Objective To determine any association between streptococcal throat infection and plaque type psoriasis.
Patients and methods A cross-sectional study conducted on 30 psoriatics and 30 household controls at Bangabandhu Sheikh Mujib Medical University, Dhaka. Throat swabs of 60 patients were collected with all aseptic measures and sample were incubated in optimum condition for 3days. After this Streptococcus was identified by examining colonial morphology and sensitivity with bacitracin disc.
Results Streptococcal infection was found in 4 (13%) psoriasis patients and 1 (3%) in control group (p=1.964).
Conclusion In our study, we found no association between streptococcal throat infection and chronic plaque type psoriasis.
