A case of natural infection with Dirofilaria immitis in a coati (Nasua narica) from Mexico

This paper aims to describe the natural infection with in (white-nosed coati) from Yucatán, Mexico. Two carcasses of were collected on a highway that crosses through a dense forest with patches used for agriculture and livestock activities. We performed necropsies, and two female adult nematode parasites from the heart of one specimen were collected and preserved for their molecular identification using a conventional PCR directed at a fragment of the small subunit (18S) ribosomal RNA ( rRNA) gene. Bioinformatic analysis showed a similarity of 99 % with three sequences from (two from Japan). Additionally, we performed a phylogenetic tree with the recovered sequence. All these analyses showed that is present in from Mexico. The transmission of toward populations of sp. may be due to indirect and accidental contact with domestic dogs or wild canids that share the same environment.
