All of the collected worms were identified as T. saginata. The results revealed signiBicantly high egg positive rate of T. trichiura. However, A. lumbricoides was found to be controlled considerably by repeated chemotherapy during past 3 years. If chromotherapeutic agent is replaced with oxantel-pyrantel tablet, better result is expected. No clue was found for prevalence of T. sodium from both human and the pig in the island.

Seven specimens of Sebastes melanops, black rockfish and three of S. maliger, quillback rockfish, were collected from Oregon Coast Aquarium during the period of September 19 to November 5, 2001 and examined for parasites. One monogenean helminth species and parasitic copepod species were recorded from black and quillback rockfishes, respectively. A total of 26 parasites were collected: 16 Microcotyle sebastis from the gill filaments of black and quillback rockfishes and 10 Clavella adunca were found in the fins of black rockfish. The prevalence of Microcotyle sebastis was 40.0%, and intensity of infection was 2.0(1-11). With regard to Clavella adunca, the prevalence and intensity were 20.0% and 1.4(2-8), respectively.

This survey conducted to know the species of helminth parasites of cats slaughtered in Daegu during the period from July to September in 1977. A total of 65 cases of internal organs of cats was used for this examination. The results obtained were summarized as follows: 1. Six species of trematodes belong to order digenea were found; Clonorchis sinensis (Cobbolt, 1875), Heteropheys heterophyes nocens (Onji et Nisinio, 1915), Metagonismus yokogawai(Katsurada, 1912), Centrocestus sp. Echinochasmus perfoliattlus (Ratz, 1908), and Echinopharyphium sp. 2. Five species except Clonorchis sinens are firstly recorded in cats in Korea.

Natural habitat fragmentation and reducing habitat quality have resulted in an increased appearance of Japanese macaques, Macaca fuscata (Gray, 1870), in suburban areas in Japan. To investigate the risk of zoonotic infections, a coprological survey of helminth eggs passed by wild Japanese macaques was carried out in 2009 and 2010 in Shiga Prefecture, Japan. Microscopic examination found helminth eggs in high prevalence, and nucleotide sequencing of DNA extracted from the eggs identified Oesophagostomum cf. aculeatum and Trichuris trichiura. A fecal culture also detected infective larvae of Strongyloides fuelleborni. These zoonotic nematodes pose a potential health issue to local people in areas frequented by Japanese macaques.

The frequent finding of soil contamination by dogs' feces are remarkable, and such soil contamination may be public health problem. Of 608 samples, 30(4.9%) were positive for nematode ova. Ten paint 3% of sail samples from parks and 7.9% from footpaths were found to contain nematode eggs. Of the helminth eggs detected, eggs of Toxocara spp. were the most commonly encountered, and mostly from the soil of footpaths. No eggs were recovered from the soil of school yards; the level of soil contamination was low in public play areas. Egg recovery rate of the soil to dogs' feces collected from footpaths was approximately 1:5. And the larvae demonstrated from the soil in the present study were nematode larvae, mainly recovered from parks.
