“…Notably, similar to other reports in the literature [ 2 , 4 ], PBV GI were more commonly found than GII, and the phylogenetic tree analysis of their sequences confirmed the high levels of genetic diversity among PBVs GI in our samples. These results corroborate previous studies that demonstrated the high genetic diversity of PBV GI observed worldwide, with no subtypes related to host species or geographic location in general [ 15 , 18 , 19 , 20 , 27 ]. Furthermore, it has been reported that the RdRp-coding genes of dsRNA and some ssRNA viruses vary outside the conserved motif regions, explaining the diversity observed between different members of the same genogroup [ 43 ].…”

“…To date, the difference in frequency and distribution between GI and GII is considerable, with a higher prevalence of GI [ 14 , 15 , 18 , 19 ] when both genogroups can be detected in a given population and the detection of only GI in some studies [ 11 , 20 , 21 , 22 , 23 , 24 , 25 , 26 ]. However, the presence of both genogroups has also been seen in respiratory tract samples [ 14 , 15 ].…”

“…However, the presence of both genogroups has also been seen in respiratory tract samples [ 14 , 15 ]. Phylogenetic analysis of PBV GI reveals high genetic diversity between and within host species, and species-specific clustering patterns have not been observed so far [ 6 , 19 , 20 , 27 ]. Interspecies transmission events, including zoonoses, have been proposed for PBV GI [ 4 , 5 , 11 , 19 , 26 ], based on sequence identities and phylogenetic analysis; however, the use of partial gene segment-2 sequences in several of these studies make these findings inconclusive.…”

Picobirnaviruses (PBVs) have been detected in several species of animals worldwide; however, data pertaining to their presence in Australian wild and domestic animals are limited. Although PBVs are mostly found in faecal samples, their detection in blood and respiratory tract samples raises questions concerning their tropism and pathogenicity. We report here PBV detection in wild deer and cattle from southeastern Australia. Through metagenomics, the presence of PBV genogroups I (GI) and II (GII) were detected in deer serum and plasma. Molecular epidemiology studies targeting the partial RNA-dependent RNA polymerase gene were performed in a wide range of specimens (serum, faeces, spleen, lung, nasal swabs, and trachea) collected from wild deer and cattle, with PCR amplification obtained in all specimen types except lung and spleen. Our results reveal the predominance of GI and concomitant detection of both genogroups in wild deer and cattle. In concordance with other studies, the detected GI sequences displayed high genetic diversity, however in contrast, GII sequences clustered into three distinct clades. Detection of both genogroups in the upper respiratory tract (trachea and nasal swab) of deer in the present study gives more evidence about the respiratory tract tropism of PBV. Although much remains unknown about the epidemiology and tropism of PBVs, our study suggests a wide distribution of these viruses in southeastern Australia.

“…Follow-up studies showed a widespread prevalence of picobirnaviruses (PBVs) that were found in the feces of terrestrial and marine mammals, reptiles, birds Malik et al, 2014;Conceicao-Neto et al, 2016;Navarro et al, 2018), in the respiratory tract of pigs (Smits et al, 2011) and humans (Smits et al, 2012), in fish, invertebrates (Delmas et al, 2019), fungi (Yinda et al, 2018), and, according to recent data, in bacteria (Krishnamurthy, Wang, 2018). The chronology of PBV detection in humans and animals according to data from 1988 to 2018, inclusive, is presented in the Table.…”

Picobirnaviruses: prevalence, genetic diversity, detection methods

2020

View full text Add to dashboard Cite

This article presents a general overview of the prevalence, genetic diversity and detection methods of picobirnaviruses (PBVs), which are small, non-enveloped icosahedral viruses with a segmented double-stranded RNA genome consisting of two segments taxonomically related to the genus Picobirnavirus of the family Picobirnaviridae. This review of scientific papers published in 1988–2019 provides data on the PBV distribution in the nature and a broad host range. PBV infection is characterized as opportunistic, the lack of understanding of the etiological role of PBVs in diarrhea is emphasized, since these viruses are detected both in symptomatic and asymptomatic cases. The concept of PBV infection as a chronic disease caused by a long-lasting persistence of the virus in the host is considered. Such factors as stress syndrome, physiological conditions, immune status and host age at the time of primary PBV infection influence the virus detection rate in humans and animals. The possible zoonotic nature of human PBV infection is noted due to the capacity for interspecies PBV transmission acquired during evolution as a result of the reassortment of the genome segments of different viruses infecting the same host. Data providing evidence that PBVs belong to eukaryotes and a challenging hypothesis stating that PBVs are bacterial viruses are presented. The need to intensify work on PBV detection because of their wide distribution, despite the complexity due to the lack of the cultivation system, is emphasized. Two strategies of RT-PCR as main PBV detection methods are considered. The genomes of individual representatives of the genus isolated from different hosts are characterized. Emphasis is placed on the feasibility of developing primers with broader specificity for expanding the range of identifiable representatives of the genus PBV due to a huge variety of their genotypes. The importance of effective monitoring of PBV prevalence for studying the zoonotic and anthroponotic potential using metagenomics analysis is highlighted, and so is the possibility of using PBV as a marker for environmental monitoring.

“…Most of the samples used in this study were also used to investigate other viruses that cause gastroenteritis in cattle, and one of the samples was positive for both BEV and bovine Astrovirus [12]; two other samples were positive for both BEV and bovine Kobuvirus [13] and two samples were positive for both BEV and bovine Picobirnavirus [14]. It is interesting to note that in all cases of coinfection the animals were less than 8 months old.…”

Detection and molecular characterisation of bovine Enterovirus in Brazil: four decades since the first report

et al. 2019

It is suggested that bovine enteroviruses (BEV) are involved in the aetiology of enteric infections, respiratory disease, reproductive disorders and infertility. In this study, bovine faecal samples collected in different Brazilian states were subjected to RNA extraction, reverse transcription-polymerase chain reaction analysis and partial sequencing of the 5′-terminal portion of BEV. One hundred and three samples were tested with an overall positivity of 14.5%. Phylogenetic analysis clustered these BEV Brazilian samples into the Enterovirus F clade. Our results bring an important update of the virus presence in Brazil and contribute to a better understanding of the distribution and characterisation of BEV in cattle.
