摘要
The IncN plasmid N3 was transferred to bald strains of Salmonella typhimurium LT2 and Escherichia coli K-12. In both cases, transconjugants were found to carry short pili, which were designated N pili. They were very easily detached from cells and readily broken into short pieces. N pili were found to be straight inflexible rods 9.5 nm thick and sharply pointed at the distal end. The N-specific filamentous bacteriophage IKe and the lipid-containing phage PR4 both adsorbed to the pointed tips when mixed with cell-free suspensions of N pili. © 1979.
