Investigation about Pseudomonas aeruginosa Isolates on citrus and test their susceptibity to some Antibiotics


As wellknown that P. aeruginosa are opportinastic pathogen bacteria. 100 samples were collected from citrus (Leaves, Stalks and Fruits) and studied for the existence of P. aeruginosa . Results indicated That (27%) of samples were positive for P. aeruginosa. There is no difference in susceptibility of P. aeruginosa of different sources towards antibiotic (Cefotaxime, Gentamycin, Amoxicillin, Cephalexine and Colistin). Also results showed three groups of resistance. The first group was 100% while the resistance of Amoxicillin, Colistin and Cephalexine was 60 % for the second and the third groups which were sensitive for Gentomycin and Cefotaxime.
