Recent genetic studies have shown a large quantity of Pseudomonas spp. The use in extensive area or in patients with burns aren’t recommended, because of the risk of nephrotoxicity and absorption of the drug’s vehicle, polyethylene glycol, especially in patients with renal insufficiency. Mupirocin’s bactericidal impetito is increased by the acidic pH on the skin. Streptococci isolated from various skin lesions: Bullous impetigo in the genital area – intact and flaccid pustules, exulcerations and scaling in collarette.

Unique approaches for the topical treatment and prevention of cutaneous infections: It is listed in category B for use in pregnant and lactating women.

Several decades of epidemiological studies indicate that there are some strains of group A streptococci that elicit oropharyngeal infections, but rarely cause impetigo.

Staphylococcal infections are present in all age groups. Its actions against most Gram-positive bacteria are limited.

Erythromycin, being less expensive, can become the antibiotic of choice ampolliso the most impoverished populations.


Int J Antimicrob Agents. Bullous impetigo and scalded skin syndrome, caused by staphylococcal toxins and toxic shock syndrome, caused by staphylococcal impetibo streptococcal toxins are examples of toxin-mediated diseases.

Resistance, in vitro and in vivo, to fusidic acid has been verified but at low levels. How to cite this article.

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 3. Rather, glomerulonephritis may result from streptococcal cutaneous or upper respiratory tract infections, but the skin is the main previous site. Bacterial skin infections in children: The amoxicillin associated with clavulanic acid is the combination of one penicillin with a beta-lactamase inhibiting agent clavulanic acidthus enabling adequate coverage for streptococci and staphylococci.

It is a polypeptide formed by multiple components A, B and C. Del Giudice P, Hubiche P. Fusidic acid in dermatology. This antibiotic is not marketed in the United States.

Bacteria in biofilms are 50 to times more resistant to antibiotics than bacteria in plankton organisms that have little or no ability to move.

Dosage of antistreptolysin O may not be useful for cutaneous infections since its titles do not increase satisfactorily.

El impétigo (para Adolecentes)

Currently, the most frequently isolated pathogen is S. 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. The spectrum of the selected antibiotic must cover staphylococci and streptococci, both for bullous impetigo as well as for impeigo impetigo.

Fusidic acid is highly effective against S. There is strong evidence on the superiority, or at least the equivalence, of topical antibiotics compared to oral antibiotics in the treatment of localized impetigo.


The isolation of streptococci of groups other than A can mean a secondary infection of preexisting lesions or colonization on cutaneous surface. Bullous impetigo is almost universally caused by a single organism, S. These are germs with invasive potential, which can reach several tissular nips, such as the epidermis impetigodermis ecthyma or deeper subcutaneous tissue cellulite.

J Med Assoc Thai. On the other hand, there is a distinct group of strains that cause cutaneous infection but that do not affect the throat.

Clinical, bacteriological, toxicological and sensitivity to antibiotics studies. Its antibacterial action occurs through the inhibition of protein synthesis by binding selectively to bacterial ribosomes. Lancefield classification of streptococci is based on the cell wall’s C carbohydrate antigens, going from A to T.

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. Mupirocin in the treatment of impetigo. Impetigo in the French Guiana. Skin microflora and bacterial infections of the skin. Beta-hemolytic streptococcus group A is not commonly observed before two years of age, but there is a progressive increase in niios children.

The roof of the blister ruptures easily, revealing an erythematous, shiny and wet basis. Gram-negative bacilli are resistant to fusidic acid. Community-associated methicillin-resistant Staphylococcus aureus and impetigo. Mupirocin and fusidic acid are the first choice options. Topical antibiotics are the treatment of choice for most cases of impetigo.
