Complement and antibody participation in opsonophagocytosis of type IV and V group B streptococci.
Requirements for complement and antibody in neutrophil-mediated killing of serotype IV and V group B streptococci were investigated. Neutrophils from adults were tested in an opsonophagocytic assay with sera from healthy adults, healthy newborns, and hypogammaglobulinemic, agammaglobulinemic, and C4-deficient patients. For all serum sources, the bactericidal index for both serotypes exceeded 84...

این مطالعه در سال 1386-87 در آزمایشگاه و مزرعه پژوهشی دانشگاه صنعتی اصفهان به منظور تعیین مناسب ترین تیمار بذری و ارزیابی اثر پرایمینگ بر روی سه رقم گلرنگ تحت سه رژیم آبیاری انجام گرفت. برخی از مطالعات اثرات سودمند پرایمینگ بذر را بر روی گیاهان مختلف بررسی کرده اند اما در حال حاضر اطلاعات کمی در مورد خصوصیات مربوط به جوانه زنی، مراحل نموی، عملکرد و خصوصیات کمی و کیفی بذور تیمار شده ژنوتیپ های م...
Capsular sialic acid limits C5a production on type III group B streptococci.
The majority of type III group B streptococcus (GBS) human neonatal infections are caused by a genetically related subgroup called III-3. We have proposed that a bacterial enzyme, C5a-ase, contributes to the pathogenesis of neonatal infections with GBS by rapidly inactivating C5a, a potent pro-inflammatory molecule, but many III-3 strains do not express C5a-ase. The amount of C5a produced in se...
