Cuvette for detecting bacteria

摘要

A method for detecting and counting particles suspended in fluids, such as bacteria suspended in urine, utilizing dynamic features of the suspended particles and employing light scattering measurements. The disclosed method is suitable for determining the susceptibility of bacteria to antibiotics. A cuvette for detecting bacteria in fluids, which is especially suited for the light scattering measurements, is provided.

主权项

1. A cuvette for use in detecting bacteria in a fluid sample, comprising:
a first compartment having first and second windows and for holding the fluid sample, the windows being transparent and having a surface roughness in which the root mean square (RMS) value does not exceed one nanometer, the first compartment for receiving a beam of light that enters the first window along an axis, the beam of light for causing scattered light indicative of the bacteria within the fluid sample to exit the second window at locations spaced apart from the axis; a second compartment adjacent to said first compartment; and a divider including a porous structure that is located between the first compartment and the second compartment.
