Background: Streptococcus pyogenes or Group A streptococcus (GAS) causes several suppurative and non suppurative infections. Since the 1980s there has been re-emergence in the incidence of invasive S. pyogenes infections and rheumatic heart disease all over the world and hence throat carriage has assumed of great importance. Objectives: We carried out this preliminary study to determine the thr...

We present here the draft genome sequence of Streptococcus pyogenes strain M3KCL. The assembly contains 1,864,059 bp in 60 contigs. This strain is an M3 strain close to MGAS315 but produces SpeB. It was isolated from the blood of a human patient with an invasive infection in 2009.

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...

Triphenyltinbenzoate was synthesized using triphenyltinchloride and silver benzoate prepared from sodium benzoate. The structure of the synthetic compound was elucidated by spectral and C, H analysis. The antibacterial activities of the organotin compound were determined against four bacteria namely Escherichia coli (ATCC 25922), Staphylococcus aureus (ATCC 25923), Streptococcus pyogenes (clini...

Trueperella pyogenes is a significant pathogen of livestock, causing diverse diseases, such as mastitis, liver abscessation, and pneumonia. In this study, we have reported the genome sequence of Trueperella pyogenes 2012CQ-ZSH. Moreover, several genes coding for virulence factors were found, such as pyolysin (PYO), nanH, nanP, cbpA, fimC, and fimE.

Streptococcus pyogenes causes a greater diversity of human disease than any other bacterial pathogen. Here, we present the complete genome sequence of the emm type 14 S. pyogenes strain HSC5. This strain is a robust producer of the cysteine protease SpeB and is capable of producing infection in several different animal models.

Historically, Streptococcus pyogenes was a common cause of endocarditis and infected aortic aneurysm. Today, endovascular infections due to this organism have become exceedingly rare. We report the first case of aortic aneurysm infection due to S. pyogenes treated with initial endoluminal repair, review previous reports and discuss current treatment options.

Retapamulin had the lowest rate of spontaneous mutations by single-step passaging and the lowest parent and selected mutant MICs by multistep passaging among all drugs tested for all Staphylococcus aureus strains and three Streptococcus pyogenes strains which yielded resistant clones. Retapamulin has a low potential for resistance selection in S. pyogenes, with a slow and gradual propensity for...

The diethyl ether and ethyl acetate fractions of the peel fruit Solanum incanum. (S. incanum) were analyzed using gas chromatography-mass spectrometry (GC–MS). 105 compounds identified in fraction 75 fraction. Among them, 5 by fragmentation pattern, discussed, compared with NIST database. antibacterial screening was also conducted for bothdiethyl S.incanum four pathogens, two Gram-positive bact...

Electron microscopic observations of Streptococcus pyogenes (strain S43, type 6) treated with trypsin and cetyltrimethylammonium bromide (Cetab) are presented. The concentration of trypsin necessary to remove the M protein antigen was shown to bring about a partial digestion of the cells. The cell protoplasm and protoplasmic membrane were affected. No microscopic changes appeared in the cell wa...
