Fatal Rameshwarotrema uterocrescens infection with ulcerative esophagitis and intravascular dissemination in green turtles
The trematode Rameshwarotrema uterocrescens (Digenea: Pronocephalidae) parasitizes the glands of the caudal esophagus of Chelonia mydas. In the present study, 741 C. mydas were examined, 85 animals had adult specimens of R. uterocrescens associated with necrotizing ulcerous esophagitis, of these 85,...

| description | The trematode Rameshwarotrema uterocrescens (Digenea: Pronocephalidae) parasitizes the glands of the caudal esophagus of Chelonia mydas. In the present study, 741 C. mydas were examined, 85 animals had adult specimens of R. uterocrescens associated with necrotizing ulcerous esophagitis, of these 85, 21 presented invasion of the esophageal mural vessels in the caudal esophagus of juvenile green turtles (Chelonia mydas). Necrotizing granulomatous splenitis, hepatitis, and nephritis were associated with the presence of parasites. The eggs from R. uterocrescens are birefringent under plane-polarized light, which distinguishes them from those of spirorchiid trematodes. This study contributes novel data on R. uterocrescens, methods for detecting this parasite, and demonstrates the fatal potential of parasitism in C. mydas.
