3.2.3 Chaphamaparvovirus and Dependoparvovirus
Chaphamaparvovirus is a recently proposed genus in theParvoviridae family, subfamily Hamaparvovirinae that
includes species isolated from pigs, dogs, rodent, duck, owl and bat
hosts (Palinski et al., 2016; Palombieri et al., 2020; Roediger et al.,
2018; Souza et al., 2017; Vibin et al., 2020; Yang et al., 2016). Feline
chaphamaparvovirus was recently discovered in the faeces of
shelter-housed cats with diarrhoea (Li et al., 2020). We did not detect
feline chaphamaparvovirus contigs in any of the FPV-case libraries.
However, read abundance data showed the presence of feline
chaphamaparvovirus DNA in FPV-case samples at relatively low levels
(maximum 25 reads in the metagenomic library). By contrast, in the
healthy controls feline chaphamaparvovirus contigs were detected in 6/36
libraries (p = 0.0724) (Figure 2). In the six sequencing libraries,
abundance values ranged from 61 to 6,749 RPM for the metagenomic
libraries and 87 and 4,648 RPM for the metatranscriptomic libraries.
Dependoparvovirus, another genus in the Parvoviridaefamily, includes the species Feline dependoparvovirus, previously
detected in a single cat in the same shelter cat population in which
feline chaphamaparvovirus was discovered (Li et al., 2020). HereFeline dependoparvovirus DNA was detected in 1/23 FPV-case
libraries and 5/36 healthy control libraries (p=0.3886).
