ABSTRACT: Reports of dogs with H3N2 canine influenza virus (CIV) have been documented frequently. To better understand the seroprevalence of H3N2 CIV among dogs in northeast China, here we report for the first time a relatively high seroprevalence of H3N2 CIV infection in dogs in northeast China. Forty-five of the 223 canine sera (20.2%) and 166 of the 500 canine sera (33.2%) tested feral dogs and pet dogs were seropositive by NP-ELISA, which is higher than that in southern China. The relative data provided in this report can be useful for small animal practitioners or public health policy makers to carry out relative measures for the prevention of this disease. Meanwhile similar seroprevalence studies and prospective natural history and incidence studies should also be undertaken in other places.

ABSTRACT: Infection of domestic cats with pandemic (H1N1) 2009 has recently been documented. In this study, we report for the first time the sporadically current seroprevalence of influenza A (H1N1) pdm09 infection in cats in China. Thirteen (13/1080) sera were found positive by NP-specific ELISA in different cat populations in southern China. It is very important to stress further surveillance of the pandemic (H1N1) 2009 in cats in southern China.

ABSTRACT: We report here the complete genomic sequence of a novel porcine circovirus type 2 (PCV2) strain, which is supposed to be the result of natural genetic recombination between the ORF1 gene of genotype PCV2b-1B and the ORF2 gene of PCV2b-1C. Further analyses revealed that this novel PCV2 strain arose from recombination between PCV2a and PCV2b strains within the ORF2 gene. To our knowledge, this is the first report of both inter- and intragenotype PCV2 gene rearrangement in the field, and it will help in understanding the epidemiology and molecular characteristics of porcine circovirus type 2(PCV2) in southern China.

ABSTRACT: We report here the complete genomic sequence of a novel avian-like H3N2 swine influenza virus containing an H5N1 highly pathogenic avian influenza virus segment that was obtained from swine in southern China. Phylogenetic analysis indicated that this virus might originate from domestic aquatic birds. The sequence information provided herein suggests that continuing study is required to determine if this virus can be established in the swine population and pose potential threats to public health.

ABSTRACT: We report here the complete genomic sequence of a novel duck hepatitis A virus (DHAV) isolated from mixed infections with DHAV type 1 (DHAV-1) and DHAV-3 in ducklings in Southern China. The whole nucleotide sequence had the highest homology with the sequence of DHAV-3 (GenBank accession number DQ812093) (96.2%). To our knowledge, this is the first report of gene rearrangement between DHAV-1 and DHAV-3, and it will help to understand the epidemiology and molecular characteristics of duck hepatitis A virus in Southern China.
