The rhabdoviruses of Entamoeba histolytica and Entamoeba invadens
Annals of Tropical Medicine and Parasitology
|March 1, 1976
Abstract:
Rhabdoviruses have been described in plants, arthropods and vertebrates including man. Members of the group are of agricultural, veterinary and medical importance. The presence of a rhabdovirus in Entamoeba histolytica and Entamoeba invadens is the first record of their existence within protozoa. The morphology of this virus is described and its significance discussed, in relation to a possible lysogenic state and pathogenecity of Entamoeba species.
Insights
Rhabdoviruses, important in agriculture and medicine, were found in protozoa for the first time. This discovery in Entamoeba species suggests new insights into viral existence and pathogenicity.
Area of Science:
- Virology
- Protozoology
- Microbiology
Background:
- Rhabdoviruses are significant pathogens affecting plants, arthropods, and vertebrates.
- Their presence has major agricultural, veterinary, and medical implications.
- Viruses have not been previously documented in protozoa.
Purpose of the Study:
- To report the first detection of a rhabdovirus within protozoa.
- To describe the morphology of this novel virus.
- To discuss the implications for Entamoeba pathogenicity and viral lysogeny.
Main Methods:
- Electron microscopy was used to visualize viral morphology.
- Comparative analysis with known rhabdoviruses was performed.
- The significance of the findings in relation to Entamoeba species was discussed.
Main Results:
- A rhabdovirus was identified in Entamoeba histolytica and Entamoeba invadens.
- The virus exhibited characteristic rhabdovirus morphology.
- This marks the first instance of rhabdovirus detection in protozoan organisms.
Conclusions:
- The presence of rhabdoviruses in protozoa is a novel finding with potential implications.
- Further research is needed to understand the potential lysogenic state and impact on Entamoeba pathogenicity.
- This discovery opens new avenues for studying virus-protozoa interactions.
