First description of pseudoparasitism by sporocysts of Monocystis sp. in nine banded armadillo, Dasypus novemcinctus (Linnaeus, 1758) - case report

ABSTRACT The present article is an account of a female of D. novemcinctus which was captured during a sanitary evaluation project of synanthropic wild animals of the municipality of Toledo/PR (license SISBIO/ICMBIO n°. 55109-1). During a physical evaluation, samples of feces were collected, after spontaneous defecation, and sent for analysis. The material was subjected to simple flotation methods in hypersaturated sodium chloride solution and centrifugal-flotation solutions in sucrose. In a test reading by the centrifugal-flotation method in sucrose, structures with approximately 10µm, biconical shape and one plate at each end were observed, compatible with sporocysts of Monocystis sp. Protozoa of the phylum Apicomplexa, like Monocystis sp., it is common parasitic annelids, such as worms. This organism is a correlate of pseudoparasitism in several animals but was not found to describe this product as an agent in nine banded armadillos, so this is a first description of Monocystis sp. in specimen of D. novemcinctus.
