Abstract

Group E streptococci are identified by a group antigen consisting of a cell wall rhamnose-glucose polymer. Other specific cell wall polysaccharides separate the group into at least six serotypes (II, IV, V, VI, VII and VIII). No species name has been accepted for the group E Streptococcus, although the organism is often designated as Streptococcus infrequens or S. lentus. Recently, the name S. porcinus has been proposed for a species that would include streptococci of groups E, P, U and V.

Group E streptococci are fairly widely distributed in animals, especially swine, and are occasionally isolated from bovine milk. They cause streptococcal lymphadenitis of swine, an economically important disease, particularly in the United States. They do not appear to be the primary cause of any other disease or condition.

The organisms enter the swine host through the mucosa of the pharyngeal or tonsillar surfaces, and are carried to the lymph nodes, primarily of the head and neck region, where abscesses are formed. Cell wall antigens induce the formation of serum agglutinins; a microtitration agglutination test, based upon reactions involving the type IV antigen, is considered a reliable test for detection of infection in animals.

Antigenic components include group and type antigens, extra-cellular enzymes, and an antiphagocytic factor which may be associated with virulence of the organism and with protective immunity to streptococcal lymphadenitis of swine. This factor, a surface resistant to phagocytosis by porcine leukocytes.

The classification, morphology, physiology, biochemistry and nutrition of the group E streptococci, and methods for their isolation, cultivation, and identification are reviewed.

Species identification of Streptococcus porcinus by restriction fragment length polymorphism analysis of 16S ribosomal DNA
1998, Research in Veterinary Science
Streptococcus porcinus reference strains and routine isolates belonging to Lancefield's serogroup E, P, U and V and to various serotypes of serogroup E were examined for their 16S ribosomal DNA fingerprint pattern. Oligonucleotide primers complementary to 16S rRNA genes were used to amplify gene fragments by polymerase chain reaction from genomic DNA. The amplified 1450 bp fragment was subsequently digested with the restriction enzyme BpiI resulting in two fragments with a size of approximately 1250 by and 200 bp. All 45 S porcinus investigated in the present study could be identified on the basis of this characteristic 16S rDNA fingerprint pattern and clearly differentiated from 16 control strains of various species and serogroups of genus Streptococcus. The present results demonstrate the potential application of 16S rDNA analysis for identification of S porcinus, a species which might express various group- and type-specific antigens.
Cross-reactivity between human sialyl Lewis<sup>x</sup> oligosaccharide and common causative oral bacteria of infective endocarditis
1995, FEMS Immunology and Medical Microbiology
The expression of sialyl-Lewis^x (sLe^x; Neu5Ac α2–3 Galβ1–4 (Fuc α1–3) GlcNAc-R) on oral bacteria producing infective endocarditis was determined by a whole-cell enzyme linked immunosorbent assay and an immunoelectron microscopy using the well-characterized anti-sLe^x monoclonal antibody SNH-3 (mAb SNH-3; IgM class). mAb SNH-3 reacted strongly with whole cells of oral bacteria: Streptococcus sanguis, Streptococcus mutans, Streptococcus mitis, Streptococcus salivarius, Streptococcus intermedius, Streptococcus constellatus, Streptococcus anginosus, Streptococcus pyogenes, Actinobacillus actinomycetemcomitans, Eikenella corrodens and Porphyromonas gingivalis. The negatively stained immuno-electron micrograph of Streptococcus pyogenes showed many reactive gold particles on the cell surface. Our findings demonstrated the existence of immunologic mimicry between the sLe^x oligosaccharide and cell surface antigens of many species associated with infective endocarditis. We propose the hypothesis that if these bacteria escape their normal habitats, the surface components that mimic the sLe^x oligosaccharide might bind to host antigens of the selectin family which could promote binding to endothelial cells and, consequently, initiation of the events leading to infective endocarditis.
Bacterial immunogens and protective immunity in swine
1994, Veterinary Immunology and Immunopathology
This review provides a limited discussion of antibody-mediated immune responses to bacterial pathogens which cause disease in swine. Serum antibody titers or responses have been used to correlate immunization or convalescence with protection from a given disease or infectious agent. Though much effort has been devoted to the elucidation of the host's antibody response to bacterial antigens, there are limited examples where an antibody response to a singular antigen has induced protection from disease. Antibody responses have been shown to be very effective in neutralizing bacterial exotoxins, e.g. Escherichia, Pasteurella, Actinobacillus, and inhibiting the ability of bacterial pathogens to colonize mucosal surfaces, e.g. Escherichia, Salmonella. The protective role of monospecific antibody responses to other bacterial components are less clear; however, antibody responses are generally polyclonal in nature and are an important component of the host immune response following the onset of disease. Anticapsular antibodies have been shown to enhance phagocytosis of numerous pathogens, e.g. Actinobacillus, Streptococcus, Pasteurella. Humoral immune responses directed against the lipopolysaccharide (LPS) of many Gram-negative organisms have been shown to enhance phagocytosis and the activation of complement, e.g. Salmonella. Anti-LPS antibodies have also aided in the identification of the serotypic diversity of Gram-negative organisms, e.g. Serpulina, Salmonella, Pasteurella. Antibody responses to the outer membrane proteins of Gram-negative organisms enhance phagocytosis, activation of complement, or inhibit bacterial adhesion to host cell. Adhesion of Gram-positive microorganisms, e.g. Staphylococcus, Streptococcus, Clostridium, to eukaryotic cells can be inhibited by antibody against the peptidoglycan and these peptidoglycan-specific antibodies may also facilitate opsonization of these organisms. Mycoplasma species have been shown to be metabolically inhibited by antibody directed against membrane proteins. In addition to the protective aspects of humoral immunity, the host's antibody response has been used as a diagnostic and epidemiological tool to identify or determine the prevelance of infectious agents.
Identification of α-galactosyl and other carbohydrate epitopes that are bound by human anti-pig antibodies: relevance to discordant xenografting in man
1993, Transplant Immunology
Human anti-pig antibodies were obtained by perfusing pig hearts (n = 4) and kidneys (n = 8) with human AB or O plasma followed by elution with 3 M NaSCN. The antibodies were screened against a panel of 132 synthetic carbohydrates conjugated to bovine serum albumin using an enzyme-linked immunoassay. An anti-immunoglobulin antibody was also used to detect immunoglobulin deposits on pig tissues. Four carbohydrate molecules with a terminal α-galactose residue bound all but one of the human anti-pig kidney antibodies and most of the anti-pig heart antibodies. These were: (i) αGal(1→3)βGal(1→4)βGlcNac (linear B type 2); (ii)αGal(1→3)βGal(1→4)βGlc (linear B type 6); (iii) αGal(1→3)βGal(B disaccharide); and (iv) αGal(α-D-galactose). Immunoglobulin deposition was documented post-plasma perfusion in all pig hearts and particularly strongly in all pig kidneys. These results suggest that human anti-pig antibodies are mainly directed against α-galactosyl structures. Extracorporeal immunoadsorption of human plasma through columns of the specific synthetic carbohydrate(s) might lead to depletion of anti-pig antibodies and allow discordant xenografting in man. Alternatively, the infusion of the specific carbohydrate(s) for a period of several days might result in neutralization of the anti-pig antibodies and allow accommodation to take place.
