“…There is no gold standard for the identification of SAG. Cultivation methods and the available biochemical test are not sufficient for precise identification of the species, therefore it is necessary to use molecular techniques ( Wenzler et al, 2015 ; Kragha, 2016 ). Among them, two 16S rRNA real-time PCR assays were developed.…”

“…As described above, head and neck infections are caused by SAG, however, the routes of bacterial spread are poorly explored ( OPEN QUESTION 3 ). Among the routes considered for brain infection are contiguous infection, hematogenous spread, direct implant, trauma or neurosurgery, and peripheral nerves ( Kragha, 2016 ).…”

The Clinical View on Streptococcus anginosus Group – Opportunistic Pathogens Coming Out of Hiding

Three distinct streptococcal species: Streptococcus anginosus, Streptococcus intermedius, and Streptococcus constellatus, belonging to the Streptococcus anginosus group (SAG), also known as Streptococcus milleri group, have been attracting clinicians and microbiologists, not only as oral commensals but also as opportunistic pathogens. For years they have been simply classified as so called viridans streptococci, and distinct species were not associated with particular clinical manifestations. Therefore, description of SAG members are clearly underrepresented in the literature, compared to other medically relevant streptococci. However, the increasing number of reports of life-threatening infections caused by SAG indicates their emerging pathogenicity. The improved clinical data generated with the application of modern molecular diagnostic techniques allow for precise identification of individual species belonging to SAG. This review summarizes clinical reports on SAG infections and systematizes data on the occurrence of individual species at the site of infection. We also discuss the issue of proper microbiological diagnostics, which is crucial for further clinical treatment.

“…Cerebritis may occur for hematogenous spread, direct posterior sinonasal spread, perineural spread, after trauma or as neurosurgical complication; however, from 15% to 30% of brain infections are classified as cryptogenic if the source cannot be found [ [36] , [37] , [38] , [39] ]. Cerebritis presents as an indistinct region of acute inflammation in the brain tissue characterized by enhanced blood vessel permeability in the absence of neo-angiogenesis [ 40 , 41 ].…”

Brain Abscesses in Crohn’s Disease as a Complication of Infliximab Therapy

Infliximab therapy is highly effective in the treatment of Crohn's disease. Infliximab-induced immunosuppression increases the risk for various infections, including opportunistic infections. We describe a case of brain abscesses as a complication of infliximab therapy in a 65-year-old man. It was elucidated that the brain abscesses developed from the presumed hematogenous spread of bacteria from recently treated paraspinal abscesses. Close attention should be given to patients on infliximab therapy presenting with any neurological sign or symptom to allow for timely diagnosis and prompt management of a potential central nervous system infection.
