Selection and preliminary characterization of temperature-sensitive mutants of type 5 adenovirus.
Eight temperature-sensitive (ts) mutants that replicate normally at 32 C but poorly, if at all, at 39.5 C have been isolated from mutagenized stocks of a wild-type strain of type 5 adenovirus. Three mutagens were employed: nitrous acid, hydroxylamine, and nitrosoguanidine. Ts mutants were isolated from mutagenized viral stocks with frequencies between 0.01 and 0.1%. All eight mutants had revers...
متن کاملIsolation and preliminary characterization of temperature-sensitive mutants of poliovirus type 1.
We isolated six temperature-sensitive mutants of poliovirus type 1 (Mahoney) by hydroxylamine mutagenesis and replica plating at 31, 33 (permissive), and 39 degrees C (restrictive). One of these mutants, designated tsB9, was chosen for more detailed examination. tsB9 accumulated 25% of the wild-type amount of virus-specific RNA at the restrictive temperature. We found that tsB9 was not able to ...
متن کاملIsolation and preliminary characterization of temperature-sensitive mutants of influenza virus.
Isolation of temperature-sensitive (ts) mutants was attempted from the WSN strain of influenza A virus which was grown and assayed in MDBK cells. After growth of wild-type virus in the presence of 5-fluorouracil, 15 ts mutants were selected for which the ratio of plaquing efficiency at 39.5 C to that at 33 C was 10(-3) or less. In pairwise crosses of ts mutants, recombination and complementatio...
متن کاملCoxsackievirus B3-associated panuveitis.
A 29-year-old woman suffered from headaches, diarrhoea, and high grade fever followed by a unilateral retinal vasculitis, papillitis, and chorioretinitis. Abnormal electrocardiographic findings and antibody titre dynamics strongly suggested a coxsackievirus B3 infection. With respect to prior observations on coxsackievirus B group associated uveitis this viral infection may be considered in pat...
متن کاملTemperature-sensitive cell-lethal mutants of drosophila: isolation and characterization.
One hundred and twenty-one sensitive (ts) sex-linked lethals were screened by means of X-ray-induced somatic crossing over to determine if any were ts cell-lethal mutants. Cell-lethal mutations were identified by their ability to block the development of homozygous clones when raised under restrictive conditions (29degrees). Twenty-two ts cell-lethal mutants were isolated and categorized into t...
