1. A device for collecting a sample, the device comprising:
- a) a body comprising a sample collection chamber bounded on a distal end by a penetrable seal affixed to a recessed sealing surface of the distal end of the body and bounded on a proximal end by a septum comprising an aperture, said penetrable seal being penetrable by a pipette tip or needle;
b) a flexible sampling rod comprising a proximal portion and a distal portion, said sampling rod adapted to fit through and seal said aperture when said distal portion is in said sample collection chamber, wherein said distal portion comprises;
i) an asymmetrical beveled tip at a distal end, said beveled tip having an apex at the circumference of the flexible sampling rod and configured to bend the flexible sampling rod away from collisions and/or to deflect collisions with an inserted pipette tip or needle; and
ii) a plurality of stacked coaxial frusta of cones to form a plurality of metering ridges;
andc) a fecal sample suspension solution in said sample collection chamber, said fecal sample suspension solution comprising Tris buffer, bovine serum albumen, polysorbate 20, sodium azide, sodium chloride, ethylenediaminetetraacetic acid, and gentamicin.

33. A system for collecting a sample, the system comprising:
-
a) a sample collection chamber for holding a fecal sample suspension solution comprising Tris buffer, bovine serum albumen, polysorbate 20, sodium azide, sodium chloride, EDTA ethylenediaminetetraacetic acid, and gentamicin; b) a penetrable seal for sealing said chamber at a recessed sealing surface on an end and configured to allow access to said chamber by penetrating said penetrable seal with a pipette tip or needle; c) a flexible sampling rod for contacting a sample and acquiring a portion of said sample, said flexible sampling rod comprising an asymmetrical beveled tip comprising an apex at the circumference of the flexible sampling rod and configured to bend the flexible sampling rod away from and/or to deflect collisions with an inserted pipette tip or needle; and d) a plurality of stacked coaxial frusta of cones to form a plurality of metering ridges for providing into said chamber a defined volume of said acquired portion of the sample.
