Answer

Pseudomonal infections (eg, bacteremic pneumonia, sepsis, burn wound infections, meningitis) are associated with an extremely high mortality rate.

Monocular blindness is primarily due to bacterial keratitis, the causes of which include pseudomonal infection. Colonization with B cepacia has been associated with increased morbidity and mortality in patients who are immunocompromised, especially those with CF.

Untreated glanders and melioidosis bloodstream infections are usually fatal within 7-10 days. P aeruginosa bacteremia has an estimated mortality rate exceeding 50% and is associated with fatality rates higher than those associated with other gram-negative bacteremic infections. Pseudomonal pneumonia, especially the bacteremic type, is associated with mortality that typically occurs 3-4 days after the first signs or symptoms of pulmonary or extrapulmonary infection. Ventilator-associated pneumonia (VAP) caused by P aeruginosa is associated with higher mortality rates (estimated to be as high as 68%) than VAPs caused by other infectious organisms. The mortality rate is high for the septicemic form of EG and is approximately 15% for the nonsepticemic form of the disease.
