The potential role of scavenging flies as mechanical vectors of Lagovirus europ...
Lopes, Ana M.; Almeida, Tereza; Diz, Sílvia; Côrte-Real, João V.; Osório, Hugo; Ramilo, David W.; Rebelo, Maria Teresa; Pereira da Fonseca, IsabelThe European rabbit (Oryctolagus cuniculus) populations of the Iberian Peninsula have been severely affected by the emergence of the rabbit haemorrhagic disease virus (RHDV) Lagovirus europaeus/GI.2 (RHDV2/b). Bushflies and blowflies (Muscidae and Calliphoridae families, respectively) are important RHDV vectors in Oceania, but their epidemiological role is unknown in the native range of the European rabbit. In ...
Zoonotic visceral leishmaniasis : new insights on innate immune response by blo...
Rodrigues, Armanda Viana; Valerio-Bolas, Ana; Alexandre-Pires, Graça; Aires Pereira, Maria; Nunes, Telmo; Ligeiro, Dario; Pereira da Fonseca, IsabelL. infantum is the aetiological agent of zoonotic visceral leishmaniasis (ZVL), a disease that affects humans and dogs. Leishmania parasites are well adapted to aggressive conditions inside the phagolysosome and can control the immune activation of macrophages (MØs). Although MØs are highly active phagocytic cells with the capacity to destroy pathogens, they additionally comprise the host cells for Leishmania i...
Dogs with leishmaniosis: how are we managing proteinuria in daily practice? A P...
Monteiro, Marta; Prata, Sara; Cardoso, Luís; Pereira da Fonseca, Isabel; Leal, RodolfoABSTRACT Background: Proteinuria is a common fnding in dogs with leishmaniosis. Although antileishmanial therapeutic protocols are widely implemented, little information is available on which treatments are most adequate for identifying proteinuria in patients with canine leishmaniosis (CanL), especially regarding the use of immunosuppressants. The aim of this study was to explore the current paradigm regarding...
Molecular survey of vector-borne diseases in two groups of domestic dogs from L...
Dordio, Ana Mafalda; Beck, Relja; Nunes, Telmo; Pereira da Fonseca, Isabel; Gomes, JacintoABSTRACT - Background: Canine vector-borne diseases (CVBDs) are caused by a wide range of pathogens transmitted by arthropods. They have been an issue of growing importance in recent years; however, there is limited information about the vector-borne pathogens circulating in Portugal. The aim of the present study was to detect canine vector-borne bacteria and protozoa of veterinary and zoonotic importance using...
Louse flies in Azorean and mainland populations of four Passeriformes species_a...
Tomás, André; Pereira da Fonseca, Isabel; Valkenburg, Thijs; Rebelo, Maria TeresaHippoboscid flies, also known as louse flies, are obligate blood-feeders ectoparasites of birds and mammals. By studying louse fly parasites of four Passeriformes species, Eurasian blackbird (Turdus merula), Eurasian blackcap (Sylvia atricapilla), common chaffinch (Fringilla coelebs) and European robin (Erithacus rubecula), with dissimilar time of colonization of Azores islands, we tested whether: (i) island ho...
Presence of one ecto- and two endoparasite species of the black stork (Ciconia ...
Ramilo, David; Caetano, Inês; Brazio, Erica; Mira, Manuela; Antunes, Leonor; Pereira da Fonseca, Isabel; Cardoso, LuísBackgroundThe black stork (Ciconia nigra Linnaeus, 1758) is a recognized endangered species in Europe and most of the specimens from the Western Palearctic region breed in the Iberian Peninsula. Available works regarding parasites in black storks are scarce. This work reports the presence one ecto- and two endoparasite species from a black stork in Portugal.Case presentationA black stork was found in southern P...
Diagnosis and clinical management of canine leishmaniosis by general veterinary...
Monteiro, Marta; Prata, Sara; Cardoso, Luís; Pereira da Fonseca, Isabel; Leal, RodolfoBackground: Canine leishmaniosis (CanL) can be appropriately managed following international recommendations. However, few studies have assessed the preferred protocols in real-life veterinary practice and whether these are in line with the guidelines. This survey aimed to investigate the current trends in the clinical management of CanL among veterinary practitioners in Portugal, taking into consideration dife...
Culicoides spp. found near Lusitano stud farms in mainland Portugal which may c...
Pessoa, V.; Ramilo, David W.; Pereira da Fonseca, Isabel; Ferreira, Manuel Branco; Marti, Eliane Isabelle; Tilley, PaulaInsect Bite Hypersensitivity (IBH) is a common cutaneous disease, affecting a large number of horses worldwide. Several studies have identified Culicoides spp. saliva as a clinically relevant allergen source. The prevalence of IBH in Portugal, particularly in Lusitano horses, is still not known. However, the environmental characteristics of the national territory are favorable to the activity of Culicoides, and...
Meglumine antimoniate and miltefosine combined with allopurinol sustain pro-inf...
Santos, Marcos André Ferreira; Alexandre-Pires, Graça; Pereira, Maria A.; Marques, Cátia Filipa Saraiva; Gomes, Joana; Correia, Jorge Manuel de JesusCanine leishmaniosis (CanL) caused by Leishmania infantum is a zoonotic disease of global concern. Antileishmanial drug therapies commonly used to treat sick dogs improve their clinical condition, although when discontinued relapses can occur. Thus, the current study aims to evaluate the effect of CanL treatments in peripheral blood, lymph node, and bone marrow cytokine profile associated with clinical recovery...
Coccidian parasites from birds at rehabilitation centers in Portugal, with note...
Cardozo, Sergian Vianna; Berto, Bruno Pereira; Caetano, Inês; Thomas, André; Santos, Marcos; Pereira da Fonseca, Isabel; Gomes Lopes, Carlos WilsonABSTRACT - Portugal has some rehabilitation centers for wild animals, which are responsible for the rehabilitation and reintroduction of birds, among other animals, into the wild. Coccidian parasites of these wild birds in rehabilitation centers are especially important because these centers can introduce coccidian species into new environments through the reintroduction of their respective hosts. In this conte...
