Today it’s all about skin. These anatomical barriers include the skin, mucous membranes and bony encasements. But let’s not get too technical shall we?
In simple terms, the skin is the primary barrier for bacterial entry into our body. The epithelium is the first layer we encounter as it is the topmost and visible layer that covers our entire body followed by the dermis. The skin, comprising of both epidermis and dermis layer, is dry, acidic and has lower temperature all of which is not favourable for bacterial growth.
