Clumping factor A of Staphylococcus aureus interacts with AnnexinA2 on mammary epithelial cells
Staphylococcus aureus is one of major pathogens that can cause a series of diseases in different hosts. In the bovine, it mainly causes subclinical and contagious mastitis, but its mechanisms of infection are not fully understood. Considering the fact that virulence factors play key roles in interactions between the bacterium and host cells, this study aimed to identify if a binding partner of ...
متن کاملProtection against experimental Staphylococcus aureus arthritis by vaccination with clumping factor A, a novel virulence determinant.
The importance of the fibrinogen-binding adhesin clumping factor A (ClfA) in the pathogenesis of Staphylococcus aureus septic arthritis was examined in an animal model. The protective effect of active and passive immunization with ClfA also was investigated in S. aureus infection models. The severity of arthritis was markedly reduced in mice challenged intravenously with a clfA mutant, compared...
متن کاملAcid phosphatase activity in Coxiella burnetii: a possible virulence factor.
High-speed supernatant fluids derived from sonicated Coxiella burnetii contained considerable acid phosphatase activity when assayed by using 4-methylumbelliferylphosphate; they also contained a factor that blocked superoxide anion production by human neutrophils stimulated with formyl-Met-Leu-Phe. The pH optimum of the enzyme was approximately 5.0. The level of phosphatase activity detected in...
متن کاملInlP, a New Virulence Factor with Strong Placental Tropism.
Intrauterine infection is a major detriment for maternal-child health and occurs despite local mechanisms that protect the maternal-fetal interface from a wide variety of pathogens. The bacterial pathogen Listeria monocytogenes causes spontaneous abortion, stillbirth, and preterm labor in humans and serves as a model for placental pathogenesis. Given the unique immunological environment of the ...
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 ...
