INTRODUCTION Organisms of the Streptococcus milleri group consists of Streptococcus intermedius, Streptococcus constellatus, and Streptococcus anginosus. Though they are commonly associated with abscesses, bacteremia with subsequent septic shock and mortality is infrequent. CASE PRESENTATION We report a case of a 27-year-old Chinese man who presented with Streptococcus constellatus bacteremia...

INTRODUCTION AND OBJECTIVES Published case series on Streptococcus viridans endocarditis are scarce and outdated. The aims of our study were multiple: to analyze the profile of the Streptococcus viridans endocarditis, to compare it with other types of left-sided endocarditis and with cases caused by Staphylococcus aureus, and to determine predictors of poor outcome in Streptococcus viridans end...

Streptococcus gallolyticus is a microorganism belonging to the Streptococcus bovis I group isolated in humans, bovines and equines pigeons, among other animals. Streptococcus bovis is a Streptococcus strain found in the rumen, and has been isolated in the milk of animals with mastitis. The authors describe a case of an adult immunocompetent patient with underlying valvular heart disease, with b...

background and aims. streptococcus mutans is the main pathogenic agent involved in dental caries, and may be eliminated using mouthwashes. the objective of this study was to compare the effects of fluoride, chlorhexidine, and fluoride-chlorhexidine mouthwashes on salivary s. mutans count after two weeks of use and determine the prevalence of their side effects on the oral mucosa. materials and ...

meningitis, pneumonia, and sepsis in newborns and young infants (age < 60 days) are the main causes of childhood mortality in developing countries. even though streptococcus pneumonia is the most commonly detected microorganism in pediatric bacterial meningitis, it is rare in newborn infants. the following article reports a case of pneumococcal meningitis that was detected early in a newborn in...

conclusions it should be kept in mind that the oral flora bacterium s. anginosus may cause transient bacteremia and deep-seated organ abscesses in immunodeficient patients with poor oral hygiene. such patients with intra-abdominal abscesses should be treated with antibiotics and surgery. introduction the streptococcus anginosus group of bacteria are low-virulence bacteria existing as commensals...

Acute pharyngo-tonsillitis caused by beta-haemolytic group A Streptococcus is a common disease in childhood. Epithelial cells are the initial sites of the host invasion by group A Streptococcus. Although group A Streptococcus has been considered an extracellular pathogen, recent studies have demonstrated that strains of this bacterium can internalize into epithelial cells both in vitro and in v...

1. In infections with streptococcus in man, such as acute septic endocarditis, and tonsillitis, there is produced a powerful opsonic immunity. 2. This opsonic immunity is effective towards the streptococcus which has caused infection but may be ineffective in the presence of streptococcus from other sources. 3. Little benefit can be expected from streptococcus vaccines unless they are prepared ...
