“…Infekcyjne zapalenie wsierdzia spowodowane przez paciorkowce z grupy A, B, C lub G, w tym grupę Streptococcus anginus (S. constellatus, S. anignosus i S. intermedius), występuje stosunkowo rzadko [151]. Paciorkowce z grupy A są jednakowo wrażliwe na b-laktamy (MIC ≤ 0,12 mg/l), podczas gdy inne grupy mogą się charakteryzować różnym stopniem oporności.…”

“…IZW spowodowane przez paciorkowce z grupy B historycznie wiązało się z okresem okołoporodowym, ale aktualnie występuje wśród innych dorosłych pacjentów, zwłasz-cza w podeszłym wieku. Paciorkowce z grupy B, C i G oraz S. anginosus powodują powstawanie ropni, co może wymagać dodatkowo interwencji chirurgicznej [151]. Śmiertelność w IZW spowodowanym paciorkowcami z grupy B u pacjentów ze sztuczną zastawką jest bardzo wysoka, dlatego zaleca się leczenie operacyjne [152].…”

“…In a review of 29 patients with infective endocarditis due to S. anginosus group isolates, cardiac surgery was required in 62% of the cases; predictors included acute valve dysfunction and intracardiac abscess. 22 In addition, distant focal suppurative complications requiring surgical drainage were observed in 25% of cases. 22 In the absence of endocarditis or distant focal suppurative complications, bacteremia has a good prognosis.…”

Splenic infarction is a common finding in patients of infective endocarditis due to septic emboli of the spleen. However, the occurrence of acute abdominal pain as an initial manifestation of endocarditis is unusual. Herein, we report a case of splenic infarct and infective endocarditis caused by Streptococcus constellatus cured by antibiotic treatment and valve replacement without the aid of splenic intervention.

“…Neither of the two patients who received beta-lactam antibiotics died. The mortality rate for patients with infective endocarditis is about 16% (9) (14% in cases of infective Streptococcus milleri endocarditis and 25% in cases of infective beta-hemolytic Streptococcus endocarditis [21]). S. equi subsp.…”

Illustration of the Difficulty of Identifying Streptococcus equi Strains at the Subspecies Level through a Case of Endocarditis in an Immunocompetent Man

dWe report a case of endocarditis caused by Streptococcus equi in an immunocompetent patient who was subsequently cured after appropriate antibiotherapy and cardiac surgery. However, it was challenging to identify the strain to the subspecies level, which highlights the necessity of developing reliable molecular tools to discriminate between the subspecies. CASE REPORT In January 2012, a 63-year-old man presented to the emergency room with a 2-week history of low-grade fever but without other symptoms and reported self-treatment with paracetamol. Past medical history included pituitary adenoma, which was treated by surgery in 1989, and a mechanical aortic valve replacement in December 2008 as treatment for severe aortic insufficiency.At admission, he had no fever (37.2°C), was under treatment with paracetamol, and had a pulse rate of 71/min. His blood pressure was 128/91 mm Hg, and oxygen saturation was 97% on air. An erythematous skin rash on his forehead extending to his right infraorbital area, which appeared a few hours before admission, was noted. No other skin lesions were apparent by physical examination. Cardiac auscultation was normal, and no signs of cardiac failure were found. Electrocardiogram revealed a second-degree atrioventricular block, while neurological, abdominal, and respiratory examinations were normal. The thoracic computed tomography scan was normal, transthoracic and transesophageal echocardiographies (TTE and TEE) did not show any vegetation or signs of endocarditis, and the mean transaortic valve gradient was close to 35 mm Hg without pathological regurgitation.Initial laboratory investigations revealed a leukocyte count of 10,100/mm 3 (75% neutrophils) (8,000 to 10,000/mm 3 ), the C-reactive protein concentration was 30 mg/liter (normal, Ͻ4 mg/liter), and his serum electrolyte assay results, troponin level, and international normalized ratio (INR) were normal. On the third day, pyrexia and confusion were observed. Blood cultures were performed daily, and cultures were incubated in a BacT/Alert automated system (Organon Teknika, bioMéri-eux). Aerobic and anaerobic bottles (eight out of nine sets) obtained during the febrile period were positive within 24 h, and Gram-positive coccus chain formation suggestive of Streptococcus was seen upon Gram staining.A subculture of the bacterium was obtained within 24 h of incubation on horse blood agar and on chocolate agar (bioMérieux, Marcy l'Etoile, France). The colonies were 0.5 to 1 mm in diameter, round, mucoid, glistening, nonpigmented, catalase negative, and beta-hemolytic. Gram staining demonstrated thin, short to medium-length, Gram-positive, non-spore-forming cocci suggestive of Streptococcus. The strain was identified as Lancefield group C, and rapid ID 32 Strep and API 20 Strep (bioMérieux) results were Streptococcus equi subsp. zooepidemicus (probability, 99.7%). However, the following phenotypical characteristics led to an identification as Streptococcus equi subsp. ruminatorum: the CAMP reaction was positive, and the strain hydrolyz...

Comparison Between Adult Endocarditis Due to β-Hemolytic Streptococci (Serogroups A, B, C, and G) and Streptococcus milleri<subtitle>A Multicenter Study in France</subtitle>

Abstract: Compared with Sm IE, BHS IE occurs in younger patients with more underlying diseases and fewer underlying cardiopathies and has a more aggressive presentation and evolution.
