FIG. 1.
Bacterial diversity associated with H. obsoletus. (A) Example of LH-PCR profiles of whole insects collected in 2005 to 2007 from uncultivated areas in Piedmont, Italy. Numbers refer to different individuals tested. (B and C) DGGE profiles, in 7% polyacrylamide gels with 20 to 40% (B) and 30 to 50% (C) denaturation gradients, of partial 16S rRNA bacterial genes amplified from DNA extracted from whole insects collected in 2005 to 2007 from wastelands in Piedmont, Italy. Numbers above the lanes refer to the numbers of tested individuals. The identities of sequences of bands marked with arrows are given in Table 1 according to the band identification (bands A1 to A5 and B1 to B3).
