|
|
mammals including pigs. Viral species involved in porcine enteric disease
|
|
complex (PEDC) include rotaviruses, coronaviruses, picornaviruses, astroviruses
|
|
and pestiviruses among others. The virome of three groups of swine samples
|
|
submitted to the Kansas State University Veterinary Diagnostic Laboratory for
|
|
routine testing were assessed, namely, a Rotavirus A positive (RVA) group, a
|
|
Rotavirus co-infection (RV) group and a Rotavirus Negative (RV Neg) group. All
|
|
groups were designated by qRT-PCR results testing for Porcine Rotavirus A, B, C
|
|
and H such that samples positive for RVA only went in the RVA group, samples
|
|
positive for >1 rotavirus went in the RV group and samples negative for all were
|
|
grouped in the RVNeg group. All of the animals had clinical enteric disease
|
|
resulting in scours and swollen joints/lameness, enlarged heart and/or a cough.
|
|
All samples were metagenomic sequenced and analyzed for viral species
|
|
composition that identified 14 viral species and eight bacterial viruses/phages.
|
|
Sapovirus and Escherichia coli phages were found at a high prevalence in RVA and
|
|
RV samples but were found at low or no prevalence in the RV Neg samples.
|
|
Picobirnavirus was identified at a high proportion and prevalence in RV Neg and
|
|
RV samples but at a low prevalence in the RVA group. A sequence analysis of the
|
|
possible host of Picobirnaviruses revealed fungi as the most likely host.
|
|
Non-rotaviral diversity was highest in RVA samples followed by RV then RV Neg
|
|
samples. Various sequences were extracted from the sample reads and a
|
|
phylogenetic update was provided showing a high prevalence of G9 and P[23] RVA
|
|
genotypes. These data are important for pathogen surveillance and control
|
|
measures</p><div class="card border-dark m-3 p-3"><a href=https://doi.org/10.1016/j.vetmic.2022.109447>https://doi.org/10.1016/j.vetmic.2022.109447</a>
