A 26-year-old healthy patient had a fever and chest pain three days after nasal carbon dioxide (CO2) laser surgery for chronic and allergic rhinitis. In the emergency room, he was diagnosed as a right pneumothorax and managed as outpatients with oral antibiotic therapy and close follow-up. Six days later, in follow-up clinic, his presenting signs and symptoms included right chest pain, tachypnoea and elevated levels of white blood cell count and C reactive protein. He was diagnosed as septic pulmonary embolism (SPE) by the detection of multiple nodules with cavitation on chest CT. Culture of pleural fluids showed Pseudomonas aeruginosa. Intravenous antibiotic treatment and drainage of the pleural effusion improved his condition. Since SPE occurred after nasal CO2 laser surgery in this case, careful attention should be paid to infectious complications of nasal CO2 laser surgery.

“…The production of an inducible chromosomal β-lactamase called AmpC contributes to Pseudomonas resistance to most penicillins and to first- and second-generation cephalosporins (such as cefoxitin and cefuroxime). In P. aeruginosa , de-repression of this gene can result in resistance to antipseudomonal penicillins, oxyiminocephalosporins, and cefepime [ 27 , 28 ]. Accordingly, among several β-lactamase genes searched, only the chromosomal class C β-lactamase gene bla AmpC was detected in two P. koreensis isolates from urban wastewater treatment plants in Italy, showing low susceptibility to several β-lactams [ 29 ].…”

Pseudomonas fluorescens Complex and Its Intrinsic, Adaptive, and Acquired Antimicrobial Resistance Mechanisms in Pristine and Human-Impacted Sites

Pseudomonas spp. are ubiquitous microorganisms that exhibit intrinsic and acquired resistance to many antimicrobial agents. Pseudomonas aeruginosa is the most studied species of this genus due to its clinical importance. In contrast, the Pseudomonas fluorescens complex consists of environmental and, in some cases, pathogenic opportunistic microorganisms. The records of antimicrobial-resistant P. fluorescens are quite scattered, which hinders the recognition of patterns. This review compiles published data on antimicrobial resistance in species belonging to the P. fluorescens complex, which were identified through phylogenomic analyses. Additionally, we explored the occurrence of clinically relevant antimicrobial resistance genes in the genomes of the respective species available in the NCBI database. Isolates were organized into two categories: strains isolated from pristine sites and strains isolated from human-impacted or metal-polluted sites. Our review revealed that many reported resistant phenotypes in this complex might be related to intrinsic features, whereas some of them might be ascribed to adaptive mechanisms such as colistin resistance. Moreover, a few studies reported antimicrobial resistance genes (ARGs), mainly β-lactamases. In-silico analysis corroborated the low occurrence of transferable resistance mechanisms in this Pseudomonas complex. Both phenotypic and genotypic assays are necessary to gain insights into the evolutionary aspects of antimicrobial resistance in the P. fluorescens complex and the possible role of these ubiquitous species as reservoirs of clinically important and transmissible ARGs.

Pseudomonas stutzeri is distributed widely in the environment, and occupies different ecological niches. However, it is found in clinically relevant infections as an opportunistic pathogen. Isolation of P. stutzeri from an odontogenic inflammatory cyst is an uncommon microbiological finding that has not been reported to date. In the case presented here, the bacterium was isolated from surgical material obtained from excision of an inflammatory odontogenic cyst located in the tooth 1.2, and presenting with concomitant pulp necrosis. Complementary techniques such as radiographs, CAT scans, and histopathological and microbiological studies were used to establish definitive diagnosis. The obtained results allowed classifying the process as an inflammatory cyst infected by P. stutzeri. Biotyping and characterization of the susceptibility profile of the isolated strain allowed adjusting the antibiotic therapy more specifically. The microbiological studies allowed establishing the etiology of the infectious process, adjusting the treatment plan, and re-establishing tissue integrity.
