Reptilian viruses: isolation of parvovirus-like particles from corn snake Elapha guttata (Colubridae)
Abstract:
Parvovirus-like particles of about 30 nm in diameter were isolated from the corn snake (Elapha guttata) showing pneumonia. The DNA containing virus replicated in IgH2 cells at 30 degrees C inducing nuclear inclusion bodies.
Insights
A novel parvovirus-like particle was identified in a corn snake with pneumonia. This DNA virus replicates in cell cultures, causing characteristic nuclear inclusion bodies.
Area of Science:
- Veterinary Virology
- Herpetological Research
- Molecular Biology
Background:
- Pneumonia outbreaks in captive reptiles can cause significant morbidity and mortality.
- Etiological agents of respiratory diseases in corn snakes (Elapha guttata) require further investigation.
- Parvoviruses are small, non-enveloped viruses with single-stranded DNA genomes, known to infect various animal species.
Purpose of the Study:
- To identify the causative agent of pneumonia in a diseased corn snake.
- To characterize the morphology and replication of the isolated virus.
- To investigate the potential of the virus to infect cell cultures.
Main Methods:
- Electron microscopy was used to determine the size and morphology of viral particles.
- Virus isolation and propagation were performed in IgH2 cell lines.
- Inclusion bodies within infected cells were observed using light microscopy.
Main Results:
- Parvovirus-like particles approximately 30 nm in diameter were isolated from affected corn snakes.
- The virus demonstrated replication in IgH2 cells at 30°C.
- Infected cells exhibited characteristic nuclear inclusion bodies, indicative of viral replication.
Conclusions:
- A parvovirus-like agent is associated with pneumonia in this corn snake.
- The virus can replicate in vitro in IgH2 cells, producing observable cytopathic effects.
- Further studies are warranted to fully characterize this novel virus and its pathogenicity.
