PURPOSE Erythromycin-resistant beta-hemolytic streptococci (BHS) has recently emerged and quickly spread between and within countries throughout the world. In this study, we evaluate the antimicrobial susceptibility patterns and erythromycin resistance mechanisms of BHS during 2003-2004. MATERIALS AND METHODS The MICs of seven antimicrobials were determined for 204 clinical isolates of BHS fr...

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...

BACKGROUND Meningitis is a serious infection. Little is known about the bacterial agents and their antibacterial sensitivity in Nepalese children. OBJECTIVES To study bacteriological agents, clinical profile and immediate outcome in patients admitted to children ward of Patan Hospital with meningitis. METHODS Prospective observational study conducted in paediatric ward of Patan Hospital. Al...

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...

The authors report a case of a 35-year-old man with no known underlying disease who presented with fever, cellulitis with hemorrhagic blebs on the left leg, monoarthricular left knee arthritis, multiple organ failure and septic shock. His clinical syndrome was compatible with toxic shock syndrome and his blood grew alpha hemolytic (viridians) Streptococcus mitis. To our knowledge, there are few...

aim : thereby we aimed to detection of bacterial dna (bactdna) in sbp by polymerase chain reaction (pcr) and its prognostic relevance in cirrhotic patients with culture-negative non-neutrocytic ascites(cnnna).  background: approximately 60% of patients with spontaneous bacterial peritonitis (sbp) are ascites culture negative. methods : of each 77 patients with cirrhosis and ascites, two samples...

1. Hydrochloric acid extracts of Streptococcus haemolyticus contain type-specific, as well as non-type-specific, substances. The precipitates formed by these crude extracts with homologous antibacterial serum are flocculent, while those obtained with heterologous serum are usually disc-like. 2. The type-specific substance may be detected by the use of anti-bacterial sera absorbed with heterolog...
