Incubation at 37#{176}Cfor 30 mm or the addition of CaCl2 (5 mM) generated platelet-clumping activity in citrated plasma and EDTA plasma previously acidified to pH 5.5 and in which heparin was added to give a concentration of 0.5 mg/mi. Similar treatment could not produce platelet-clumping activity in saline or denatured plasma that had been heated to 56#{176}C.Heparin, chondroitin sulfate B, o...

The Staphylococcus aureus MSCRAMM (microbial surface components recognizing adhesive matrix molecules) protein clumping factor A (ClfA) has been shown to be a critical virulence factor in several experimental models of infection. This report describes the generation, characterization, and in vivo evaluation of a murine monoclonal antibody (MAb) against ClfA. Flow cytometric analysis revealed th...

Platelet clumping is a common laboratory phenomenon that complicates or precludes reporting of platelet count. It is often, but not always, a phenomenon commonly caused by the anticoagulant EDTA. Herein, we discuss a case of a 14-year-old girl who was found to have platelet clumping and discuss the work-up she underwent to investigate her pseudothrombocytopenia.

Hot massive stars exhibit strong stellar winds that enrich the surrounding interstellar medium and affect stars' evolution. However, are inhomogeneous (clumped) difficult to model in radiative transfer codes. To produce more realistic spectra many codes use a volume-filling factor approach incorporate effects of clumping. While this is convenient it simplistic. We introduce an alternative clump...

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 based...

Staphylococcus aureus has become increasingly resistant to antibiotics, and vaccines offer a potential solution to this epidemic of antimicrobial resistance. Targeting of specific T cell subsets is now considered crucial for next-generation anti-S. aureus vaccines; however, there is a paucity of information regarding T cell antigens of S. aureus This study highlights the importance of cell wall...
