Vector-borne arboviruses produce mild to severe symptoms in domestic animals. Bovine ephemeral fever (BEF), Akabane, Aino, and Chuzan virus have been primarily attributed to reproductive disorders or febrile diseases in cattle, and Japanese encephalitis virus (JEV) is mainly associated with reproductive failures in swine. We investigated antibody titers(More)
Since the prevalence of bovine norovirus (BNoV) and their genetic diversity have only been reported in the USA, England, Germany and The Netherlands, this study examined the prevalence and genetic diversity of BNoVs in diarrheic calves in South Korea using 645 diarrheic fecal specimens from calves by RT-PCR and nested PCR assays. Overall, 9.3% of the(More)
Recent global warming trends may have a significant impact on vector-borne viral diseases, possibly affecting vector population dynamics and disease transmission. This study measured levels of hemagglutination-inhibition (HI) antibodies against Japanese encephalitis virus (JEV) and neutralizing antibodies against Akabane virus (AKAV) and Aino virus (AINV)(More)
A total of 804 goat sera were collected from 144 goat farms in five regions of South Korea during a period between 2005 and 2006 and screened for the antibodies of viral pathogens in ruminants. The individual seropositive rates for each virus were 13.7% (110/804) for bovine herpesvirus-1 (BHV-1), 9.5% (76/804) for bovine parainfluenza type-3 virus (PI-3V),(More)
Group A rotaviruses (GARVs) cause severe acute gastroenteritis in children and young animals. Although zoonotic infections with bovine-like G6 and G8 GARVs have been reported in many countries, there is little evidence for reassortment between bovine GARVs and GARVs from heterologous species. The finding of bovine GARVs with the G6 and G8 genotypes in(More)
One step TaqMan reverse transcription polymerase chain reaction (RT-PCR) using TaqMan probe was developed for detection of Japanese encephalitis virus (JEV). Real-time RT-PCR was optimized to quantify JEV using the detection system (Rotor Gene 2000 detector) and dual-labeled fluorogenic probes. The gene specific labeled fluorogenic probe for the 3'(More)
We have determined the complete nucleotide and deduced amino acid sequences of the Japanese encephalitis virus (JEV) strain KV1899, isolated from a fattening pig in Korea. In comparison with 22 fully sequenced JEV genomes currently available, we found that the 10,963-nucleotide RNA genome of KV1899 has a 13-nucleotide deletion in the 3' non-translated(More)
Aino, Akabane and Chuzan viruses are arthropod-borne (arbo) viruses transmitted by blood-sucking insects like mosquitoes and Culicoides biting midges. These arbovirus infections are mainly associated with abortion, stillbirth and congenital defects in pregnant cattle, sheep and goats, which induces a considerable economic loss in livestock industry. The(More)
The Japanese encephalitis virus (JEV) is one of causative agents of reproductive failure in pregnant sows. An indirect enzyme-linked immunosorbent assay (I-ELISA) was examined for its potential use in the rapid monitoring of the JEV, and the results were compared with those from the hemagglutination inhibition (HI) and serum neutralization (SN) tests. The(More)
Group A rotaviruses (RVAs) are agents causing severe gastroenteritis in infants and young animals. G9 RVA strains are believed to have originated from pigs. However, this genotype has emerged as the fifth major human RVA genotype worldwide. To better understand the relationship between human and porcine RVA strains, complete RVA genome data are needed.
