IN VITRO EFFECT OF STATINS ON STREPTOCOCCUS MUTANS, STREPTOCOCCUS SANGUIS, AND STREPTOCOCCUS SALVARIUS
Objectives: Cardiovascular disease (CVD), including heart attack, angina, and stroke, is ranked as the number one cause of mortality world wide. High blood cholesterol is linked to CVD and is an important risk factor. Statins – cholesterol lowering drugs- are first choice drugs for reducing the …

Studies on the genus streptococcus
… 33-42% (Diebel and Seeley, 1974).</p> The genus Streptococcus includes a large number of saprophytic, pathogenic and non pathogenic species. Many of these bacteria are members of the normal body flora. However, man is very susceptible to the pathogenic members, and no organ in the body is …

Investigating galactose metabolism in Streptococcus pneumoniae
Streptococcus pneumoniae is a formidable human pathogen. Responsible for between 1 and 2 million deaths annually, the pneumococcus makes a major contribution to global morbidity and mortality. In order to cause disease, the pneumococcus must first colonise the human nasopharynx. This colonisation …

Streptococcus pyogenes - a manipulator of human defences
Streptococcus pyogenes is a major human pathogen with more than 500 000 casualties annually of which at least 163 000 are due to invasive infections. The remainder is due to post-streptococcal complications with rheu¬matic heart disease constituting the majority. S. pyogenes also causes milder …

Genomic diversity in naturally transformable Streptococcus pneumoniae
Infections due to Streptococcus pneumoniae (the pneumococcus) remain a substantial source of morbidity and mortality in both developing and developed countries despite a century of research and the development of effective therapeutic interventions (such as antibiotic therapy and vaccination). The …

Characterisation of Streptococcus pneumoniae opacity phase variation
Streptococcus pneumoniae (the pneumococcus) is a common nasopharyngeal commensal in humans that can invade deeper tissues causing a range of diseases, resulting in significant global morbidity and mortality. Any given strain of S. pneumoniae can undergo phase variation between two different colony …

Biofilm formation and virulence of Streptococcus pneumoniae
S. pneumoniae is a genetically diverse species which complicates attempts to associate a given clonal lineage or serotype with propensity to cause disease; as well as in the identification of specific molecular determinants of distinct virulence phenotypes. Formation of biofilms is an important …

Geographic Migration and Evolution of Streptococcus pneumoniae
Streptococcus pneumoniae (the pneumococcus) is a human-obligate, opportunistic bacteria. It resides asymptomatically in the nasopharynx of both children and adults. It occasionally goes on to cause local disease such as otitis media, or severe invasive disease as with pneumonia and meningitis. It …

Genomic insights into Group A Streptococcus pathogenesis
Group A Streptococcus (GAS) is a bacterium responsible for invasive and non-invasive infections in humans. The sequela of an untreated or undertreated GAS pharyngitis include Rheumatic Fever (RF) and Rheumatic Heart Disease (RHD). Despite evidence for the effectiveness of antibiotics such as …

Comparative and Functional Genomic Analysis of <i>Streptococcus Equi</i> and <i>Streptococcus Zooepidemicus</i> : Identifying Novel Vaccine Targets
Streptococcus equi subspecies equi (<i>S. equi</i>) is a host-restricted pathogen of horses and the aetiological agent of strangles. Available evidence suggests that <i>S. equi</i> evolved from <i>Streptococcus equi</i> subspecies <i>zooepidemicus</i> (<i>S. zooepidemicus</i>), a versatile …

Potential Approaches to Limiting Group A Streptococcus Virulence
Group A Streptococcus (GAS) is an obligate human pathogen capable of causing a wide array of diseases ranging in both severity and site of infection. The current forms of treatment are limited, consisting of antibiotic regimens and in severe cases surgical debridement to remove infected tissue. …

Survival Strategies of Streptococcus mutans during Carbohydrate Starvation
Streptococcus mutans is a facultative member of the oral plaque and is associated with dental caries. It is able to survive long periods of sugar starvation. The purpose of this project was to explore specific avenues that S. mutans may use in order to cope with carbohydrate deprivation. …

Streptococcus equi subsp. zooepidemicus in New Zealand horses
Streptococcus equi subsp. zooepidemicus (S. zooepidemicus) is an opportunistic commensal bacterium of the horse mucosa causing disease in susceptible populations. This research sets out to enhance the understanding of S. zooepidemicus infections within the New Zealand horse population through …

Functional Characterization of the Streptococcus sanguinis com Regulon
Streptococcus sanguinis is an important component of the dental plaque biofilm and is believed to play a beneficial role in the oral cavity. S. sanguinis is also a leading cause of infective endocarditis (IE), a potentially lethal infection of the cardiac valves. S. sanguinis possesses genetic …
