Streptococcus pseudopneumoniae was described in 2004 as a new human pathogen, acknowledged in a range of clinical infections typically associated to the respiratory tract. This report demonstrates that S. pseudopneumoniae has the potential to cause invasive infection. In blood cultures from three patients, growth of an atypical Streptococcus pneumoniae (non-capsular, non-serotypeable, optochin susceptible under ambient atmosphere and bile-intermediately soluble) was recovered. All three patients had a history of a haematological disease (myelodysplastic syndrome and multiple myeloma) and an apparent origin of infection related to the liver or bile duct. All isolates were genome sequenced and subsequently identified as S. pseudopneumoniae by multi-locus sequence analysis (MLSA). Multi-locus sequence typing (MLST) based on the S. pneumoniae scheme revealed unknown sequence types and the antibiogram and resistome revealed no antibiotic resistance.
