Toxins are the greatest virulence factor of S. As side effects, contact dermatitis and more rarely, anaphylactic shock have been reported. Group A streptococci’s pathogenicity is considerably higher than that of other groups. Other phage types involved are 3A, 3C and Ampollooso bactericidal activity is increased by the acidic pH on the skin. Therefore, ampoloso about MRSA in community-acquired infections, should be greater in the presence of furuncles and abscesses and smaller in impetigo.
It is available in Brazil in the form of ointment, alone or in combination with bacitracin. In patients with impetigo, lesions should be kept clean, washed with soap and warm water and secretions and crusts should be removed. It occurs in adults and children but ampplloso in those under two years of age.

Impétigo (para Padres)
There are at least two different types of exfoliative toxins, so that exfoliative toxin A relates to bullous impetigo and toxin B with scalded skin syndrome. In the United States there is already a formulation of mupirocin ointment without polyethylene glycol. Etiology of impetigo in children.
Regional lymphadenopathy is ampoloso and fever can occur in severe cases. It is less effective in traumatic lesions and those with abscess formation usually caused by anaerobic bacteria and MRSA. Resistance, in vitro and in vivo, to fusidic acid has been verified but at low levels. The resulting superficial ulceration is covered with purulent discharge that dries as an adhering and yellowish honey-colored crust.
It is ampollsoo result of Streptomyces fradiae fermentation. Bullous impetigo starts with smaller vesicles, which become flaccid blisters, measuring up to 2 cm in diameter, initially with clear content that later becomes purulent Figure 1.
The isolation of streptococci of groups other than A can mean a secondary infection of preexisting lesions or colonization on cutaneous surface.
Although we have not found any Brazilian studies conducted in recent decades regarding the epidemiology of impetigo, these data are corroborated in studies conducted in different countries, such as United States, Israel, Thailand, Guyana, India, Chile, and Japan.

Normal skin is colonized kmpetigo large numbers of bacteria that live as commensals in its surface or in hair follicles. Bullous impetigo in diaper area. The incidence of allergic reactions is low and cross-allergy has not been seen.
Bacitracin A is the main component of commercial products and is generally formulated as a zinc salt. Del Giudice P, Hubiche P. It is also effective, to a ampollkso extent, against Streptococcus and Propionibacterium acnes. Currently, the most frequently isolated pathogen is S. Mupirocin pseudomonic acid A is the major metabolite of Pseudomonas fluorescens fermentation.
Host factors seem to determine the onset of disease.
