Retapamulin is a semi-synthetic agent derived from an edible mushroom called Clitopilusscyphoides. Take a look at this link.

Removal of amino-terminal extracellular domains of desmoglein 1 by staphylococcal exfoliative toxin is sufficient to initiate epidermal blister formation. Streptococci isolated from various skin lesions: Blisters are localized in bullous impetigo and disseminated in scalded skin syndrome. Thus, their path goes from normal skin to injured skin and may subsequently reach the oropharynx.

Erythromycin, being less expensive, can become the vulgarr of choice for the most impoverished populations.

Host factors, such as integrity of the skin barrier with its acidic pH, presence of sebaceous secretion fatty acids, particularly oleic acidlysozyme and production of defensins vlugar adequate nutritional status, play an important role in resistance to infection. Estas bacterias habitan en la piel y en la nariz.
