Which is NOT a characteristic of Pseudomonas aeruginosa infection?

Pseudomonas aeruginosa is a type of bacterium known for causing various infections, particularly in those with weakened immune systems. The key characteristic making the chosen answer accurate is that Pseudomonas aeruginosa is a bacterial infection, not a viral infection. This distinction is crucial because bacterial and viral infections differ fundamentally in their structure, replication, treatment, and the type of immune response they elicit.

The organism can cause symptoms such as itching and can lead to discoloration of infected areas, which might appear green or black due to pigments produced by the bacteria. Thus, the characteristics related to itching and color appearance are consistent with the behavior of this bacterium during infection and are important for identification and understanding of the infection. Understanding these aspects helps in recognizing Pseudomonas aeruginosa infections and developing appropriate treatment plans, as they typically require antibiotics rather than antiviral medications.
