Abstract:Adult bacterial meningitis caused by viridans streptococci is not uncommon and otopharyngeal infection appears to be an important portal of entry. Clinical manifestations varied according to the different underlying conditions. The results of this study also demonstrate the high incidence of intracranial focal suppuration and cerebral vasculitis concomitant with meningitis. Penicillin remains the treatment of choice for patients with meningitis caused by viridans streptococci. Therapeutic outcome is favorable … Show more
“…It is probable that the viridans streptococci had initially caused the above-mentioned focal infections like sinusitis, which are well known predisposing factors that increase the risk of bacterial meningitis. 14 In the present case there was established maxillary sinusitis, which can be the source of meningitis. However, in a third of these meningitis cases the exact source of infection is not clear.…”
The purpose of this report is to emphasize the importance of the occurrence of S. mitis meningitis in patients with concomitant factors such as older age (>50 years), alcoholism, poor oral hygiene, and maxillary sinusitis.

“…Furthermore, poor oral hygiene might be a risk factor for S. viridans infections. Our patient had strabismus correction eye surgery; to date, there has been no history of meningitis due to S. viridans after an eye operation; however, endophthalmitis and meningitis due to S. pneumonia have been reported 4,10 …”
In bacterial meningitis, the Viridans streptococci group is not considered a prevalent pathogen. In contrast, the S. viridans group may cause endocarditis and fatal infections in immunocompromised children and adults. We report a 5-year-old immunocompetent boy with signs of meningitis. The CSF tested positive for meningitis with streptococcus viridans.
“…However, the initial response to flomoxef was not satisfactory, which may be related to poor penetration of flomoxef into the central nervous system. Patients infected by viridans streptococci have usually had a high incidence of focal suppuration and cerebral vasculitis, but had a consistently favourable prognosis (Lu et al , 2001a, 2002; Yaniv & Potasman, 2000). Only the initial consciousness level and the presence of seizures have been reported to be strongly associated with mortality (Lu et al , 2001b).…”
We report a case of acute purulent meningitis caused by Streptococcus sanguinis after endoscopic ligation for oesophageal variceal haemorrhage in a cirrhotic patient without preceding symptoms of meningitis. Initial treatment with flomoxef failed. The patient was cured after 20 days of intravenous penicillin G. This uncommon infection due to S. sanguinis adds to the long list of infectious complications among patients with oesophageal variceal haemorrhage.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
