Author investigated internal parasitism for the feces of dog's training center, breeding-dog farm, dairy farm, home by 120 indoor breeding dog and 566 outdoor one in Inchon area. This survey was done from February in 1994 to December in 1995. 1. As a result of total 686 samples, positives were 373(54.4%). Among them, indoor and outdoor breeding dogs were 21(3.1%) 352(51.3%), respectively. 2. According to breeding, it was manifested that 21samples (17.5%) of 120 indoor breeding dogs were positive, and 352 samples(62.2%) of outdoor breeding were positive. 3. The infection rate of dogs for food in dairy farm, breeding dogs in the farm, dog of training center and dog of house is high in order. 4. Infection rate of parasites in 24 dogs breeds, Mongrel dogs were 81.3%, Shepherds were 80.0%, Tosas were 78.4%, Akida and Siberian huskys were 76.2%, Jindos were 55.5%, Pointers were 50.0%, although Afghan hound, Spanial, Shin-tzu, Maltis and Buldog were examined as aparasites negative. 5. After administration with vermicide parasites infection rate were 43.0% in two months. In four months, it were 66.7%, and dogs without vermicide were 87.0%. It seemed like that further research about dosage of vermicide is needed. 6. The rate of single-infection was 37.6% and that of mixed-infection was 16.8%. Among classified 13 types, Ancylostoma caninum 35.6%, Toxocara cams 11.2%, Isospora sp 9.3%, Toxascaris leonina 5.1%, Trychuris vulpis 4.4% were investigated.

In order to survey the prevalence of intestinal parasites in dogs, 304 fecal samples were taken from dogs in Taejon city, The prevalence and identification of intestinal parasites were determined by the fecal examinations using sheather's floating technique and sedimentation methods and then Cryptosporidium oocysts were identified by kinyoun's modified acid fast stainning method. The results were obtained as follows ; 1. Parasite eggs and oocysts were detected in 105 samples (34.5%) from 304 cases of dog feces. 2. The 11 kinds of eggs and oocysts were isolated from the feces of dog. Those were Ancylostoma caninum (12.1%, 37 dogs), Trichuris vulpis (11.5%, 35 dogs), Toxocara canis (10.2%, 31 dogs), Isospora sp (7.2%, 22 dogs), Cryptosporidium sp (3.6%, 11 dogs), Toxascaris leonine (1.9%, 6 dogs), Strongyloides sp (1.9%, 6 dogs), Taenia sp (0.6%, 2 dogs), Diphylidium caninum (0.3%, 1 dog), Spirometra sp (0.3%, 1 dog) and Clonorchis sinensis (0.3%, 1 dog). 3. It was mixed infection such as single, double, triple and quadruple, 64.8%, 25.7%, 8.6% and 0.9%, respectively. 4. In indiviually-raised 4095, the infectious late of T canis (11.4%), A Caninum(13.2%), Cryptosporidium sp (6.1%), T leontna (2.6%) were higher than those of group raised dogs. But the infectious rate of T vulpis (12.1%) in group raised dogs was higher than that of individually-raised dogs. 5. Adults of Demodex and Sarcoptes which have been found in this survey are excluded in this report.

In order to detection of the Intestinal parasites, 503 fecal samples were taken from mongorel-and pad-dogs in Chonbuk province. The prevalence and identification of intestinal parasites were determined by the fecal examinations using the floatation and /or sedimentation methods and microscopical examination, respectively. The results were obtained as follows 1. Fifty-nine percent (297 dogs) from 503 fecal samples were detected eggs. In seasonal detection rate of eggs, Summer was 30.3%, Autumn 26.4%, Winter 22.3% and Spring 21.0%, in order, 2. A total of 20 kinds of eggs were isolated from feces, and it was identified 75.7% as Nematoda(320 dogs), 5.6% as Cestoda(24 dogs) and 1.4% as Trematoda(6 dogs), and 17.2% as Protozoa(73 dogs). The isolates were identified as Ancylostoma caninum (30.4%, 153 dogs), Isospora spp. (14.3%, 72 dogs), Toxocara canis(11.1%, 56 dogs), Toxascaris leonina(5.8%, 29 dogs) , Uncineria stenocephala or Physaloptera spp. (5.4%, 27 dogs), Trichuris vulpis(2.4%, 12 dogs) and the others, single or in combination. 3. In mixed infection such as single, double, triple and quadraple was 63.6%, 31.7%, 3.4% and 1.3%, respectively.

The purpose of this study was 2-fold: 1) to investigate the prevalence of gastrointestinal parasite infection in cats reared in Daegu, Republic of Korea and 2) to assess the efficacy and safety of a topical emodepside/praziquantel formulation for cats with parasitic infections. The gastrointestinal parasite infections were examined microscopically using the flotation method. Of 407 cats, 162 (39.8%) were infected by at least one gastrointestinal parasite, including Toxocara cati (63.0%), Toxascaris leonina (31.5%), Taenia taeniaeformis (3.7%), and Cystoisospora felis (1.9%). None of the infected animals had multiple infections. When the data were analyzed according to sex, age, and type of cat, stray cats showed statistically higher prevalence than companion cats (P<0.05). On the 5th day after treatment, no parasitic eggs were detected using microscopic examination. In addition, no adverse effects, such as abnormal behaviors and clinical symptoms, were observed in the cats treated with the drug. These results quantify the prevalence of gastrointestinal parasites in cats in Daegu, Republic of Korea, and show that topical emodepside/praziquantel is a safe and effective choice for treating the parasitic infections in cats.

We present a human infection with the canine whipworm, $Trichuris$ $vulpis$, in a child suffering from rhinitis with a diagnosis of rhinitis. $T.$ $vulpis$ eggs resemble those of $T.$ $trichiura$ but they can be differentiated based on their morphological features and egg size, using micrometry with an ocular micrometer. $T.$ $vulpis$ eggs measured an average of 90 ${\mu}m$ by 44 ${\mu}m$ (range 86-99 ${\mu}m$ by 38-47 ${\mu}m$). Prevalence of hookworms (28.1%), $Toxocara$ $canis$ (11.8%), and $Trichuris$ $vulpis$ (3.5%) was found in 292 fecal samples of dogs collected at the peri-domicile, which showed that the risk of infection was not only fortuitous. The treatment of canine whipworm infections is similar to that of $T.$ $trichiura$ infection. We recommend differentiation of the 2 species for their epidemiological and prevention implications.

Shahr-e Sukhteh (meaning burnt city in Persian) in Iran is an archeological site dated back to around 3,200-1,800 BC. It is located in Sistan and Baluchistan Province of Iran and known as the junction of Bronze Age trade routes crossing the Iranian plateau. It was appointed as current study area for paleoparasitological investigations. Excavations at this site have revealed various archeological materials since 1967. In the present study, sheep and carnivore coprolites excavated from this site were analyzed by means of rehydration technique using TSP solution for finding helminth eggs. Dicrocoelium dendriticum, Capillaria sp., and Taenia sp. eggs were identified, while some other objects similar to Anoplocephalidae and Toxocara spp. eggs were also retrieved from the samples but their measured parameters did not match those of these species. The present paper illustrates the first paleoparasitological findings of Bronze Age in eastern Iran supporting the economic activities, peopling, and communication as well as the appropriate condition for zoonotic helminthiasis life cycle in Shahr-e Sukhteh archeological site.

This study aimed to determine the prevalence of intestinal helminth parasitic infections and associated risk factors for the human infection among the people of Samarkand, Uzbekistan. Infection status of helminths including Echinococcus granulosus was surveyed in domestic and wild animals from 4 sites in the Samarkand region, Uzbekistan during 2015-2018. Fecal samples of each animal were examined with the formalin-ether sedimentation technique and the recovery of intestinal helminths was performed with naked eyes and a stereomicroscope in total 1,761 animals (1,755 dogs, 1 golden jackal, and 5 Corsac foxes). Total 658 adult worms of E. granulosus were detected in 28 (1.6%) dogs and 1 (100%) golden jackal. More than 6 species of helminths, i.e., Taenia hydatigena, Dipylidium caninum, Diplopylidium nolleri, Mesocestoides lineatus, Toxocara canis, and Trichuris vulpis, were found from 18 (1.0%) dogs. Six (T. hydatigena, Toxascaris leonina, Alaria alata, Uncinaria stenocephala, D. caninum, and M. lineatus) and 2 (D. nolleri and M. lineatus) species of helminths were also detected from 5 Corsac foxes and 1 golden jackal, respectively. Taeniid eggs were found in 2 (20%) out of 10 soil samples. In the present study, it was confirmed that the prevalences of helminths including E. granulosus are not so high in domestic and wild animals. Nevertheless, the awareness on the zoonotic helminth infections should be continuously maintained in Uzbekistan for the prevention of human infection.

Eosinophilic meningitis is defined as the presence of more than 10 eosinophils per µl in the cerebrospinal fluid (CSF), or eosinophils accounting for more than 10% of CSF leukocytes in patients with acute meningitis. Parasites are the most common cause of eosinophilic meningitis worldwide, but there is limited research on patients in Korea. Patients diagnosed with eosinophilic meningitis between January 2004 and June 2018 at a tertiary hospital in Seoul, Korea were retrospectively reviewed. The etiology and clinical characteristics of each patient were identified. Of the 22 patients included in the study, 11 (50%) had parasitic causes, of whom 8 (36%) were diagnosed as neurocysticercosis and 3 (14%) as Toxocara meningitis. Four (18%) patients were diagnosed with fungal meningitis, and underlying immunodeficiency was found in 2 of these patients. The etiology of another 4 (18%) patients was suspected to be tuberculosis, which is endemic in Korea. Viral and bacterial meningitis were relatively rare causes of eosinophilic meningitis, accounting for 2 (9%) and 1 (5%) patients, respectively. One patient with neurocysticercosis and 1 patient with fungal meningitis died, and 5 (23%) had neurologic sequelae. Parasite infections, especially neurocysticercosis and toxocariasis, were the most common cause of eosinophilic meningitis in Korean patients. Fungal meningitis, while relatively rare, is often aggressive and must be considered when searching for the cause of eosinophilic meningitis.

Antibody responses(IgG) to Paragonimus westermani. Clonorchis sinensis, Cysticercus cellulosae, Sparganum Anisakis simplex, Toxocara canis and Trichinella spiralis were studied. The ELISA technique was performed to determine the prevalence of above helminthic diseases. 975 cases obtained from Yanbian of China during October, 1995 to July, 1997 were examined with a positive antibody titer of 5.74% in clonorchiasis, 4.92% in paragonimiasis, 1.54% in cysticercosis. 8.51% in sparganosis, 1.85% in anisakiosis, 12.51% in toxocariasis, and 7.08% in trichinosis respectively. And 23.87% in showed positive antibody titer at least one of the seven helminths. The differences of the age and sex in the positive sera were analysed by the Chi-squared test and the level of significance accepted was p<0.05. The significant differences in positive antibody production were P.W.(p<0.01). C.S.(p<0.01), A.S.(p<0.05). T.C.(p<0.001), and T.S.(p<0.01) respectively in age groups. sparganosis(p<0.05) in sex groups. Other parasites showed that there were no significant differences among age groups and sex groups(males and females). Higher positive antibody rate of C.S. and P.W. occured in the 50-59 years old and those of T.C. and T.S. happened in the 20-29 years old. Patients of internal disease showed more positive antibody titer, that is to say, there was significant difference between positive rate of internal diseases and that of control (p<0.01. p<0.05) in 6 helminths except cysticercosis. The result showed that some cross reactions existed among nematodes, and the developed techniques(EITB) should be done for a correct diagnosis. Also the prevalence of some important helminths may be evaluated from the result and it would be a basic data for controlling parasitic diseases in Yanbian.
