The first observation of plasmid retrotransfer by plasmids isolated from environmental sources is reported. A high incidence of retrotransferring ability amongst plasmids isolated from epilithic bacteria was found; some of these plasmids retrotransferred an IncQ plasmid at very high frequencies. Despite the broad host‐range of the majority of the plasmids, only five out of 12 could be assigned to an incompatibility group by DNA hybridization. All five were designated IncP1; this revealed a limitation of probes derived from clinical sources for use with environmental isolates. Incompatibility testing by plate mating suggested that four additional plasmids displayed varying, albeit lower, degrees of incompatibility to the IncP1 plasmid RP1.
