{"abstract":"Ophidascaris robertsi is a species of parasitic roundworm found in reptilian hosts, primarily snakes. This species exhibits notable diversity in its host range, geographical distribution, and genetic variations. It parasitizes many reptile species, with specific host preferences varying by region. Researchers have identified Ophidascaris robertsi in various locations globally, shedding light on its adaptability to different host environments. Genetic diversity within this species has been a subject of study, providing insights into its evolutionary history and potential adaptations. Additionally, exploring its ecological role within reptile host populations is essential for understanding its impact on host health, reproduction, and ecosystem dynamics. Ongoing research aims to elucidate the intricate interactions and characteristics of Ophidascaris robertsi to gain a comprehensive understanding of this parasitic roundworm.","abstract_source":"original","authors":["Jeffry M.
