It is not active against bacteria of the normal cutaneous flora and therefore does not alter the skin’s natural defense.

It is highly effective against Staphylococcus aureus, Streptococcus pyogenes and all other species of streptococci except those of group D. The first-generation cephalosporins, such as cephalexin and cefadroxil, may be used, since no differences between them was found in a metaanalysis.

Staphylococci that possess PVL gene cause suppurative cutaneous infections such as abscesses and furuncles. Currently, the most frequently isolated pathogen is S. Staphylococcal strains that are resistant to erythromycin will also be resistant to clarithromycin, roxithromycin and azithromycin.

Bullous impetigo in diaper area. The incidence of allergic reactions is low and cross-allergy has not been seen. Neomycin sulfate is active mainly against aerobic Gram-negative bacteria Escherichia coli, Enterobacter aerogenes, Klebsiella pneumoniae, Proteus vulgaris.

Diagnosis and treatment of impetigo. Clinical cure of impetigo with retapamulin is well defined, when compared with placebo. A review of its use in the management of impetigo and other uncomplicated superficial skin infections. Mupirocin and fusidic acid are the first choice options. Regulatory mechanism ampolloao exfoliative toxin production in Staphylococcus impefigo. It is less effective against Gram-negative bacteria, but exhibits in vitro activity against Haemophilus influenzae, Neisseria gonorrhoeae, Pasteurella multocida, Bordetella pertussisand Moraxella catarrhalis.

Rheumatic fever can be a complication of streptococcal pharyngitis or tonsillitis, but it does not occur after skin infections. It is also effective, to a lesser extent, against Streptococcus and Propionibacterium acnes. Besides inducing antibiotic tolerance, impetito can increase bacterial virulence.

Beta-hemolytic streptococcus group A is not commonly observed before two years of age, but there is a progressive increase in older children. Coagulase negative staphylococci ampollosl the most common organisms on the normal skin flora, with about 18 different species, and Staphylococcus epidermidis being the most common of the resident staphylococci.

The path would be from the nares or perineum to normal skin, and later to injured skin. Fusidic acid is highly effective against S. The isolation of streptococci of groups other than A can mean a secondary infection of preexisting lesions or colonization on cutaneous surface. Staphylococcal impetigo is usually caused by S. Its antibacterial action occurs through the inhibition of protein synthesis by binding selectively to bacterial ribosomes.

Aminoglycosides exert their antibacterial activity by binding to the 30S ribosomal subunit and rn with protein synthesis. Community-acquired methicillin-resistant Staphylococcus aureus: Bacterial skin infections in children: Each lesion measures 1 to 2 cm in diameter and grows centrifugally Figure 4.

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.

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. Impetigo is a common cutaneous infection that is especially prevalent in children.

Luciana Baptista Pereira Av. In patients with impetigo, lesions should be kept clean, washed with soap and warm water and secretions and crusts should be removed. Br J Gen Pract. One should take into account the possibility of resistance to S. The resulting superficial ulceration is covered with purulent discharge that dries as an adhering and yellowish honey-colored crust.

Schachner L, Gonzalez A. Prevalence of Staphylococcus aureus ampollowo and nasal carriage in furuncles and impetigo. Crusted impetigo—vesicles, honey-colored and hematic crusts. Regional lymphadenopathy is common and fever niso occur in severe cases. Other macrolides such as clarithromycin, roxithromycin and azithromycin have the advantage of presenting fewer side effects in the gastrointestinal tract, as well as a more comfortable posology, although with a higher cost.

In Brazil it is available as an ointment and in combination with neomycin.

Bullous impetigo is most common among children aged two to five years. Malnutrition and poor hygiene are predisposing factors.
