“…The third case was caused by Enterococcus faecalis 3 months after TAVI in a patient with a urinary tract infection, which was the most probable origin of the endocarditis . The fourth case was caused by Histoplasma capsulatum 9 months after TAVI , and the fifth case was caused by Moraxella nonliquefaciens 2 months after implantation . The sixth case was caused by Staphylococcus lugdunensis 19 months after TAVI, but 4 weeks after percutaneous coronary intervention without endocarditis prophylaxis .…”

Few cases of infective endocarditis (IE) as a complication of percutaneous transcatheter aortic valve implantation (TAVI) have been reported. Here, we present a case of IE caused by Streptococcus viridans that occurred 6 months after TAVI with the corevalve revalving system. The patient was successfully treated with antibiotics and was asymptomatic during the 2 years after IE. We also present a review of the literature, including 15 published cases of IE after TAVI.

“…Surgery in these high risk or inoperable patients in general is considered in case of thromboembolic event, abscess, aneurysm, vegetations, uncontrolled infection and heart failure. Surgical replacement of TAVI has been reported in only four patients with zero 30 days mortality (5,19,22,23,25).…”

Prosthetic valve endocarditis after transcatheter aortic valve implantation-diagnostic and surgical considerations

et al. 2016

Prosthetic valve endocarditis (PVE) after transcatheter aortic valve implantation (TAVI) or surgical aortic valve replacement (SAVR) is a potential life threatening complication. Better understanding of the incidence, predictors, clinical presentation, diagnostic measures, complications and management of PVE may help improve TAVI long-term outcome. We report a case of TAVI-PVE in an 80-year-old high risk patient in whom SAVR was successfully performed. We have reviewed literature regarding TAVI-PVE.

“…They were not the dominant species in the airborne bacteria. M. nonliquefaciens is associated with endophthalmitis and pneumonitis with pulmonary abscess (Davis et al 2004;Laukeland et al 2002;Rafiq et al 2011;Rosett et al 1976;Tønjum et al 1991), while F. odoratum causes respiratory and health disorders (Chen et al 2009;Monteil and HarfMonteil 1997;Vancanneyt et al 1996). Workers in WWTPs may be exposed to both these strains through the inhalation of aerosols or by hand-to-mouth contamination.…”

Airborne bacteria emissions from oxidation ditch with rotating aeration brushes were investigated in a municipal wastewater treatment plant in Beijing, China. Microbial samples were collected at different distances from the rotating brushes, different heights above the water surface, and different operation state over a 3-month period (April, May, and June) in order to estimate the seasonal variation and site-related distribution characteristics of the microorganisms present. The concentration of bacterial aerosol was analyzed by culture methods, while their dominant species, genetic structure and diversity were assayed using bio-molecular tools. Results showed that total microbial concentrations were highest in June and lowest in April. The mechanical rotation caused remarkable variation in concentration and diversity of culturable airborne bacteria before and after the rotating brushes. The highest concentration was observed near the rotating brushes (931±129-3,952±730 CFU/m 3 ), with concentration decreasing as distance and height increased. Bacterial community polymerase chain reaction and denaturing gradient gel electrophoresis indicated that diversity decreased gradually with increasing height above the water surface but remained relatively constant at the same height. All dominant bacteria identified by DNA sequence analysis belonged to Firmicutes. Pathogenic species such as Moraxella nonliquefaciens and Flavobacterium odoratum were isolated from the bioaerosols. Due to the serious health risks involved, exposure of sewage workers to airborne microorganisms caused by brush aerators should be monitored and controlled.
