  • 프라지관텔 주사제의 조충류 피료 효과를 평가하였다. 개, 고양이, 산양, 사슴, 닭, 쥐 및 마우스 등 총 93마리 동물의 장관내에 기성하는 조충류 dipylidium caninum, Taenia pisiformis, Spirometra sp., Taenia taeniaeformis, Moniekia expanse, Moniexia sp., Raillietina sP. 및 인ymenolepis nana에 체중 kg당 프라지콴텔 12 mg, 9 mg, 6 mg, 3 mg, 1.5 mg을 대퇴부에 근육주사한 후 치료효과를 판정하였다. H. nana에 감염된 마우스는 6mg/kg 투여 후 3시 간부터 6시 간 사이에 충체를 배출하였다. 다른 조충류도 약제투여 48시 간 이내에 모두 체외로 배출되었다. H. nana 및 M. expansa를 제외한 모든 충체는 체외 배출시 심하게 손상되어 있었으며, D.cnninum의 충란낭은 붕괴되어 충란이 분리되었다. 조충의 종류와 감염강도 등에 따른 숙주 체중 kg당 투여 용량의 차이는 관찰되지 않았으며 Spirometra sp.에 감염되었던 한 마리의 개를 제외하고는 프락지관텔 6 mg/kg 1회 용량으로 완치되어 97.9% (46/47)의 치유율을 보임으로써 우수한 치료 효과를 나타내었다.

  • Zoonoses are those diseases and infections that are naturally transmitted between vertebrate animals and man. At present, approximately 175 diseases caused by virus, rickettsia, bacteria, protozoa and helminthes as well as some of arthropods and the number is continually increasing. Although zoonoses are generally recognized as significant health problems, the actual prevalence and incidence of zoonotic infections is difficult to determine. Medical services in a rural area are scarce and ill persons may have little chance to see a physician. Furthermore, a lack of physician awareness and of appropriate diagnostic support is made often misdiagnosis. In rural Korea, parasitic disease is still important subject in the field of zoonotic infections considering its number and morbidity. Recently there was conspicuous reduction of soil-transmitted parasitic diseases (i.e. ascariasis. hookworms, trichuriasis), but clonorchiasis. intestinal trematodiases and taeniasis are a considerable problem. This is often significantly related to human behavioral patterns based on socio-economic and cultural conditions and linked with the local biologic and physical environment. The most of all parasitic zoonoses to man and animals are the food-transmitted parasitic diseases, and domestic animals such as dog, cat, pig, as well as fat and some mammals, ruminants and birds are act as reservoir hosts. In the present topics, current problems of parasitic zoonoses caused by protozoan infections (i. e. toxoplasmosis, pneumocystosis and cryptosporidiosis) which are the most common opportunistic in AIDS or immunocompromised persons, trematode infections (i.e. clonorchiasis, paragonimiasis and some intestinal tremadodiases). cestode infections such as cysticercosis and sparganosis, and some nematode infections of anisakiasis, thelaziasis and strongyloidiasis, are discussed here those on the occurrence in man and animals and the source of transmission as well as prevention and control measures in Korea.

  • The objective of this study was to investigate the prevalence of tick-borne pathogens in the Korean water deer (Hydropotes inermis argyropus). Pathogens were identified using PCR which included Anaplasma, Ehrlichia, Rickettsia, and Theileria. Rickettsia was not detected, whereas Anaplasma, Ehrlichia, and Theileria infections were detected in 4, 2, and 8 animals, respectively. The most prevalent pathogen was Theileria. Of the 8 Theileria-positive animals, 2 were mixed-infected with 3 pathogens (Anaplasma, Ehrlichia, and Theileria) and another 2 animals showed mixed-infection with 2 pathogens (Anaplasma and Theileria). Sequencing analysis was used to verify the PCR results. The pathogens found in this study were identified as Anaplasma phagocytophilum, Ehrlichia canis, and Theileria sp. To the best of our knowledge, this is the first report identifying these 3 pathogens in the Korean water deer. Our results suggest that the Korean water deer may serve as a major reservoir for these tick-borne pathogens, leading to spread of tick-borne diseases to domestic animals, livestock, and humans. Further studies are needed to investigate their roles in this respect.

  • Medically important arthropods, including fleas, play an important role in causing clinical disorders and disease in man and domestic animals. This study was conducted to determine the seasonal flea infestations for domestic dogs from different geographic regions of Iran. A total of 407 fleas, belonging to 5 different species, were recovered from 83 domestic dogs from 3 regions. There was a distinctive pattern of species distribution and infestations with the highest infestation rates observed in a temperate climate and higher rainfall. Additionally, fleas were observed over all seasons, except February and March, with the highest infestation rate observed in August (24.7%) and the lowest rate in January (1.7%). They also parasitize dogs with a different spectrum of species. The cat flea, Ctenocephalides felis (67.5%), exhibited the highest prevalence among all flea species found on dogs. Thus, climatic conditions and seasonal patterns impact on flea infestation and must be considered in developing control programs.

  • The study was attempted to scrutinize the normal osmotic fragility of erythrocytes in domestic poultry such as chicken, quail and duck, making a comparison with that in domestic mammalia such as dog and pig. Osmotic fragility of erythrocytes was determined on blood samples from 10 healthy adult animals in each species. Optical initial hemolysis of erythrocytes occurred at $0.395{\pm}0.03%$ NaCl for chicken, $0.410{\pm}0.03%$ for duck, $0.440{\pm}0.02%$ for quail, $0.470{\pm}0.05%$ for dog and $0.560{\pm}0.03%$ for pig. Optical complete hemolysis of erythrocytes occurred at $0.270{\pm}0.02%$ NaCl for chicken, $0.305{\pm}0.03%$ for duck, $0.360{\pm}0.02%$ for quail, $0.370{\pm}0.03%$ for dog and $0.455{\pm}0.03%$ for pig. In other words, erythrocytes of poultry have stronger resistance to osmotic lysis than those of mammalia, showing the strongest resistance in chicken among the tested poultry.

  • Phthalates and di-2-ethylhexyladipate are both widely used as industrial chemicals and exposure high levels over long periods of time can cause toxicity, estrogenic responses and endocrine disruption properties in both humans and animals. So far, their global monitoring in environmental matrices has been performed continuously. A developed method, including modified SPEED'98 (Japan Environment Agency) and USEPA was established for simple and rapid determination of phthalates and di-2-ethylhexyladipate in various matrices. This method was applied to explore the distribution levels in domestic environmental media such as water, soil and sediment. Eight phthalates (DEP(di-ethyl), DEHP(di-[2-ethyl-hexyl]), DprP (di-propyl), DBP(di-n-butyl), DPP(di-n-pentyl), DHP(di-n-hexyl), DCHP(di-cyclohexyl), BBP(butyl benzyl) and Adipate (di-2-ethylhexyl adipate) were investigated by seasonal sampling(spring, autumn) at 24 domestic sites. Phthalates and adipate were not detected in water samples and DEP, DBP, and DEHP were mainly detected in soil and sediment samples. The concentrations of DEP and DBP excluding DEHP in spring were higher in soil than those of sediment. Total concentrations of phthalates were significantly decreased in autumn for both soil and sediment.

  • The purpose of this study was to isolate and characterize bacteriocin-producing bacteria against Clostridium perfringens from domestic animals to determine their usefulness as probiotics. The feces of cattle and chicken were used as sources to isolate bacteriocin-producing bacteria using the spot-on-lawn method. In total, 900 bacterial stains were isolated from domestic animal feces, and 19 strains were finally selected after determining the inhibitory activity against the pathogenic indicator C. perfringens KCTC 3269. Eighteen strains of Bacillus subtilis and one strain of Brevibacillus parabrevis were identified by 16s rRNA sequencing. Most of the bacterial strains isolated were resistant to 0.5% bile salts and remained viable after 2 h at pH 3.0. Additionally, some B. subtilis strains showed strong inhibitory activity against Listeria monocytogenes. We isolated and screened B. subtilis strains CB 153 and CB 189 from cattle and B. subtilis MSC 156 and B. parabrevis MSC 164 from chickens using probiotic selection criteria such as inhibition activity against C. perfringens and tolerance to acid and bile salts. The isolated bacteriocin-producing bacteria and/or bacteriocin have the potential to be used as probiotics in the livestock industry.
