Recombinant viruses as vaccines against viral diseases.
Vaccine approaches to infectious diseases are widely applied and appreciated. Amongst them, vectors based on recombinant viruses have shown great promise and play an important role in the development of new vaccines. Many viruses have been investigated for their ability to express proteins from foreign pathogens and induce specific immunological responses against these antigens in vivo. General...
متن کاملVaccines and viral antigenic diversity.
Antigenic diversity among ribonucleic acid (RNA) viruses occurs as a result of rapid mutation during replication and recombination/reassortment between genetic material of related strains during co-infections. Variants which have a selective advantage in terms of ability to spread or to avoid host immunity become established within populations. Examples of antigenically diverse viruses include ...
متن کاملAntibiotic Sensitivity of Ornithobacterium rhinotracheale Isolates Associated with Respiratory Diseases.
187 commercial checken flocks affected with respiratory diseases were examined for Ornithobacterium rhinotracheale isolation. The bacterium was isolated from 105 (56.2%) poultry flocks. Drug sensitivity test using standard disk diffusion technique was performed with 19 antibiotics. All the isolates were susceptible to tiamulin and most of them were susceptible to chloramphenicol and linco-spect...
متن کاملActivity of Nitazoxanide Against Viral Gastroenteritis: A Systematic Review
Introduction: Nitazoxanide is an oral anti-parasitic agent that has been found to have broad antiviral activity. Its role in the treatment of viral gastroenteritis is not well-studied. Given the worldwide prevalence of viral gastroenteritis, particularly in developing nations, a systematic review of this topic would be valuable. Methods: A formal literatu...
