This study showed that streptococcal L forms could not be isolated from children who were either carriers of group A streptococci or had disease due to this pathogen. It was possible to induce L colony formation in 15 strains of group A. Streptococcal bacteriophages were demonstrated in 20% of group A streptococci isolated from school children who were carriers, but did not have clinical eviden...

Non-rheumatic Streptococcal Acute Myocarditis, also known as Strep Pharyngitis Acute Myocarditis (SPAM) occurs in young adults, typically within five days of the initial streptococcal pharyngitis, and is characterized by typical cardiac symptoms, abnormal electrocardiography, and elevated cardiac biomarkers in the absence of obstructive coronary artery disease. Patients may also report myalgias...

BACKGROUND There has not been a comprehensive, multi-centre study of streptococcal peritonitis in patients on peritoneal dialysis (PD) to date. METHODS The predictors, treatment and clinical outcomes of streptococcal peritonitis were examined by binary logistic regression and multilevel, multivariate poisson regression in all Australian PD patients involving 66 centres between 2003 and 2006. ...

A 761-bp portion of the tuf gene (encoding the elongation factor Tu) from 28 clinically relevant streptococcal species was obtained by sequencing amplicons generated using broad-range PCR primers. These tuf sequences were used to select Streptococcus-specific PCR primers and to perform phylogenetic analysis. The specificity of the PCR assay was verified using 102 different bacterial species, in...

G ROUP A streptococcal infection initiates acute rheumatic fever; rheumatic valvular heart disease is a sequela that develops during or subsequent to the acute rheumatic episode. The mechanism by which the preceding streptococcal infection produces the arthritic and constitutional symptoms and valvular heart disease is unknown. Regardless of the mechanism involved, there is little doubt that pr...

The levels of streptococcal antibody titers in populations with or without rheumatic fever from an area with a relatively high incidence of rheumatic fever and an area with a low incidence of this disease were compared. Streptococcal antibody titers were determined for two populations, each of which included children without rheumatic fever (nonrheumatic children) and rheumatic fever patients. ...

Erythema nodosum (EN) has been associated with various infectious and noninfectious diseases. A total of 39 EN patients seen between May 2005 and February 2012 were evaluated retrospectively in this study. The etiology of EN was established in 22 of the 39 children (56.4%). Streptococcal infection was the most common cause (23%), followed by tularemia (10.2%) and tuberculosis (latent tuberculos...

This study investigated the inhibitory effect of probiotic Enterococcus faecium WB2000 on biofilm formation by cariogenic streptococci. The ability of E. faecium WB2000 and JCM5804 and Enterococcus faecalis JCM5803 to inhibit biofilm formation by seven laboratory oral streptococcal strains and 13 clinical mutans streptococcal strains was assayed. The Enterococcal strains inhibited biofilm forma...

While group C beta hemolytic streptococcal infections are uncommon in humans, group C beta hemolytic streptococcal pneumonia is exceedingly rare. To the best of our knowledge, only 2 cases of necrotizing pneumonia caused by group C beta hemolytic streptococcus have been reported in the past. Thus, we are reporting a rare case of necrotizing group C beta hemolytic streptococcal pneumonia in a y...

In the past decade there has been renewed interest in psychiatric and movement dis-interest in psychiatric and movement disorders that develop in the context of orders that develop in the context of streptococcal infection. There is increasing streptococcal infection. There is increasing evidence that these disorders are auto-evidence that these disorders are auto-immune and are mediated by ant...
