Streptococcus iniae is a Gram-positive bacterium and a severe aquaculture pathogen that can infect a wide range of farmed fish species. In the summer of 2006, an epidemic broke out in a fish farm in north China, and examination of moribund fish (Japanese flounder) identified the possible etiological agent of the outbreak as a strain named SF1, which(More)
Vibrio harveyi is an important marine pathogen that can infect a number of aquaculture species. V. harveyi degQ (degQ(Vh)), the gene encoding a DegQ homologue, was cloned from T4, a pathogenic V. harveyi strain isolated from diseased fish. DegQ(Vh) was closely related to the HtrA family members identified in other Vibrio species and could complement the(More)
Edwardsiella tarda is a severe aquaculture pathogen that can infect many different fish species cultured worldwide. Et49 is a major E. tarda antigen with weak immunoprotective potential. In this study, using Et49 as an example vaccine, the adjuvanticity of Freund's incomplete adjuvant (FIA), aluminum hydroxide, and aluminum phosphate adjuvant were evaluated(More)
Post-weaning multi-systemic wasting syndrome (PMWS), which is primarily caused by porcine circovirus type 2 (PCV2), is an emerging swine immunosuppressive disease. To characterize the interaction between target immune cells and PCV2, the differential proteomes of porcine alveolar macrophages, with and without PCV2 infection, were analyzed at different time(More)
Porcine circovirus type 2 (PCV2) is the primary causative agent of porcine circovirus-associated diseases (PCVAD). It has been shown that the ubiquitin-proteasome system (UPS) is correlated with viral infection, but its role in PCV2 replication remains unknown. In the present study, we explored the interplay between PCV2 replication and the UPS in PK15(More)
Congenital human cytomegalovirus (HCMV) infection is a leading infectious cause of birth defects. Previous studies have reported birth defects with multiple organ maldevelopment in congenital HCMV-infected neonates. Multipotent mesenchymal stromal cells (MSCs) are a group of stem/progenitor cells that are multi-potent and can self-renew, and they play a(More)
Edwardsiella tarda is a Gram-negative bacterium that can infect a wide variety of marine and freshwater fish and cause severe economic losses worldwide. With an aim to elucidate the virulence mechanism of E. tarda, we in this study cloned and analyzed the function of an iron-cofactored superoxide dismutase (FeSOD) from a pathogenic E. tarda strain TX01(More)
The Haemophilus parasuis respiratory tract pathogen poses a severe threat to the swine industry despite available antimicrobial therapies. To gain a more detailed understanding of the molecular mechanisms underlying H. parasuis response to tilmicosin treatment, microarray technology was applied to analyze the variation in gene expression of isolated H.(More)
Three new salicylidene Schiff base nickel(II) complexes [Ni(L(1))(CH3COOH)2]2 (1), [Ni2(L(1))2(CH3OH)] (2), [Ni(L(2))2]·3H2O (3) {H2L(1)=N,N'-bis(salicylidene)-3,6-dioxa-1,8-diaminooctane, HL(2)=2-ethyl-2-(2-hydroxybenzylideneamino)propane-1,3-diol} were synthesized and characterized fully by structural, analytical, and spectral methods. The single-crystal(More)
OBJECTIVE To observe the effects of fruit juices with different antioxidant capacity on antioxidant system function of aged rats. METHODS Thirty Wistar rats were randomly divided into three groups: pomegranate juice and apple juice as two experimental groups, while distilled water as normal control group. They were administrated fruit juices or distilled(More)
