“…Initial inflammatory responses occur in the walls of the pulmonary vasculature and are critical for pathogenesis and further development of the disease ( 2 ). This chronic and progressive infection may have a fatal outcome for definitive hosts and clinical cardiopulmonary disease has been reported in several carnivores, including domestic and wild canids [e.g., foxes, wolves ( 3 )] and felids. Feline infections are increasingly reported from areas endemic for canine dirofilariosis, but generally show a low parasite burden and asymptomatic infections.…”

Dirofilaria immitis Microfilariae and Third-Stage Larvae Induce Canine NETosis Resulting in Different Types of Neutrophil Extracellular Traps

et al. 2018

Heartworm disease is a zoonotic vector-borne disease caused by Dirofilaria immitis mainly affecting canids. Infectious third-stage larvae (L3) are transmitted to the definitive hosts via culicid mosquitoes; adult nematodes reside in the pulmonary arteries and in the right heart releasing unsheathed first-stage larvae (microfilariae) into the bloodstream leading to chronic and sometimes fatal disease. So far, early innate immune reactions triggered by these different D. immitis stages in the canine host have scarcely been investigated. Therefore, D. immitis microfilariae and L3 were analyzed for their capacity to induce neutrophil extracellular traps (NETs) in canine polymorphonuclear neutrophils (PMN). Overall, scanning electron microscopy analysis revealed both larval stages as strong inducers of canine NETosis. Co-localization of PMN-derived extracellular DNA with granulocytic histones, neutrophil elastase, or myeloperoxidase in parasite-entrapping structures confirmed the classical characteristics of NETosis. Quantitative analyses showed that both larval stages triggered canine NETs in a time-dependent but dose-independent manner. Moreover, parasite-induced NET formation was not influenced by the parasites viability since heat-inactivated microfilariae and L3 also induced NETs. In addition, parasite/PMN confrontation promoted significant entrapment but not killing of microfilariae and L3. Both, NETosis and larval entrapment was significantly reversed via DNase I treatments while treatments with the NADPH oxidase inhibitor diphenyleneiodonium failed to significantly influence these reactions. Interestingly, different types of NETs were induced by microfilariae and L3 since microfilarial stages merely induced spread and diffuse NETs while the larger L3 additionally triggered aggregated NET formation.

An extensive literature review is made of the parasites in marine and freshwater fish in mainland Portugal, the Portuguese archipelagos of the Azores and Madeira, as well as in farmed fish. The host(s) of each parasite species, its location in the host, site of capture of the host, whenever possible, and all the available bibliographic references are described. The economic importance of some parasites and the zoonotic relevance of some parasitic forms are discussed. A general overview of the data is provided, and some research lines are suggested in order to increase and complement the current body of knowledge about the parasites of fish from Portugal.Keywords: Parasites, fish, pathology, economy, zoonotic diseases, Portugal. ResumoÉ feita uma revisão do conhecimento dos parasitas de peixes de Portugal com base em extensa compilação bibliográfica. São referidos os parasitas de peixes marinhos e de água doce do continente, dos Arquipélagos da Madeira e dos Açores, bem como os parasitas de peixes de piscicultura. Para cada espécie é indicado o hospedeiro, localização no hospedeiro, local de pesca quando possível, e referências bibliográficas disponíveis. Discute-se a importância econômica de alguns dos parasitas e a relevância zoonótica de algumas formas. É feita uma avaliação geral dos dados e sugerem-se linhas de pesquisa que aumentem e complementem o conhecimento atual sobre os parasitas de peixes de Portugal.

“…The majority of the cestodes infecting deep-water fishes appear to be larval stages belonging to the order Tetraphyllidea, and adults of the order Trypanorhyncha. Larval trypanorynchs were also found in some deep-water sharks [18,40,47,48]. Acanthocephala are poorly represented in the deep-water habitat, with only 3 species found to date [7,17,49].…”

“…Larval stages of cestodes, of the orders Trypanorhyncha and Tetraphyllidae, were transmitted to the black scabbard fish, by feeding on cephalopods and crustaceans, as well as on mesopelagic fishes [6,17]. In the deep water realm trypanorhynchs of the families Aporhynchidae, Gilquinidae and larval tetraphyllideans are the most common cestodes infecting fishes and sharks [18,40,47,48]. Nevertheless, trypanorhynchs of the families Tentaculariidae and Sphyriocephalidae, common parasites of epipelagic and mesopelagic fishes, were additionally found in the black-scabbard fish and the conger eel [9,17,54].…”

The deep-water fish fauna of Macaronesian islands is currently estimated at a total of 1029 different fish species, but records of both ecto- and endoparasites are from only about 30 of those species. This fact presents an exciting field of research for scientists interested in fish parasitology, by exploring the structure of parasite communities and their connections with ecological and oceanographic variables. Research on the effect of climatic changes on the parasite faunas, on the occurrence of fish parasites in man and its impact on human health, has not been carried out to date. The present review aims to collate our present knowledge about the parasites of deep-water fishes of Macaronesia, and to suggest directions for future research on the parasites of fishes from the deepwater realm. A checklist of the parasites infecting the deep-water fishes from this region is included.
