Molecular Characterization and Resistance Patterns of Multidrug MethicillinResistant Staphylococcus aureus Isolated from Wound
Staphylococcus aureus is a serious risk to public health as it triggers human infections ranges from wound abscess to life threatening states. As involvement to the global effort the objectives of this study were to examine the incidence of Methicillin-resistant Staphylococcus aureus (MRSA) in Taif region, Saudi Arabia. Moreover, this work aimed to estimate the relation between the phenotypic antibiotic susceptibility patterns and the antibiotic resistance genes mong MRSA isolates. A total of 67 wound specimens were taken from patients. Methicillin-resistant Staphylococcus aureus (MRSA) was selected by growing on Mannitol Salt Agar supplemented with methicillin (5 mg/l). The prevalence of methicillin-sensitive S. aureus (MSSA) and methicillin-resistant (MRSA) wound carriage among patients was 51 and 49 %, respectively.
Biofilm is the layer which is formed with the matrix produced through accumulation of the free organisms on a proper surface. This layer makes treatment of S.aureus infections difficult as it makes S.aureus resistant to antibiotics and inhibits phagocytosis.
The pathogenity of S. aureus strains are related with features like its adherence, various toxins, enzymes, structural and extracellular factors. In our study, the relationship between biofilm formation and lipase, protease, urease activity were investigated in S. aureus strains isolated from various clinical specimens sent to our microbiology laboratory.
