Angiostrongylus vasorum and Aelurostrongylus abstrusus: Neglected and underestimated parasites in South America

et al. 2018

View full text Add to dashboard Cite

The gastropod-borne nematodes Angiostrongylus vasorum and Aelurostrongylus abstrusus are global causes of cardio/pulmonary diseases in dogs and cats. In the last decade, the number of reports on canine and feline lungworms has increased in several areas of Europe and North America. The unspecific clinical signs and prolonged course of these diseases often renders diagnosis challenging. Both infections are considered as emerging and underestimated causes of disease in domestic pets. In South America, little information is available on these diseases, apart from occasional reports proving the principle presence of A. vasorum and A. abstrusus. Thus, the purpose of this review is to summarize reports on infections in both domestic and wildlife animals in South America and to increase the awareness on gastropod-borne metastrongyloid parasites, which also include important zoonotic species, such as A. cantonensis and A. costaricensis. This review highlights the usefulness of diagnostic tools, such as the Baermann funnel technique, serology and PCR, and proposes to include these routinely on cases with clinical suspicion for lungworm infections. Future national epidemiological surveys are recommended to be conducted to gain a deeper insight into the actual epidemiological situation of gastropod-borne parasitoses in South America.

“…For instance, A. cantonensis has been diagnosed through histopathological evaluation in the North American opossum ( Didelphis virginiana ), grey-headed flying fox ( Pteropus poliocephalus ), black-and-white ruffed lemur ( Varecia variegata ) and in the miniature horse ( Equus ferus caballus ) (Reddacliff et al ., 1999; Costa et al ., 2000; Kim et al ., 2002); as well as through ELISA and Western blot in domestic dogs ( Canis lupus familiaris ) (Lunn et al ., 2012). Additionally, A. vasorum has been diagnosed through coproparasitological analysis in domestic cats ( Felis domesticus ) and in the European badger ( Meles meles ) (Kamenov et al ., 1999; Torres et al ., 2004), through electron microscopy in the wolf ( C. lupus ) and in the crab-eating fox ( Cerdocyon thous ) (Segovia et al ., 2001; Duarte et al ., 2007; Vieira et al ., 2017); as well as through histopathology in the wolf ( C. lupus ), mustelids ( Mustela erminea , Mustela nivalis , Mustela putorius ), domestic dog ( C. lupus familiaris ), red fox ( Vulpes vulpes ) and in the crab-eating fox ( C. thous ) (Denk et al ., 2009; Eleni et al ., 2014; Santoro et al ., 2015; Simpson et al ., 2016; Ferreira-Júnior et al ., 2017). Furthermore, the wide variety of definitive and accidental hosts are considered a risk to people who live in areas where such species are affected (Ma et al ., 2013).…”

Angiostrongylosis inCerdocyon thous(crab-eating fox) andLycalopex gymnocercus(Pampas fox) in Southern Brazil

The objective of this study was to identify species of Angiostrongylus spp. infecting wild carnivores in Southern Brazil, as well as to describe gross and histopathological findings associated with the infection. Necropsy was conducted in 16 wild carnivores parasitized by Angiostrongylus spp. Analysed lungs revealed multifocal dark-red areas of consolidation; in one case, multifocal firm white nodules spread in all pulmonary lobes were observed. In one animal, a focally extensive area of malacia associated with haemorrhage was noted in the encephalon. Histologically, multifocal granulomatous pneumonia or bronchopneumonia, associated with eggs and larvae in blood vessels, lung interstitium, alveoli, and sometimes in bronchi and bronchioles was observed. Adult nematodes were seen within blood vessels. The lesion observed in the brain was characterized as a focally extensive area of malacia associated with gitter cells, haemorrhage, thrombosis and a free intralesional larva. Through molecular techniques, seven positive samples of Angiostrongylus cantonensis were obtained, including the brain sample, and a positive sample of Angiostrongylus vasorum-like, all in Cerdocyon thous. The positive sample for A. vasorum showed 97% similarity with sequences deposited in GenBank, suggesting a new species or subspecies of Angiostrongylus sp. Infection of Lycalopex gymnocercus by Angiostrongylus spp. was confirmed by histological evaluation.

Abstract The aim of the present study was to evaluate the state of knowledge about the helminthology of wild mammals in Argentine Patagonia and its link with the conservation of parasite species and biodiversity. To this end, the information included in the previously reported checklist of the helminths found in terrestrial wild mammals of Argentine Patagonia was completed and updated. The methodology used for the search was the same as that previously used, with slight modifications. Eighty-two species of mammals currently inhabit the region, and an additional six species are considered to have become extinct before the 20th century. The reports used to complete and update the information correspond to research done since 2015 to date. Considering the number of records analysed in the previously reported checklist and those of the current update, a total of 1918 helminthological reports for current Patagonian mammals and 2141 on mammal species that inhabited Patagonia before the 20th century were accounted for. It is important to point out that 41% of the 82 species of wild mammals currently inhabiting Patagonia have not been studied helminthologically; 38% of these without helminthological records are either threatened or do not have categorization, and 79% of mammals without helminthological studies have some degree of endemism. Therefore, in order to evaluate conservation priorities, the information about the parasitic richness in Patagonian wild mammals should be substantially increased, especially in those endangered or endemic.
