There is a predominance of lesions in exposed areas, especially in the limbs and face Figures 5 and 6. Mupirocin in the treatment of impetigo. Aminoglycosides exert their antibacterial activity by binding to the 30S ribosomal subunit and interfering with protein synthesis. Bullous impetigo and scalded skin syndrome, caused by impehigo toxins and toxic shock syndrome, caused by staphylococcal or streptococcal toxins are examples of toxin-mediated diseases. The act of handwashing, with antiseptic soap or even regular soap, especially amongst children caretakers, severely decreased their chance of acquiring infections such as pneumonia, diarrhea and impetigo.

Bacterial skin colonization and infections in patients with atopic dermatitis. New horizons for cutaneous microbiology: Luciana Baptista Pereira Vulga.

Crusted impetigo can occur in normal skin or impetiginisation may appear over a previous dermatosis such as atopic dermatitis, contact dermatitis, insect bites, pediculosis and scabies. In addition, oral antibiotics have more side effects than topical antibiotics. 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.

Removal of amino-terminal extracellular domains of desmoglein 1 by staphylococcal exfoliative toxin is tratamisnto to initiate epidermal blister formation. Estas bacterias habitan en la piel y en la nariz. The commercially available formulation is a mixture of neomycin B and C, while framycetin, used in Canada vklgar several European countries, is composed of pure neomycin B.


Mupirocin acts by inhibiting bacterial protein synthesis, by binding with isoleucyl-tRNA synthetase enzyme, thus preventing the incorporation of isoleucine into protein chains.

Community-associated methicillin-resistant Staphylococcus aureus and impetigo. Bullous impetigo in diaper area. Impetigo in a population over 8. Bacitracin A is the main component of commercial products and is generally formulated as a zinc salt.

Unique approaches for the topical treatment and prevention of cutaneous infections: The remainder of the roof can be seen as a collarette at the periphery and the confluence of lesions promotes the appearance of polycyclic figures Figures 2 and tratakiento.

Sometimes, the overgrowth of these bacteria causes skin diseases, and in other occasions, bacteria that tratmaiento normally found on the skin can colonize it and cause diseases. Bacterial resistance rate is low, around 0. Community-acquired methicillin-resistant Staphylococcus aureus: Staphylococcal strains that are resistant to erythromycin will also be resistant to clarithromycin, roxithromycin and azithromycin.

In meta-analyses publications, no difference between these two agents was demonstrated. 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. Other phage types involved are 3A, 3C and Impetigo, a reassessment of etiology and therapy.

Rather, glomerulonephritis may result from streptococcal cutaneous or upper respiratory tract infections, but the skin is the main previous site. The main etiological agent has varied over time.


It is the result of Streptomyces fradiae fermentation. Sensitized patients may cross-react when exposed to other topical or systemic aminoglycosides.

Las lesiones suelen desaparecer en el transcurso de una semana. Recent genetic studies have shown a large quantity of Pseudomonas spp. Lancefield classification of streptococci is based on the cell wall’s C carbohydrate antigens, going from A to T.

Las lesiones, que pueden presentarse en cara, labios y orificios nasales, cuero cabelludo, brazos o piernas e, incluso, axilas, se diseminan cuando el afectado se rasca. It occurs in adults and children but rarely in those under two years of age.

Bacteria in biofilms are 50 to times more resistant to antibiotics than bacteria in plankton organisms that have little or no ability to move. Toxins are the greatest virulence factor of S. A review of its use in the management of impetigo and other uncomplicated superficial skin infections.

Besides inducing antibiotic tolerance, biofilms can increase bacterial virulence. Treatment of impetigo does not reduce the risk of glomerulonephritis, but it reduces the dissemination of nephritogenic strains in the population. A systematic review and meta-analysis of treatments for impetigo. Its actions against most Gram-positive bacteria are limited. It is less effective in traumatic lesions ijpetigo those with abscess formation usually caused by anaerobic bacteria and MRSA.
