Abstract: | We analysed 38 French isolates of Legionella anisa by means of pulsed-field gel electrophoresis (PFGE) with single or double digestion. Double digestion was more discriminatory than single digestion, and can thus be useful for epidemiological studies of L. anisa. Several isolates from different parts of France clustered together on the basis of their PFGE patterns (similarity cutoff of 80%), suggesting that the L. anisa population structure is homogenous or that a few clones of L. anisa strains have spread widely in France. |
