“…Strains of Pseudomonas chengduensis have been found in humans (disease), animals, waste cooking oil, and landfills and have been reported as odor-causing bacteria, similar to other bacteria. However, unlike other bacteria, P. chengduensis has not been reported in human disease cases [34][35][36][37][38][39][40][41][42][43][44]. The last isolate, Staphylococcus warneri, has been found in the environment and animals and has been reported as an odor-causing bacterium in disease reports [45][46][47][48].…”

Odor and discoloration in water-based cutting fluids are caused by the growth of microorganisms and putrefying bacteria. This significantly reduces cutting performance, prevents rust, and deteriorates the working environment. To overcome these drawbacks, we developed a compact air-cooled coaxial dielectric barrier discharge (DBD) with a bubbler. Bacteria and microorganisms living in waste cutting fluids were sterilized by the high concentration of ozone produced under the optimized conditions of the compact air-cooled coaxial DBD. Moreover, it was confirmed that 99.99% of bacteria and microorganisms were completely removed. Ozone was found to not affect property changes such as the composition, concentration, and pH of the water-based cutting fluids. The chromaticity and complex odor of waste cutting liquids were thus found to have been improved by the effects of microorganism and bacterial sterilization. We conclude that the proposed a compact air-cooled coaxial DBD with a bubbler is an efficient method for sterilizing water-based cutting fluids.

“…Such infections can cause necrotic lesions in the oral cavity [ 13 , 14 , 15 ]. However, there have been instances of severe community-acquired Pseudomonas aeruginosa pneumonia resulting in septic shock in immunocompetent patients [ 16 , 17 , 18 , 19 ], with resultant neutropenia [ 20 ] or even death [ 16 , 18 , 20 ]. However, oral manifestations are not commonly reported for these cases.…”

“…It occurs five times more commonly in developing countries as compared to developed countries [ 21 ], and predisposing factors include prolonged antibiotic intake [ 22 ], poor dwelling conditions [ 19 ], and environmental pollution [ 21 , 23 ]. Transmission may occur through the environment, such as through exposure to contaminated water [ 16 , 24 ], and possibly through person-to-person transmission through droplets and aerosols [ 25 , 26 ].…”

Background: There have been no reports of sepsis-induced agranulocytosis causing gingival necrosis in otherwise medically healthy patients to the authors’ best knowledge. Even though there are several case reports of gingival necrosis secondary to medication-induced agranulocytosis, they have not systematically described the natural progression of agranulocytosis-related gingival necrosis. Methods: This paper presents a case report of a 29-year-old female Indian patient with generalised gingival necrosis and constitutive signs of intermittent fever, nausea, and vomiting. She also complained of abdominal pains. Blood counts showed agranulocytosis, and the patient was admitted for a workup of the underlying cause. Parenteral broad-spectrum antibiotics were administered, which brought about clinical resolution. Results: Her gingival necrosis was attributed to sepsis-induced agranulocytosis triggered by Pseudomonas aeruginosa bacteraemia, and upon clinical recovery, spontaneous exfoliation left behind exposed bone. Secondary healing over the exposed alveolar bone was noted after a year-long follow-up, albeit with some residual gingival recession. Conclusions: Oral manifestations of gingival necrosis, when present with concomitant constitutive symptoms, could indicate a serious underlying systemic condition that could be potentially life-threatening if left untreated. Dentists should be cognizant of this possibility so that timely intervention is not delayed.
