Schaudinn sentence example
- Schaudinn  and Delage and Herouard (Hydrozoa ).
- Schaudinn (1900), have been most in favour.
- Schaudinn had fully described the relations of certain avian Trypanosomes to their invertebrate host, Culex pipiens (females).
- In view, however, of the great interest excited by Schaudinn's work on avian parasites, as well as on account of the far-reaching importance of his conclusions to the study of the Haematozoa, a brief summary of his celebrated research is necessary.
- According to Schaudinn's account, he was dealing with two separate Trypanosome parasites of the Little Owl (Athene noctua), viz.Advertisement
- So far as regards the remarkable connexion between Trypanosomes and Haemosporidia indicated by Schaudinn, this has met with a great deal of criticism on the part of Novy and McNeal among others, and it must be admitted that up to 1909 no definite corroboration can be said to have been brought forward.
- In short, it is quite possible Schaudinn did not sufficiently distinguish between the life-cycles of four distinct parasites of the Little Owl: a Trypanosome, a Spirochaete, a Halteridium and a Leucocytozoon; though, on the other hand, this is by no means proved.
- Brumpt (5a), Leger (32, 33), Keysselitz (16), Prowazek (47), Minchin (41b) and others - has undoubtedly shown that much of Schaudinn's scheme of the life-history of a Trypanosome is well-founded.
- Different investigators, it may be noted, have described various (After Schaudinn.) FIG.
- Of the discoveries of new organisms the most important is that of the Spirochaete pallida in syphilis by Schaudinn and Hoffmann in 1905; and although proof that it is the cause of the disease is not absolute, the facts that have been established constitute very strong presumptive evidence in favour of this being the case.Advertisement
- Schaudinn (50), who investigated certain avian Trypanosomes, considered the latter view to be correct, and believed that the carrier - in this instance a gnat - is indeed the definitive host, i.e.
- Schaudinn has stated, however, that Trypanomorpha becomes, in certain phases, attached to a red blood-corpuscle (ectoglobular), and, in others, penetrates inside one and eventually destroys it (endoglobular); while his other avian parasite, Trypanosoma ziemanni, apparently draws up into itself the white corpuscle (leucocyte) to which it becomes attached.
- In the blood of the owl resting, intracellular phases of both parasites alternate with active trypaniform ones; and, when in the former condition, Schaudinn considers that the parasites are identical with what have been formerly regarded as distinct Haemosporidia, Halteridium and a Leucocytozoon respectively.
