In the absence of infectious subgroup E avian leukosis-sarcoma (ALS) viruses, some chicken embryo cells contain in their cell membrane the envelope glycoprotein of subgroup E viruses (gpE) (Hanafusa et al. 1973). The partial expression of subgroup E virus was first recognized as chick-cell-associated helper factor (chfl, which provided the helper function for the envelope-defective Bryan high-t...
Ornithobacterium rhinotracheale was found to cause growth retardation in both turkeys and chickens after experimental intra-air sac administration and to cause growth retardation together with airsacculitis and pneumonia after aerosol administration. Both turkey and chicken isolates of O. rhinotracheale were able to induce the same kind of respiratory inflammations and weight-gain losses in chi...
Vaccinia virus (VACV) has been associated with several bovine vaccinia outbreaks in Brazil, affecting cattle and humans. There are no available data about VACV environmental circulation or the role of wildlife in the emergence of an outbreak. Since VACV was isolated from rodents in Brazil, we investigated shedding and transmission of VACV strains in mice. The VACV excretion profile was assessed...
Complete genome sequence analysis of a natural reassortant infectious bursal disease virus in China.
A novel isolate of infectious bursal disease virus (IBDV) was designated GX-NN-L. The GX-NN-L IBDV was a very virulent infectious bursal disease virus (vvIBDV) isolated from broiler flocks in Guangxi province, China, in 2011. The GX-NN-L IBDV caused high mortality, immunosuppression, low weight gain, and bursal atrophy in commercial broilers. Here, we report the complete genome sequence of the ...
