Types and symptoms of Pseudomonas aeruginosa infection

Pseudomonas aeruginosa infection is actually a kind of bacteria. This kind of bacteria infection often occurs in some moist areas, such as the burned surface around the baby's belly button, or the external auditory canal, etc. Therefore, we also need to pay attention to understand its different types and correct treatment.

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.

5. Pseudomonas aeruginosa folliculitis

Follicular papules, blisters, and pustules occur on the skin due to bathing in water contaminated by Pseudomonas aeruginosa, and are also called bathing pool folliculitis. The patient suffers from itching, which may be accompanied by varying degrees of low-grade fever, fatigue, headache, myalgia, drowsiness and gastrointestinal symptoms. The course of the disease is about 7 days.
