Growth of Newcastle disease virus and rubella virus in rheumatoid and nonrehumatoid synovial cell cultures.

Immune response of chickens to four lentogenic strains of Newcastle disease virus propagated in lamb kidney cell cultures

Comparison of pathogenicity and immunogenicity of two strains (TCND and Montana) of Newcastle disease virus propagated in four tissue cell types

Investigating of the methods used to find external agents in vaccines and biological products

multiple technological levels the necessity of developing vaccine quality control systems is one of the requirements of our  country Coordinated tests of the absence of externous agents in biological substances are considered as a major international concern for veterinary vaccines. Exogenous agents such as Newcastle disease virus, avian leukosis virus, infectious laryngotracheitis virus (ILTV)...

Rubella virus and rheumatoid arthritis.

A collection of synovial fibroblasts from 19 patients with rheumatoid arthritis (RA) and 12 patients with osteoarthrosis or other non-RA disease has been examined for rubella virus antigens by immunofluorescence and radioimmunoassay with negative results. Eluates of synovial membrane prepared under conditions likely to dissociate antigen-antibody complexes have shown no rubella antibody. A sero...

Effect of in ovo Injection of Royal Jelly on Post-Hatch Growth Performance and Immune Response in Broiler Chickens Challenged with Newcastle Disease Virus

The aim of this experiment was to study the effect of in ovoinjection of royal jelly (RJ) on growth performance and immune response in broiler chickens challenged with Newcastle disease virus. A total of 200 hatching eggs were divided into four groups of 50 eggs each one using a completely randomized design. The eggs were injected with sterilized sodium bicarbonate buffer (pH=10.4) or RJ (88%) ...
