Replication and transmission of avian influenza virus (AIV) in domestic dogs and cats may pose a risk to humans. The susceptibility of cats and dogs to H9N2 influenza virus was evaluated by intranasally or orally inoculating animals with an H9N2 influenza virus. Cats had recoverable virus in respiratory tissues and the olfactory bulb three days(More)
Kobuviruses comprise three species, the Aichivirus A, Aichivirus B, and Aichivirus C (porcine kobuvirus). Porcine kobuvirus is endemic to pig farms and is not restricted geographically but, rather, is distributed worldwide. The complete genomic sequences of four porcine kobuvirus strains isolated during a diarrhea outbreak in piglets in the Gansu province(More)
The lung fluke, Paragonimus westermani, is of major socioeconomic importance in Asia. The parasite is transmitted via snails to freshwater crabs or crayfish, then to humans and other mammals, such as cats and dogs, and causes paragonimiasis. This review provides a background on the parasite and its life cycle; summarizes key aspects regarding the(More)
Newcastle disease virus (NDV) has only a single serotype but diversified genotypes. Genotype VII strains are the prevalent currently circulating genotype worldwide, and in particular, these strains cause outbreaks in waterfowl. In this study, a reverse genetics system for highly virulent NDV isolated from goose flocks was developed independent of(More)
Fatal Ebola virus infection is characterized by a systemic inflammatory response similar to septic shock. Ebola glycoprotein (GP) is involved in this process through activating dendritic cells (DCs) and macrophages. However, the mechanism is unclear. Here, we showed that LSECtin (also known as CLEC4G) plays an important role in GP-mediated inflammatory(More)
Sequences of the full-length gene encoding the main capsid protein VP2 of 22 strains of canine parvovirus (CPV), isolated from domestic dogs in China between 1983 and 2008, were determined and analyzed in comparison with the sequences of 30 other strains of CPV from China and reference CPV isolates retrieved from GenBank. Three types of CPV, including(More)
H7 avian influenza viruses (AIVs) have caused a number of human infections, highlighting the pandemic potential of them. However, the factors that promote their replication in mammals remain poorly understood. Here, we generated mouse-adapted variants of a reassortant H7N1 virus to identify adaptive changes that confer enhanced virulence in mammals. The(More)
Effective, safe, and affordable rabies vaccines are still being sought. Newcastle disease virus (NDV), an avian paramyxovirus, has shown promise as a vaccine vector for mammals. Here, we generated a recombinant avirulent NDV La Sota strain expressing the rabies virus glycoprotein (RVG) and evaluated its potential to serve as a vaccine against rabies. The(More)
Between January 2012 and March 2012, the infection rates of porcine epidemic diarrhea virus (PEDV) increased substantially in vaccinated swine herds in many porcine farms in Gansu Province, China. The spike (S) glycoprotein is an important determinant for PEDV biological properties. To determine the distribution profile of PEDV outbreak strains, we(More)
H6N1 avian influenza viruses (AIVs) may pose a potential human risk as suggested by the first documented naturally-acquired human H6N1 virus infection in 2013. Here, we set out to elucidate viral determinants critical to the pathogenesis of this virus using a mouse model. We found that the recombinant H6N1 viruses possessing both the PA-T97I and PB2-E627K(More)
