Histología ovárica y desarrollo folicular de la serpiente Amerotyphlops Brongersmianus (Scolecophidia: Typhlopidae)

Abstract

El ovario es una estructura muy dinámica la cual se modifica estacionalmente a lo largo del ciclo reproductor de las hembras. El desarrollo folicular se produce en dos etapas: previtelogénica y vitelogénica donde ocurren importantes cambios en la estructura de los ovocitos, así como también del epitelio folicular. El conocimiento de estos eventos es fundamental para interpretar las características reproductoras de una especie. Basado en ejemplares pertenecientes a una Colección Herpetológica, en este trabajo se describió la morfología ovárica y folicular de hembras juveniles y adultas de la serpiente Amerotyphlops brongersmianus (Scolecophidia: Typhlopidae), una especie con hábitos semifosoriales, común en el nordeste de Argentina. Los ovarios de las hembras juveniles presentaron nidos germinales con ovogonias y ovocitos en folículos en estadios iniciales de la previtelogénesis. Los ovarios de las hembras adultas presentaron folículos es diferentes estadios de la previtelógenesis y vitelogénesis, nidos germinales y folículos en proceso de atresia. Este trabajo representa la primera contribución al conocimiento de la morfología ovárica de A. brongersmianus y pone de manifiesto un patrón morfológico similar al de otras especies estudiadas del Orden Squamata.
