Improved cards for use in an automated machine to detect the presence of specific microbes and thereby identify them, enumerate them, and/or determine their susceptibility to antibiotics. Each card includes a plate having conical detection wells each with a selected medium therein, at least one filling port with a septum which is retained by a collar formed therein, and filler passages of specific length and configuration connecting the port to the wells. Discontinuities are provided in the filler passages to prevent unwanted fluid flow and to reduce migration of the microbes when the card is in use. Overflow chambers of a specific configuration are also provided adjacent the wells to entrap bubbles.
