Web(host temperature), IncHI plasmid conjugation is thermo-sensitive, with an optimal conjugation rate between 22°C and 28°C. At 37°C, under laboratory conditions, the con-jugation is barely detectable (Taylor and Levine, 1980). This unusual behavior suggests that IncHI plasmids might be involved in the dissemination of antibiotic resistance WebJul 7, 2008 · IncHI plasmids are the only known plasmids in human pathogens that are temperature sensitive for transfer. Using R27 sequence data and transposon mutagenesis, the transfer determinants responsible for the spread of H-plasmids were identified ( Rooker et al., 1999; Sherburne et al ., 2000 ).
