Abstract:
This study reports a genome of psittaciform chaphamaparvovirus 4 (PsChPV-4) and a beak and feather disease virus (BFDV) detected in fecal materials of rose-ringed parakeet. The genomes of PsChPV-4 and BFDV were 4,304 and 2,009 bp long, respectively, and both genomes possessed a genomic structure consistent with their respective genera.
Insights
This study identified the genomes of psittaciform chaphamaparvovirus 4 (PsChPV-4) and beak and feather disease virus (BFDV) in rose-ringed parakeet feces. Their genomic structures align with their known genera.
Area of Science:
- Virology
- Genomics
- Avian Health
Background:
- Psittaciform chaphamaparvovirus 4 (PsChPV-4) and beak and feather disease virus (BFDV) are known avian viruses.
- Parrot species are susceptible to various viral infections.
- Fecal samples are a non-invasive method for pathogen detection.
Purpose of the Study:
- To report the genome sequences of PsChPV-4 and BFDV found in a rose-ringed parakeet.
- To characterize the genomic structure of these detected viruses.
- To contribute to the understanding of parvovirus diversity in psittacine birds.
Main Methods:
- Viral DNA extraction from fecal samples.
- Whole-genome sequencing of detected viruses.
- Bioinformatic analysis of viral genomes and comparison to reference sequences.
Main Results:
- The complete genome of PsChPV-4 was sequenced (4,304 bp).
- The complete genome of BFDV was sequenced (2,009 bp).
- Both viral genomes exhibited structures consistent with their respective genera.
Conclusions:
- The study successfully sequenced and characterized PsChPV-4 and BFDV genomes from a single avian host.
- The findings confirm the presence of these viruses in rose-ringed parakeets.
- This genomic data aids in understanding parvovirus evolution and host-virus interactions in parrots.
