“…This plasmid, originally isolated from Pseudomonas aeruginosa, is capable of mobilizing the Acinetobacter chromosome and transferring chromosomal genes between different mutant auxotrophic derivatives of strain EBF 65/65. Another plasmid, pAV1 (distinct from pAV1 described in Table 8), transferred genes at frequencies up to 10%, i.e., at a rate about 1000-fold higher than RP4 (Vivian, 1991). A variety of plasmids can be transferred by conjugation to Acinetobacter from enteric bacteria, although not all are stably maintained (Towner, 1991a).…”
