An survey of antibodies to parvovirus was carried out in canines and felines. Three hundred and ninety six serum samples were collected from several domestic or wild canines and felines in different regions of China during 2009 to 2011. Sera from 203 canines samples and from 193 feline samples were tested for antibodies to canine parvovirus virus(CPV) and feline parvovirus virus(FPV) respectively using micro-hemagglutination inhibition(HI) and micro-serum neutralization assays(SN). The results of the two methods are highly parallel and consistent. The antibody positive rate to CPV is 28.6% in canines and 42.5% to FPV in felines. We propose that the canines and felines had been infected by parvovirus in different regions of China.

To explore the prevalence of the H5 subtype influenza A virus in captive tigers in China, the antibodies of 309 tigers' serum samples, which were collected from Harbin, Yichang, Guilin, Shanghai, Zhengzhou, and Tangshan between 1998 and 2009, were detected using the hemagglutination inhibition test ( HI). All 20 samples collected from April of 1998 to April of 2002 were HI antibody negative. Among 24 of 31 samples collected from July of 2002 to June of 2003 whose clinical signs such as fever and pneumonia were obvious, HI antibody were positive. Surprisingly, the antibody titers of paired sera from two tigers without clinical signs also were HI antibody positive. Of 220 samples randomly collected in 2004 in Harbin, 14 of 28 samples collected from tigers with clinical signs were HI antibody positive. In addition, we found that 43 samples collected from tigers without clinical signs also were positive with 1: 10 -1: 80 antibody titers. In 2009, only 3 out of 43 samples were HI antibody positive. These results indicate that H5 subtype influenza virus have already acquired the ability to infect tigers and pose a threat to captive tigers and public heath.
