Comparison of albumin receptors expressed on bovine and human group G streptococci.
The albumin receptor expressed by bovine group G streptococci was extracted and affinity purified. The protein was characterized for species reactivity, and monospecific antibodies were prepared to the purified receptor. The bovine group G albumin receptor was compared functionally, antigenically, and for DNA homology with the albumin-binding protein expressed by human group G streptococci. In ...
متن کاملDifferentiation of species in human beta-haemolytic group G streptococci using immunoglobulin Fc fragment receptor.
AIMS To assess the ability of human immunoglobulin Fc fragment binding activity to differentiate human biotype large colony group G streptococci from the group G "Streptococcus milleri group". METHODS Fifty two isolates of large colony group G streptococci and 30 group G "S milleri group" strains were tested for their ability to bind fluorescein conjugated human IgG Fc fragments after acetone...
متن کاملBacteremia Caused by Group G Streptococci, Taiwan
A retrospective observational study in Taiwan, 1998-2004, identified 92 patients with group G streptococcal bacteremia; 86 had Streptococcus dysgalactiae subspecies equisimilis. The most common diagnosis was cellulitis (48 cases), followed by primary bacteremia (34 cases). Infection recurred in 9 patients. Mortality rate was low (3.3%); resistance to quinupristin-dalfopristin was high.
متن کاملImmunochemical Studies on the Specific Carbohydrate of Group G Streptococci
Group G hemolytic streptococcal cell walls which have been treated with trypsin are composed of a group-specific polysaccharide moiety and a mucopeptide matrix. The mucopeptide contains N-acetylglucosamine, N-acetylmuramic acid, alanine, glutamic acid, lysine, and glycine, a composition similar to that of other groups of streptococci. The Group G carbohydrate is composed of rhamnose, N-acetylga...
متن کاملSpecific absorption of human serum albumin, immunoglobulin A, and immunoglobulin G with selected strains of group A and G streptococci.
Five gram-positive bacterial strains were selected for absorption studies of human serum samples. Strain AR1 (group A, M-type 1) and G148 (group G), with strong immunoglobulin G (IgG) binding capacities, and strain AW43 (group A, M-type 60), binding both IgA1 and IgA2, were compared with Staphylococcus aureus Cowan I and with Staphylococcus epidermidis L603. Both AR1 and G148 were capable of co...
