Mupirocin and fusidic acid are lmpetigo first choice options. 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.

Diagnosis and treatment of impetigo. Its antibacterial action occurs through the inhibition of protein synthesis by binding selectively to bacterial ribosomes. The isolation of streptococci of groups other than A can mean a secondary infection of preexisting lesions or colonization on cutaneous surface. Thus, benzathine penicillin or those sensitive to penicillinases are not indicated in the treatment of impetigo.

Host factors seem to determine the onset of disease. Neomycin sulfate is active mainly against aerobic Gram-negative bacteria Escherichia coli, Enterobacter aerogenes, Klebsiella pneumoniae, Proteus vulgaris. Toxin-mediated streptococcal and staphylococcal disease.

On the other hand, there is a distinct group of strains that cause cutaneous infection but that do not affect the throat. It works by interfering with bacterial cell wall formation.

Br J Gen Pract. Each lesion measures 1 to 2 cm in diameter and grows centrifugally Figure 4. Acute bacterial skin infections in children. Fusidic acid in dermatology. Scalded skin syndrome usually begins after a localized infection on the conjunctiva, nose, navel or perioral region and more rarely after pneumonia, endocarditis and arthritis.

Bacterial resistance rate is low, around 0. The commercially available formulation is a mixture of neomycin B and C, while framycetin, used in Canada and several European countries, is composed of pure neomycin B. Skin bacteriology and the role of Staphylococcus aureus in infection.

It occurs in adults and children but rarely in those under two years of age. It is active against Gram-positive cocci such as staphylococci and streptococci. It is not active against bacteria of the normal cutaneous flora and therefore does not alter the skin’s natural defense.

It is the result of Streptomyces fradiae fermentation. Crusted impetigo—vesicles, honey-colored and hematic crusts. Cases of infections caused by MRSA in the community were reported in the 80’s, but the importance of this group has increased significantly in recent years. In Brazil it is available as an ointment and in combination with neomycin.

Being a bacteriostatic drug, bacterial eradication may not occur, even after the clinical cure of impetigo. Bacitracin A is the main component of commercial products and is generally formulated as a zinc salt. It is less effective in traumatic lesions and those with abscess formation usually caused by anaerobic bacteria and MRSA. New horizons for cutaneous microbiology: November 15, ; Accepted: Beta-hemolytic streptococcus group A is not commonly observed before two years of age, but there is a progressive increase in older children.

Biofilms are complex and sessile aggregates comprising one zmpolloso more bacterial species associated with an extracellular polymeric substance. Bullous impetigo is most common among children aged two to five years. Regulatory mechanism for exfoliative toxin production in Staphylococcus aureus.

There is a predominance of lesions in exposed areas, especially in the limbs and face Figures 5 and 6.

Community-acquired methicillin-resistant Staphylococcus aureus: The discovery of satellite lesions, caused by self-inoculation, is frequent. Regional lymphadenopathy is common and fever can occur in severe cases. It is less effective against Gram-negative bacteria, but exhibits in vitro activity against Haemophilus influenzae, Neisseria gonorrhoeae, Pasteurella multocida, Bordetella pertussisand Moraxella catarrhalis.

Therefore, concern about MRSA in community-acquired infections, should be greater in the presence of furuncles and abscesses and smaller in impetigo.
