|
| Summary |
| |
In this study we used one reference Climson University (CU) stain and 3 virulent field strains isolated from naturally infected chicken and identified
|
|
|
| |
| |
as P.Multocida.DNA was extracted from all strains and subjected to restriction endonuclease analysis, using EcoRI, HpaIIand Hind III revealing that,great similarity between either the reference or local virulent field isolates.
|
|
|
| |
| |
The obtained results indicated that the most differentiable restriction endonuclease enzyme was the Hind III, which showed differtent band patterns between different strains.
