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.

Wildlife has been recognized that has important role as reservoir hosts of disease affecting both people and livestocks. However, information intestinal helminths of Korean water deer were limited. We obtained 20 feces from Korean water deers that were transferred to veterinary hospital in Chungbuk National University from May 2010 to June 2011. Parasite ova were collected using saturated zinc sulfate floatation method. Parasite eggs were examined and measured using light microscope. The identification of parasitic eggs was done by morphological characters. The overall infection rate of parasite was 85% (n=17). The eggs were observed as being Nematodirus spp. (n=14), strongyles egg (n=11), Capillaria spp. (n=9), Trichuris spp. (n=7), Eimeria spp. (n=4), Ogmocotyle spp. (n=3), and Strongyloides (n=1). Mixed infection rate was observed as being single 15% (n=3), double 20% (n=3), triple 15% (n=3), quadruple 30% (n=6), and quintuple 5% (n=1). The Ogmocotyle spp. was first reported in Korea.

This report was undertaken to examine the correlationship between internal parasite infection and amount of milk production before and after vermicidal administration on F. hepatica and gastrointestinal nematoda infected cattle. The obtained results were as follows ; 1. Out of total number(358), the ratios of parasitic infected catle were 43.5%(156). Among them milking cattl. and Korean native cattle were 52.7% and 31.6%, respectively. 2. In this examination, 10 kinds of parasites were detected. Among them F. hepatica was encountered most frquently and also Buxtonella, Paramphistoma, Coccidim, Cestoda, and Trichur were encountered in order. 3. The average increased amount of milk production after vermicidal administration on F. hepatica and gastrointestinal nematoda infected cattle was 1.1Kg per day.

To determine association of grassland with parasitic diseases of livestock in Bangladesh, the 'Tracer' animals (two cow calves and two goats) were released for a month in a grassland used for communal grazing of livestock near school premise in Kanthal, Trishal, Mymensingh, Bangladesh. After slaughtering of the tracer animals, their gastrointestinal tract examination revealed six species of nematode and one cestode. The nematode species were Haemonchus contortus, Trichostrongylus axei, Mecistocirrus digitatus, Oesophagostomum spp., Trichuris spp. and Bunostomum sp. The cestode was one of the genus Moniezia. With this preliminary study, grasslands are thought to be one of the main sources of gastrointestinal parasitic diseases of livestock in Bangladesh.

Paleoparasitological analysis was carried on 4 Merovingian skeletons, dated from the late-5th to the late-9th centuries, and recovered in the church of Saint-Martin-au-Val in Chartres (Center region, France). The corpses were buried in stone sarcophagi, which were still sealed at the time of excavation. Parasite marker extraction was conducted on sediment samples taken from the abdominal and pelvic regions, but also on samples taken from under the head and the feet as control samples. Microscopic observation revealed the presence of 3 gastrointestinal parasites, namely the roundworm (Ascaris lumbricoides), the whipworm (Trichuris trichiura) and the fish tapeworm (genus Diphyllobothrium). This analysis contributes to a better knowledge of the health status and the lifestyle of ancient medieval populations during the Merovingian period, for which very few paleoparasitological data were available, up until now. It demonstrates the presence of the fish tapeworm for the first time during this period.

This study aimed to examine the distribution of gastrointestinal parasitic infections in domestic pigs in the Republic of Korea. From May 2020 to October 2021, 364 pig fecal samples were collected from 75 farms in 7 Provinces and microscopically examined. A total of 170 (46.7%) pigs were infected with at least one of the following parasites: Balantioides coli, strongyles, Ascaris suum, Trichuris suis, and coccidia. By parasite species, B. coli, strongyles, A. suum, T. suis, and coccidia oocysts or eggs were detected in 144 (39.6%), 24 (6.6%), 14 (3.8%), 4 (1.1%), and 1 (0.3%) samples, respectively. One hundred fifty-four, 15, and 1 cases showed single, double, and triple infections, respectively. Of the swine fecal samples from 75 farms, 69 specimens (92.0%) were infected with 1 or more parasites. All surveyed farms across the country exhibited a positive rate of over 30%, among which the highest positive rate was 65.0% in Chungcheongnamdo, and Jeollabuk-do was followed by 61.9%. Winter showed a statistically lower prevalence than other seasons. This study showed that gastrointestinal parasites are prevalent in pigs in Korea, although the diversity of parasites is low.

This study reports the first two clinical cases of spirometrosis caused by Spirometra sp. in cats in Korea. In these two cases, the cats vomited, and long proglottids of tapeworm were recovered. The sick cats presented with anorexia and lethargy. However, they unexpectedly showed no diarrhea, which is the main symptom of spirometrosis. Based on a fecal floatation test as well as morphological and molecular analyses, the parasite was diagnosed as Spirometra sp. The 2 cases were treated with praziquantel. This study suggests regular monitoring of health and deworming in companion animals, even when animals are well cared for, with regular preventive medication. Additionally, spirometrosis should be considered in the differential diagnosis in cases of gastrointestinal symptoms in Spirometra endemic areas.

Cryposporidium species have a wide host range. These coccidian parasites are found in close association with epithelial cells of many species of animals including mm. The gastrointestinal tract is most commonly affected in young ruminants and this parasite is thought to be considerable importance in calf diarrhea complex. Major outbreaks of cryptosporidiosis have been reported in calves, lambs, pigs and others including avian species. Cryptosporidiosis is transmitted by oocysts of Cryptosporidium species. Because cryptosporidiosis is common infection among animals, early literature considered it a zoonosis. Human infections contracted from calves, cats, and horse feces. However, the resrvoir host is longer considered the major source of infection. Mild cases of disease have been reported in farm workers. Immunosuppressed, very young and very old persons should avoid contact with this parasite because it may cause severe diarrhea. In order to detect of Crytosporidium sp infection from feces of cattle and pigs at Chonbuk Iksan and Kunsan area, sedimentation and modified acid fast stain were applied. The positive rate of Cryptosporidium sp infection from 1, 176 of cattle and 267 of pigs were 0.5 % and 16.8%, respectively. According to area in Iksan and Kunsan, the positive rates were 0.4% and 0.9% from cattle, and 18.9% and 12.1% from pigs, respectively. In cattle, positive detection rate was 0.6% in milking cows but not in Korean cattle.

Helicobacter pylori infection plays an important role in the pathogenesis of chronic gastritis, peptic ulcer disease and gastric malignancy. A diagnosis of infection is thus an important part of a treatment strategy of many gastrointestinal tract diseases. Many diagnostic tests are available but all have some limitations in different clinical situations and laboratory settings. A single gold standard cannot available, but be used for diagnosis of Helicobacter pylori infection in daily clinical practice in all areas, so several techniques have been developed to give reliable results, especially focusing on real time endoscopic features. The narrow band imaging system (NBI) and high resolution endoscopy are imaging techniques for enhanced visualization of infected mucosa and premalignant gastric lesions. The aim of this article is to review the current diagnostic options and possible future developments detection of Helicobacter pylori infection.
