Comminution of feces and preparation for analysis

1. An analytical toilet comprising:

a bowl for collecting feces from a user;

a comminutor that comminutes at least a portion of the feces;

a processing fluid driver that causes a processing fluid to mix with and transport at least a portion of the comminuted feces to an analytical station in the toilet;

a separator that separates a sample of the at least a portion of the comminuted feces to be analyzed; and

a wash fluid driver that causes a wash fluid to wash the feces out of the bowl.

2. The analytical toilet of claim 1 , wherein the processing fluid driver comprises a fluid jet, nozzle, microfluidic, capillary, diaphragm, piston, screw, rotary, or peristaltic dispensing system.

3. The analytical toilet of claim 1 , further comprising a cover that separates the comminutor from the bowl.

4. The analytical toilet of claim 1 , further comprising a filter between the comminutor and the analytical station.

5. The analytical toilet of claim 4 , wherein the filter comprises a disk filter.

6. The analytical toilet of claim 4 , wherein the sample is moved to the analytical station through a microfluidic channel.

7. The analytical toilet of claim 1 , wherein the comminutor is selected from the group consisting of an auger, an emulsifier, a masticator, a sonicator, a homogenizer, high pressure fluid, a mill, blender, Dounce homogenizer, Potter-Elvehjem homogenizer, French press, and a grinder.

8. The analytical toilet of claim 1 , wherein the processing fluid comprises water together with at least one of a buffer, a reducing agent, a protease inhibitor, an osmolyte, an ionic stabilizer, and an α-helix stabilizer.

9. The analytical toilet of claim 1 , wherein the separator comprises a pipette.

10. The analytical toilet of claim 1 , further comprising an imaging sensor for capturing images of the comminuted feces.

11. The analytical toilet of claim 10 , further comprising a channel through which a portion of the comminuted feces passes, thereby producing a thin layer of comminuted feces, and wherein the imaging sensor is on one side of the thin layer of comminuted feces and a light source is on the other side of the thin layer of comminuted feces.

12. The analytical toilet of claim 10 , further comprises a processor that processes images captured by the imaging sensor to thereby recognize parasites, parasite larva, parasite eggs, bacteria or viruses.

13. The analytical toilet of claim 12 , wherein the processor is capable of recognizing images of one or more of cryptosporidium, microsporidia, and isospora, tapeworms, flukes, Fasciolopsis buski, hookworms, microsporidia, whipworms, protozoa, Balantidium coli, Dientamoeba fragilis, Encephalitozoon hellem, Necator americanus, heterophyes heterophyes, Metagonimus yokogawai, pinworms, trichinosis worms, Giardia intestinalis, Giardia lamblia, Entamoeba histolytica, Cyclospora cayetanenensis, ascarias lumbricoides, strongyloidiasis, Ancylostoma duodenale, Taenia, Cystoisospora belli, Diphyllobothrium, Hymenolepsis, Echinococcus, Dipylidium, Spirometra, Enterobius vermicularis, and Cryptosporidium.

14. The analytical toilet of claim 1 , wherein the analytical station comprises a slide warmer.

15. The analytical toilet of claim 1 , wherein the analytical station comprises a dispenser that dispenses a stain, a fixative, a reagent, or combinations thereof.

16. The analytical toilet of claim 15 , wherein the one or more stains comprise eosin/saline, acridine orange, auramine phenol, Field's stain solution A and B, Giemsa stain, Lugol's iodine, iron haematoxylin solution A and B, trichrome for microsporidia, trichrome for protozoa, malachite green, methylene blue, Gram's fuchsin, safranin O, Gram's iodine, crystal violet, or Kinyoun's Carbol fuchsin.

17. An analytical toilet for collecting, analyzing, and disposing of feces comprising:

a bowl for collecting feces from a user;

a source of acoustic energy directed at the feces and having sufficient intensity to comminute the feces to an extent sufficient to produce comminuted feces; and

a source of flush water to wash the comminuted feces out of the bowl.

18. The analytical toilet of claim 17 , further comprising an imaging sensor for capturing images of the comminuted feces.

19. The analytical toilet of claim 18 , further comprising a channel through which a portion of the comminuted feces passes, thereby producing a thin layer of comminuted feces, and wherein the imaging sensor is on one side of the thin layer of comminuted feces and a light source is on the other side of the thin layer of comminuted feces.

20. The analytical toilet of claim 17 , further comprising a processor for processing images from the imaging sensor, and thereby recognize images of one or more parasites.
