Staphylococcus aureus Clumping Factor A Remains a Viable Vaccine Target for Prevention of S. aureus Infection
In a recent article, X. Li et al. [mBio 7(1):e02232-15, 2016, http://dx.doi.org/10.1128/mBio.02232-15] investigate the utility of a vaccine composed of the Staphylococcus aureus protein clumping factor A (ClfA) in protecting mice from S. aureus infection. ClfA, one of the first proteins to be identified as a potential vaccine antigen for S. aureus prophylaxis, is currently a component of severa...
متن کاملGenetic evidence that bound coagulase of Staphylococcus aureus is not clumping factor.
Staphylococcus aureus Newman cells carry a surface receptor for fibrinogen called clumping factor. The bacteria also express coagulase, an extracellular protein that binds to prothrombin to form a complex with thrombinlike activity which coverts fibrinogen to fibrin. We have confirmed a recent report (M. K. Bodén and J.-I. Flock, Infect. Immun. 57:2358-2363, 1989) that coagulase can bind to fib...
متن کاملImmunogenicity analysis of Staphylococcus aureus clumping factor A genetic variants.
The staphylococcal adhesin clumping factor A (ClfA) has a variant amino acid sequence, generating the potential for alterations in epitope structure and immunogenicity of this vaccine candidate. We demonstrated for two recombinant ClfA(40-531) (a slightly truncated version of the fibrinogen-binding domain of ClfA containing amino acids 40 to 531) genetic variants that strain-specific epitopes a...
متن کاملConstruction of a New Fusion Protein Vector Associated to Fibronectin Binding Protein A and Clumping Factor A Derived from Staphylococcus aureus NCTC8325
Objective(s) Staphylococcus aureus is a leading cause of many nosocomial and community acquired infections. According to many reports, antibiotic therapy can not guarantee the eradication of S. aureus infections. Thus designing an adhesin based vaccine could restrain the S. aureus infections. This study designed for construction of a new fusion protein vaccine against S. aureus infections base...
متن کاملFibrinogen Binding Sites P336 and Y338 of Clumping Factor A Are Crucial for Staphylococcus aureus Virulence
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, P(336) and Y(338), were changed to serine and alanine, respectively, the fibrinogen binding property was lost. ClfAP(336)Y(338) mutants have been constructed in two virulent S. aureus ...
