Representative gel electrophoresis of several virulence genes from Pseudomonas strains isolated from sheep with pneumonia AÂ 16Â S rDNA gene (genetic marker Pseudomonas), with an expected band size of 618Â bp. BÂ ToxA gene with a band size of 396Â bp. This gene was represented in 59.2% of the isolated Pseudomonas strains
