Pseudomonas aeruginosa belongs to the family of Pseudomonodaceae which is one of the most diverse in the microbial world and has very simple growth requirements.
P. aeruginosa is quite concerning because it has the ability to grow in distilled water due to its simple metabolic requirements.
P. aeruginosa has now replaced Staphylococcus aureus as the primary cause of nosocomial (disease originating in a hospital) infections. This is due to several factors including use of antibiotics inappropriately and P. aeruginosas’ ability to acquire antibiotic resistance genes easily.
P. aeruginosa has been implicated in ocular infections due to increased use of extended-wear contact lenses. It has also been associated with open root canals, removal of impacted molars, oral surgery in the soft tissue and bones. In patients with advances periodontitis, P. aeruginosa has been isolated from pockets where previous therapy included antibiotics.
All this is to say, visit your dentist bi-annually for your check-ups and professional cleaning. In addition, maintain a thorough at-home oral hygiene routine which should include brushing twice a day for at least 2.5 minutes, flossing, and rinses with mouthwash.
