Dilistoma

Dilistoma is a genus of roundworms belonging to the phylum Nematoda. These nematodes are known to be endoparasites of reptiles, particularly lizards. The genus was first described by H.A. Baylis in 1923. Species within Dilistoma are typically found in the digestive tract of their hosts. Their life cycle often involves indirect transmission, meaning an intermediate host may be required for the parasite to complete its development and infect a new definitive host. The morphology of Dilistoma is characterized by its relatively stout body and distinct spicules in the male. Diagnosis of Dilistoma infections in reptiles is usually made through fecal examination, where the characteristic eggs of the nematode are identified. While some infections may be asymptomatic, heavy parasite burdens can lead to gastrointestinal disturbances, poor growth, and general debilitation in their reptilian hosts. Research into Dilistoma species focuses on their taxonomy, host specificity, life cycle, and the development of effective control strategies for infected populations, especially in captive reptile collections where parasitic infections can spread rapidly.
