Zoonotic Onchocerca lupi Infection in Dogs, Greece and Portugal, 2011–2012
Otranto, Domenico; Dantas-Torres, Filipe; Giannelli, Alessio; Latrofa, Maria Stefania; Papadopoulos, Elias; Cardoso, Luís; Cortes, HelderOnchocercosis by Onchocerca lupi is an emerging zoonosis, but only case reports are available in dog populations. Of 107 animals sampled in Greece and Portugal, 9 (8.4%) scored positive. Molecular analysis confirmed the morphological identification and showed that those from Portugal differed at larger extent from all others available.
First cross-sectional serological survey on Besnoitia besnoiti in cattle in Italy
Rinaldi, Laura; Maurelli, Maria Paola; Musella, Vincenzo; Bosco, Antonio; Cortes, Helder; Cringoli, GiuseppeA cross-sectional serological survey was conducted to evaluate the prevalence of besnoitiosis in cattle farms located in a region of southern Italy. A geographical information system (GIS) was used in order to uniformly sample the bovine farms (n = 88) throughout the entire region. Blood samples were collected from 528 autochthonous cattle and sera were tested for antibodies to Besnoitia besnoiti using an enzym...

Cortes, Helder Carola Espiguinha; Leitão, A.; Waap, H.; Vilares, A.; Ângelo, H.; Meireles, J.O isolamento de Toxoplasma gondii é imprescindível quer para efeitos de diagnóstico definitivo da infecção, quer para estudos visando a genotipagem de estirpes circulantes, tanto nos animais como no ser humano. O bioensaio é presentemente considerado o método de eleição para isolamento de T. gondii de amostras biológicas, no entanto, para além de eticamente questionável, a inoculação em ratinho é dispendiosa e ...
Besnoitia besnoiti protein disulfide isomerase (BbPDI): molecular characterizat...
Marcelino, Eduardo; Martins, Tiago M.; Morais, Joana B.; Nolasco, Sofia; Cortes, Helder; Hemphill, Andrew; Leitão, Alexandre; Novo, CarlosBesnoitia besnoiti is an apicomplexan parasite responsible for bovine besnoitiosis, a disease with a high prevalence in tropical and subtropical regions and re-emerging in Europe. Despite the great economical losses associated with besnoitiosis, this disease has been underestimated and poorly studied, and neither an effective therapy nor an efficacious vaccine is available. Protein disulfide isomerase (PDI) is ...
Ixodidae encontrados no Avestruz (Struthio camelus Linnaeus, 1766) em Portugal.
Cortes, Helder; Caeiro, V.Ostriches are acquiring a status of species for livestock production in Portugal. The introduction of this species can lead to new animal and public health problems. Ixodidae in two ostrich herds have been found following our veterinary parasitological activity. As ticks are vectors and agents of diseases, such as Crimean-Congo Haemorrhagic Fever (CCHF) we are compelled to keep epidemiological surveillance on t...
Jornadas de Actualização Diagnóstica em Dermatologia e Alergologia Veterinárias
Martins, Luís; Cortes, HelderNo âmbito do bem-estar animal, os animais de companhia vêm sendo, cada vez mais, sujeitos a observação clínica por patologias do foro imunoalergológico. Para além das manifestações digestivas e cutâneas decorrentes de alergia alimentar, é também frequente a dermatite pela picada de insectos, como as pulgas, um problema com elevada relevância clínica, e a rinoconjuntivite e dermatite invernal por sensibilização ...

Cortes, Helder C.E.; Reis, Yara; Gottstein, Bruno; Hemphill, Andrew; Leitão, Alexandre; Müller, NorbertBesnoitia besnoiti, an apicomplexan protozoan parasite, is the causative agent of bovine besnoitiosis. This infection may dramatically affect body condition, and, in males, lead to irreversible infertility. While identification of clinical cases and their histopathological confirmation is relatively simple to carry out, finding subclinical forms of infection is more difficult, thus a more sensitive test for the...

Cortes, Helder; Chagas e Silva, J.; Baptista, M.C.; Pereira, R.M.; Leitão, A.; Horta, A.E.M.; Vasques, M.I.; Barber, J.; Marques, C.C.Besnoitia besnoiti is a bovine parasite endemic in many tropical and subtropical areas whose prevalence in the Mediterranean countries such as Portugal seems to be increasing. Most infections are mild or subclinical, characterized by the formation of numerous cutaneous and sub-cutaneous microcysts, lowering the quality of skins for the leather industry. Male sterility or impaired fertility is a common sequela i...
