Multiplex detection of respiratory pathogens

Described are kits and methods useful for detection of respiratory pathogens (influenza A (including subtyping capability for H1, H3, H5 and H7 subtypes) influenza B, parainfluenza (type 2), respiratory syncytial virus, and adenovirus) in a sample. Genomic sequence information from the respiratory pathogens was analyzed to identify signature sequences, e.g., polynucleotide sequences useful for confirming the presence or absence of a pathogen in a sample. Primer and probe sets were designed and optimized for use in a PCR based, multiplexed Luminex assay to successfully identify the presence or absence of pathogens in a sample.

The NS1 protein of influenza virus is a key virulent element with multi-functional roles in virus replication and acts as a strong interferon (IFN) antagonist. A live attenuated virus (LAIV) is provided using a master backbone, which contains the influenza B (HK8038) virus and includes a deletion of the NSI coding region (DelNS1). The LAIV is based on novel adaptive mutations, which support DelNS1 influenza B live attenuated virus (LAIV) replication in vaccine producing cells. DelNS1 influenza B LAIV shows spontaneous cold adaption with preference to grow at 30-33° C. but restriction at 37-39° C. The LAIV can be used to protect a subject, against a lethal challenge of antigenic distant influenza B viruses. DelNS1 LAIV with adaptive mutations for growing in vaccine producing systems is an important strategy for making highly attenuated and immunogenic live attenuated influenza vaccines with the ability to induce broad cross protective immunity for seasonal influenza.
