Removal of amino-terminal extracellular domains of desmoglein 1 by staphylococcal exfoliative toxin is sufficient to initiate epidermal blister formation.

Tratamientoo impetigo is usually caused by S. It is particularly important in the neonatal period, starting usually after the second week of life, although it can be present at birth tratamiemto case of premature membranes rupture.


It works by interfering with bacterial cell wall formation.

tratzmiento A review of its use in the management of impetigo and other uncomplicated superficial skin infections. Thus, benzathine penicillin or those sensitive to penicillinases are not indicated in the treatment of impetigo. Besides inducing antibiotic tolerance, biofilms can increase bacterial virulence.

Its actions vuglar most Gram-positive bacteria are limited. Skin microflora and bacterial infections of the skin. Streptococcus pneumoniae and Streptococcus pyogenes are highly resistant to neomycin, which is why the drug is usually associated with tgatamiento to treat cutaneous infections.
