“…The presence or absence of pAV2 in strains of EBF65/65 has no bearing on the incompatibility determinations for pAVl since all the strains were pAV2f (Hinchliffe & Vivian, 1980a). Similar results were also obtained by Hinchliffe & Vivian (1980b) in strains which differed with respect to pAV2. Incompatibility remained the same when similar crosses were performed in strains that were all pAV2-(E. Hinchliffe & A. Vivian, unpublished results).…”

“…It reamins for us to attempt mobilization of amikacin resistance. Recently, a naturally occurring transmissible plasmid, pAV1, in A. calcoaceticus has been shown to mobilize nontransmissible neomycin resistance (13). Third, a chromosomal locus could be repressed in susceptible strains only to be derepressed under selective environmental conditions.…”

We studied 21 strains of amikacin-resistant Serratia marcescens from three different U.S. cities, Twenty of the 21 strains contained conjugative R plasmids mediating gentamicin and tobramycin resistance. Amikacin-resistant S. marcescens from two cities predominated in protracted outbreaks. Conversely, the amikacin-resistant Charleston strain (serotype 02/03:nonmotile) was isolated from only four patients during an outbreak of gentamicin- and tobramycin resistant, amikacin-susceptible S. marcescens (serotype O19:O17). Five different representative amikacin-resistant S. marcescens, each containing a single conjugative plasmid, elaborated a nontransferable aminoglycoside (6')-N-acetyltransferase [AAC(6')] with similar substrate profiles in addition to other transferable aminoglycoside-modifying enzymes. One amikacin-resistant S. marcescens cured of its plasmid and another naturally occurring plasmid-free amikacin-resistant S. marcescens elaborated only AAC(6')-1. These data support the concept of a chromosomal locus in S. marcescens for AAC(6')-1 which commonly coexists with plasmid-mediated genes for aminoglycoside-modifying enzymes.

“…Gene mapping and chromosome organisation in Acinetobacter has been reviewed by Vivian (this volume), but in summary,two RP4-carrying donor strains which donated the EBF65/65 chromosome in opposite directions from different origins were isolated and, as a result, it was possible to demonstrate that the linkage map of EBF65/65 is circular (Towner and Vivian, 1976b; Towner, 1(78). Subsequently a number of other plasmids have also been shown to mobilise chromosomal genes of Acinetobacter (Towner and Vivian, 1977;Hinchliffe and Vivian, 1980b), but to date this property seems to be restricted to members of the PI incompatibility group.…”

“…This strain carried a 128 kb conjugative plasmid which specified resistance to sulphonamides, designated pA V1, and a 23 kb non·conjugative plasmid which specified resistance to kanamycin/neomycin and tetracycline, designated pA V5 (Hinchliffe et ai., 1980;Divers et ai., 1985). pA V1 is an unusual example of a P1 incompatibility group plasmid with a restricted host range ; however, although it is unable to transfer to E. coli K12, it is freely transmissible between several different strains of Acinetobacter and also serves to mobilise both pAV5 and the Acinetobacter chromosome (Hinchliffe and Vivian, 1980b;Divers et aI., 1984).…”

“…This plasmid transferred at frequencies up to 10% (about 1000-fold higher than RP4) between strains of EBF65/65. Transfer of chromosomal genes was also up to 100 times more efficient, although it was not possible to discern any clear orientation of transfer (Hinchliffe and Vivian, 1980b). Nevertheless, the co-inheritance of markers transferred by pAVl has been successfully used to map a number of catabolic genes on the chromosome of EBF65/65 (Vakeria et a1., 1984; Fig.…”

That occasion was so well attended and productive that there were soon discussions about how, when and where the next meeting should be held. This time, however, there was sufficient confidence to think of a more substantial meeting and to plan for the proceedings to be published. It emerged that there was wide agreement that the time was ripe to take stock of the entire biology of Acinetobacter: its occurrence and taxonomy; its molecular biology, biochemistry and physiology; its clinical importance and its industrial and commercial applications. The 2nd International Workshop on Acinetobacter took place from 6th to 7th September, 1990, at the Institut Pasteur, Paris, and was sponsored by the Federation of European Microbiological Societies. There were about 100 participants from 19 countries. The backbone of the meeting consisted of 23 plenary lectures. There were 28 posters and the meeting closed with a general discussion which went on long after the official finishing time despite all the counter-attractions of a sunny Parisian Friday afternoon. Indeed discussions continued while cruising along the Seine and while dining at the top of the Tour Montparnasse. However, the vitality and usefulness of even the most successful meeting is difficult to transmit by the printed word. The editors decided, therefore, not simply to publish the proceedings of the Workshop, but rather to commission a set of review articles with the aim of giving an up-to-date and rounded picture of our current knowledge of the genus Acinetobacter. These reviews, together with a
