Detection of parechovirus A in respiratory, gastrointestinal, and neurological clinical samples of pediatric patients from Panama (2014-2015). Virol J 2023; 20:302. [PMID: 38115118 PMCID: PMC10731877 DOI: 10.1186/s12985-023-02268-9] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/01/2023] [Accepted: 12/11/2023] [Indexed: 12/21/2023] Open
Abstract
Parechovirus A (PeV-A, Parechovirus, Picornaviridae) are human pathogens associated with mild to severe gastrointestinal and respiratory diseases in young children. While several studies have investigated the association of PeV-A with human disease, little is known about its epidemiology or detection in Latin America. Between the years 2014 and 2015, a total of 200 samples were collected from Panamanian pediatric patients aged < 16 years old exhibiting symptoms associated with respiratory (n = 64), gastrointestinal (n = 68), or neurological (n = 68) diseases. These samples were gathered from patients who had previously received negative diagnoses for the main respiratory viruses, rotavirus, and neurological viruses like herpes virus, enterovirus, and cytomegalovirus. The presence of PeV-A was analyzed by real time RT-PCR.Eight positive PeV-A infections (4.0%, 95% CI: 1.7 to 7.7) were detected: two in respiratory samples (3.0%, 95% CI: 0.3 to 10.8), five in gastrointestinal samples (7.3%, 95% CI: 2.4 to 16.3), and one in cerebrospinal fluid (1.5%, 95% CI: 1.4 to 7.9). The study provides evidence of PeV-A circulation in Panama and the data collectively, remarked on the importance of considering PeV-A in the Panamanian pediatric diagnostic landscape, especially when conventional testing for more common viruses yields negative results.

Abstract
Parechoviruses belong to the genus Parechovirus within the family Picornaviridae and are non-enveloped icosahedral viruses with a single-stranded RNA genome. Parechoviruses include human and animal pathogens classified into six species. Those that infect humans belong to the Parechovirus A species and can cause infections ranging from mild gastrointestinal or respiratory illness to severe neonatal sepsis. There are no approved antivirals available to treat parechovirus (nor any other picornavirus) infections. In this parechovirus review, we focus on the cleaved protein products resulting from the polyprotein processing after translation comparing and contrasting their known or predicted structures and functions to those of other picornaviruses. The review also includes our original analysis from sequence and structure prediction. This review highlights significant structural differences between parechoviral and other picornaviral proteins, suggesting that parechovirus drug development should specifically be directed to parechoviral targets.

Zhou L, Huo X, Liu B, Wu H, Feng J. Comparative Analysis of the Gut Microbial Communities of the Eurasian Kestrel ( Falco tinnunculus) at Different Developmental Stages. Front Microbiol 2020; 11:592539. [PMID: 33391209 PMCID: PMC7775371 DOI: 10.3389/fmicb.2020.592539] [Citation(s) in RCA: 12] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/07/2020] [Accepted: 11/18/2020] [Indexed: 12/21/2022] Open
Abstract
The gut microflora play a very important role in the life of animals. Although an increasing number of studies have investigated the gut microbiota of birds in recent years, there is a lack of research work on the gut microbiota of wild birds, especially carnivorous raptors, which are thought to be pathogen vectors. There are also a lack of studies focused on the dynamics of the gut microbiota during development in raptors. In this study, 16S rRNA gene amplicon high-throughput sequencing was used to analyze the gut microbiota community composition of a medium-sized raptor, the Eurasian Kestrel (Falco tinnunculus), and to reveal stage-specific signatures in the gut microbiota of nestlings during the pre-fledging period. Moreover, differences in the gut microbiota between adults and nestlings in the same habitat were explored. The results indicated that the Eurasian Kestrel hosts a diverse assemblage of gut microbiota. Proteobacteria, Firmicutes, Actinobacteria, and Bacteroidetes were the primary phyla shared within the guts of adults and chicks. However, adults harbored higher abundances of Proteobacteria while nestlings exhibited higher abundances of Firmicutes and Actinobacteria, and consequently the majority of dominant genera observed in chicks differed from those in adults. Although no significant differences in diversity were observed across the age groups during nestling ontogeny, chicks from all growth stages harbored richer and more diverse bacterial communities than adults. In contrast, the differences in gut microbial communities between adults and younger nestlings were more pronounced. The gut microbes of the nestlings in the last growth stage were converged with those of the adults. This study provides basic reference data for investigations of the gut microbiota community structure of wild birds and deepens our understanding of the dynamics of the gut microflora during raptor development.

Abstract
A novel picornavirus, referred to as Duck/FC22/China/2017, was isolated from breeding ducks in China and genetically characterized by conducting metagenomics studies. The complete genome consists of a single-stranded, positive-sense RNA made up of 7448 nucleotides (nt) and follows the common picornavirus genome layout: 5' UTR-VP0-VP3-VP1-2A-2B-2C-3A-3B-3C-3D-3' UTR. A typical type-IV internal ribosomal entry site and a conserved 'barbell-like' structure were identified in the 5' UTR and 3' UTR, respectively. The unique 6423-nt open reading frame was predicted to encode a 2141-amino-acid (aa) polyprotein precursor. A pairwise aa sequence identity comparison and phylogenetic analysis revealed that Duck/FC22/China/2017 is closely related to duck aalivirus, duck hepatitis A virus, turkey avisivirus, and red-crowned crane picornavirus.

Abstract
Picornaviruses are small, nonenveloped, icosahedral RNA viruses with positive-strand polarity. Although the vast majority of picornavirus infections remain asymptomatic, many picornaviruses are important human and animal pathogens and cause diseases that affect the central nervous system, the respiratory and gastrointestinal tracts, heart, liver, pancreas, skin and eye. A stunning increase in the number of newly identified picornaviruses in the past decade has shown that picornaviruses are globally distributed and infect vertebrates of all classes. Moreover, picornaviruses exhibit a surprising diversity of both genome sequences and genome layouts, sometimes challenging the definition of taxonomic relevant criteria. At present, 35 genera comprising 80 species and more than 500 types are acknowledged. Fifteen species within five new and three existing genera have been proposed in 2017, but more than 50 picornaviruses still remain unassigned.
