BACKGROUND
Streptococcus acidominimus resembles Streptococcus viridans, but they can now be differentiated by phenotypic studies. Only a single previous case of pneumonia, pericarditis, and meningitis has been reported.
CASE DESCRIPTION
We recently encountered a patient with brain abscess from which S acidominimus was isolated after initially being recorded as S viridans. Because 49% of all S viridans isolated from abscesses are resistant to beta-lactam antimicrobials, speciation is important as well as in vitro sensitivity testing. Streptococcus acidominimus is ordinarily sensitive to beta-lactams, and the use of ceftriaxone for 6 weeks successfully resulted in cure of the brain abscess.
CONCLUSION
The use of speciation in treatment of S viridans should improve clinical outcomes.
背景
嗜酸微球菌与草绿色链球菌相似，但现在可通过表型研究加以区分。此前仅报道过一例肺炎、心包炎和脑膜炎病例。
病例描述
我们最近遇到一名脑脓肿患者，最初被记录为草绿色链球菌，后从中分离出嗜酸微球菌。由于从脓肿中分离出的所有草绿色链球菌中有49%对β-内酰胺类抗菌药物耐药，菌种鉴定以及体外药敏试验都很重要。嗜酸微球菌通常对β-内酰胺类敏感，使用头孢曲松治疗6周成功治愈了脑脓肿。
结论
在草绿色链球菌治疗中进行菌种鉴定应能改善临床结果。
