Abstract
The present disclosure provides materials and methods for separating organisms from various other components of a composition. In particular, the present disclosure provides devices, systems, and methods for separating and washing helminths from contaminants such as bacteria.
Claims19
A method of separating microorganisms, the method comprising:
- a) applying a composition comprising a plurality of microorganisms and one or more contaminants to a device comprising:
- a column having a first end for receiving the composition and a second end distal to the first end,
- a fluid inlet port proximal to the second end of the column for receiving washing fluid, and
- a waste outlet port proximal to the first end of the column;
- b) applying a washing fluid to the device via the fluid inlet port;
- and
- c) actively transporting the washing fluid and contaminants contained therein to the waste outlet port using a pump as the plurality of microorganisms passes from the first end to the second end of the column counter to the flow of the washing fluid, thereby separating the plurality of microorganisms from contaminants in the composition.
