Genetic and virulence characterization of Toxoplasma gondii strains isolated f...
Vilares, Anabela; Gargate, M.J.; Ferreira, I.; Martins, S.; Waap, H.; Ângelo, H.habitat with cats and humans, bands are observed in recreational areas such as urban parks, playgrounds and parks. The interaction between cats, birds and human population is quite evident favoring the fecal-oral transmission of T. gondii between the definitive host and intermediate hosts, in the urban cycle of the parasite. The results of the inoculation in vivo of the brain homogenates showed pigeon isolation...
A modified agglutination test for the diagnosis of Besnoitia besnoiti infection
Waap, H; Cardoso, R; Marcelino, E; Malta, J; Cortes, H; Leitão, AAbstract Bovine besnoitiosis is caused by Besnoitia besnoiti, an obligate intracellular apicomplexan parasite. Affected animals present cutaneous and systemic manifestations and the disease may lead to considerable economic losses. Although generally associated to tropical and subtropical areas, bovine besnoitiosis is now considered an emergent disease in Europe, due to the increasing number of new cases and a...
Isolamento de Toxoplasma gondii a partir de cérebro e músculo de gatos serologi...
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 ...
Isolation of Besnoitia besnoiti from infected cattle in Portugal
Cortes, H.C.E.; Reis, Y.; Waap, H.; Vidal, R.; Soares, H.; Marques, I.; Pereira da Fonseca, I.; Fazendeiro, I.; Ferreira, M.L.; Caeiro, V.; Shkap, V.Abstract Besnoitia besnoiti, an obligate intracellular protozoan parasite belonging to the phylum apicomplexa, is the causative agent of bovine besnoitiosis. Besnoitiosis is responsible for significant losses in the cattle industry of Africa and Mediterranean countries due to the high morbidity rate, abortion and infertility in males. The acute stage of disease is associated with the proliferative forms (tachyz...
