Crossword-Solution: PIROPLASMA 10 letters, 1 clue 🏆 scrabble score: 16

The virus which is present in the blood may be transmitted to a number of equines in a series of inoculations by injecting either the whole blood, the defibrinated blood, or the blood serum which has been passed through a fine Pasteur filter, thus eliminating all the visible forms of organismal life, including bacteria, trypanosoma, piroplasma, etc.

These animal microbes are often spoken of as "blood-flagellates" or hæmo-flagellata, and the larger kinds are called "Trypanosomes," or "screw-form parasites," or whilst a series of more minute ones are called "Piroplasma," or "pear-shaped parasites." Many, but not all, are found during a certain period of their life, actually inside the corpuscles of the blood.

These parasites have usually been given the generic name _Piroplasma_ and hence the type of disease which they cause is often referred to as "_piroplasmosis_." The best known illustration is the disease known in this country as Texas fever of cattle.

Again, the inclusion or exclusion of forms like _Piroplasma_ and _Halteridium_ is also the subject of much discussion.

Allied to this latter type of form are the trophozoites of _Piroplasma_, which are normally pear-shaped; they differ, however, in being very minute, and, moreover, exhibit considerable polymorphism, rod-like (so-called bacillary) and ring-forms being of common occurrence.
