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

Abstract: 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 inf… Show more

“…Although, domestic and wild cats have been known to be clinically affected with A. chabaudi, thereby showing granulomatous pneumonia, parenchymal hemorrhages and alveolar emphysema [20]; a demonstration of A. chabaudi adults, larvae or associated leptomeningeal lesions have not been observed in feline angiostrongylosis in wild Chilean kodkods [21]. Three of the ten felines examined in this study were positive for infections with A. abstrusus, a metastrongyloid nematode that also belongs to the family Angiostrongylidae and reported to occur in domestic and wild cats with symptoms varying from subclinical to fatal respiratory diseases [22,23]. Although, the Baermann funnel technique is the most frequently used method for the diagnosis of metastrongyloid infections, this technique has failed so far to detect patent G. paralysans infections, particularly during periods when there is no larval removal independent of the existence of clinical signs [8,24].…”

“…As parasitoses respiratórias em gatos são causadas por nematódeos pulmonares com destaque a um metastrongilídeo potencialmente patogênico, Aelurostrongylus abstrusus (DIAKOUet al, 2015). Este, tem ganhado a atenção da comunidade veterinária devido à sua disseminação além das fronteiras de áreas endêmicas conhecidas, principalmente em países europeus e na América do Norte, e atingindo felinos mundialmente (PENAGOS-TABARES et al, 2018), incluindo o Brasil. O fato de constituírem um desafio a nível de diagnóstico e representarem um risco para a saúde animal contribui também para o aumento no interesse sobre o parasito (TRAVERSA e GUGLIELMINI, 2008).…”

“…A doença é cosmopolita e, embora a infecção seja bastante comum, a maior parte dos gatos permanece assintomática (TAYLOR et al,2010;EHLERS et al, 2013). O parasito necessita de HI para que ocorra a infecção, e em estudo recente, a barata doméstica (Periplaneta americana) representa um potencial transmissor que não deve ser negligenciado pois está presente em todos os lugares do mundo (TRAVERSA et al, 2008;FALSONE, 2017;GIANNELLI et al, 2017;PENAGOS-TABARES et al, 2018). São poucos os relatos detalhados no Brasil.…”

“…Em Porto Alegre, de 88 gatos atendidos no Hospital de Clínicas Veterinárias da Universidade Federal do Rio Grande do Sul, foi encontrada uma prevalência de L1 de 29,5% (24/88), desses, 45% (24/88) foi identificado em 2008 e 5% (2/40) em 2009, o diagnóstico foi realizado pelo método de Baermann (EHLERS et al, 2013). A técnica de sedimentação por Baermann é o método coprológico utilizado para isolar larvas de primeiro estádio (L1) de nematódeos pulmonares a partir de amostras fecais, sendo atualmente o método de eleição para o diagnóstico de A. abstrusus (HENDRIX;ROBINSON, 2011;PENAGOS-TABARES et al, 2018).…”
