Impetigo Contagiosa is primarily caused by which bacteria?

Impetigo Contagiosa is primarily caused by Staphylococcus and Streptococci bacteria. This condition is a highly contagious skin infection that is often characterized by the formation of red sores, usually around the nose and mouth, which can rupture, ooze, and develop a yellow-brown crust. The causative agents, Staphylococcus aureus and Streptococcus pyogenes, are both adept at colonizing the skin, particularly when there are abrasions or other breaks in the skin barrier.

The presence of these bacteria can be exacerbated by factors such as poor hygiene, warm and humid weather, and close contact with infected individuals, making it crucial to manage outbreaks and educate about proper hygiene practices. This understanding of the bacteria involved helps in effectively diagnosing and treating the infection, as well as implementing preventive measures in community settings, especially among children who are commonly affected.

In contrast, the other answers list bacteria or factors that do not relate to the primary causative agents of Impetigo Contagiosa. For instance, Escherichia coli primarily affects the gastrointestinal tract and is not associated with skin infections like impetigo. Pseudomonas aeruginosa is known for causing infections in wounds and burns, but it
