**4.7 Analysis of cloned nucleotide sequences of the PCR products amplified in PCRs for P- and F17-fimbrial genes**

Sequence analysis of the cloned fragments, originated from PCR products obtained in PCRs for P- and F17-fimbrial genes, was performed with the computer program BLAST on the Internet page of the National Center for Biotechnology Information, US National Library of Medicine (http://www.ncbi.nlm.nih.gov) searching for homology in the GenBank nr database.
