Pathogen transcriptional profile in nasopharyngeal aspirates of children with acute respiratory tract infection.

ABSTRACT:

Background

Acute respiratory tract infections (ARI) present a significant morbidity and pose a global health burden. Patients are frequently treated with antibiotics although ARI are most commonly caused by virus, strengthening the need for improved diagnostic methods.

Objectives

Detect viral and bacterial RNA in nasopharyngeal aspirates (NPA) from children aged 6-23 months with ARI using nCounter.

Study design

A custom-designed nCounter probeset containing viral and bacterial targets was tested in NPA of ARI patients.

Results

Initially, spiked control viral RNAs were detectable in ≥6.25 ng input RNA, indicating absence of inhibitors in NPA. nCounter applied to a larger NPA sample (n=61) enabled the multiplex detection of different pathogens: RNA viruses Parain
