This response may lead to the formation of exfoliative cutaneous eruption, vomiting, hypotension and shock. The resulting superficial ulceration is covered with purulent discharge that dries as an adhering and yellowish honey-colored crust.

Bullous impetigo is almost universally caused by a single organism, S. In studies conducted over the past three decades, there has been a resurgence of S. Fusidic acid is highly effective against S.

Immunosuppression and tissue damage are considered important in the pathological process genesis, impeyigo the ability to produce coagulase, leukocidin and toxin appears to be the same in the carrier’s normal flora and in bacteria isolated from cutaneous lesions. Staphylococcal strains that are resistant to erythromycin will also be resistant to clarithromycin, roxithromycin and azithromycin. Impetigo in a population over 8.

On the other hand their use is not discouraged, because they do not seem to increase bacterial resistance. ampolloo

The discovery of satellite lesions, caused by self-inoculation, is frequent. Bullous impetigo —desquamation collarette and flaccid blisters.

Malnutrition and poor hygiene are predisposing factors. Dosage of antistreptolysin O may not be useful for fn infections since its titles do not increase satisfactorily.


The presence of MRSA as impetigo’s causative agent in non-hospitalized patients is considered unusual and with heterogeneous distribution.

Being a bacteriostatic drug, bacterial eradication may not occur, even after the clinical cure of impetigo. Crusted impetigo can occur in normal skin or impetiginisation may appear over a previous dermatosis such as atopic dermatitis, contact nis, insect bites, pediculosis and scabies. Retapamulin is a semi-synthetic agent derived from an edible mushroom called Clitopilusscyphoides. Therefore, concern about MRSA in community-acquired infections, should be greater in the presence of furuncles and abscesses and smaller in impetigo.

Diagnosis and treatment of impetigo. Rather, glomerulonephritis may result enn streptococcal cutaneous or upper respiratory tract infections, but the skin is amlolloso main previous site.

It is also effective, to a lesser extent, against Streptococcus and Propionibacterium acnes. Clinico-bacteriological study of pyodermas in children. It is active against Gram-positive cocci such as staphylococci and streptococci. It is particularly important in the neonatal period, starting usually after the second week of life, although it can be present at birth in case of premature membranes rupture.

Thus, their path goes from normal skin to injured skin and may subsequently reach the oropharynx. Regulatory mechanism for exfoliative toxin production in Staphylococcus aureus.

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.

Other phage types involved are 3A, 3C and Scalded skin syndrome usually begins after a localized infection on the conjunctiva, nose, navel or perioral region and more rarely after pneumonia, endocarditis ampollodo arthritis. 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.


It works by interfering with bacterial cell wall formation.

In Brazil it is available as an ointment and in combination with neomycin. Clinical, bacteriological, toxicological and sensitivity to antibiotics studies. It is not active against bacteria of the normal cutaneous flora and therefore does not alter the skin’s natural defense. Services on Demand Journal. Sensitized patients may cross-react when exposed to other topical or systemic aminoglycosides. Bacterial resistance rate is low, around 0.

It is less effective in impetgo lesions and those with abscess formation usually caused by anpolloso bacteria and MRSA. Neomycin sulfate is an antibiotic of the aminoglycoside group most commonly used in topical form.

On the other hand, there is a distinct group of strains that cause cutaneous infection but that do not affect the throat. Most species of Pseudomonas aeruginosa are resistant to it. Impetigo, a reassessment of etiology and therapy. Streptococci isolated from various skin lesions: It can eradicate S.

Lancefield classification of streptococci is based on the cell wall’s C carbohydrate antigens, going from A to T. Impetigo in the French Guiana. New horizons for cutaneous microbiology: Topical agents for impetigo therapy are reviewed. Its actions against most Gram-positive bacteria niks limited.

Gram-negative bacilli are resistant to fusidic acid.
