Immunogenicity 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 کاملFibrinogen-binding protein/clumping factor from Staphylococcus aureus.
The binding of staphylococcal components to fibrinogen was studied. Fibrinogen-binding material from lysed staphylococcal cells or culture supernatants was affinity purified on fibrinogen-Sepharose and analyzed on Western (immuno-) blots by the use of fibrinogen and antifibrinogen antibodies. Two main bands of 87 and 19 kilodaltons (kDa) and a weaker band of 35 kDa bound specifically to fibrino...
متن کاملStaphylococcus 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 کاملClumping of Staphylococcus aureus in the peritoneal cavity of mice.
Kapral, Frank A. (Philadelphia General Hospital, Philadelphia, Pa.). Clumping of Staphylococcus aureus in the peritoneal cavity of mice. J. Bacteriol. 92:1188-1195. 1966.-Nonencapsulated strains of Staphylococcus aureus inoculated into the peritoneal cavity of mice are promptly clumped by the interaction of fibrinogen with the bound coagulase present on the bacterial surface. Some of the pre-ex...
متن کاملKey Role for Clumping Factor B in Staphylococcus aureus Nasal Colonization of Humans
BACKGROUND 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. The staphylococcal cell-wall protein clumping factor B (ClfB) promotes adhesion to squamous epithelial cells in vitro and might be a physiologically relevant colon...
