Abstract

Introduction

Psoriasis is a chronic and inflammatory disease of the skin. recently, the role of microbial agents in the development or intensification of psoriasis has been considered, which is one of the most important factors of staphylococcus aureus bacteria. isolation of staphylococcus aureus and mrsa carriers is important in preventing transmission to other patients. therefore, this study was conducted to evaluate the colonization of methicillin-resistant staphylococcus aureus (mrsa) in psoriasis patients.

Methods

104 patients with psoriasis who referred to the shariati hospital in tehran in spring and summer of 1396 were referred to the dermatology and rheumatology clinic. then diagnostic tests were performed on staphylococcus aureus bacteria. in the next step, for detection of phenotypes of mrsa strains, methicillin susceptibility test was performed using disco diffusion method using cefocytosine disc. data were analyzed by t-test and chi-square and p value less than 0.05 was considered significant.

Results

104 patients with psoriasis were 32.25 years old and 69.32% were male and 30.76% were female. in the study of staphylococcus aureus colonization, 38.46% of the carriers had this bacterium. of these, 10.57% of the patients were methicillin-staphylococcal aureus. there was no meaningful relationship between sex, age and place of sampling among people carrying mrsa and others in t-test and chi-square tests.

Conclusion

Discussion and conclusion: considering the prevalence of mrsa strains in dermatologists, recognizing bacterial agents can play an important role in the treatment of psoriasis.
