    First report of a naturally patent infection of Angiostrongylus costaricensis in a dog
    (Veterinary Parasitology, 2015-09-15) Alfaro-Alarcón, Alejandro; VENEZIANO, Vincenzo; Galiero, Giorgio; Cerrone, Anna; Gutierrez, Natalia; Chinchilla, Adriana; Annoscia, Giada; Colella, Vito; Dantas Torres, Filipe; Otranto, Domenico; Santoro, Mario
    Angiostrongylus costaricensis is the zoonotic agent of abdominal angiostrongyliasis in several countries in North and South America. Rodents are recognized as the main definitive hosts of A. costaricensis, but other wildlife species can develop patent infections. Although, several human cases have been described in the literature, the role of domestic animals in the epidemiology of the infection is not clear. Here we review the literature available on A. costaricensis in mammals and describe the first confirmed fatal case of abdominal angiostrongyliasis in a 4-month-old dog, presented with intestinal perforation, peritonitis and faecal shedding of first-stage larvae. Parasite identity was confirmed by morphology, histology and molecular characterization of target genes. This is the first record of a naturally infected dog acting as a definitive host for A. costaricensis. These data suggest that dogs may potentially spread this parasite in urbanized areas.

    The white-nosed coati (Nasua narica) is a naturally susceptible definitive host for the zoonotic nematode Angiostrongylus costaricensis in Costa Rica
    (Veterinary Parasitology, 2016-09-15) Hagnauer, Isabel; Santoro, Mario; Alfaro-Alarcón, Alejandro; VENEZIANO, Vincenzo; Cerrone, Anna; Latrofa, Maria Stefania; Otranto, Domenico; Jiménez-Soto, Mauricio
    Angiostrongylus costaricensis (Strongylida, Angiostrongylidae) is a roundworm of rodents, which may cause a severe or fatal zoonosis in several countries of the Americas. A single report indicated that the white-nosed coati (Nasua narica), acts as a potential free-ranging wildlife reservoir. Here we investigated the prevalence and features of A. costaricensis infection in two procyonid species, the white-nosed coati and the raccoon (Procyon lotor) from Costa Rica to better understand their possible role in the epidemiology of this zoonotic infection. Eighteen of 32 (56.2%) white-nosed coatis collected between July 2010 and March 2016 were infected with A. costaricensis but none of 97 raccoons from the same localities were diagnosed with this infection. First-stage larvae of A. costaricensis were obtained from feces of 17 fresh white-nosed coati carcasses by Baermann technique. Parasite identity was confirmed by morphology, histology and molecular characterization of target genes. These data demonstrate that the white-nosed coati is a naturally susceptible definitive host for A. costaricensis in Costa Rica contrary to findings in the raccoon.
