Biochemical Studies on the Fibrinolytic Activity of Hemolytic Streptococci I. Isolation and Characterization of Fibrinolysin
The fibrinolytic activity of hemolytic streptococci designates the capacity of cultures of the organisms to liquefy rapidly human fibrin clot (1). The lyric action is referable to the presence in the culture of an extracellular substance, characteristically elaborated by those strains of hemolytic streptococci which are derived from patients suffering with acute streptococcus infections. Invest...
متن کاملEvidence for In Utero Hematogenous Transmission of Group B β-hemolytic Streptococcus
BACKGROUND The presumed ascending route of group B beta-hemolytic streptococcus (GBS) infection from the colonized maternal genital tract is well accepted. This case report proposes a hematogenous, selective infection of one unruptured amniotic sac over the other ruptured amniotic sac in a twin gestation in a patient with known GBS vaginal colonization. CASE This is a case report of GBS sepsi...
متن کاملStudies on the Listerella Group: I. Biochemical and Hemolytic Reactions.
Although the organisms now known as Listerella were first reported as a new species by Murray, Webb and Schwann (1926), and were given the genus name by Pirie (1927), earlier reports contain descriptions which indicate that the organisms were seen prior to 1926. Atkinson (1917) noted a gram-positive diphtheroid organism in five human cases of what was thought to be epidemic cerebrospinal mening...
متن کاملIsolation and characterization of Faecalibacterium prausnitzii extracellular vesicles
Introduction: Extracellular vesicles (EVs) contain active biological compounds which play important roles in biological processes. The secretion of EVs is a common phenomenon which occurs in archaea, bacteria and mammalian cells. The secretion of bacterial EVs has been discovered in various species of both Gram-negative and Gram-positive bacteria. Faecalibacterium prausnitzii is one of the comm...
متن کاملMolecular characterization of nontypeable group B streptococcus.
Traditionally, the capsular polysaccharide (CPS) antigen has been used to distinguish between the nine known serotypes of group B streptococcus (GBS) by classical antibody-antigen reactions. In this study, we used PCR for all CPSs and selected protein antigens, multilocus sequencing typing (MLST), and pulsed-field gel electrophoresis (PFGE) to molecularly characterize 92 clinical isolates ident...
