Avian Virus Growths and their Etiologic Agents

摘要: Publisher Summary This chapter focuses on avian virus growth and their etiologic agents. Despite great apparent differences in pathogenesis etiology of the growths, numerous findings have consistently suggested a distinct continuity inter associations, both natural occurrence viral transmission various neoplastic states. A notable trend recent investigation these tumors has been shift principle away from earlier purely qualitative biologic experimentation toward application methods designed to afford quantitation definitive correlation data diverse sorts. The most work with tumor viruses concerned further characterization individual strains agents penetration into still obscure province cell–virus interactions at ultrastructural biochemical levels. Although evidence well established, concepts interrelationships diseases represented, this day, practically every conceivable variation potentialities. factors that influence regulate quantitative aspects host response do not differ those other diseases. Among helpful advances study is recent, very considerable increase knowledge nature themselves. Systematic utilization tissue culture systems for undertaken only years. It intent attempt some many obtained, primarily more years, filterable
