Role of Staphylococcus aureus Biofilm in Teeth Plague and Mouth Infection in Al-Rifai District

Abstract

Staphylococcus aureus is one of the furthermost common microbes that can cause opportunistic infections, capable of inflicting potential life-threatening infections such as pneumonia, urinary tract infection, bloodstream infection, and infectious endocarditis. Biofilms are considered the common bacterial mode in the environment and are also, considered the Main cause of clinical and dental infections in our population. A total of 150 swabs from patients who have oral infections and plague from local hospitals and private clinics, then the specimens treated with microbiological and biochemical procedures are done to identify S. aureus. Three methods are used for biofilms to be detected, CRA (Congo Red Agar method), TM (Tube method), and MtP(Microtiter plate method ) the results of CRA can be shown by the appearance of colonies in 82% of the colonies' biofilm producers (slime) and 17.5% non-biofilm producer. In the TM and MtP methods, the results can shower by weak, moderate, and strong adhesive biofilm bacteria. antibiotics susceptibility was accomplished by disc distribution technique on sensitivity (Mulare Hinton) agar and observed High resistance to many antibiotics resulted in biofilm-forming and High sensitivity to other antibiotics.
