Genome-Wide CRISPR-Cas9 Screen Does Not Identify Host Factors Modulating Streptococcus agalactiae β-Hemolysin/Cytolysin-Induced Cell Death

open access: yesMicrobiology Spectrum, 2022
Pore-forming toxins (PFTs) are commonly produced by pathogenic bacteria, and understanding them is key to the development of virulence-targeted therapies. Streptococcus agalactiae, or group B Streptococcus (GBS), produces several factors that enhance its

Genetic islands of Streptococcus agalactiae strains NEM316 and 2603VR and their presence in other Group B Streptococcal strains [PDF]

open access: yes, 2005
BACKGROUND: Streptococcus agalactiae (Group B Streptococcus; GBS) is a major contributor to obstetric and neonatal bacterial sepsis. Serotype III strains cause the majority of late-onset sepsis and meningitis in babies, and thus appear to have an ...

Genomic evidence for the evolution of Streptococcus equi : host restriction, increased virulence, and genetic exchange with human pathogens [PDF]

open access: yes, 2009
The continued evolution of bacterial pathogens has major implications for both human and animal disease, but the exchange of genetic material between host-restricted pathogens is rarely considered. Streptococcus equi subspecies equi (S.

Evidence for niche adaptation in the genome of the bovine pathogen Streptococcus uberis [PDF]

open access: yes, 2009
Background Streptococcus uberis, a Gram positive bacterial pathogen responsible for a significant proportion of bovine mastitis in commercial dairy herds, colonises multiple body sites of the cow including the gut, genital tract and mammary gland ...

Phylogenomic analysis of natural selection pressure in Streptococcus genomes [PDF]

open access: yes, 2007
In comparative analyses of bacterial pathogens, it has been common practice to discriminate between two types of genes: (i) those shared by pathogens and their non-pathogenic relatives (core genes), and (ii) those found exclusively in pathogens (pathogen-

Maternal and Neonatal Colonisation of Group B Streptococcus at Muhimbili National Hospital in Dar es Salaam, Tanzania: Prevalence, Risk Factors and Antimicrobial Resistance. [PDF]

open access: yes, 2009
Group B streptococcus (GBS), which asymptomatically colonises the vaginal and rectal areas of women, is the leading cause of septicemia, meningitis and pneumonia in neonates. In Tanzania no studies have been done on GBS colonisation of pregnant women and

Invasive group B streptococcal infection in infants, Malawi. [PDF]

open access: yes, 2007
Group B streptococci (GBS) are a recently identified cause of neonatal sepsis in Malawi. In Queen Elizabeth Central Hospital, Blantyre, Malawi, during May 2004-June 2005, GBS were isolated from routine blood and cerebrospinal fluid cultures from 57 ...

Role of macrophage sialoadhesin in host defense against the sialylated pathogen group B Streptococcus [PDF]

open access: yes, 2014
Several bacterial pathogens decorate their surfaces with sialic acid (Sia) residues within cell wall components or capsular exopolysaccharides. Sialic acid expression can promote bacterial virulence by blocking complement activation or by engagement of ...
