OBJECTIVE To measure antibody titres to cardiac, nuclear, and streptococcal antigens in different groups of rheumatic fever (n = 60) and control subjects (n = 80) with the aim of identifying cross reactive antigens of potential laboratory diagnostic value. METHODS Enzyme linked immunosorbent assays (ELISA), immunocytochemical, and electrophoretic techniques were used to measure titres of anti...
A number of commensal oral streptococcal species produce a heterogeneous group of proteins that mediate binding of salivary α-amylase. This interaction likely influences streptococcal colonization of the oral cavity. Here, we present draft genome sequences of several strains of oral streptococcal species that bind human salivary amylase.
Invasive group A streptococcal infection is a severe disease with high mortality. Invasive group A streptococcal infection may arise after pelvic inflammatory disease. Pelvic inflammatory disease in postmenopausal women is rare. Here, we report a unique case of a postmenopausal woman with fatal invasive group A streptococcal infection due to pelvic inflammatory disease and an extraordinary cour...
Proteins of Streptococcus mutans MT703 were isolated by differential filtration from chemically defined culture medium following growth of the bacteria. Incubation of this preparation with cryostat-cut sections of fresh rabbit cardiac muscle resulted in deposition of streptococcal components on basement membranes of sarcolemmal sheaths and capillary walls, as indicated by indirect immunofluores...
BACKGROUND Acute pharyngitis in children is one of the most frequent illnesses for which primary care physicians are consulted. It is caused more frequently by viruses than by bacteria, but it is difficult to differentiate the causative agent by clinical signs alone. Group A Streptococcus accounts for 30% of children with a sore throat, and only in these cases is antibiotic therapy definitely i...
BACKGROUND The classical neurological disorder after group A beta haemolytic streptococcal infection is Sydenham's chorea. Recently a tic disorder occurring after group A streptococcal infection has been described and termed PANDAS (paediatric autoimmune neuropsychiatric disorders associated with streptococcal infection). It is proposed that antibodies induced after group A streptococcal infect...
Group B streptococcal disease remains a prominent cause of infectious morbidity in pregnant women and their infants. This article highlights recent developments that are relevant for obstetricians, perinatologists, and neonatologists caring for patients with group B streptococcal disease. The morbidity of group B streptococcal infections in pregnancy and the proposed association of colonization...
Acute streptococcal gingivitis is an acute inflammation of the oral mucosa and also seen with the other oral diseases as aggressive periodontitis that is characterized by a considerable attachment loss over a short period of time. Streptococcal infections of gingiva are seen rarely; also the origin of this gingival inflammation is occasionally different from that of routine plaque-associated gi...
The purpose of this study was to isolate streptococcal strains from the oral cavities of streptococcal endocarditis patients and compare these strains biochemically and genetically with the corresponding streptococcal blood isolates. Total identity was observed between the blood and oral cavity isolates from the two patients studied.
The clinical association of streptococcal infections and psoriasis is well established. The recent finding that the T cells in psoriasis skin respond to streptococcal peptidoglycan now suggests a pathway for an adaptive immune response to the streptococcal organism. These observations may allow for possible vaccines to be developed for psoriasis.
