abstract = {Traditional diagnostic assays often lack sensitivity and
can be difficult to multiplex across many pathogens.
Next-generation sequencing (NGS) can overcome some of these
problems but has limited application in the detection of
low-copy-number pathogens in complex samples. Targeted
genome capture (TGC) utilizes oligonucleotide probes to
enrich specific nucleic acids in heterogeneous extracts and
can therefore increase the proportion of NGS reads for
low-abundance targets. While earlier studies have
demonstrated the utility of this technology for detection of
novel pathogens in human clinical samples, the capacity and
practicality of TGC-NGS in a veterinary diagnostic setting
have not yet been evaluated. Here we report the use of
TGC-NGS assays for the detection and characterization of
diverse feline pathogen taxa. We detected 31 pathogens
comprising nine pathogen taxa in 28 felid samples analyzed.
This included 20 pathogens detected via traditional PCR and
11 additional pathogens that had not been previously
detected in the same samples. Most of the pathogens detected
were sequenced at sufficient breadth and depth to
confidently classify them at the species or subspecies
level. Target nucleic acids were enriched from a low of
58-fold to 56 million-fold relative to host nucleic acids.
Despite the promising performance of these assays, a number
of pathogens detected by conventional PCR or serology were
not isolated by TGC-NGS, suggesting that further validation
is required before this technology can be used in lieu of
quality-controlled standard assays. We conclude that TGC-NGS
offers great potential as a broad multiplex pathogen
characterization assay in veterinary diagnostic and research
settings.},
