Rapid, low-cost, and user-friendly strategies are urgently needed for early disease diagnosis and timely treatment, particularly for on-site screening of pathogens in aquaculture. In this study, we successfully developed a real-time fluorogenic loop-mediated isothermal amplification assay integrated on a microfluidic disc chip (on-chip LAMP), which was(More)
Ginsenoside, the most important component isolated from Panax ginseng, exhibits a variety of biological activities. Particularly, ginsenoside Rg1 is known to have immune-modulating activities such as increase of immune activity of T helper (Th) cells. In the present study, we evaluated the immunomodulatory potentials of the Rg1 at three dose levels on the(More)
Seroprevalence of Toxoplasma gondii infection in pigs in 10 regions of Zhejiang Province, China, was obtained by enzyme-linked immunosorbent assay (ELISA). Anti- T. gondii antibodies were found in 53.4% (434/813) of pigs. Results were analyzed by a chi-square (χ(2)) test. Differences were observed according to farm size, animal age, and sampling regions.(More)
There are many methods available for printer identification of questioned documents, however most of them need identical contents of the training and testing documents. There is no effective method yet when the contents of the training and testing documents are different. To overcome this obstacle a method based on synthetic texture analysis is proposed in(More)
Meloidogyne mali Itoh, Ohshima & Ichinohe, 1969 is a polyphagous root-knot nematode that infects a wide range of host plants and is subject to phytosanitary restrictions in many countries, including China. In this study, we integrated the loop-mediated isothermal amplification (LAMP) technique with visual detection by a lateral flow dipstick (LFD) and(More)
An experiment was conducted to study the adjuvant effect of ginsomes on the recombinant profilin in coccidian-infected breeding birds. Three-day-old chickens were vaccinated with Eimeria tenella recombinant profilin antigen (10, 50, and 100 μg per chicken) with or without 50 μg ginsomes per chicken. The boost vaccination was carried out 14 days later. Two(More)
Aminopeptidase H11, an integral membrane glycoprotein present only in the gut of Haemonchus contortus, could provide substantial protection as shown by 90% reduction in fecal egg counts, while its recombinant version expressed in E. coli induced little. To investigate the characteristics further, we amplified mRNA of H11 gene via reverse transcriptase(More)
Haemonchus contortus is a common bloodsucking nematode causing widespread economic loss in agriculture. Upon H. contortus infection, a series of host responses is elicited, especially those related to T lymphocyte immunity. Existing studies mainly focus on the general immune responses of sheep T lymphocyte to H. contortus, lacking investigations at the(More)
Halofuginone (stenorol) has been used as an effective anticoccidial reagent for decades but very little is known about its mode of action. In this study, chickens were inoculated with Eimeria tenella oocysts on 14-day-old and medicated with halofuginone at days 0, 1, 2, 3, 4, 5 and 6 post inoculations (groups 0, 1, 2, 3, 4, 5 and 6, respectively). Chickens(More)
