Hypothesis
How do different strains of Wolbachia affect the immunocompetence and survival of their host, Armadillidium vulgare?
Conclusion
Different strains of Wolbachia induce variation in the immunocompetence and survival of their host, A. vulgare.
Supporting Evidence
- Individuals infected with wVulC had lower haemocyte densities and higher septicaemia compared to those infected with wVulM.
- C females had a significantly shorter lifespan than A females.
- Haemocyte density was significantly higher in asymbiotic females compared to those infected with either Wolbachia strain.
Takeaway
This study shows that the bacteria Wolbachia can make their host isopods sick, depending on the strain they carry.
Methodology
The study involved sampling gravid females of A. vulgare, assessing their infection status, and comparing various health metrics across different Wolbachia strains.
Potential Biases
Potential bias due to the specific environmental conditions of the laboratory setting.
Limitations
The study was limited to one host species and specific Wolbachia strains, which may not represent broader patterns.
Participant Demographics
Gravid females of Armadillidium vulgare from a natural park in Western France.
