Downstream Effects of Haemoglobinase Inhibition in Plasmodium falciparum-Infected Erythrocytes
(2010)Blood-stage malarial parasites (Plasmodium falciparum) digest large quantities of host haemoglobin during their asexual development in erythrocytes. The haemoglobin digestion pathway, involving a succession of cleavages ... -
Pathogenomic analysis of the common bovine Staphylococcus aureus clone (ET3): emergence of a virulent subtype with potential risk to public health
(University of Chicago Press, 2008)A common clone (ET3) of Staphylococcus aureus is responsible for a large proportion of cases of bovine mastitis and occasionally causes zoonotic infections of humans. In the present study, we report the identification of ... -
The transcriptional programme of Salmonella enterica serovar Typhimurium reveals a key role for tryptophan metabolism in biofilms.
(BioMed Central, 2009)Background Biofilm formation enhances the capacity of pathogenic Salmonella bacteria to survive stresses that are commonly encountered within food processing and during host infection. The persistence of Salmonella within ... -
Network analysis of the transcriptional pattern of young and old cells of Escherichia coli during lag phase.
(BioMed Central, 2009)Background The aging process of bacteria in stationary phase is halted if cells are subcultured and enter lag phase and it is then followed by cellular division. Network science has been applied to analyse the transcriptional ... -
BABAR: an R package to simplify the normalisation of common reference design microarray-based transcriptomic datasets.
(BioMed Central, 2010)BACKGROUND: The development of DNA microarrays has facilitated the generation of hundreds of thousands of transcriptomic datasets. The use of a common reference microarray design allows existing transcriptomic data to be ... -
Beta-neurexin is a ligand for the Staphylococcus aureus MSCRAMM SdrC
(2010)Gram-positive bacteria contain a family of surface proteins that are covalently anchored to the cell wall of the organism. These cell-wall anchored (CWA) proteins appear to play key roles in the interactions between ... -
Key role for clumping factor B in Staphylococcus aureus nasal colonization of humans.
(2008)Staphylococcus aureus permanently colonizes the vestibulum nasi of one-fifth of the human population, which is a risk factor for autoinfection. The precise mechanisms whereby S. aureus colonizes the nose are still unknown. ... -
Sequence diversity in the A domain of Staphylococcus aureus fibronectin-binding protein A.
(2008)Background: Fibronectin-binding protein A (FnBPA) mediates adhesion of Staphylococcus aureus to fibronectin, fibrinogen and elastin. We previously reported that S. aureus strain P1 encodes an FnBPA protein where the ... -
Fibrinogen binding sites P336 and Y338 of clumping factor A are crucial for Staphylococcus aureus virulence.
(2008)We have earlier shown that clumping factor A (ClfA), a fibrinogen binding surface protein of Staphylococcus aureus, is an important virulence factor in septic arthritis. When two amino acids in the ClfA molecule, P336 and ... -
A potential new pathway for Staphylococcus aureus dissemination: silent survival of S.aureus phagocytosed by human monocyte-derived macrophages.
(2008)Although considered to be an extracellular pathogen, Staphylococcus aureus is able to invade a variety of mammalian, non-professional phagocytes and can also survive engulfment by professional phagocytes such as neutrophils ... -
The Staphylococcus aureus "superbug"
(2004)There has been some debate about the disease-invoking potential of Staphylococcus aureus strains and whether invasive disease is associated with particularly virulent genotypes, or "superbugs." A study in this issue of the ... -
Molecular characterization of the interaction of staphylococcal microbial surface components recognizing adhesive matrix molecules (MSCRAMMS) ClfA and Fbl with fibrinogen
(2010)The ligand binding domain of the fibrinogen binding protein from Staphylococcus lugdunensis (Fbl) shares 60% sequence identity with clumping factor A (ClfA) of Staphylococcus aureus. Recombinant Fbl corresponding to the ... -
Plasmodium berghei ANKA: selection of resistance to piperaquine and lumefantrine in a mouse model.
(Elsevier, 2009)We have selected piperaquine (PQ) and lumefantrine (LM) resistant Plasmodium berghei ANKA parasite lines in mice by drug pressure. Effective doses that reduce parasitaemia by 90% (ED90) of PQ and LM against the parent line ... -
A common theme in interaction of bacterial immunoglobulin-binding proteins with immunoglobulins illustrated in the equine system
(The American Society for Biochemistry and Molecular Biology, 2008)The M protein of Streptococcus equi subsp. equi known as fibrinogen-binding protein (FgBP) is a cell wall-associated protein with antiphagocytic activity that binds IgG. Recombinant versions of the seven equine IgG subclasses ... -
Anti-malarial effects of macrolactones related to FK520 (ascomycin) are independent of the immunosuppressive properties of the compounds
(University of Chicago Press, 2005)The polyketide macrolactone FK506 inhibits the growth of Plasmodium falciparum in culture and the enzymatic (peptidyl-prolyl cis-trans isomerase [PPIase]) and chaperone activities of a recently identified P. falciparum ... -
PEST sequences in the malaria parasite Plasmodium falciparum: a genomic study
(BioMed Central, 2003)Anopheles gambiae is the main vector of Plasmodium falciparum in Africa. The mosquito midgut constitutes a barrier that the parasite must cross if it is to develop and be transmitted. Despite the central role of the mosquito ... -
P53 CODON 72 POLYMORPHISM AND HUMAN PAPILLOMAVIRUS ASSOCIATED SKIN CANCER
(2001)BACKGROUND/AIMS-NON-MELANOMA SKIN CANCERS FREQUENTLY HARBOUR MULTIPLE HUMAN PAPILLOMAVIRUS (HPV) TYPES. A RECENT REPORT SUGGESTS THAT ALPOLYMORPHISM OF THE P53 TUMOUR SUPPRESSOR GENE THAT RESULTS IN THE SUBSTITUTION OF A ...
