چکیده

Aflatoxin G2 was used to test the speed and accuracy of the microapplicator and the micropipette. The 50% lethal dose of both assay systems was approximately the same, and 4.0 mug of G2 had an 85% lethal effect in both systems. The 50% lethal dose of the microapplicator and the micropipette was lower than that of the syringe but, of these, only the micropipette can combine the accuracy of the microapplicator and the speed of the syringe.

The effect of florfenicol egg-injection on embryonated chicken egg

Pathogens are an important and significant hazard for human and animal health. In recent years, antibiotics are used to treat different types of infection caused by bacterial agents. In veterinary medicine, antibiotics injected into hatching eggs to eliminate pathogens and prevention of egg transmission of disease, but the adverse effects of drugs have always been a major conc...

Monitoring virus harvesting time in embryonated chicken eggs inoculated with avian influenza H9N2 vaccine strain

Knowledge of virus and replication kinetic is one of the most important issues in the vaccine production. The present study aimed to evaluate the best harvesting time of H9N2 avian influenza virus (AIV) vaccine strain inoculated in specific pathogen free (SPF) embryonated chicken eggs (ECE)s. For this purpose, 10-5 dilution of AIV (A/Chicken/Iran/99/H9N2) was inoculated into 336, 11-day old ECE...

Detection of bluetongue virus by using bovine endothelial cells and embryonated chicken eggs.

Two systems, inoculation of bovine endothelial cells and of embryonated chicken eggs, were compared for detection of bluetongue virus (BTV) in blood specimens from experimentally inoculated sheep. For all BTV serotypes tested, embryonated chicken eggs detected longer periods of viremia than did bovine endothelial cells, primarily by detecting BTV in samples containing lower virus concentrations.

Optimization of incubation temperature in embryonated chicken eggs inoculated with H9N2 vaccinal subtype of avian influenza virus

There are little information about growth properties of low pathogenic (LP) avian influenza virus (AIV) in embryonated chicken eggs (ECEs) at different incubation temperatures. Knowledge of this information increases the quantity and quality of antigen in vaccine production process. For this purpose, 10-5 dilution of AIV (A/Chicken/Iran/99/H9N2) was inoculated (Intra-allantoic) into ...
