Mutation Preventing Capsular Polysaccharide Synthesis in Escherichia coli K-12 and Its Effect on Bacteriophage Resistance
AUTOR(ES)
Radke, Kathryn L.
RESUMO
A mutant strain of Escherichia coli K-12 was found in which spontaneous mutation to phage T7 resistance occurred at a very low frequency. T7 resistance in the parental strain from which this mutant was derived resulted from a mutation to excess capsular polysaccharide synthesis. The mutation preventing T7 resistance, non-9, inhibited capsule formation when transduced into capsulated strains. The non-9 mutation was cotransducible with his, the gene order in this region being non-9 his Su-1.
