1888, Scientific Memoirs by Officers of the Medical and Sanitary Departments of the Government of India XI, page 47:
Thus, first, under similar experimental conditions this minute hæmatophyte does not, contrary to the pathogenetic bacterium, display any tendency to grow in the blood after withdrawal from the body: it does not then, however, comport itself like the ordinary putrefactive microphytes, but, as already stated, after quiescence so long as watched seems gradually to decay.
In the abstract there seems no valid reason why hæmatozoa living as hæmatophytes should not be attended with analogous or even identical symptoms of derangement in hosts of the same species; but hitherto such an assertion as this, if doubted, could not be suitably tested, and hence the cognomen of “equine relapsing fever” (employed by Mr. Steel) must now be interpreted as in a special degree significant. To the best of my recollection, none of the hæmatophytes are harmless tenants of the blood, all being possessed of pathogenetic properties and all, moreover, belonging to the fungus- (or alga-) group of schizomycetes: whereas no such uniformity of property, or of classification, obtains amongst the known hæmatozoa, and hence of these an important differentiation may and has now to be made.
[… -]genically communicable; immunity, congenital, acquired, and artificial, and the effects of inoculation, injection, and transfusion; the entity and life-history of the organism of malaria, a disease communicable miasmatically to man but not from man, and that forms a connecting link between diseases caused by hæmatozoa and those caused by hæmatophytes; the differentiation of the life-histories of biotic and toxic microphytes, revealing the difference between diseases caused by hæmatophytes and entophytes.
