PEREZ C., Lilian et al. Impetigo in childhood, aetiology. Rev. chil. pediatr. [online]. 2001, vol.72, n.3, pp. 199-203. ISSN 0370-4106.  http://dx.doi.org/10.4067/S0370-41062001000300003.

Impetigo is a common childhood disorder and epidemiological changes about its causal agents have been reported during the last few decades. We attempted to determine the causal aetiological agents of impetigo in children in the north west of Santiago, Chile. A prospective study of 75 children with impetigo was carried out. They were classified as bullous or non-bullous and cultures were taken to determine the causal agent and its sensibility. 9% of cases presented with bullous impetigo, in all cases Staphylococcus aureus was isolated. 91% presented with non-bullous impetigo, the agents isolated were Staphylococcus aureus in 82%, S. aureus and Streptococcus pyogenes in 12%, S. aureus and Strep. group B in 3% and normal skin flora in 3%. S. aureus was sensitive to cloxacillin, a 1st generation cephalosporin and cotrimoxazole. We conclude that the most frequente causal agent in our area is Staphylococcus and that cloxacillin is the first line treatment of choice

Palabras llave : impetigo; aetiology; Staphylococcus aureus.
