This review of the immunological diagnosis of parasitic diseases defines the various indications, the means of collection and preparation, the various levels of specificity and the choice of parasitic antigen which should be used for immuno-diagnosis. The detection and assay of circulating antibodies relies on the techniques of immuno-precipitation (immunodiffusion, immunoelectrophoresis, electrosyneresis), indirect agglutination (latex and haemagglutination) or the use of labelled compounds (immunofluorescence, enzymo-immunoassay, radio-immunoassay). Their respective advantages and disadvantages are discussed. The detection and assay of circulating antigens involve the use of agglutination techniques (mycoses), radio-immunoassay or enzymo-immunoassay (protozooses and helminthiases). The authors review the applications of immunological diagnosis for the helminthiases (Trichinosis, Toxocarosis, Filariasis, Anguillosis, Ascaridiasis, Echinococcosis, Taeniasis and Cysticercosis, Distomatosis and Schistosomiasis), the protozoan infections (malaria, Toxoplasmosis, Amebiasis, Trypanosomiasis, Leishmaniasis) and the mycoses (Aspergillosis, Candidiasis, Cryptococcosis). They also discuss the prospects for the development of immunological diagnosis by identification, purification and standardization of parasitic antigens and the study of circulating antigens and idiotypic anti-parasitic antibodies. Finally, they outline the respective responsibilities of the biologist and the prescribing doctor for the proper use of immunological diagnosis of parasitic diseases.

An evaluation of health problems is done in a village in Eastern Madagascar, where takes place a development programme. 217 inhabitants go through physical examination and lab tests are performed (Blood smear - Thick drop. Emmel test. Stools examination for parasites and enteroviruses). The epidemiologic investigation reveals the prevalences of Malaria (39,4 p. 100) intestinal schistosomiasis (59,9 p. 100) Ascaridiasis (61,3 p. 100) Hookworm (29,9 p. 100) Trichuriasis (19,8 p. 100) and sickle cells anemia (4,80 p. 100). The signs and symptoms are analysed, particularly spleen enlargement which is shown to be due to schistosomiasis. The local transmition pattern of schistosomiasis is investigated and, according to the malacological findings, is thought to be intermittent. The determination of the local hookworm is started. It should be Necator americanus. The sanitary programme to be set is considered regarding the local contexte.

The structure of a parasite system is formed and its functioning takes place in qualitatively different environments. The aquatic environment serves as a source of new elements and modules, energy, and information for parasite systems. And the parasite systems, for their part, affect the physical and biological parameters of the environment. Many intestinal infections caused by pathogenic microorganisms generally characterized by an acute disease course are related to a water factor. Such are typhus, typhoids, dysentery, cholera, salmonellosis, virus hepatitis, and others. Many parasitic diseases caused by pathogenic intestinal protistae (lambliasis, amebiasis, balantidiasis), blood parasite protistae (malaria), helminthes (opisthorchiasis, fascioliasis, diphyllobothriasis, cercariosis, pseudoamphistomosis) are also closely related to a water factor. Ascaridiasis, hymenolepiasis, trichocephalosis, and echinococcosis have a less close but still self-evident relationship to a water factor. The clbse relationships of many parasitic diseases to a water factor are also determined by the fact that the life cycles of many parasites necessarily include various intermediate hosts and parasite vectors, such as fishes, mollusks, crustaceans, and insects, which are aquatic organisms at some stages of their life. The results of continuous exposure of people to parasitic diseases are quite similar to the suppressive effects of the environment in the ecologically troublesome regions. The most prognostically useful information is formed while mapping by medical and ecological regions, by employing a combination of current mathematical and cartographical methods. The former include cluster analysis, quartering method, informational logical analysis, which are all described in this article and others. Regional mapping using the parasitological criteria should achieve at least two goals: 1) a scientific one that aids in finding causative connections and to prognosticate a situation; 2) a practical one that assists in developing regional programs for disease control and prevention. It is necessary to use the recommendations described in detail in the article in order to have the maximum results during medical and ecological mapping by the regions with a future goal of obtaining useful prognostic information.
