Perspective on Possible Recombination Event in Fusion Protein Gene of Newcastle Disease Viruses Isolated in Iran
Background and Aims: Newcastle disease (ND), caused by the virulent Newcastle disease virus (NDV), is one of the most important viral diseases in birds. In recent years recombination occurring throughout the NDVs genome isolated in China and Indonesia has been reported. This study was focused to investigate the recombination events in the F gene of the Iranian NDVs to generate useful data that ...
متن کاملGenetic Studies of Influenza Viruses
The passage of newly isolated, filamentous Asian (A2) influenza viruses in the presence of non-infective PR8 (A) virus results in the rapid emergence of virus of Asian (A2) antigenicity but PRS-like growth capacity and spherical morphology. Evidence is presented that this effect results from genetic interaction of the infective Asian and non-infective PR8 viruses rather than from spontaneous ch...
متن کاملStudies of the Origin of Bacterial Viruses
Exposure of B. megatherium 899 to about 5 x 10(-3)M MnCl(2) for 10 minutes at 25 degrees C. results in an increase of about ten times in the proportion of phage-producing cells, terramycin-resistant cells, streptomycin-resistant cells, and phage-resistant cells. The proportion of phage-producing cells reaches a maximum in about 4 hours and that of the other cells is reached in about 8 hours.
متن کاملElectron Microscope Studies of Bacterial Viruses.
Physico-chemical (Schlesinger, 1933; Northrop, 1938; Kalmanson and Bronfenbrenner, 1939) and biological (Ellis and Delbriick, 1939) studies of bacterial viruses (bacteriophages) in the last few years have led to a revival of interest in this group of viruses, particularly as a material on which one can study under very favorable conditions properties which may be common to all viruses. Ease and...
متن کاملJoshua Lederberg on Bacterial Recombination.
This paper describes the first genetic analysis of bacteria. Before its publication,most scientistswondered if bacteria even had genes. Many thought bacteria to be a distinct form of life, separate from higher organisms like Drosophila and maize, which were known to follow Mendel’s principles of heredity. But when George Beadle and Edward Tatum showed in 1941 that Neurospora obeys Mendel’s laws...
