چکیده

A strategy based on a vector host-dependent for autonomous replication, pSA3182, was utilized both for the rapid screening for Staphylococcus aureus genes essential for cell viability and for the introduction of specific polarity-neutral deletions in nonessential genes. The results obtained support the use of pSA3182 for both purposes.

Comparison of Relation between Resistance Pattern to Erythromycin and Tetracycline and the Prevalence of Superantigens Coding Enterotoxins A and B in Staphylococcus aureus Isolated from Broiler Poultry in Ilam, Iran

Staphylococcus aureus is a gram-positive coccus that, in specific conditions, is able to generate various diseases. By secreting different enterotoxins, this bacterium prepares the settings to attack the host; among these, enterotoxins A and B play the most important roles in food poisoning. This study was performed to trace the genes coding enterotoxins A and B in Staphylococcus a...
