Bourke BP, Dusek RJ, Ergunay K, Linton YM, Drovetski SV. Viral pathogen detection in U.S. game-farm mallard ( Anas platyrhynchos) flags spillover risk to wild birds. Front Vet Sci 2024; 11:1396552. [PMID: 38860005 PMCID: PMC11163284 DOI: 10.3389/fvets.2024.1396552] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/05/2024] [Accepted: 05/06/2024] [Indexed: 06/12/2024] Open
Abstract
The threat posed by emerging infectious diseases is a major concern for global public health, animal health and food security, and the role of birds in transmission is increasingly under scrutiny. Each year, millions of mass-reared game-farm birds are released into the wild, presenting a unique and a poorly understood risk to wild and susceptible bird populations, and to human health. In particular, the shedding of enteric pathogens through excrement into bodies of water at shared migratory stop-over sites, and breeding and wintering grounds, could facilitate multi-species long-distance pathogen dispersal and infection of high numbers of naive endemic birds annually. The Mallard (Anas platyrhynchos) is the most abundant of all duck species, migratory across much of its range, and an important game species for pen-rearing and release. Major recent population declines along the US Atlantic coast has been attributed to game-farm and wild mallard interbreeding and the introduction maladaptive traits into wild populations. However, pathogen transmission and zoonosis among game-farms Mallard may also impact these populations, as well as wildlife and human health. Here, we screened 16 game-farm Mallard from Wisconsin, United States, for enteric viral pathogens using metatranscriptomic data. Four families of viral pathogens were identified - Picobirnaviridae (Genogroup I), Caliciviridae (Duck Nacovirus), Picornaviridae (Duck Aalivirus) and Sedoreoviridae (Duck Rotavirus G). To our knowledge, this is the first report of Aalivirus in the Americas, and the first report of Calicivirus outside domestic chicken and turkey flocks in the United States. Our findings highlight the risk of viral pathogen spillover from peri-domestically reared game birds to naive wild bird populations.

High Prevalence of Genogroup I and Genogroup II Picobirnaviruses in Dromedary Camels. Viruses 2021; 13:v13030430. [PMID: 33800270 PMCID: PMC7999184 DOI: 10.3390/v13030430] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/29/2021] [Revised: 03/05/2021] [Accepted: 03/06/2021] [Indexed: 12/12/2022] Open
Abstract
Picobirnaviruses (PBVs) are small non-enveloped bisegmented double-stranded RNA viruses found in humans, mammals, and birds. Increasing molecular epidemiology studies suggest a high sequence diversity of PBVs in numerous hosts and the environment. In this study, using 229 fecal samples from dromedary camels in Dubai, 52.8% were positive for PBVs, of which 77.7% and 41.3% were positive for genogroup I and II, respectively, and 19.0% were positive for both genotypes. Phylogenetic analysis showed high diversity among the sequences of genogroup I and II dromedary PBVs. Marked nucleotide polymorphisms were observed in 75.5% and 46.0% of genogroup I and II RNA-dependent RNA polymerase (RdRp) sequences, respectively, suggesting the co-existence of multiple strains in the same specimen. Both high genetic diversity and prevalence of genogroup I and II PBV in dromedaries were observed. In fact, the prevalence of genogroup II PBV in dromedaries is the highest among all animals to date. The complete/near-complete core genomes of five genogroup I and one genogroup II dromedary PBVs and partial segment 1 and 2 of both genotypes were also sequenced. The dromedary PBV genome organizations were similar to those of other animals. Genetic reassortment and mutation are both important in the ecology and evolution of PBVs.

Abstract
Picobirnaviruses (PBVs) are bisegmented double-stranded RNA viruses that have been detected in a wide variety of animal species including invertebrates and in environmental samples. Since PBVs are ubiquitous in feces/gut contents of humans and other animals with or without diarrhea, they were considered as opportunistic enteric pathogens of mammals and avian species. However, the virus remains to be propagated in animal cell cultures, or in gnotobiotic animals. Recently, the classically defined prokaryotic motif, the ribosomal binding site sequence, has been identified upstream of putative open reading frame/s in PBV and PBV-like sequences from humans, various animals, and environmental samples, suggesting that PBVs might be prokaryotic viruses. On the other hand, based on the detection of some novel PBV-like RNA-dependent RNA polymerase sequences that use the alternative mitochondrial genetic code (that of mold or invertebrates) for translation, and principal component analysis of codon usage bias for these sequences, it has been proposed that PBVs might be fungal viruses with a lifestyle reminiscent of mitoviruses. These contradicting observations warrant further studies to ascertain the true host/s of PBVs, which still remains controversial. In this minireview, we have focused on the various findings that have raised a debate on the true host/s of PBVs.

Abstract
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 metagenomic analysis is highlighted, and so is the possibility of using PBV as a marker for environmental monitoring.

High detection rates and genetic diversity of picobirnaviruses (PBVs) in pigs on St. Kitts Island: Identification of a porcine PBV strain closely related to simian and human PBVs. INFECTION GENETICS AND EVOLUTION 2020; 84:104383. [PMID: 32473351 DOI: 10.1016/j.meegid.2020.104383] [Citation(s) in RCA: 7] [Impact Index Per Article: 1.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 04/15/2020] [Revised: 05/19/2020] [Accepted: 05/25/2020] [Indexed: 12/20/2022]
Abstract
We report here high rates (75.38%, 49/65) of detection of genogroup I (GI) PBVs in diarrheic pigs on the Caribbean island of St. Kitts. High quality gene segment-2 sequences encoding a significant region (~350 amino acid (aa) residues) of the putative RNA-dependent RNA polymerase (RdRp) were obtained for 23 PBV strains. The porcine PBV strains from St. Kitts exhibited high genetic diversity among themselves (deduced aa identities of 56-100%) and with other PBVs (maximum deduced aa identities of 64-97%), and retained the three domains that are conserved in putative RdRps of PBVs. The nearly complete gene segment-2 sequence (full-length minus partial 3'- untranslated region) of a porcine PBV strain (strain PO36 from St. Kitts) that is closely related (deduced aa identities of 96-97%) to simian and human GI PBVs was determined using a combination of the non-specific primer-based amplification method and conventional RT-PCR. The complete putative RdRp sequence of strain PO36 preserved the various features that are maintained in PBVs from various species. For the first time, several co-circulating PBV strains from pigs were characterized for a significant region (~350 aa) of the putative RdRp, providing important insights into the genetic diversity of PBVs in a porcine population. Taken together, these observations corroborated growing evidence that PBVs can be highly prevalent and show limited correlation globally with host species or geography. This is the first report on detection of PBVs in pigs from the Caribbean region.

Novel Picobirnaviruses in Respiratory and Alimentary Tracts of Cattle and Monkeys with Large Intra- and Inter-Host Diversity. Viruses 2019; 11:v11060574. [PMID: 31234565 PMCID: PMC6631280 DOI: 10.3390/v11060574] [Citation(s) in RCA: 18] [Impact Index Per Article: 3.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/21/2019] [Revised: 06/17/2019] [Accepted: 06/21/2019] [Indexed: 12/17/2022] Open
Abstract
Picobirnaviruses (PBVs) are mostly found in animal alimentary samples. In this study, among 576 respiratory specimens from 476 mammals and 100 chickens, genogroup I PBVs were detected in three cattle and three monkeys, and a genogroup II PBV-positive sample was collected from one cattle specimen. More than one PBV sequence type was observed in two and one genogroup I PBV-positive samples from cattle and monkeys, respectively. Twenty-four complete/near-complete segments 2 (nine from respiratory and 15 from alimentary samples) from the cattle and monkey genogroup I PBVs and one complete segment 2 from the cattle genogroup II PBV were sequenced. Similar to other studies, the cattle PBVs also showed a high diversity. In contrast, the monkey PBVs observed in this study were clustered into three distinct clades. Within each clade, all the sequences showed >99% amino acid identities. This unique phenomenon is probably due to the fact that monkeys in our locality reside in separated troops with minimal inter-troop contact.

Abstract
Picobirnavirus (PBV) is recognized as a putative cause of diarrhea and respiratory illnesses. Although PBV has been reported in several mammalian (including humans) and avian host species, data pertaining to its presence in small ruminants are limited. We report, here, PBV infection in small ruminants (ovine and caprine), in India. From January 2015 to December 2017, 400 samples were tested for the presence of PBV, using an RT-PCR assay specific for the genome segment-2. The overall rate of PBV infection was 35.75% (143/400), being higher in caprines (42.35%, 83/196) than in ovines (29.42%, 60/204). Viral genogrouping showed the predominance of PBV genogroup I (GG-I; 53.15%, 76/173), the detection of genogroup II (GG-II; 3.49%, 5/143), a concomitant infection with GG-I and GG-II (38.47%, 55/143), and un-typeable strains (4.9%, 7/143). Of note, these PBV strains exhibit low sequence identity (11.2% to 70.7%) to other reported PBV isolates from humans and other animals. By phylogenetic analysis, camel PBV isolates from the United Arab Emirates (UAE) and the reference human GG-I strain (1-CHN-97) from China were found to be the nearest neighbors of PBV strains. Furthermore, sequence analysis revealed the possible appearance of a new genogroup/genetic cluster and the existence of high genetic heterogeneity in the circulating PBV strains. Although much remains to be understood about the epidemiology and impact of PBV, the present study demonstrates the high prevalence of GG-I, the detection of GG-II, and the possible emergence of new genogroup/genetic cluster in small ruminant populations in India.

Case-Control Comparison of Enteric Viromes in Captive Rhesus Macaques with Acute or Idiopathic Chronic Diarrhea. J Virol 2017; 91:JVI.00952-17.

Abstract
Diarrhea is the major cause of non-research-associated morbidity and mortality affecting the supply of rhesus macaques and, potentially, their responses to experimental treatments. Idiopathic chronic diarrhea (ICD) in rhesus macaques also resembles ulcerative colitis, one form of human inflammatory bowel disease. To test for viral etiologies, we characterized and compared the fecal viromes from 32 healthy animals, 31 animals with acute diarrhea, and 29 animals with ICD. The overall fractions of eukaryotic viral reads were 0.063% for the healthy group, 0.131% for the acute-diarrhea group, and 0.297% for the chronic-diarrhea group. Eukaryotic viruses belonging to 6 viral families, as well as numerous circular Rep-encoding single-stranded DNA (CRESS DNA) viral genomes, were identified. The most commonly detected sequences were from picornaviruses, making up 59 to 88% of all viral reads, followed by 9 to 17% for CRESS DNA virus sequences. The remaining 5 virus families, Adenoviridae, Astroviridae, Anelloviridae, Picobirnaviridae, and Parvoviridae, collectively made up 1 to 3% of the viral reads, except for parvoviruses, which made up 23% of the viral reads in the healthy group. Detected members of the families Picornaviridae and Parvoviridae were highly diverse, consisting of multiple genera, species, and genotypes. Coinfections with members of up to six viral families were detected. Complete and partial viral genomes were assembled and used to measure the number of matching short sequence reads in feces from the 92 animals in the two clinical and the healthy control groups. Several enterovirus genotypes and CRESS DNA genomes were associated with ICD relative to healthy animals. Conversely, higher read numbers from different parvoviruses were associated with healthy animals. Our study reveals a high level of enteric coinfections with diverse viruses in a captive rhesus macaque colony and identifies several viruses positively or negatively associated with ICD.

Abstract
During 2014-2015, 270 fecal samples were collected from non-diarrheic, captive and wild African green monkeys (AGMs) on the island of St. Kitts, Caribbean region. By RNA-PAGE, picobirnaviruses (PBVs) were detected in sixteen captive AGMs. By RT-PCR and sequencing of partial gene segment-2, PBVs in 15 of these 16 samples were assigned to genogroup-I. The full-length nucleotide (nt) sequence of gene segment-2 of one of the genogroup-I PBV strains, strain PBV/African green monkey/KNA/016593/2015, was obtained using a non-specific primer-based amplification method with modifications. Gene segment-2 of strain 016593 was 1707bp long, and encoded a putative RNA-dependent RNA polymerase (RdRp) of 538aa. Furthermore, the nearly complete gene segment-2 sequences of three other AGM PBV strains were determined using primers designed from gene segment-2 sequence of 016593. The gene segment-2 of the 4 AGM PBV strains were almost identical to each other, and exhibited a high degree of genetic diversity (maximum nt and deduced aa sequence identities of 66.4% and 65.3%, respectively) with those of PBVs from other host species. The 5'- and 3'- (except for one mismatch) end nt sequences and the three domains of RdRps were retained in the AGM PBV strains. To our knowledge, this is the first report on detection, and molecular characterization of complete gene segment-2 of PBVs in vervet monkeys. PBVs were detected for the first time from the Caribbean region.

Abstract
Picobirnaviruses (PBVs) have been recognized as one of the important causal viral agents of gastroenteritis in several animal species especially in young immunocompromised hosts. In this study, we report the prevalence and molecular epidemiology of porcine PBVs from North Eastern Hilly region of India. A total of 457 fecal samples from piglets were collected from local (n = 130) and cross (n = 327) breed piglets in different seasons for 2 years. All the samples were subjected to RNA-PAGE and RT-PCR analysis for detection of PBVs. A total of 4.59 and 11.15% samples were recorded as positive for PBVs by RNA-PAGE and RT-PCR, respectively. Rate of detection was higher from diarrhoeic animals (13.56%) compared to non-diarrhoeic (4.23%) animals. Higher prevalence rate was observed from unorganized farms (14.22%) compared to organized farms (8.0%) with slightly higher detection from cross breed (11.62%) compared to local breed (10.0%). Maximum cases of piglet diarrhea associated with PBVs were detected during summer (16.4%) and winter (14.39%) seasons compared to autumn (4.80%) and spring (6.45%). All the samples were positive for PBV genogroup I only. Based upon the sequence analysis, the isolates were unique and placed in separate clad and were not closely associated with any other Indian isolates of PBVs so far. Two isolates were closely related with one Chinese isolate recovered from sewage water. This is the first systematic study of prevalence of PBVs associated with piglet diarrhea.

Abstract
In a molecular epidemiology study using 791 fecal samples collected from different terrestrial and marine mammals in Hong Kong, genogroup I picobirnaviruses (PBVs) were positive by RT-PCR targeting the partial RdRp gene in specimens from five cattle, six monkeys, 17 horses, nine pigs, one rabbit, one dog, and 12 California sea lions, with 11, 9, 23, 17, 1, 1, and 15 sequence types in the positive specimens from the corresponding animals, respectively. Phylogenetic analysis showed that the PBV sequences from each kind of animal were widely distributed in the whole tree with high diversity, sharing 47.4–89.0% nucleotide identities with other genogroup I PBV strains based on the partial RdRp gene. Nine complete segment 1 (viral loads 1.7 × 104 to 5.9 × 106/ml) and 15 segment 2 (viral loads 4.1 × 103 to 1.3 × 106/ml) of otarine PBVs from fecal samples serially collected from California sea lions were sequenced. In the two phylogenetic trees constructed using ORF2 and ORF3 of segment 1, the nine segment 1 sequences were clustered into four distinct clades (C1–C4). In the tree constructed using RdRp gene of segment 2, the 15 segment 2 sequences were clustered into nine distinct clades (R1–R9). In four sea lions, PBVs were detected in two different years, with the same segment 1 clade (C3) present in two consecutive years from one sea lion and different clades present in different years from three sea lions. A high diversity of PBVs was observed in a variety of terrestrial and marine mammals. Multiple sequence types with significant differences, representing multiple strains of PBV, were present in the majority of PBV-positive samples from different kinds of animals.

Abstract
Picobirnaviruses (PBVs) infect humans and a wide range of animals and may cause diarrhea. The aim of this study was to investigate PBV infection and its association with diarrhea. Here, seven PBV RT-PCR-positive fecal samples from diarrheic children and four fecal samples from healthy children as controls were analyzed by viral metagenomics. The results indicated that all the seven diarrheic fecal samples contain high titers of PBV sequences, while three of the controls were negative, and one had low titers of PBV. Three of the diarrheic fecal samples were also positive for other viruses, including anellovirus, human gyrovirus, human parechovirus, and porcine stool-associated circular virus. PBV sequences from the seven patients were assembled, generating seven large contigs with the complete ORF of RNA-dependent RNA polymerase (RdRp). Phylogenetic analysis of the amino acid sequences of RdRp indicated that the seven PBVs in the present study belonged to three different genogroups. Our data suggest that PBV might have been the cause of diarrhea in these seven children.

Abstract
Picobirnavirus (PBV) belongs to the family Picobirnaviridae. PBV are a group of emerging non-enveloped viruses, with a bisegmented double-stranded RNA genome that can infect a wide range of hosts. This study reports the occurrence of PBV in fecal samples from five Brazilian dairy cattle herds. From the 289 stool samples of individual calves analyzed by silver-stained polyacrylamide gel electrophoresis (ss-PAGE) the PBV was detected in 8.3 % (24/289), of which 10.2% (18/176) had diarrheic consistency. Of the 24 positive samples in ss-PAGE, 5 (20.8%) of them showed a small electrophoretic profile and 19 (79.2%) samples had large profile. From the 24 positives samples by ss-PAGE, 15 (62.5%) were successfully amplified (201 bp) using GI specific primers targeting the RdRp gene of PBV. The analysis of nucleotide identity matrix revealed that the bovine PBV strain identified in this study, showed the highest nucleotide identity (81%) with PBV strain detected in turkey (MD-2010/HM803965). This is the first nucleotide sequence of a bovine PBV strain in the American continent and the first detection of small genome profile of PBV-like strains in bovine hosts.

Abstract
Wastewater contains numerous viruses. In this study, picobirnaviruses (PBVs) were detected in the stream of a wastewater treatment plant in Changsha, Hunan province, China, and evolutionary analysis of the isolated PBVs was performed. The phylogenetic tree revealed that the PBVs were highly divergent and could be classified into six distinct groups according to their hosts. Among these groups, pairwise comparison of the six groups revealed that the nucleotide distance of group 4 (bootstrap value = 0.92; nucleotide identity = 94%) was the largest. Thus, group 4 might represent a new division of PBVs. Comprehensive analysis of the obtained PBV sequences to investigate their evolutionary history and phylodynamics revealed that group 5 (PBVs from monkey) exhibited maximum polymorphism (K = 30.582, S = 74, η = 98, Pa = 47) and lowest nucleotide substitutions per site per year (6.54E-3 subs per site per year), except group 4. Maximum clade credibility tree indicated that group 5 appeared earlier than the other groups. In conclusion, this study detected PBVs in treated wastewater in China, and identified a new PBV group. Furthermore, among these PBVs, group 5 was found to survive longer and present a balance between PBVs and their monkey host.

Abstract
The full-length genome sequence of a porcine picobirnavirus (PBV) detected in Italy in 2004 was determined. The smaller (S) genome segment was 1730 nt, coding for a putative RNA-dependent RNA polymerase. Two distinct subpopulations of larger (L) genome segment (LA and LB) were identified in the sample, with the sizes ranging from 2351 to 2666 nt. The ORF1, coding for a protein of unknown function, contained a variable number of repetitions of the ExxRxNxxxE motif. The capsid protein-coding ORF2 spanned nt 810–2447 in the LB variants and started at nt 734 in the LA variants. However, a termination codon was present only in one of all the LA segment variants. Three-dimensional modelling of the porcine PBV capsids suggested structural differences in the protruding domain, tentatively involved as antigens in the humoral immune response. Altogether, these findings suggest the simultaneous presence of two different PBV strains sharing the same S segment but displaying genetically diverse L segments. In addition, the sample probably contained a mixture of PBVs with aberrant RNA replication products. Altered structure in the L segments could be tolerated and retained in the presence of functionally integer-cognate genes and represents a mechanism of virus diversification.

Abstract
Picobirnavirus (PBV) which has been included in the list of viruses causing enteric infection in animals is highly versatile because of its broad host range and genetic diversity. PBVs are among the most recent and emerging small, nonenveloped viruses with a bisegmented double-stranded RNA genome, classified under a new family “Picobirnaviridae.” PBVs have also been detected from respiratory tract of pigs, but needs further close investigation for their inhabitant behavior. Though, accretion of genomic data of PBVs from different mammalian species resolved some of the ambiguity, quite a few questions and hypotheses regarding pathogenesis, persistence location, and evolution of PBVs remain unreciprocated. Evolutionary analysis reveals association of PBVs with partitiviruses especially fungi partitiviruses. Although, PBVs may have an ambiguous clinical implication, they do pose a potential public health concern in humans and control of PBVs mainly relies on nonvaccinal approach. Based upon the published data, from 1988 to date, generated from animal PBVs across the globe, this review provides information and discussion with respect to genetic analysis as well as evolution of PBVs of animal origin in relation to human strains.

Abstract
Picobirnavirus (PBV) belongs to the family Picobirnaviridae. Picobirnaviruses contain a bisegmented dsRNA genome that is non-enveloped. A total of 85 pooled faecal samples were collected from the poultry of 37 farms from the Metropolitan Mesoregion of Belém (MMB), Pará state, Brazil. The viral RNA from each sample was analysed by PAGE and reverse transcriptase PCR (RT-PCR). For each county affected, at least one positive sample was selected, cloned and sequenced. The samples showed a positivity of 15.3 % (13/85) by PAGE and 49.4 % (42/85) by RT-PCR. Sequencing of these strains demonstrated a considerable RdRp gene heterogeneity that ranged from 56.1 to 100 % at the nucleotide level compared with prototypes of different species and water sewage, and from 50.3 to 100 % among themselves. Avian picobirnavirus (AvPBV) was detected in MMB broiler farms and showed a heterogeneous relationship with the prototypes used. This report includes what is believed to be the first gene sequencing of AvPBV in Brazilian broiler chickens.
