What are the symptoms of Pseudomonas aeruginosa infection?

Pseudomonas aeruginosa infection often occurs in infants and young children. The symptoms are gangrene and pustular disease, which refers to the presence of purple-red halos around the skin. The contents of the blisters quickly turn into bloody ulcers, followed by black necrotic crusts. In addition, patients may experience body temperature without fever, abdominal distension, hallucinations or fainting, so you need to be vigilant when these similar symptoms occur.

Pseudomonas aeruginosa, also known as Pseudomonas aeruginosa, belongs to the genus Pseudomonas and is an aerobic Gram-negative bacillus. Pseudomonas aeruginosa skin infections often occur in persistently moist damaged areas, especially around the umbilicus of infants, on the surface of burns, and also in macerated webbed toes, external auditory canals, and auricles.

1. Gangrenosum impetigo

Also known as gangrenous ecthyma, it is common in patients with leukemia, severe burns, tri-lineage cell reduction, advanced cancer or certain serious wasting diseases. The clinical features are clusters of blisters surrounded by a purple-red halo. The contents of the blisters quickly become hemorrhagic and rupture to form round ulcers with a black necrotic crust in the center. The damage mainly occurs in the limbs and buttocks. It can cause Pseudomonas aeruginosa sepsis and cellulitis, and may present with maculopapular rash, plaques, and crusts. Severe cases may be accompanied by fever, thirst, abdominal distension, hallucinations and syncope. Gram-positive bacilli were detected in the blisters and Pseudomonas aeruginosa was found in blood culture.

2. Green nail syndrome

The infection is confined to the fingertips and is clinically characterized by nail stripping. The nail stripping area appears light green, and paronychia may occur if the patient comes into contact with water.

3. Otitis externa

Pseudomonas aeruginosa infection is confined to the external auditory canal and accounts for approximately 70% of external otitis, manifesting as swelling, maceration, and pain in the external auditory canal.

4. Pseudomonas aeruginosa toe web infection

The infection is characterized by well-defined macerations in the web of the toes that are sometimes stained green and fluoresce green under a Wood lamp. If the local inflammation worsens, pus or serous secretions may be exuded, accompanied by erythema and edema of the surrounding tissues, and can also be secondary to Candida infection.

Many diseases may show some symptoms in the early stages, so everyone can pay more attention to the health of the body and observe whether there are these abnormal manifestations. Only by timely discovery and timely treatment and resolution measures can the impact of Pseudomonas aeruginosa infection be reduced.
