The free availability of only about 10–20 mol/l iron in human body fluids thus presents a challenge to them arthritis in dogs not eating order feldene 20mg on-line. At this stage of development treating arthritis early order generic feldene on line, the immune system is un- able to recognize bacterial immunogens as foreign arthritis in neck lump in throat purchase feldene canada. Molecular mimicry refers to the presence of molecules on the surface of bacteria that are not recognized as foreign by the im- mune system. Examples of this strategy are the hyaluronic acid capsule of Streptococcus pyogenes or the neuraminic acid capsule of Escherichia coli K1 and serotype B Neisseria meningitidis. Mucosal immunity to gonococci depends on antibodies in the secretions of the urogenital mucosa that attach to the immunodominant seg- ment of the pilin, thus blocking adhesion of gonococci to the target cells. The gonococcal genome has many other pil genes besides the pilE without promoters, i. Intracellular homologous recombination of conserved regions of silent pil genes and corre- sponding sequences of the expressed gene results in pilE genes with changed cas- settes. Some bacteria are characterized by a pronounced variability of their immunogens (= immune antigens) due to the genetic variability of the structural genes coding the antigen proteins. This results in production of a series of antigen variants in the course of an infection that no longer “match” with the antibodies to the “old” antigen. Examples: gonococci can modify the primary structure of the pilin of their attachment Kayser, Medical Microbiology © 2005 Thieme All rights reserved. The borreliae that cause relapsing fevers have the capacity to change the structure of one of the adhesion proteins in their outer 1 membrane (vmp = variable major protein), resulting in the typical “recur- rences” of fever. Similarly, meningococci can change the chemistry of their capsule polysaccharides (“capsule switching”). Mucosal secretions contain the secretory antibodies of the sIgA1 class responsible for the specific local immunity of the mucosa. Classic mucosal parasites such as gonococci, meningococci and Haemophilus influ- enzae produce proteases that destroy this immunoglobulin. Clinical Disease The clinical symptoms of a bacterial infection arise from the effects of dama- ging noxae produced by the bacteria as well as from excessive host immune responses, both nonspecific and specific. Immune reactions can thus poten- tially damage the host’s health as well as protect it (see Immunology, p. Obligate intracellular parasites (rickettsiae, chlamy- diae) may kill the invaded host cells when they reproduce. Pathogenic bacteria can produce a variety of toxins that are either the only pathogenic factor (e. One aspect the clas- sification and nomenclature of these toxins must reflect is the type of cell affected: cytotoxins produce toxic effects in many different host cells; neu- rotoxins affect the neurons; enterotoxins affect enterocytes. The structures and mechanisms of action of the toxins are also considered in their classifica- tion (Table 1. They consist of a binding subunit “B” responsible for binding to specific surface receptors on target host cells, and a catalytic subunit “A” representing the active agent. These toxins disrupt biological membranes, either by attaching to them and assembling to form pores, or in the form of phos- pholipases that destroy membrane structure enzymatically. These antigens stimulate T lymphocytes and macrophages to produce excessive amounts of harmful cytokines.

They must then be secreted through the cytoplasmic membrane, and in Gram-negative bacteria through the outer membrane as well.

Alternatively, other antigens can be fixed to the erythrocyte surface and the agglutination monitored (above right). The so-called “prozone” phenomenon results from non-specific blocking mechanisms present in sera which has not been sufficiently diluted. For this purpose tissue sections, or cell preparations, are treated with specific antibodies (anti-sera) which have been labeled with a fluorochrome (Fig. Usage subject to terms and conditions of license Immunological Test Methods 127 Antigen Detection Methods 2 Fig. The term indirect immunofluorescence is used when it is not the primary antibody being detected, but a secondary antibody which is directed against the unlabeled primary antibodyand has also been labeled with a fluorochrome or enzyme (b). However, an even higher level of amplification can be achieved using preformed complexes of secondary antibody and enzyme (c). For the peroxidase method the detector enzyme is bounddirectly tothe secondary antibody (peroxidase catalyzes a color reaction). In the biotin-avidin method the detector enzymes are coupled to either biotin or avidin. The antigen–antibody com- plexes that form are then detected using a labeled or “second” antibody, di- rected against the first antibody (Fig. Instead of fluorochromes, enzy- me-labeled antibodies are now frequently used for tissue sections. The en- zyme catalyzes the formation of a color signal following addition of a pre- viously colorless detector substance. This color precipitate allows the direct observation of signals using a light microscopic, and exhibits little bleaching. Indirect immunofluorescence can be used for the qualitative and quanti- tative analysis of antibodies directed against particular microbial antigens, or self-tissue antigens, within a patients serum. In the quantitative test, the anti- gen is fixed in a well or to a tissue section on a slide. The patient sample is repeatedly diluted by a factor of two and added to the antigen or section then rendered visible with a labeled anti–antibody. There are two main methods of amplifying the immunohistological color signal: Kayser, Medical Microbiology © 2005 Thieme All rights reserved.
