Bats are natural hosts for a large variety of zoonotic viruses. This study aimed to describe the range of bat viromes, including viruses from mammals, insects, fungi, plants, and phages, in 11 insectivorous bat species (216 bats in total) common in six provinces of China. To analyze viromes, we used sequence-independent PCR amplification and next-generation(More)

RATIONALE AND OBJECTIVE The acute respiratory distress syndrome (ARDS) caused by avian influenza H5N1 viral infection has been reported in many humans since this virus was found to infect humans in Hong Kong in 1997, but no studies regarding an animal model of ARDS with H5N1 viral infection have been found in the literature. Here we present a mouse model of(More)
Studies have demonstrated that ~60%-80% of emerging infectious diseases (EIDs) in humans originated from wild life. Bats are natural reservoirs of a large variety of viruses, including many important zoonotic viruses that cause severe diseases in humans and domestic animals. However, the understanding of the viral population and the ecological diversity(More)
Leptin, a 16-kDa hormone produced by mature adipocytes, has been shown to regulate the hibernation of mammals. In this study, the leptin gene sequences of both hibernating (Rhinolophus ferrumequinum) and non-hibernating (Rousettus leschenaultii) bats were determined, and the leptin proteins from these two different species of bats were expressed in(More)
In 2012 a large outbreak of hand, foot, and mouth disease (HFMD) widely spread over China, causing more than 2 million cases and 567 deaths. Our purpose was to characterize the major pathogens responsible for the 2012 HFMD outbreak and analyze the genetic characterization of the enterovirus 71 (EV71) strains in Shanghai; also, to analyze the dynamic(More)
We tested the amantadine-resistance among avian influenza A (H5N1) viruses isolated from chicken in Hebei Province of Northern China from 2001 to 2005, and investigated the amantadine use in this area. Plague reduction assay in MDCK cells showed that 83.3% isolates (5/6) were amantadine-resistant strains. The M2 sequence analysis revealed that four of five(More)
BACKGROUND Acute lung injury is an important cause of death in humans infected with H5N1. It has been found that oxygen free radicals (OFRs) are elevated in lung tissue during influenza virus infections. In this study, we used a mouse model to explore the role of OFRs in acute lung injury caused by H5N1 viral infection. METHODS Four- to six-week-old male(More)
Wild birds are considered to be the natural reservoirs for avian influenza A viruses (AIV). During active influenza surveillance in Poyang Lake of southeast China, we isolated and characterized 11 H9N2 viruses from two species of wild ducks. Phylogenetic analysis showed that the 11 isolates were almost identical with 99.3-100% nucleotide homology in their(More)
BACKGROUND Inflammatory process results in lung injury that may lead to pulmonary fibrosis (PF). Here, we described PF in mice infected with H5N1 virus. METHODS Eight-week-old BALB/c mice were inoculated intranasally with 1 x 101 MID50 of A/Chicken/Hebei/108/2002(H5N1) viruses. Lung injury/fibrosis was evaluated by observation of hydroxyproline(More)
