CONFIRMATION OF SARCOCYSTIS INFECTIONS IN TONGUES OF FLORIDA PANTHERS (PUMA CONCOLOR CORYI)
The Journal of Parasitology
|May 21, 2026
Summary
Sarcocystis parasites were identified in Florida panthers, with one species confirmed as Sarcocystis felis. Further research is needed to identify a second, distinct Sarcocystis type found in these wild felids.
Area of Science:
- Veterinary Parasitology
- Wildlife Disease Ecology
- Molecular Biology
Background:
- Sarcocystis species are protozoan parasites with complex life cycles involving wild and domestic animals.
- Florida panthers (Puma concolor coryi) are an endangered subspecies facing various health challenges.
- Understanding parasite prevalence in apex predators is crucial for ecosystem health.
Purpose of the Study:
- To determine the prevalence and identify Sarcocystis species in Florida panther tongues.
- To characterize the morphology and molecular genetics of detected Sarcocystis.
- To assess the potential impact of Sarcocystis on panther health.
Main Methods:
- Necropsy and light microscopy of tongue tissues from Florida panthers.
- Morphological analysis of sarcocysts, including sarcocyst wall structures.
- Molecular identification using the ITS1 gene sequencing.
Main Results:
- Sarcocysts were detected in 42.6% (46/108) of Florida panthers examined.
- Two distinct morphological types of sarcocysts were observed: one with serrated walls and one with smooth walls.
- Molecular analysis confirmed the serrated type as Sarcocystis felis.
Conclusions:
- Sarcocystis felis is present in Florida panthers.
- An unidentified Sarcocystis species with smooth-walled sarcocysts also infects this population.
- Further molecular and morphological studies are required to fully characterize the novel Sarcocystis species.
