Streptococcus agalactiae (Group B streptococcus, GBS) is a leading cause of infections in neonates and an emerging pathogen in adults. The Lancefield Group B carbohydrate (GBC) is a peptidoglycan-anchored antigen that defines this species as a Group B Streptococcus. Despite earlier immunological and biochemical characterizations, the function of this abundant glycopolymer has never been address...

The immunological phenomena associated with various aspects of hemolytic streptococcus disease in man have usually been studied by the measurement of antitoxins. Most extensive have been the observations made by the Dick technique (1), in which purified erythrogenic toxin was used as a skin test material. Circulating antistreptolysin and antifibrinolysin titers have also been determined, partic...

OBJECTIVES To investigate antibiotic sensitivities of Streptococcus pneumoniae, viridans streptococci, and group A hemolytic streptococci isolated from the culture materials obtained from the sinuses of patients undergoing functional endoscopic sinus surgery due to chronic sinusitis. PATIENTS AND METHODS We recruited 93 patients (63 males, 30 females; mean age 36+/-17.5; range 19 to 68 years)...

Although there is common agreement and occasionfal mention of the fact that nephritis once healed does not recur, there has been little evidence presented in the literature to substantiate this impression. Longcope (1) reports 4 cases out of a series of 24 with healed acute nephritis in whom beta hemolytic streptococci were found subsequently. Two of these, in a single throat culture each, reve...

preterm premature rupture of membrane(PPROM)is one of the serious problems during pregnancy.the aim of this study was to determine the probable relation between group B streptococal and anaerobic infections and PPROM.for this porpust 100 pregnant women with preterm rupture of membrane were selected.in the case group the prevalence of B-hemolytic streptococcal and anaerobic microorganisms was de...

Streptococcus agalactiae (group B Streptococcus, GBS) vaginal pathogenicity is not uniformly acknowledged throughout the literature; accordingly, in women, genital itching and burning, along with leukorrhea are commonly and almost exclusively referred to bacterial vaginosis, candidiasis and trichomoniasis. Conversely, GBS virulence for vagina was recognized in the past, as the organism has been...

Troisier and Monaldi (Rg. Med., 1932, 96), having changed Lowenstein's method, performed blood cultures of patients who had one or another infectious disease. A.a. describe 3 cases, from the which VC were cultivated: 1st patient with endocarditis (blood culture produced non-hemolytic streptococcus) died septic cerebral infarction, autopsy did not reveal a single tbc focus. Nth. Croupous pneumon...

A culture of hemolytic streptococcus developed a non-hemolytic fraction which as determined by its agglutinogenic, agglutination, and agglutinin absorotion characters was identical with the hemolytic fraction, the only variation being one of function, or physiological action. This functional variation has proved permanent, as long as observed, for both fractions have continued to breed true. Th...
