Caracterização de ácaros trombiculídeos em cães e gatos de Portugal e pesquisa ...
Marques, Cátia; Delgado, Inês; Cruz, João T.; Costa, Pedro; Portela, Gonçalo André de Oliveira; Munhoz, Ana; Waap, Helga; Pereira, AndréOs ácaros trombiculídeos são ectoparasitas com potencial zoonótico, responsáveis por sinais clínicos dermatológicos e neurológicos em cães, gatos e humanos. Para além do seu potencial zoonótico, os trombiculídeos podem ser vetores de vários agentes patogénicos, tratando-se de um problema de saúde pública. Os Médicos Veterinários geralmente não detetam a presença destes parasitas nos animais domésticos e, quando...
Ácaros trombiculídeos: revisão de uma parasitose negligenciada em animais de co...
Marques, Cátia; Delgado, I.; Cruz, J.; Costa, P.; Portela, G.; Munhoz, Ana; Waap, Helga; Pereira, A.; Ramilo, DavidA trombiculose é uma parasitose causada por ácaros trombiculídeos (Acari: Trombiculidae) que afeta vertebrados, incluindo cães, gatos e o ser humano. É a fase larvar dos ácaros trombiculídeos que se caracteriza por ser parasita obrigatório e responsável pelo aparecimento de sinais clínicos. Estes incluem prurido, várias lesões cutâneas, podendo, em alguns casos, surgir distúrbios gastrointestinais, neurológicos...
Assessing the failure in transfer of passive immunity in beef calves: two case ...
Silva, Carolina Balao; Costa, Lina; Santos, Rute; Pereira, Luisa; Pinto, Henrique; Waap, HelgaIntroduction: Failure in Transfer of Passive Immunity (FTPI) is a condition that occurs frequently in the bovine species when inadequate ingestion or absorption of enough good-quality colostrum takes place. In bovine kept in extensive conditions, FTPI diagnosis is usually made by complete physical examination, with not enough time for laboratory analysis, and treatment is based on the administration of colostru...

Survey on the prevalence of Dermanyssus gallinae in commercial laying farms in ...
Waap, Helga; Nunes, Telmo; Mul, M. F.; Gomes, Jacinto; Bartley, KathrynDermanyssus gallinae, also known as the poultry red mite (PRM), is a blood-feeding ectoparasite of poultry and sylvatic birds. This mite is endemic in many parts of the globe and poses a threat to the egg industry, while compromising the health and welfare of hens, both directly and as a vector of diseases. In addition, people attacked by D. gallinae may develop gamasoidosis. Despite the high prevalence in seve...
Isolation and molecular characterization of Toxoplasma gondii isolated from pig...
Vilares, Anabela; Gargaté, Maria João; Ferreira, Idalina; Martins, Susana; Júlio, Cláudia; Waap, Helga; Ângelo, Helena; Gomes, João PauloCats and pigeons are important factors in the epidemiology of Toxoplasma gondii as felids are the only definitive hosts that can excrete environmentally resistant oocysts, and pigeons share the same places of cats and humans constituting a good model and indicator of the ground field contamination. We aimed to study the virulence and genotypes of T. gondii isolated from pigeons and stray cats in Lisbon, Portuga...
In vitro isolation and seroprevalence of Toxoplasma gondii in stray cats and pi...
Waap, Helga; Cardoso, R.; Leitão, A.; Nunes, T.; Vilares, Anabela; Gargaté, Maria João; Meireles, José; Cortes, Hélder; Ângelo, HelenaOral contamination with Toxoplasma gondii oocysts shed by cats into the environment has been linked to severe outbreaks of human toxoplasmosis. Pigeons (Columba livia) are highly susceptible to oral infection with oocysts and indirectly indicate soil contamination, since they feed from the ground. A seroprevalence study was performed on cats and pigeons captured in the city of Lisbon. Serum samples collected fr...

Epidemiological and genetic characterization of Toxoplasma gondii in urban pige...
Waap, Helga; Vilares, Anabela; Rebelo, Eugénia; Gomes, Salomé; Ângelo, HelenaCircumstantial evidence suggests that birds may be a good indicator of soil contamination, since they feed from the ground. Therefore a study was conducted to assess the prevalence of Toxoplasma gondii in urban pigeons (Columba livia) from different areas of the city of Lisbon and to genetically characterize T. gondii strains isolated from infected animals, in order to assess circulating genotypes. Sera from 69...
