How does Pseudomonas aeruginosa cause pneumonia?

Pseudomonas aeruginosa pneumonia is commonly acquired in the ICU because the organism flourishes in moist environments such as sinks, nebulizers, and respiratory and bronchoscopy equipment. It is thus commonly termed ventilator-associated pneumonia.

What does Pseudomonas aeruginosa look like?

Pseudomonas aeruginosa is a Gram-negative, rod-shaped, asporogenous, and monoflagellated bacterium. It has a pearlescent appearance and grape-like or tortilla-like odour. P. aeruginosa grows well at 25°C to 37°C, and its ability to grow at 42°C helps distinguish it from many other Pseudomonas species.

How is Pseudomonas pneumonia treated?

Pseudomonas infection can be treated with a combination of an antipseudomonal beta-lactam (eg, penicillin or cephalosporin) and an aminoglycoside. Carbapenems (eg, imipenem, meropenem) with antipseudomonal quinolones may be used in conjunction with an aminoglycoside.

Why is Pseudomonas so bad?

Pseudomonas is a type of bacteria that can cause lung infections. It mainly affects people who already have a lung condition or who have a problem with their immune system. It doesn’t respond to commonly-used antibiotics, which means infections can be hard to treat.

How long do you treat Pseudomonas pneumonia?

The conventional therapy (ie, an aminoglycoside and a beta-lactam agent with antipseudomonal activity) is needed for at least 4 weeks to treat localized infections and 6-8 weeks or longer to treat extensive disease.

Where can I find photos of Pseudomonas aeruginosa?

What kind of bacteria causes pneumonia in humans?

Pneumonia caused by bacteria Pseudomonas aeruginosa, computer illustration. P. aeruginosa is a Gram-negative bacterium which causes multiple antibiotic resistant nosocomial (hospital-acquired) infections of different location, including pneumonia, osteomyelitis, peritonitis and wound infections.

Which is common cause of community acquired pneumonia ( CAP )?

Pseudomonas aeruginosa is an uncommon cause of community-acquired pneumonia (CAP), but a common cause of hospital-acquired pneumonia. Controversies exist for diagnostic methods and antibiotic therapy.

Is the incidence of P aeruginosa overestimated?

We present circumstantial evidence that the incidence of P aeruginosa has been overestimated for hospital-acquired pneumonia and reflex administration of empirical antipseudomonal antibiotic therapy may be unnecessary.
