Pseudomonas guariconensis Necrotizing Fasciitis, United Kingdom

We describe a case of necrotizing fasciitis in the United Kingdom in which Pseudomonas guariconensis was isolated from multiple blood culture and tissue samples. The organism carried a Verona integron-encoded metallo-beta lactamase gene and evidence of decreased susceptibility to beta-lactam antimicrobial agents. Clinicians should use caution when treating infection caused by this rare pathogen.
