The effects of methanolic extract and leaf powder of Artemisia annua were studied on performance, cellular and humoral immunity in 240 Cobb broiler chicks in a completely randomized design. Control group did not receive any treatment. The chicks in the second and third groups were fed with feed which contained 2000 and 4000 ppm plant extract in diet and in the groups 4, 5 and 6 chicks received ...

Growth Response and Humoral Immunity of Broiler Chickens Fed Organic Acids Zeolite Coated with Silver Nanoparticles under Heat Stress Conditions

vaccines against the hiv-1 virus offers the best hope for eliminating hiv-associated mortality. recombinant adenovector type 5 (rad5) vaccine is a potential candidate for preventive vaccine strategies. in this study, we evaluated the rad5 prime/protein boost strategy in a murine model. we used rad5 harboring single hiv-1 genes. these genes, including gag (p24) and exon1 of tat, were amplified f...

Sera from patients with heart disease were examined by single sandwich indirect immunofluorescence for the presence of antibodies to human heart muscle. Endocardial biopsy specimens were also examined by direct immunofluorescence for deposition of antibodies in vivo. No consistent or specific abnormality was found in the biopsy specimens or sera of patients with congestive cardiomyopathy. The p...

Immunity to reinfection in the genital tract of female guinea pigs with the agent of guinea pig inclusion conjunctivitis was found to be dependent upon an intact humoral immune response. Cell-mediated immunity in the absence of humoral immunity had no apparent role in resistance to challenge infection.
