BACKGROUND Standard treatment for pleural infection includes catheter drainage and antibiotics. Tube drainage often fails if the fluid is loculated by fibrinous adhesions when surgical drainage is needed. Streptokinase may aid the process of pleural drainage, but there have been no controlled trials to assess its efficacy. METHODS Twenty four patients with infected community acquired parapneu...

ABST RACT Trueperella pyogenes (formerly Arcanobacterium pyogenes) is a commensal bacterium present on the upper respiratory and urogenital tract mucosa of domestic and wild animals. It is also the most common opportunistic pathogen and isolated from the infections of cattle such as mastitis, metritis, arthritis and pneumonia. The aim of this study was to determine virulence genes (plo, nanH, n...

In Belgium, decreasing macrolide, lincosamide, streptogramins B, and tetracycline use during 1997-2007 correlated significantly with decreasing macrolide-resistant Streptococcus pyogenes during 1999-2009. Maintaining drug use below a critical threshold corresponded with low-level macrolide-resistant S. pyogenes and an increased number of erm(A)-harboring emm77 S. pyogenes with low fitness costs.

In a prospective study of acute pharyngitis in Italian children, 69 (38.3%) of 180 isolates of Streptococcus pyogenes were resistant to macrolides. S. pyogenes was eradicated in 12 (63.1%) of 19 patients with erythromycin-resistant S. pyogenes treated with clarithromycin and in 22 (88%) of 25 patients with erythromycin-susceptible strains. The constitutive-resistant phenotype was correlated wit...

BACKGROUND Acute myocardial infarction is one of the leading causes of death in the elderly, however clinical data reveals a disproportionately lower use of thrombolytics because of fear of complications especially intracranial haemorrhage. Our objective was to evaluate the safety of most commonly used thrombolytic streptokinase in elderly patients presenting with acute myocardial infarction. ...

We studied recanalization of an obstructed left circumflex coronary artery by streptokinase in open-chest anesthetized dogs. Thrombotic occlusion was induced by a 100 microA anodal current selectively delivered to the intimal surface of the vessel. Intracoronary streptokinase (50,000 U) or saline was infused over a 50-min period beginning at either 30 min or 90 min after occlusion. Continuous r...

A search for homologs of the Bacillus subtilis PhoP response regulator in the group A streptococcus (GAS) genome revealed three good candidates. Inactivation of one of these, recently identified as csrR (J. C. Levin and M. R. Wessels, Mol. Microbiol. 30:209-219, 1998), caused the strain to produce mucoid colonies and to increase transcription of hasA, the first gene in the operon for capsule sy...

objective(s): streptococcus pyogenes produces extracellular hyaluronidase enzyme. this enzyme is directly associated with the spread of the organism during infection. the objective of the present study was to clone and express the nucleotide sequence of the enzyme which is involved in hyaluronidase enzymatic activity. materials and methods: the enzymatic region of hyaluronidase gene was detecte...

Here, we report the draft genome sequences of Bacteroides pyogenes JCM 6294(T), JCM 6292, and JCM 10003, which were isolated from a cat and swine and were recently classified into a single species, B. pyogenes. Comparative analyses of these genomes revealed the diversification of B. pyogenes strains isolated from different animals.
