Topics such as "parasitic animals, a menace to human health" are contents of the biological and health instruction in senior high schools and junior colleges offering general education. There is no doubt that in the near future this curricular aspect will be paid more and more attention to. This transparency atlas hence shall inspire, but also offer the substantial and necessary help to realise an instruction characterized by a higher degree of clearness due to its illustrative material. Almost 50% of all human diseases in the developing countries are caused by parasites, and those animals which constitute human food are affected in a still higher degree. Our modern times are characterized by mass tourism, and travels of teenagers to subtropical and tropical countries of the Third World are no longer the rare exceptions. As developed countries show a rising tendency of diseases caused by parasites - also by earlier in these regions almost unknown ones - more action is called for in the sphere of schools, too. That is why this transparency atlas, due to its excellent usefulness to instruction, applies not only to students of human and veterinary medicine, but also to school biologists. To all of them this atlas offers reliable help with its brilliant microphotographs, typical pictures of diseases, impressive life cycles and the text, based on the latest scientific findings.
