A complementary DNA for human bcl-2 was cloned into the replication competent avian retrovirus vector RCASBP, and the resulting virus was used to express human Bcl-2 protein at high levels in chicken embryo fibroblasts. The expression of Bcl-2 did not transform or significantly alter the longevity of the chicken embryo fibroblasts in the presence of normal amounts of serum. However, the express...
The chorioallantoic membrane (CAM) inoculated chick embryo model was used to study the effect of host lineage on the virulence of Campylobacter jejuni and Campylobacter coli. LD50 values were used to compare the susceptibilities of chick embryos from eight inbred chicken lines to infection by four strains of C. jejuni and one strain of C. coli. Differences in susceptibility were found between i...
Tumor necrosis factor receptor-associated factor 3 (TRAF3) is a crucial regulator that suppresses c-Jun N-terminal kinase and non-canonical nuclear factor-kB signaling, but facilitates type I interferon production. To determine TRAF3 function in innate immune responses among birds, particularly chicken, we cloned and characterized the chicken TRAF3 gene (chTRAF3) and detected its tissue express...
The injection of chicken embryo, in amounts of from 1 to 10 cc., confers no resistance against the Rous chicken sarcoma, when this is inoculated from 5 to 100 days after the preliminary treatment.

Objective: In recent years, amino acids are used in veterinary medicine for many purposes. They injected into hatching eggs to increase chick body weight and performance at hatch, but the adverse effects of amino acids have always been a major concern. There is scant information available about the pathological alterations of amino acids in the chicken embryonated eggs. The objective of this st...
