“…This study included horses reared throughout Korea. Korea is located between 34°20' to 37°11' northern latitude and 126°07'-129°19' eastern longitude (Jung et al 2014). The study area has an annual precipitation of 1300 mm and an annual mean temperature of 12.9 °C (cold season mean: -2.1 °C, warm season mean: 27.3 °C).…”

ABSTRACT:The objective of this study was to investigate the nationwide prevalence of Anaplasma phagocytophilum in horses reared in Korea using a commercial ELISA kit and two different nested PCR (nPCR) analyses. Our analysis showed that 2.9% (true prevalence: 3.1%, 16/549) of the horses were seropositive by ELISA, and none were positive by the two nPCR analyses. Significant differences were observed in the ELISA results when the data were analysed according to breed and geographic region. In light of a recent case of human granulocytic anaplasmosis in Korea and the predicted increase in the number and distribution of ticks due to global warming, continuous monitoring and appropriate control programs for Anaplasma spp. and other tick-borne pathogens need to be established.

“…In previous studies, the relationship between the disease and various risk factors was examined, and conflicting results were obtained. In some studies, the age, breed, presence of dogs in flocks, and season are presented as risk factors important for the prevalence of neosporosis, which is not confirmed by some other studies (1,2,6,8,13,14,16,22,26,34,37,39,41). As a general consensus, the sex of the animals is thought to have no effect on the prevalence of the disease (6,12,(14)(15)(16).…”

Neospora caninum is a parasitic protozoan that causes abortion, stillbirth, and premature culling in goats. The aims of this study were (i) to determine the prevalence of anti-N. caninum antibodies in goats in the Adana province of Turkey(ii), to identify risk factors for the disease, and (iii) to provide collective data on goat neosporosis. For this purpose, 383 sera were collected from goats of different breeds, ages, and sexes from 15 counties of Adana. A commercially available c-ELISA test kit was used to detect anti-N. caninum antibodies. To identify risk factors that influence the prevalence of neosporosis, an oral survey was conducted, and the data collected were evaluated by the logistic regression analysis. The prevalence was determined as 8.9% (34/383) at the individual level and 66.6% (10/15) at the flock level. Statistical analysis indicated that the co-presence of sheep, the animals’ being of pure breed and the purchasing of animals from different flocks are the factors that increase the prevalence of neosporosis, while feeder disinfection decreases it.

We assessed the prevalence and performed molecular analysis of Cryptosporidium spp. in diarrheal feces of calves in Korea. Diarrheal fecal samples were collected from 951 young calves (<3months) on 425 farms. Cryptosporidium prevalence was assessed by PCR and ELISA, and molecular characterization was performed by targeting the 18S rRNA, heat-shock protein 70 (hsp70), and glycoprotein 60 (gp60) genes. Data were analyzed according to the sex, type of cattle, region, season, and type of diarrhea. PCR analysis revealed Cryptosporidium spp. in 9.9% (94/951) of diarrheal fecal samples. C. parvum and C. bovis/ryanae were present in 6.1% (58/951) and 4.1% (39/951) of diarrheal fecal samples, respectively. In addition, ELISA showed positive results for C. parvum in 9.7% (92/951) samples. Statistical analysis of the PCR and ELISA results revealed a lower prevalence of C. parvum in the hemorrhagic diarrheal samples (P<0.05). For C. bovis/ryanae, seasonality and high prevalence in hemorrhagic diarrhea were observed (P<0.05). Of the 951 samples tested for C. parvum, 903 samples showed agreement with a κ value of 0.65, indicating good agreement between the two tests. Although C. bovis and C. ryanae share highly similar 18S rRNA sequences, PCR based on hsp70 successfully distinguished C. bovis from C. ryanae. Sequence analysis of gp60 revealed that C. parvum belonged to the IIa families and was further subtyped as IIaA18G3R1 and IIaA16G3R1, which have not been previously reported in Asia. These findings indicate that Cryptosporidium spp. play an important role in diarrhea in young calves in Korea. Considering the zoonotic significance of C. parvum IIa subtype and dense rearing system of cattle in Korea, prevention and continuous monitoring of Cryptosporidium are required.
