Background & Objectives: Cyclophosphamide is an alkylating agent that stops the replication of DNA, which is used to treat various types of cancer and some autoimmune disorders. This study was aimed at then evaluating the immunomodulating effect of cyclophosphamide (Cy) on the immune system of vaccinated and non-vaccinated mice.Materials & Methods: The study was performed on three groups of mi...
bovine tropical theileriosis caused by theileria annulata is an economically important disease of cattle. an enzyme linked immunosorbent assay (elisa) was used to determine antibody levels in vaccinated and unvaccinated cattle, us¬ing cellular schizont as antigen and its results were compared with immunofluo-rescent assay (ifa). for this test 126 sera collected (105 vaccinated, 31 not vacci¬nat...
White spot syndrome virus (WSSV) is the causative agent responsible for huge-shrimp viral epidemics in shrimp farms throughout the world. Our study was aimed to determine the effect of WSSV Gamma-vaccinated Litopenaeus vannamei on the occurrence of apoptosis. One thousand and twenty PL15 were randomly distributed among 2 treatments and two control groups. Gama-Vaccinated shrimp and non-Gamma-va...
Background: The analysis of antigen-specific cytokine expression has been considered to evaluate the immune responses and vaccines efficacy in recent years. The aim of this study was to compare the cell-mediated immune response characteristics of two Capri pox virus (CaPV) vaccines against lumpy skin disease in cattle. Materials and Methods: Two Capri pox virus vaccines were administered to da...
A study has been carried out for determining of cross-immunity between Massachusetts (Mass) M41 and Iranian IR/773/2001 (793/B) strains of infectious bronchitis virus. Two groups of 20 three weeks old SPF chickens vaccinated subcutaneously with two oil-emulsions inactivated Infectious Bronchitis Vaccines (Mass M41 and Iranian IR/773/2001 strains) that had been manufactured in Razi institute in ...
