Background: E. coli infection is considered as an
important bacterial problem associated with significant economic losses and
usually associated with a variety of disease conditions, including acute
septicaemia, haemorrhagic enteritis, pericariditis, salpingitis and complicated
air saculitis.  These considerations
suggest that control of E. coli by
vaccination could be of great value especially live vaccine that based on
defined mutations that impair and non-revering virulence.



Material and Methods: Wild type O78 strain, Live O78 aroA gene deleted vaccine and Live O78 crp gene deleted vaccine were used to accomplish this study.
Phenotypic characterization was adopted by studying the cultural, biochemical
and serological properties. Also genotypic characterization was studied for 16S rRNA, aroA and crp genes.



Results: Growth
pattern on different media differed among the used strains as the wild type and
Δ aroA mutant were nearly similar while the Δ crp mutant strain was greatly differed.  Biochemically the difference between the
wild-type and Δ aroA mutant was inability of mutant strain to produce arginine
dihydrase (ADH) and fermentation of saccharose. On the other hand the Δ crp mutant failed to produce ADH and to
ferment any of the carbohydrates except glucose. A successful amplification of
the 16S rRNA gene at 585 bp was
detected with the all tested strains while was 1206 bp with only wild type and
Δ crp mutant strain when aroA gene primers were used. Regarding crp genes, the amplified products was at
1029 bp with the wild and Δ aroA mutant but not with Δ crp mutant strains.



Conclusion: Findings
of this study prove the use of methods based on molecular techniques like PCR
to differentiate between different types of E. coli either wild or vaccinal
mutant type strains. Also it may help in exclusion or proving the return back
to virulence of the mutant vaccinal strains.
