Molecular detection of biofilm coding genes in Staphylococcus aureus

In accordance with epidemic COVID-19, the elevated infection rates, disinfectant overuse and antibiotic misuse what led to immune suppression in most of population addition genotypic phenotypic alterations microorganisms, so a great need reevaluate genetic determinants that responsible for bacterial community (biofilm) has been raised. A total 250 clinical specimens were obtained from patients Baghdad hospitals streaked on Mannitol salt agar medium. The results revealed 156 isolates appeared as round yellow colonies, indicating they mostly identified Staphylococcus aureus specimens. resistance pattern methicillin 37.17% (n=58), Amoxicillin-Clavulanate 58.9% (n=92), chloramphenicol 6.4% (n=10), Tetracyclin 62.8% (n=98), ceftriaxone 53.8% (n=84), Ciprofloxacin Gentamicin 42.3% (n=66), levofloxacin 28.2% (n=44), Penicillin 33.3% (n=52). demonstrated 49 multidurg resistance. biofilm formation ability MDR was detected 120 S. (76.92 %) found be adherent varied degrees. Only fifty (32.05% total) classified strong producers. Twenty-three (14.75%) moderate producers, forty seven (30.12%) weak
