The present invention includes compositions, including epitope megapools, and methods for detecting the presence of: a Bordetella or an immune response relevant to a Bordetella infection including T cells responsive to one or more Bordetella peptides or proteins comprising, consisting of, or consisting essentially of: one or more amino acid sequences, fusion proteins, a pool of 2 or more peptides, or polynucleotides that expression the amino acid sequences selected from those set forth in any one of Tables 1-20 (SEQ ID NOS: 1 to 2598). The invention further provides vaccines, diagnostics, therapies, and kits, comprising such proteins or peptides.

A nasal irrigation diagnostic assembly comprising an irrigation device including a fluid collection portion structured to retain a biological sample, in the form of waste solution from the nasal cavity resulting from irrigation. A detection member disposed on said irrigation device is exposed to the biological sample and is structured to determine the existence of at least one analyte within the biological sample of the waste solution. The detection member comprises a plurality of detection zones individually structured to analyze the biological sample upon engagement therewith, wherein said plurality of zones include at least a reaction zone and a detection zone, which respectively include reagents cooperatively and collectively formulated to detect the existence of the at least one analyte within biological sample of the waste solution. A control zone may also be included to indicate the intended operability of at least the detection member.
