- Brucella spp. seroprevalence in wild ungulates in PortugalPublication . Pires, Humberto; Matos, Manuela; Cardoso, Luis; Lopes, Ana Patrícia; Fontes, Maria da Conceição; Santos Pintado, Cristina Maria Baptista; Figueira, Luís Manuel Faria; Mesquita, João R.; Matos, Ana; Coelho, Ana CláudiaBrucella spp. seroprevalence in wild ungulates in Portugal.
- Histopathological findings and molecular diagnosis of Nocardia spp. in wild mammalsPublication . Matos, Manuela; João, S.; Matos, Ana; Figueira, Luís Manuel Faria; Cardoso, Luis; Coelho, Ana Cláudia; Pinto, Maria de LurdesNocardiosis is an emerging zoonosis caused by Nocardia spp. bacteria. The disease is linked to infections in immunocompromised individuals, being potentially lethal when it turns systemic. The development of reliable and valid diagnostic methods is crucial to the identification of these pathogenic agents, particularly in wild mammals, which are potential reservoirs in the wildlife. A convenience sample of 114 wild mammals belonging to the orders Canidae, Cervidae, Erinaceidae, Herpestidae, Mustelidae, Suidae, and Viverridae were studied.
- Occurrence of Coxiella burnetii in red deer (Cervus elaphus) in PortugalPublication . Pires, Humberto; Cardoso, Luis; Lopes, Ana Patrícia; Fontes, Maria da Conceição; Matos, Manuela; Santos Pintado, Cristina Maria Baptista; Figueira, Luís Manuel Faria; Mesquita, João R.; Matos, Ana; Coelho, Ana CláudiaOccurrence of Coxiella burnetii in red deer (Cervus elaphus) in Portugal.
- A preliminar study on Brucella spp. seroprevalence in wild boar (Sus scrofa) in PortugalPublication . Pires, Humberto; Matos, Manuela; Cardoso, Luis; Lopes, Ana Patrícia; Fontes, Maria da Conceição; Pintado, Cristina; Santos Pintado, Cristina Maria Baptista; Figueira, Luis; Figueira, Luís Manuel Faria; Mesquita, João R.; Matos, Ana Cristina; Matos, Ana; Coelho, Ana CláudiaVarious species of the genus Brucella are highly virulent zoonotic agents. Brucella melitensis, B. abortus, and B. suis area broadly spread worldwide and animal brucellosis has a significant economic impact. This zoonotic disease affects both domestic pigs and wild pigs such as wild boar (Sus scrofa) In order to investigate the importance of wild boar (Sus scrofa) in the epidemiology of Brucella infection in Portugal, a serological survey was performed on samples from 184 wild boar fron the Centre region of Portugal.
- Serological evidence of Coxiella burnetii exposure in hunting dogs in Portugal.Publication . Pires, Humberto; Cardoso, Luis; Lopes, Ana Patrícia; Fontes, Maria da Conceição; Matos, Manuela; Santos Pintado, Cristina Maria Baptista; Figueira, Luís Manuel Faria; Mesquita, João R.; Matos, Ana; Coelho, Ana CláudiaCoxiella burnetii is a γ-Proteobacteria that is the etiologic agent of Q fever, a worldwide zoonosis. The role of dogs in the transmission of C. burnetii to humans is uncertain, and extensive seroprevalence studies of dogs have previously not been conducted in Portugal. A serologic survey was conducted for antibodies to C. burnetii in a sample of 90 hunting dogs from east-central Portugal, namely the municipalities of Proença-a-Nova and Castelo Branco, during the hunting season of 2021.
- Serological evidence of West Nile Virus infection in horses from the municipality of Castelo BrancoPublication . Loureiro, Filipa; Pires, Humberto; Cardoso, Luis; Lopes, Ana Patrícia; Fontes, Maria da Conceição; Santos Pintado, Cristina Maria Baptista; Figueira, Luís Manuel Faria; Matos, Manuela; Coelho, Ana Cláudia; Matos, AnaWest Nile Virus (WNV) is an RNA virus from the family Flaviviridae. It is transmitted by several genera of mosquitoes, with Cullex spp. as the main vectors identified in Europe and North America. Birds are amplifying agents and important to the transmission cycle, during the viremia period. Equines are considered dead-ends hosts and are recognized as sentinels of the virus in many countries.
- A serological survey of Brucella spp. in red deer (Cervus elaphus) in PortugalPublication . Pires, Humberto; Matos, Manuela; Cardoso, Luis; Lopes, Ana Patrícia; Fontes, Maria da Conceição; Santos Pintado, Cristina Maria Baptista; Figueira, Luís Manuel Faria; Mesquita, João R.; Matos, Ana; Coelho, Ana CláudiaWildlife has been identified as important sentinels for the surveillance of zoonotic pathogens such Brucella infection. Systematic brucellosis monitoring in wildlife is not demanded by regulatory acts, but several studies have reported the presence of this infection in European countries. In order to investigate the importance of red deer (Cervus elaphus) in the epidemiology of Brucella infection in Portugal, a serological survey was performed on samples of 276 hunted red deer from the centre of Portugal.
- Seroprevalence of Hepatitis E Virus in wild boar (Sus scrofa) and in red deer (Cervus elaphus) in PortugalPublication . Pires, Humberto; Cardoso, Luis; Lopes, Ana Patrícia; Fontes, Maria da Conceição; Matos, Manuela; Pintado, Cristina; Figueira, Luís Manuel Faria; Matos, Ana; Coelho, Ana Cláudia; Mesquita, João R.Hepatitis E virus (HEV) is recognized as a zoonotic agent causing an emerging human viral disease in industrialized nations. HEV is primarily found in domestic pigs and wild boars, which serve as the primary animal host for the virus globally, but also camels and deers, which serve as reservoirs. In order to investigate the importance of the wild red deer (Cervus elaphus) and wild boar (Sus scrofa) in the epidemiology of HEV infection, a serological survey was performed on samples from 648 wild ungulates (297 wild red deer and 351 wild boar from the Center region of Portugal.
- Seroprevalence of West Nile Virus in vultures in the Centre region of PortugalPublication . Loureiro, Filipa; Sargo, R.; Sousa, L.; Silva D.; Silva, F.; Lopes, F.; Peñuela, R.; Azorín, B.; Pires, Humberto; Cardoso, Luis; Lopes, Ana Patrícia; Fontes, Maria da Conceição; Santos Pintado, Cristina Maria Baptista; Figueira, Luís Manuel Faria; Matos, Manuela; Matos, Ana; Coelho, Ana CláudiaWest Nile Virus (WNV) is a vector-borne pathogen with zoonotic potential widely spread throughout the world. The transmission cycle is maintained by mosquitoes (mainly Culex spp.) and wild birds. Human, equines and other mammals are incidental hosts, whichare unable to amplify the agent in their blood circulation. Two lineages has been identified as disease-causing in humans and other animals: WNV-1 and WNV-2, being the latter more common in Europe.
