I t was concluded tha t the influenza viruses m a y exert toxic effects on an organ which usual ly does ...
متن کاملFilamentous influenza viruses.
Clinical isolates of influenza virus produce pleomorphic virus particles, including extremely long filamentous virions. In contrast, strains of influenza that have adapted to laboratory growth typically produce only spherical virions. As a result, the filamentous phenotype has been overlooked in most influenza virus research. Recent advances in imaging and improved animal models have highlighte...
متن کاملAvian influenza viruses
Influenza viruses belong to the Orthomyxoviridae family, genus Orthomyxovirus, and are divided into three types – A, B, and C – based on the antigenic differences between their nucleoprotein and matrix proteins. Influenza A viruses are further subdivided into several subtypes. A most striking feature of influenza viruses is their ability to continually change their genetic structure – in partic...
متن کاملReproduction of Influenza Viruses
Influenza A and B virus reproduction in the allantoic membrane of the intact chicken embryo was studied quantitatively with particle enumeration procedures. Virus particles were enumerated on the basis of two independent properties; capacity to infect and to cause hemagglutination. The infective property of influenza B virus (Lee) was even more unstable than that of influenza A virus (PR8). Ina...
