Pseudomonas

A genus of gram-negative, nonsporeforming, rod-shaped bacteria. Motile species possess polar flagella. They are strictly aerobic, but some members do respire anaerobically in the presence of nitrate. Some species produce acids oxidatively from carbohydrates; none is fermentative and none photosynthetic.

Members of the genus Pseudomonas cause a variety of infective diseases; some species cause disease of plants. One species, P. mallei, is a mammalian parasite, and is the causative agent of glanders, an infectious disease of horses that occasionally is transmitted to humans by direct contact. Pseudomonas aeruginosa is the most significant cause of hospital-acquired infections, particularly in predisposed patients with metabolic, hematologic, and malignant diseases. The spectrum of clinical disease ranges from urinary tract infections to septicemia, pneumonia, meningitis, and infections of postsurgical and posttraumatic wounds. See Meningitis, Pneumonia

Around 0.3 million people die annually because of burn wounds around the globe with nosocomial infections contributing in 50% of these deaths.1 Gram negative, non-spore forming organism, Pseudomonas aeruginosa is responsible for 10-20% hospital acquired infections and causes 40-75% mortality in burn patients.2 Broad spectrum antimicrobial drugs, fluoroquinolones (FQn), are commonly suggested against pseudomonal infections.3 Misuse of FQn has led to an increase in bacterial resistance due to chromosomal mutation in DNA gyrase (gyr A and gyr B genes) and topoisomerase IV or changes in expression of genes controlling transport of FQns.4 Another important acquired mechanism of FQn resistance is Qnr genes.

The researchers found that 58 percent of the 363 outbreaks with confirmed infectious etiology were caused by Cryptosporidium, 16 percent by Legionella, and 13 percent by Pseudomonas. Overall, 24,453 cases were identified in the 363 outbreaks; 89, 4, and 3 percent were caused by Cryptosporidium, Pseudomonas, and Legionella, respectively.
Of the 157 hotel-related outbreaks, 94 had a confirmed infectious etiology according to the report, 40 were caused by Pseudomonas, 29 by Legionella, and 17 by Cryptosporidium.
