Method |
To document gene transfer frequencies,
researchers subjected wild-type strains or natural communities
from a range of environments to treatment
with donor strain GTAs (Gene Transfer Agent) and documented the rates of
GTA-mediated gene transfer of kanamycin resistance. The gene transfer frequencies
were calculated by dividing the number of antibiotic resistant cells by the total number of
recipient cells in the culture (S6), both measured as colony-forming units (cfu)/ml. |
Comments |
Environmental gene
transfer frequencies ranging from 6.7×10^-3 to
4.7×10^-1 (Table 1) are 1900 to 459 million times
the frequency for transformation (Williams et al., 1997 PMID 9284562) and 650,000
to 31 million times the frequency of transduction
previously measured in the marine environment
(Jiang et al., 1998 PMID 9687430). |
