Impetigo bolhoso é uma infecção superficial contagiosa da pele causada por algumas cepas de Staphylococcus aureus que liberam localmente toxinas que são capazes de clivar a desmogleína I, uma proteína envolvida na adesão intercelular de queratinócitos epidérmicos. Em contraste com as bolhas muito superficiais, de rápida eliminação e raramente observadas do impetigo não bolhoso, as bolhas do impetigo bolhoso são tensas e bem demarcadas, às vezes atingindo vários centímetros de diâmetro antes da ruptura. | |||
