Characteristics of virulent, attenuated, and avirulent Mycoplasma pneumoniae strains.
Homologous pairs of virulent and attenuated or avirulent Mycoplasma pneumoniae strains were derived and compared in an effort to elucidate the mechanisms of virulence. These related strains were found to vary in growth, glycolysis, protein electrophoretic patterns, peroxide formation, morphology, and cytadsorption. Variations in the last two characteristics closely correlated with avirulence. T...
متن کاملSurface proteins of Bordetella pertussis: comparison of virulent and avirulent strains and effects of phenotypic modulation.
The surface proteins of several Bordetella strains and their modulated derivatives were examined by surface radioiodination, cell fractionation, and Western blotting. A surface protein with a high Mr, missing in a mutant lacking the filamentous hemagglutinin, was identified in virulent Bordetella pertussis and Bordetella parapertussis cells and was absent in avirulent B. pertussis strains. The ...
متن کاملAcute induction of cell death-related IFN stimulated genes (ISG) differentiates highly from moderately virulent CSFV strains
Classical swine fever (CSF) severity is dependent on the virulence of the CSF virus (CSFV) strain. The earliest event detected following CSFV infection is a decrease in lymphocytes number. With some CSFV strains this leads to lymphopenia, the severity varying according to strain virulence. This lymphocyte depletion is attributed to an induction of apoptosis in non-infected bystander cells. We c...
متن کاملGenomic comparison of virulent Rickettsia rickettsii Sheila Smith and avirulent Rickettsia rickettsii Iowa.
Rickettsia rickettsii is an obligate intracellular pathogen that is the causative agent of Rocky Mountain spotted fever. To identify genes involved in the virulence of R. rickettsii, the genome of an avirulent strain, R. rickettsii Iowa, was sequenced and compared to the genome of the virulent strain R. rickettsii Sheila Smith. R. rickettsii Iowa is avirulent in a guinea pig model of infection ...
متن کاملIdentification of Secreted Exoproteome Fingerprints of Highly-Virulent and Non-Virulent Staphylococcus aureus Strains
Staphylococcus aureus is a commensal inhabitant of skin and mucous membranes in nose vestibule but also an important opportunistic pathogen of humans and livestock. The extracellular proteome as a whole constitutes its major virulence determinant; however, the involvement of particular proteins is still relatively poorly understood. In this study, we compared the extracellular proteomes of poul...
