Abstract
THE conjugal transfer of episomal elements in bacteria is assumed to take place through specific pili, which are formed on the surface of donor bacteria carrying these elements1. Recipient ability seems to be influenced by the surface structure of the cell wall2. We previously isolated rough mutants of Salmonella typhimurium LT-2 which had increased recipient abilities for the conjugal transfer of foreign deoxyribonucleic acids. B. A. D. Stocker (Stanford University) has shown that there are several types of these mutants by using rough-specific phages (personal communication).
