alpha-Hemolytic streptococci, variously described as cell-wall deficient (C), L form (L), thiol dependent (O), satelliting (S), pyridoxal dependent (PY), and nutritionally deficient (N), or CLOSPYN, were isolated from patients with endocarditis, brain abscess, subauricular abscess, septicemia, acute and chronic urethritis, recurrent aphthous stomatitis, and fever of undetermined origin. With the aid of satelliting, most of the strains were adapted to grow on a human Mycoplasma growth agar consisting of brain-heart infusion agar fortified with 20% human blood, yeast extract, and arginine. Selected CLOSPYN strains required extensive subculture for only partial reversion to parentallike characteristics. Four of six strains biochemically tested were judged Streptococcus morbillorum. Two were unidentifiable. The CLOSPYN form was relatively inert biochemically, but glucose was converted mainly to lactic acid, with acetic acid also present. Guanine-cytosine values were 39%-43%. Cell wall material was present by transmission electron microscopy (TEM), but its synthesis was uneven on single cells and abnormally thickened on other cells. Closely spaced, incompleted septa occurred in cell chains, which resulted in unusually long chains of flattened cells resembling on TEM a stack of checkers. Mesosomes were frequent, greatly enlarged, convoluted, and elongated. They were often sectioned as circular and laminated, with 2-5 layers. Mesosomes were in close contact with nucleoid bodies, which, in turn, were closely apposed or integral with the cytoplasmic membranes in areas of cross-wall development. Chaotic morphology typifies the group. The inclusion of urinary tract infections is new in the gamut of diseases caused by CLOSPYN streptococci.

Endocarditis is an uncommon presentation of Kingella kingae infection in children. A previously healthy 17 month old child was referred to our emergency department for evaluation of fever lasting eleven days, aphthous stomatitis and a new systolic murmur. Within a few hours of admission, antibiotic therapy was initiated for a presumptive diagnosis of bacteremia and within 24 hours after admission, gram negative coccobacilli were growing in the blood culture. In addition, echocardiography demonstrated a mycotic aneurysm of the ascending aorta with a mobile vegetation. The presumptive diagnosis of Kingella kingae endocarditis was made. Further evaluation by MRI revealed frontal and occipital cerebral infarcts. Due to the presence of presumed septic emboli in conjunction with progressive left ventricular dysfunction, the child was urgently taken to the operating room where aggressive debridement of the infected tissue was performed and the aortic aneurysm was repaired. The patient had an uneventful post-operative course. This case emphasizes the need for a high index of suspicion when evaluating children with community acquired infection. In addition, it also demonstrates the importance of early diagnosis and appropriate treatment of K. kingae endocarditis.
