Analysis of the bacterial communities within the oesophageal bulbs of B. oleae after the cohabitation experiments: The DGGE profiles of 16S rRNA gene fragments obtained by amplification with the 63FGC/518R primer set. The letter M on the gel image indicates the marker used for the normalization of the bands in the profiles. L refers to a lab sample, while B and A correspond to the two different Ca. E. dacicola lineages from wild flies (htB and htA, respectively). The other headings refer to the two different cohabitation treatments
