First report of a ranavirus associated with morbidity and mortality in farmed Chinese giant salamanders (Andrias davidianus).
The virus, provisionally designated as Chinese giant salamander virus (CGSV), was isolated from tissue homogenates of diseased salamanders following inoculation of epithelioma papilloma cyprini cells and Sequence analysis of the MCP genes showed that the isolated virus was a ranavirus with marked sequence identity to other members of the genus Ranavirus.

This is the first report of S. agalactiae as a pathogen of ya-fish, and the virulence tests were conducted by intraperitoneal injection of the isolated strain GY101 in ya- fish, crucian carp and the Nile tilapia.
Multilocus genotypes and broad host-range of Enterocytozoon bieneusi in captive wildlife at zoological gardens in China
The occurrence of zoonotic genotypes suggests that wildlife may act as reservoirs of E. bieneusi that can serve as a source of human microsporidiosis, and the findings presented here should contribute to the control ofZoonotic disease in China.
The pathology of selenium deficiency in Cyprinus carpio L.
The results indicated that the morbidity and mortality rates of the test groups were negatively correlated with the level of selenium in the diets.
Outbreaks of vibriosis associated with Vibrio mimicus in freshwater catfish in China
The results of this investigation indicate that V. mimicus was the causative agent of the natural epizootic in freshwater catfish and is the first report of Vibrio mimicus infection associated with mass mortality in freshwaterCatfish.
Safety and immunogenicity of an oral DNA vaccine encoding Sip of Streptococcus agalactiae from Nile tilapia Oreochromis niloticus delivered by live attenuated Salmonella typhimurium.
The DNA vaccine SL/pVAX1-sip was proved to be safe and effective in protecting tilapias against S. agalactiae infection and remained stable over 80% during 35 generations under antibiotic-free conditions.
Stenotrophomonas maltophilia, an emerging opportunist pathogen for cultured channel catfish, Ictalurus punctatus, in China
This is the first report of S. maltophilia as a pathogen of channel catfish and the strains showed a similar antibiotic susceptibility, which was characterized by resistance to all penicillins, cephalosporins, and aminoglycosides and to ambramycin, erythromycin, and rifampicin.
Isolation and characterization of Streptococcus agalactiae from Nile Tilapia Oreochromis niloticus in China
Characteristics based on morphological, physiological and biochemical tests show that the eight strains isolated from the outbreak epidemical diseased tilapias from Hainan Province, China were suggested to Streptococcus agalactiae, which hinted that the species had become an important potential bacterial agent of tilapia in the south of China.
A recombinant truncated surface immunogenic protein (tSip) plus adjuvant FIA confers active protection against Group B streptococcus infection in tilapia.
It was revealed that tSip mixed with FIA was an effective vaccine against GBS in tilapia, while AH is toxic totilapia.
First Isolation of New Canine Parvovirus 2a from Tibetan Mastiff and Global Analysis of the Full-Length VP2 Gene of Canine Parvoviruses 2 in China
This study is the first to isolate new CPV-2a from the Tibetan mastiff and performs a global analysis of the complete VP2 gene sequences of CPv-2 strains in China, indicating the high diversity of CPVs in China.
