From page 178...
... Malaria decimated the troops of ancient Rome, and microscopic blood parasites determined the results of more battles than did the most famous leaders. Fleas which transmitted a causative agent of the plague Pasteurella pestis caused the extinction of one-third of the European population in the 17th century.

... Also, some negative factors influence the life cycles of parasites so they have no possibility to realize their developmental stages in the given environment. For example, trichinellosis in pigs and man can be eliminated in large-scale breeding of pigs, since pigs have no contacts with freeliving animals and the reservoirs of trichinelles in the human food chain are consequently reduced.

... The introduction of biotechnological methods in production of monoclonal antibodies would be of great significance, and these antibodies could become a source of immunosorbents for obtaining highly specified antigens. After the Second World War insecticides based on chlorohydrocarbons, especially DDT and HCH, were extensively used to destroy insect pests affecting plant production and parasites detrimental to health.

... Much knowledge has been obtained about the geographical distribution and ecological conditions during the development of various parasitic species, including the introduction of some parasites in Czechoslovakia. Recently in the spotlight are questions of the influence of anthropogenic factors on the development of parasites, including the introduction of parasites, warming of water, new technologies in breeding of domestic animals, and landscape changes.

... Gastrointestinal nematodes parasitizing in domestic animals are considered to be the main cause of important economic losses. In recent years, problems of protozoan diseases of young farm animals, especially calves, piglets, and lambs have stimulated research on cryptosporidial infections.
