“…Bindings of IgG, fibrinogen, fibronectin, a,-macroglobulin, and albumin to group L streptococci occurred in similar patterns as those of the respective proteins t o streptococci of serological groups C and G (Chhatwal et al 1985). Bindings of 1251-labelled human IgG to group L streptococci could be inhibited by unlabelled IgG preparations f r o m humans a n d bovines b u t not by chicken IgG.…”

Of 33 streptococcal cultures belonging to serological group L, all bound human immunoglobulin (Ig) G, fibrinogen, and fibronectin; 32 bound bovine IgG; 31 bound alpha 2-macroglobulin; 5 bound albumin; and none bound either haptoglobin or IgA. The binding sites for IgG could be isolated from the L streptococci by trypsinization and purified by affinity chromatography on human IgG-Sepharose. The purified Fc receptors reacted with IgG subclasses 1, 2, 3, 4 of humans, 1 and 2 of bovines, ovines, and caprines as well as a, b, c, and T of equines. They had a molecular mass of approximately 49,000 Da. Thus, the Fc receptors from L streptococci corresponded to type III Fc receptors of Streptococcus dysgalactiae.

“…After a 1-h incubation at room temperature, the bacteria were washed and the radioactivity in the sediment was measured. The uptake of radiolabelled protein wag expressed as the percentage of the total activity remaining in the bacterial pellet (Chhatwal et al 1985).…”

“…The first reports on S. pyogenes attachment to fibronectin and collagen appeared during the 1980s and supported the concept of an initial specific binding to the ECM (Switalski et al, 1982;Myhre and Kuusela, 1983;Chhatwal et al, 1985Chhatwal et al, , 1990. For most of the GAS isolates described in these studies the clinical background was unclear and correlations between the binding characteristics and the GAS-induced diseases were not found.…”

“…These binding proteins have been reported on staphylococci (Forsgren & Sjoquist, 1966), streptococci of serological groups A, B, C, G, L and U (Kronvall, 1973;Chhatwal et al, 1985), and other microorganisms such as Haemophilus somnus, Clostridium perfringens and Mycoplasma salivarium (Lindahl & Kronvall, 1988;Yarnall et al, 1988;Sawa et al, 1992).…”

This study was undertaken to search for the presence of immunoglobulin G (1gG)-binding proteins in Streptococcus suis, an important swine pathogen. Whole bacterial cells were incubated with human or pig IgG conjugated to gold particles and examined by transmission electron microscopy. Cells of some S. suis strains were labelled as were cells of the positive control strain, Staphylococcus aureus Cowan I. Binding of pig and human IgG to five different bacterial species of group D streptococci, to reference strains representing the 29 capsular types of S. suis, and to 12 S. suis capsular type 2 strains was then examined using Western blotting. All strains interacted with pig and human IgG, although the binding profiles were slightly different. A 52 kDa protein was observed in all capsular types of S. suis. This protein, absent in other group D streptococcal species, was observed in all capsular type 2 isolates originating from diseased or clinically healthy pigs, and was shown to bind human IgG-Fc fragments. The IgG-binding activity was also observed in the culture supernatant and was sensitive to proteolysis.
