Enterobacterial tetracycline resistance in relation to plasmid incompatibility.

Author information

Molecular Genetics Unit, Central Public Health Laboratory, London, UK.


Sixty-eight well-characterized antibiotic resistance (R) plasmids belonging to 19 Incompatibility groups were screened with probes representing heterologous classes (A-E) of the enterobacterial tetracycline resistance (TcR) determinant. The Class B determinant was shown to be predominant in the IncF and IncH complexes and the IncC group. The Class A determinant was shown to be predominant in the IncP and IncM groups. There was no correlation between distribution of the class of TcR gene and the genus or the species of the host bacterial strain. The plasmids R714a (IncFI) and pHH1465 (IncC) contained TcR determinants which had no homology with any of these five probes.
