Card for use in an automated microbial detection system
First Claim
1. In card for use in detecting the presence of microbes in a specimen wherein the card is comprised of a plate having first and second sides, detection wells for containing microbe supportive media passing from a first side to a second side therethrough, at least one filling port with a septum therein, filler passageways formed in said first side of the plate connecting said filling port to said detection wells and adhesive tape on both sides of the plate to cover said detection wells and filler passageways, the improvement comprising:
- at least one discontinuity in one of said filler passageways adjacent a detection well.

Abstract
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.
