Impetigo contagiosa--etiology in Iraq

Area of Science:

• Dermatology
• Microbiology
• Infectious Diseases

Background:

• Impetigo contagiosa is a common bacterial skin infection.
• Staphylococci and streptococci are typically implicated in impetigo.
• The etiological role of other bacteria requires further investigation.

Purpose of the Study:

• To bacteriologically investigate 200 cases of impetigo contagiosa.
• To identify etiological agents beyond common staphylococci and streptococci.
• To assess antibiotic sensitivity profiles for treatment guidance.

Main Methods:

• Bacteriological culture and isolation from 200 impetigo contagiosa cases.
• Identification of bacterial species, including Gram staining and biochemical tests.
• Antibiotic sensitivity testing on 96 isolates against various antimicrobial agents.

Main Results:

• Staphylococci and streptococci were commonly isolated, as expected.
• Pure cultures of gram-positive diplococci were identified in 37 out of 200 cases (18.5%).
• Antibiotic sensitivity data for 96 cases were analyzed and are presented.

Conclusions:

• Gram-positive diplococci represent a potential, though less common, causative agent in impetigo contagiosa.
• Understanding the bacteriology and antibiotic sensitivities is crucial for effective impetigo management.
• Further research into the specific role and optimal treatment of gram-positive diplococci in impetigo is warranted.
