Impetigo is a common cutaneous infection that is especially prevalent in children. Historically, impetigo is caused by either group A β- hemolytic.

Most species of Pseudomonas aeruginosa are resistant to it. This response may lead to the formation of exfoliative cutaneous eruption, vomiting, hypotension and shock.
Clinical and molecular characteristics of invasive and noninvasive skin and soft tissue infections caused by group A streptococcus. The association is not effective against MRSA. Impetigo in a population over 8. It is less effective against Gram-negative bacteria, but exhibits in vitro activity against Haemophilus influenzae, Neisseria gonorrhoeae, Pasteurella multocida, Bordetella pertussisand Moraxella catarrhalis.
Bullous impetigo is almost universally caused by a single organism, S. Systemic absorption is minimal and the little that is absorbed is rapidly converted to inactive metabolite, hence the reason why there are not oral or parenteral formulations available.
Staphylococci that possess PVL gene cause suppurative cutaneous infections such as abscesses and furuncles. Retapamulin is a semi-synthetic agent derived from an edible mushroom called Clitopilusscyphoides. Staphylococcal infections are present in all age groups.
Its antibacterial action occurs through the inhibition of protein synthesis by binding selectively to bacterial ribosomes. How to cite this article.
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 spectrum of the selected antibiotic must cover staphylococci and streptococci, both for bullous impetigo as well as for crusted impetigo. 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.
The jios would be imprtigo the nares or perineum to normal skin, and later to injured skin.
It occurs in adults and children but rarely in those under two years of age. It is the result of Streptomyces fradiae fermentation. Clinical cure of impetigo with retapamulin is well defined, when compared with placebo. MRSA resistance to mupirocin has already been described. It is not active against bacteria of the normal cutaneous flora and therefore does not alter the skin’s natural defense.
Community-associated methicillin-resistant Staphylococcus aureus and impetigo.
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. Several decades of epidemiological studies indicate that there are some strains of group A streptococci that elicit oropharyngeal infections, but rarely cause impetigo.
The main etiological agent has varied over time. Coagulase negative staphylococci are 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.
Erythromycin, being less expensive, can become the antibiotic of choice for the most impoverished populations.
Toxin-mediated streptococcal and staphylococcal disease. Therefore, concern about MRSA in community-acquired infections, should be greater in the presence of furuncles and abscesses and smaller in impetigo. 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 zmpolloso impetigo. It is also effective, to a lesser extent, against Streptococcus and Propionibacterium acnes.
Mupirocin and fusidic acid are the first choice options. Most Gram-negative microorganisms and yeasts are resistant to it.
J Investig Dermatol Symp Proc. The incidence of allergic reactions is low and cross-allergy has not been seen.
El impétigo (para Adolecentes)
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. Fusidic acid in skin and soft tissue infections. Lancefield classification of streptococci is based on the cell wall’s C carbohydrate antigens, going from A to T.
