Disclosed is a method for detection and/or quantification of microorganism in a liquid sample, in particular in a water sample, the method comprising the steps of: (a) distributing the liquid sample into a number of different discrete volume portions in a linear distribution pattern, or diluting the liquid sample into a number of dilution samples by a dilution factor of a linear distribution pattern; (b) allowing the microorganism to grow; and (c) applying the Most Probable Number method to the linearly distributed volume portions or the linearly diluted dilution samples to detect and/or quantify the microorganism. The invention also discloses a sample holder for detection and/or quantification of microorganism in a liquid sample, wherein the sample holder is structured to hold the liquid sample in a number of different compartments, wherein the different compartments respectively define a linear volume distribution.

A system and method for rapid detection of viable microorganisms (e.g., pathogens) in liquid media suspensions utilizes at least two electrodes in electrical communication with a suspension (e.g., liquid media possibly containing microorganisms). Electrical response to an electrical pulse in a short initial time window (e.g., no longer than a time required to attain 95% (or another threshold percentage) of a steady state electrical response value after a change in state of the pulse) permits bulk electrical response of the suspension between the electrodes to be determined before electrical response signals are dominated by double layer formation at surfaces of the electrodes. Pulse application and detection of electrical response to a change in state of a pulse may be repeated over time, with changes in such response being useful to detect microorganism proliferation in a bulk suspension.

Described herein are methods, systems, and non-transitory computer-readable media to non-destructively acquire three-dimensional profiles of cellular microbiological samples growing on the surface of a solid growth medium. Acquisitions can be performed by an optical microscope that includes a vertical scanning interferometer. The three-dimensional profiles can enable measurement of sample parameters of microcolonies, which can be made of microbial colony forming units. The methods and systems enable early and rapid detection and quantification of microbes.
