ABSTRACT

Crocodiles are susceptible to infection with a wide array of external and internal gastrointestinal helminths, yet little is known on the histopathology following infection or the effects of these parasites. The present study was aimed at evaluating the impact of infection by Ortleppascaris sinensis (Nematoda: Ascaridoidea) on the stomach of captive Alligator sinensis. The histological examination of the stomach revealed presence of superficial ulcer in mucous layer and granulomatous inflammation in submucous layer at entire gastric walls of the Alligator sinensis. Our findings also confirm that development of Ortleppascaris sinensis is in close association with the wall of the stomach.

Key words: Histopathology. Ortleppascaris sinensis. Stomach.


RESUMEN

Los cocodrilos son susceptibles a la infección con una amplia gama de helmintos gastrointestinales externos e internos; sin embargo, poco se sabe sobre la histopatología tras la infección o los efectos de estos parásitos. El presente estudio pretende evaluar el impacto de la infección por Ortleppascaris sinensis (Nematodos: Ascaridoidea) sobre el estómago del Alligator sinensis en cautividad. El examen histológico del estómago reveló la presencia de úlcera superficial en la capa mucosa e inflamación granulomatosa en la capa submucosa del conjunto de las paredes gástricas del Alligator sinensis. Nuestros resultados confirman también que el desarrollo de Ortleppascaris sinensis está estrechamente relacionado con la pared del estómago.

Palabras clave: Histopatología. Ortleppascaris sinensis. Estómago.
