  • Publication number: 20180051313
    Abstract: Methods of detecting microorganisms in a fluid sample are provided. The method includes providing a nonwoven article, providing a fluid sample suspected of containing at least one microorganism strain or target cellular analyte, and contacting the fluid sample with the nonwoven article such that at least a portion of the at least one microorganism strain or target cellular analyte is bound to the nonwoven article. The nonwoven article includes a fibrous porous matrix and a concentration agent particles enmeshed in the fibrous porous matrix. The method further includes placing the microorganism strain- or target cellular analyte-bound nonwoven article in contact with at least one detection reagent and detecting the presence of the bound microorganism strain or bound target cellular analyte. Devices and kits containing the devices, for contacting a fluid sample with a nonwoven article, are also provided.
