A new 4-h commercial system (API 20S; Analytab Products, Plainview, N.Y.) for the identification of streptococci was compared with the conventional biochemical profile method in the species identification of alpha-hemolytic streptococci. A total of 194 clinical isolates (including 74 isolated from blood cultures, 64 isolated from wound cultures, and 56 isolated from respiratory cultures) and 20...

Obsessive compulsive disorder (OCD) is a neurobiological disease characterized with obsessions and compulsions. Obsessive compulsive disorder occurs with an autoimmune mechanism after Group A β hemolytic streptococcus (GABHS) infection. Tumor necrosis factor (TNF) is an important cytokine, as well as having an important role in the apoptosis mechanism of autoimmune diseases. It is expressed by ...

The patient in septic shock presents an imposing challenge to the physician's clinical skills; therapy must be initiated often before important data are obtained to assure optimal outcome for these very ill patients. For the past several decades the term septic shock has been virtually synonymous with gram-negative sepsis, as this syndrome is most frequently caused by the endotoxin sometimes ex...

Current guidelines and review articles emphasize that clinicians should consider group A beta-hemolytic streptococcus in the diagnosis and management of patients with acute pharyngitis. Recent data suggest that in adolescents and young adults (persons aged 15 to 24 years), Fusobacterium necrophorum causes endemic pharyngitis at a rate similar to that of group A beta-hemolytic streptococcus. On ...

A prospective multicenter study on invasive infections caused by beta-hemolytic streptococci was performed over 6 months and involved 42 centers from 16 cities in Argentina. Among 33 isolates recovered, 9 group G Streptococcus isolates (39.1%) and 2 group C Streptococcus isolates (20%) exhibited resistance to tetracycline and harbored the tet(M) gene. Genealogical analysis revealed that tetracy...

Classification, nomenclature and identification of the Streptococcus anginosus group (SAG) have been historically problematic and unreliable, mainly due to variability in bacteriological characteristics and clinical presentations. This group was first discovered in 1956 by Guthof, in reference to non-hemolytic streptococcal lassification, nomenclature and identification of the Streptococcus ang...

Methods The susceptibility testing was carried out by unified protocol of Kirby-Bauer method (KB) were Streptococcus pneumonia (1699), b-hemolytic streptococci(1428) including GAS (756), GBS (451), GCS (34), GGS (140), and GFS (31) none classified (16), and Viridans streptococc group excluded S. pneumonia isolated from sterile parts (280). The susceptibility testing was assayed by Penicillin E-...

McIlwain (Biochem J. (London), 40, 67, 1946) reported that glutamine, arginine, and urea stimulate glycolysis in resting cells of the hemolytic streptococcus. We have observed an analogous phenomenon in cell-free preparations of a single strain of Streptococcus pyogenes (S23). Our cell-free extracts were prepared by grinding the washed cells from 1,600 ml of an 18 hour broth culture of a nonmuc...

Streptococcus parauberis is a coccoid, nonmotile, alpha-hemolytic, Gram-positive bacterium of the Streptococcaceae family. Streptococcus parauberis strain KCTC11980 was isolated from the kidney of a diseased olive flounder collected from an aquaculture farm on Jeju Island in 2010. The 2.12-Mb genome sequence consists of 44 large contigs in 16 scaffolds and contains 2,214 predicted protein-codin...
