Abstract :
[en] An intracellular symbiotic bacterium was isolated from the flora of a natural clone of the black bean aphid Aphis fabae. The strain was able to grow freely in aerobic condition on a rich medium containing 1% of each of following substrates; dextrose, yeast extract and peptone of casein. Pure culture was achieved through the use of solid-phase culture on the same medium and was designated CWBI-2.3T. 16S ribosomal DNA sequence analysis revealed that CWBI-2.3T strain was a member of the gamma-3 subgroup of the class Proteobacteria, having high sequence identity (>99%) with the R-Type of secondary endosymbiont found in several aphid species Serratia symbiotica. As strain CWBI-2.3T (=LMG 25624T =DSM 23270T) was the first R-type symbiont to be isolated and characterized, we proposed to designate it as the type strain of Serratia symbiotica species.
