[Pneumonia complicated by bacteremia with Stomatococcus mucilaginosus].

A rare strain of Stomatococcus mucilaginosus (formerly Micrococcus) was isolated from blood of a patient after pneumonia, which was causing an enlargement of lymph nodes and groin fistula. Chemical composition of cell wall of this microorganism (analysis of amino acids and diagnostically important sugars), elementary composition of lipids (fatty acids, phospholipids and glycolipids) and molar percentage of guanine and cytosine (%GC), were determined. Results completely agreeable with results published elsewhere were obtained which resulted in reclassification of this species (Kocur (1982, Int. J.Sys.Bacterial. 32, 374-377)). This case indicates that some relative pathogens require modern diagnostic methods and when not recognized in cases of acquired or directed immunosuppression can create a serious threat.
