Pseudomonas aeruginosa

Pseudomonas aeruginosa is a gram-negative aerobic rod belonging to the bacterial family Pseudomonadaceae. It is a free-living bacterium, commonly found in soil and water, which is why it has a predilection for growth in moist environments.

P. aeruginosa is an opportunistic pathogen, meaning that it exploits some break in the host defenses to initiate an infection. It is highly adaptable and resilient, and is highly resistant to many common antibiotics.

P. aeruginosa causes localized or systemic disease in young poultry and omphalitis and yolk sac infections in newly hatched chicks. It also been known to cause respiratory infections (including sinusitis), eye infections (keratitis and kratoconjunctivitis), and septicemia. Young, severely stressed, and immunodeficient birds are most severely effected by P. aeruginosa, although birds of all ages are susceptible.
