Disease relevance of Streptococcus anginosus

• The levels of agreement between the identifications obtained with the commercially available system (Fluo-Card Milleri; KEY Scientific, Round Rock, Tex.) and conventional methods were 98% for 50 Streptococcus anginosus strains, 97% for 31 Streptococcus constellatus strains, and 88% for 17 isolates identified as Streptococcus intermedius [1].
• Haemophilus spp. were isolated more often (P = 0.03) from the BACTEC aerobic Plus/F medium; however, more Streptococcus anginosus organisms (P = 0.02), members of the Enterobacteriaceae family (P < 0.03), and gram-negative anaerobes (P = 0.03) were isolated from the Septi-Chek Release medium [2].
• Laboratory-derived fluoroquinolone-resistant mutants were obtained by serial passage of Streptococcus sanguis and Streptococcus anginosus isolates on agar containing increasing concentrations of old and new fluoroquinolones, ofloxacin and DU-6859a, respectively [3].
• Fibronectin binding by Streptococcus milleri group strains and partial characterisation of the fibronectin receptor of Streptococcus anginosus F4 [4].

High impact information on Streptococcus anginosus

• We first sequenced the complete rpoB gene for Streptococcus anginosus, S. equinus, and Abiotrophia defectiva [5].
• Doxycycline resistance was found in 5.7% of the strains and occurred most frequently in Streptococcus anginosus [6].
• The enzyme that produces hydrogen sulfide from L-cysteine was purified from Streptococcus anginosus [7].
• The binding of Fn to Streptococcus anginosus F4 was studied in more detail [4].
• HKU4T was identified by the Vitek system (GPI), API system (20 STREP) and ATB system (ID32 STREP) as 99 % Streptococcus intermedius, 51.3 % S. intermedius and 99.9 % Streptococcus anginosus, respectively [8].

Chemical compound and disease context of Streptococcus anginosus

• lcd from Streptococcus anginosus encodes a C-S lyase with alpha,beta-elimination activity that degrades L-cysteine [7].
• Homocysteine biosynthesis pathways of Streptococcus anginosus [9].
• A gene (cgs) encoding cystathionine gamma-synthase was cloned from Streptococcus anginosus, and its protein was purified and characterized [9].
• The plasmid-free Streptococcus anginosus F22 contained a conjugative element, Tn3705, encoding resistance to erythromycin (Emr) and tetracycline-minocycline (Tcr-Mnr) [10].
• The frequent occurrence of Streptococcus gordonii and Streptococcus anginosus in the albumin cultures is explained by their ability to utilize arginine as an energy source for growth [11].

Gene context of Streptococcus anginosus

• Detection of Streptococcus anginosus from saliva by real-time polymerase chain reaction [12].
