Primers, pA (50-AGA-GTT-TGA-TCC-TGC-CTC-AG-30; 100 pmol
ml1) and pE (50-CCG-TCA-ATT-CCT-TTG-AGT-TT-30; 100 pmol ml1)
based on conserved regions of the 16S rRNA gene were used to
direct the amplification. The procedure consisted of: denaturation
at 95 C for 5 min, then 35 cycles of 94 C for 1 min, 55 C for 1 min
and 72 C for 1 min followed by a final extension at 72 C for 5 min
(Ouoba et al., 2008). Positive PCR products were confirmed by
