A Handbook of Health Its place in the scheme of existence is not wholly certain, but the probability seems that it is a protozoan, belonging to the lowest form of animal life. An Ethical Problem Or, Sidelights upon Scientific Experimentation on Man and Animals And the complexity of the aggregation, the federation of the parts constantly increases with the ascent in the zoological series from protozoa to Man. Socialism and Modern Science (Darwin, Spencer, Marx) The great majority of marine protozoa have been described from European waters, and the descriptions are usually not elastic enough to embrace the forms found at Woods Hole. Marine Protozoa from Woods Hole Bulletin of the United States Fish Commission 21:415-468, 1901 The possibility of its being a protozoan is suggested by the above-named investigators through their observations of round or rod-shaped bodies in the round cells of the secretions. Special Report on Diseases of the Horse The various examples we have mentioned and the groups to which they belong clearly occupy different places in the scale which begins with the protozoa and extends upward to the most complicated and differentiated animals. The Doctrine of Evolution Its Basis and Its Scope The ovum itself can become the site of infection; this, which was first discovered by Pasteur in the eggs of silkworms, takes place not infrequently in the infection of insects with protozoa. Disease and Its Causes All unicellular beings, such as the protozoa and the simpler alg�, fungi, etc., reproduce themselves by means of simple fission. Scientific American Supplement, No. 810, July 11, 1891 Food consists of foreign objects, diatoms, other protozoa and the like. Marine Protozoa from Woods Hole Bulletin of the United States Fish Commission 21:415-468, 1901 Negri claims that these bodies are not only specific for rabies, but that they are protozoa and the cause of the disease. Special Report on Diseases of the Horse Some species of the bell-animalcule, Vorticella, provide characteristic examples of these primitive compound protozoa. The Doctrine of Evolution Its Basis and Its Scope There are few bacterial diseases which are localized in the blood, but many of the diseases caused by protozoa have this localization. Disease and Its Causes By the development of this process, multicellular metazoa arose from the colonies of similar protozoa, and at length culminated in the higher animals and man. Scientific American Supplement, No. 810, July 11, 1891 I could not make this out, for although other protozoa ran against this bristle, often bending it well over to one side, the animal showed no sign of irritability but lay quiescent. Marine Protozoa from Woods Hole Bulletin of the United States Fish Commission 21:415-468, 1901 Valenti states, as his strongest evidence of the protozoan nature of the bodies, that the virus of rabies is neutralized in test tubes by quinin, while no other alkaloid has this property. Special Report on Diseases of the Horse These elements are not all alike, as in the case of colonial protozoa like Vorticella, for they fall into two classes which are distinguished by certain structural and functional characteristics. The Doctrine of Evolution Its Basis and Its Scope The protozoa are the most widely distributed and the most universal of the parasites. Disease and Its Causes The protozoa developed the cell for all time to come, the cœlenterata developed the tissues which still compose our bodies. The Whence and the Whither of Man A Brief History of His Origin and Development through Conformity to Environment; Being the Morse Lectures of 1895 The fusion of the nuclei of the two cells was regarded by Van Beneden, who in 1875 first accurately described it, as a process of conjugation comparable to that of the protozoa and the protophyta. Studies in the Psychology of Sex, Volume 5 Erotic Symbolism; The Mechanism of Detumescence; The Psychic State in Pregnancy But in the case of the bacteria and protozoa, we can have a new generation every hour or so, sometimes every half hour. Q. E. D., or New Light on the Doctrine of Creation Hydra takes its place above the protozoa for obvious structural reasons; worms belong to a still higher zone, surpassed by the more complex jointed animals like crustacea and insects. The Doctrine of Evolution Its Basis and Its Scope It is not known whether these organisms belong to the bacteria or protozoa, and naturally nothing is known as to their form, size and structure. Disease and Its Causes The protozoa are mostly, though not purely, nutritive and reproductive. The Whence and the Whither of Man A Brief History of His Origin and Development through Conformity to Environment; Being the Morse Lectures of 1895 We don't want to hear about the "behavior" of protozoans while our best song birds are being exterminated by negroes and poor whites. Our Vanishing Wild Life Its Extermination and Preservation Among the unicellular plants are the bacteria, while the unicellular animals are known as the protozoa. Q. E. D., or New Light on the Doctrine of Creation We would hardly expect to find remains of ancient microscopic animals like the protozoa, unless they possessed shells or other skeletal structures which in their aggregate might form masses like the chalk beds of Europe. The Doctrine of Evolution Its Basis and Its Scope The protozoa, like the bacteria, are unicellular organisms and contain a nucleus as do all cells. Disease and Its Causes The protozoa include also the flagellata, a great, very poorly defined mass of forms occupying the boundary between the plant and animal kingdoms.

Scott's Last Expedition Volume I The pond in which bacteria and protozoa are living may dry up, and these organisms may be killed by the billion. The Doctrine of Evolution Its Basis and Its Scope A fluid environment is essential to the life of the protozoa, but the resistant forms can endure long periods of dryness or other unfavorable environmental conditions. Disease and Its Causes And these cells, forming a series through all generations, are evidently immortal like the protozoa. The Whence and the Whither of Man A Brief History of His Origin and Development through Conformity to Environment; Being the Morse Lectures of 1895 A textbook of bacteriology, with a section on pathogenic protozoa; the application of bacteriology and immunology. U.S. Copyright Renewals, 1964 July - December At that point of being the development of the protozoa is arrested. Famous Reviews The relations of protozoa and bacteria, conger-eels and other fish, English sparrows and hawks, plants and herbivorous animals, are typical examples of the universal conflict in which all organisms are involved in some way. The Doctrine of Evolution Its Basis and Its Scope Most of the diseases in animals caused by bacteria and protozoa are not transmitted to man, but there is a conspicuous exception. Disease and Its Causes Naturally in the early protozoan colonies, and in forms like hydra, these functions predominated. The Whence and the Whither of Man A Brief History of His Origin and Development through Conformity to Environment; Being the Morse Lectures of 1895 A textbook of bacteriology, with a section on pathogenic protozoa. U.S. Copyright Renewals, 1964 July - December Bivalve and univalve mollusca seem to be rare at the greatest depths; but starfishes, sea urchins and other echinoderms, zoophytes, sponges, and protozoa abound. Discourses Biological and Geological Essays Does this mean that man and all the other higher forms have evolved from protozoa in the course of long ages? The Doctrine of Evolution Its Basis and Its Scope The food of protozoa consists chiefly of other organisms, particularly bacteria, and they are classed with the animals. Disease and Its Causes In studying protozoa we noticed that they reproduced by fission, each adult individual dividing into two young ones. The Whence and the Whither of Man A Brief History of His Origin and Development through Conformity to Environment; Being the Morse Lectures of 1895 The only exception is found in the protozoa, the very lowest and simplest forms of animal life; these remain unicellular throughout life. The Evolution of Man — Volume 1 Sincerity or honesty is a low and very rudimentary form of virtue that is only to be found to any considerable extent among the protozoa. The Note-Books of Samuel Butler I do not think we could ask nature for more complete proof that human beings have evolved from one-cell ancestors as simple as modern protozoa beyond the obvious facts of human transformation during development. The Doctrine of Evolution Its Basis and Its Scope Variation does not seem to be so marked in the protozoa as in the bacteria, though this is possibly due to our greater ignorance of them as a class. Disease and Its Causes The protozoa are immortal, not in the sense of the endless persistence of the individual, but of the absence of death. The Whence and the Whither of Man A Brief History of His Origin and Development through Conformity to Environment; Being the Morse Lectures of 1895 But all the other animals—all the tissue-forming animals, or metazoa, as we call them, in contradistinction to the protozoa—construct real germinal layers by the repeated cleavage of the impregnated ovum. The Evolution of Man — Volume 1 Among these were diatoms, algae, protozoa, rotifera, and bacteria. The Home of the Blizzard Being the Story of the Australasian Antarctic Expedition, 1911-1914 "Give us time," says Life, starting with her protozoans in the old Cambrian seas, "and I will not stop till I have peopled the earth with myriad forms and crowned them all with man." Time and Change The universal distribution of the protozoa is due to this; the spores or cysts can be carried long distances by the wind and develop into active forms when they reach an environment which is favorable. Disease and Its Causes These somatic cells, being mortal, differ altogether from the germ-cells and the protozoa. The Whence and the Whither of Man A Brief History of His Origin and Development through Conformity to Environment; Being the Morse Lectures of 1895 All these animals may be comprised under the general heading of "gut animals," or metazoa, in contradistinction to the gutless protozoa. The Evolution of Man — Volume 1 Rich earth abounds with single cell organisms like bacteria, actinomycetes, fungi, protozoa, and rotifers. Organic Gardener's Composting Can we doubt that each series is the outcome of the one below it—that there is a logical sequence from the protozoa up through the invertebrates, the vertebrates, to man? Time and Change The living organisms which cause the infectious diseases are classified under bacteria, protozoa, yeasts, moulds, and ultra-microscopic organisms. Disease and Its Causes To explain this Weismann went back to the unicellular protozoa. The Whence and the Whither of Man A Brief History of His Origin and Development through Conformity to Environment; Being the Morse Lectures of 1895 The earliest one-celled protozoa were probably succeeded by many- celled animals of the type of the blastosphere, and these by gastrula-like organisms. The Elements of Geology It is probable that segmentation could be carried much further in some of the protozoa; and with some of the lowest plants each cell will reproduce the parent-form. The Variation of Animals and Plants under Domestication — Volume 2 The original and germinal idea would naturally divide itself into another, as the protozoa reproduce themselves. Adventures Among Books Of almost equal value have been the researches upon the protozoan forms of animal life, as causes of disease. The Evolution of Modern Medicine A Series of Lectures Delivered at Yale University on the Silliman Foundation in April, 1913 He now accepts the view that external influences may act upon the germ-plasm not only in protozoa but also in all higher animals. The Whence and the Whither of Man A Brief History of His Origin and Development through Conformity to Environment; Being the Morse Lectures of 1895 The fertilized egg-cell, formed by the union of egg and spermatozoon, is a single cell, like the individual resulting from the conjugation or fusion of two protozoa. The Whence and the Whither of Man A Brief History of His Origin and Development through Conformity to Environment; Being the Morse Lectures of 1895 And there is a just as real continuity of germ-plasm through successive generations of volvox, or of any higher plants or animals, as in successive generations of protozoa. The Whence and the Whither of Man A Brief History of His Origin and Development through Conformity to Environment; Being the Morse Lectures of 1895 The result of these widespread observations was the confirmation in every respect of Laveran's discovery of the association with malaria of a protozoan parasite.
