Endocarditis Due to Neisseria mucosa

Native valve endocarditis with persistent embolization due to Neisseria mucosa

“…This case corresponds to cases of N. mucosa endocarditis in the literature, with the exception of the aortic valve involvement. Only one previous case showed certain aortic valve involvement [4] and, recently, another patient had possible involvement of this valve [5]. Non‐gonococcal, non‐meningococcal Neisseria species existing as respiratory commensals in humans can occasionally cause serious infection, not only in immunocompromised hosts but also in immunocompetent individuals, as in our case.…”

Endocarditis due to Neisseria mucosa after tongue piercing

“…are normal inhabitants of the upper respiratory tract in human beings. Although these bacteria are regarded as having low pathogenicity, Neisseria mucosa has been reported to cause serious infections such as endocarditis [1–5]. We report a case of infective endocarditis due to N. mucosa that probably resulted from tongue piercing.…”

“…Since N. mucosa may have varying susceptibility to penicillin [2], fluoroquinolones such as ciprofloxacin have been used [3].…”
