Captive populations experience periodic crashes, some of which have resulted in extinction. Pathologic investigations of the last individuals of a species that had undergone such a crash (Partula turgida) showed infection with a protozoan parasite as the cause of death. The parasite was identified as a member of the microsporidian genus Steinhausia, other members of which are known to cause mortality in aquatic pulmonate snails. We believe this is the first definitive report of an infectious disease causing the extinction of a species.

Las poblaciones cautivas experimentan colapsos periódicos, algunos de los cuales han resultado en extinciones. Investigaciones patológicas de los últimos individuos de una especie que ha pasado por este tipo de colapso (Partula turgida) muestran infecciones de un protozoario parásito como la causa de su muerte. El parásito ha sido identificado como un miembro del género Steinhausia, otros miembros de este género han sido identificados como los causantes de mortalidades en caracoles pulmonados acuáticos. Creemos que este es un reporte definitivo de una enfermedad infecciosa causante de la extinción de una especie.
