| an infected abdominal aortic aneurysm and hepatic abscesses due to streptococcus milleri. | the case of a 78 year old man who presented with fever and hepatic abscesses is reported. he was found to have an infected abdominal aortic aneurysm and the organism cultured was streptococcus milleri. he was treated with an in situ dacron graft and high-dose intravenous penicillin. this may be suitable treatment when gram-positive organisms are involved and there is no gross peritoneal soiling. | 1992 | 20169713 |
| contribution towards developing a new semi-selective medium for streptococcus anginosus group. | the aim of this study was to develop a new selective medium for isolation of streptococcus anginosus group (sag) strains, by adding sulphamethazine and aztreonam as selective agents at mitis-salivarius agar (msa), the medium commonly used for recovery of oral streptococci from oral samples. material and method: the evaluation of mitis-salivarius--sulphamethazine--aztreonam agar (mssaa) for sag selectivity was performed by testing the growth of type strains and laboratory-stored clinical isolates ... | 2009 | 20191907 |

| host cytokine responses distinguish invasive from airway isolates of the streptococcus milleri/anginosis group. | the streptococcus milleri/anginosus group (smg) colonize mucosal surfaces, especially the airways, and are considered to be normal mucosal microbiota; however, they are a major cause of abscesses, pneumonia and pleural empyema. the production of exoenzymes and virulence factors do not correlate with smg pathogenicity. since smg infections are associated with robust inflammatory responses, we hypothesized that host immune responses might distinguish strains associated with asymptomatic carriage a ... | 2014 | 25209732 |
| nas agar is more suitable than mckay agar for primary culture of streptococcus milleri group (smg) fastidious bacteria, s. intermedius in particular. | streptococcus milleri group (smg) is a group of three streptococcal species (s. anginosus, intermedius and constellatus) that act as opportunist pathogens, among others in cystic fibrosis. due to their fastidious character, they are both difficult to cultivate and to differentiate from less pathogenic streptococcal species, therefore being most probably underdiagnosed. semi-selective mckay agar and nas agar were developed to facilitate smg recovery from clinical samples; however, direct comparis ... | 2017 | 27638003 |
| streptococcus milleri and recurrent intra-abdominal abscesses: a case report and literature review. | we report a case of recurrent intra-abdominal abscesses as a postoperative complication following diverticular perforation in which streptococcus milleri (sm) was isolated. sm is evaluated here as a potent pyogenic organism commonly associated with intra-abdominal abscess especially in the postoperative setting. with the commonly adopted conservative management, the challenges of recurrence and prolonged hospital stay experienced in the indexed case as well as many other previous reports are hig ... | 2016 | 27313942 |
