The potential role of the mast cells in the invasion of very virulent infectious bursal disease virus (vvIBDV) is unknown. We evaluated mast cell activity and tryptase production after vvIBDV infection in special pathogen-free (SPF) chickens using cytochemistry and immunohistochemistry analyses. The results were as follows: (1) severe histologic lesions(More)
Recent studies here have demonstrated that increased mast cell populations and tryptase activity contribute to lesion formation in regions of immune organs in special-pathogen-free chickens after infection with very virulent infectious bursal disease virus (vvIBDV). Mast cells and their mediators have been implicated in acute inflammatory injury after(More)
Methyl 5-aminosalicylate hydrochloride (M-5-AS) at the dosages of 21, 42, 209, and 417 mg.kg-1.d-1 ig to mice during d 6-15 of pregnancy, no obvious effects on the placenta, fetus weight, sex differentiation, external appearance, visceral, and skeletal development were observed. In rats ig M-5-AS 56 and 556 mg.kg-1.d-1 produced no noticeable effects on the(More)
The use of avian herpesviruses (Marek's disease virus, MDV) as vectors to express the capsid protein of infectious bursal disease virus (IBDV) was well established, and its protection against IBDV challenge has been evaluated previously. However, there is little data about rMDV1 expressing the VP2 protein of IBDV protecting SPF and commercial chickens(More)
