Abstract

Provided herein are fully-automated next-generation sequencing platforms and processes for detection of a target specimen (e.g., SARS-CoV-2) and for distinguishing infectious from non-infectious signals from the specimen. An analysis can provide simultaneous diagnosis and genomic surveillance of a multitude of distinct specimens in a sample information. The analysis can comprise distinguishing between infectious versus infectious specimens and provide a recommendation as to how infectious the sample can be. The information on can be used to better inform the status of a subject or a location with regards to infectivity from the specimen.

Abstract

A handheld solid sample pipette device includes a pipette tube with a number of sharpened teeth adapted to pierce solid or substantially solid sample material, the pipette tube adapted to be matingly attached to a device that includes a handle, a plunger, and a piston within a shell of the device. A spring may be positioned to return the plunger to a non-depressed position following depression of the plunger. A sample of the material can be ejected from the handheld device. The handheld device may further include a shear ring apparatus, that in-turn includes a tube portion, a plurality of shear ring teeth, and a knobbed plate for rotating the shear ring. Following insertion of the pipette with sharpened teeth into the sample, the shear ring apparatus is pressed into the sample as well, such that the shear ring tube, which is slidingly engaged about the pipette tube, slides over the pipette tube into the sample. The shear ring teeth pierce the sample, and at a certain point of insertion, the shear ring apparatus is rotated in either or both a clockwise or counter-clockwise manner such that the shear ring teeth sever a portion of the material to be sampled such that the portion remains within the pipette tube, for removal, and analysis.
