IBE (CSIC-UPF): New methods for studying parasite infection in natural populations of reptiles


News from IBE (CSIC-UPF)


In this contribution, IBE researchers describe a quantitative PCR assay for simultaneously detecting and quantifying Hepatozoon in reptiles, and compare such an approach with more traditional and routinely used multiple detection methods, namely microscopy and PCR-based approaches.

Their qPCR assay improves performance compared to other methods, and it can be easily cross-applied as a routine diagnosis to other reptile species and related haemoparasite species. As a proof of concept, they applied the qPCR assay to estimate infection patterns in two closely related and sympatric lizard species. The results show the influence of host species and sex on parasite infection, in a body size dependent manner, and highlight the importance of correctly estimate infection rates in natural populations.
