Molecular and serological screening support the lack of Coxiella burnetii circu...
Loureiro, Filipa; Mesquita, João R.; Cardoso, Luis; Pintado, Cristina Santos; Gonçalves, S. Gomes; Matos, Ana; Soeiro, V.; Gonçalves, A.; Silva, FilipeCoxiella burnetii is a highly infectious zoonotic pathogenic bacterium that has a major economic impact in the livestock industry throughout the world and causes unpredictable outbreaks in humans worldwide. Although it is known that birds are potential reservoirs of C. burnetii, their role in the epidemiological cycle of the pathogen has not been fully verified. Due to its non-specific symptoms and clinical sig...
Usutu virus in the Iberian peninsula: A systematic review
Loureiro, Filipa; Mesquita, João R.; Cardoso. Luis; Matos, Ana C.; Matos, Ana; Matos, Manuela; Coelho, Ana CláudiaStudies on Usutu virus (USUV) in Europe have been increasing through time, with USUV infection being identified in humans and animals. The emergence of USUV in Europe draws our attention to how an arbovirus is able to spread, adapt, and evolve in a unconventional environment. Understanding the epidemiological and evolutionary processes that contribute to the appearance, maintenance, and further spread of viral ...
Detection of Bagaza virus in Europe: A scoping review
Loureiro, Filipa; Mesquita, João R.; Cardoso, Luis; Matos, Ana; Matos, Manuela; Coelho, Ana CláudiaThe Bagaza virus (BAGV) belongs to the genus Orthoflavivirus (Ntaya serocomplex) and emerged in Europe, Spain, in 2010. The natural transmission cycle of this virus is perpetuated by Culex spp. mosquitoes and viraemic birds. The ability of BAGV to cause infection in several game birds from the family Phasianidae has been well-studied. BAGV is antigenically similar to other orthoflaviviruses from the Japanese en...
Update of canine morbillivirus infection in wild carnivores – a multicentric st...
Alves, Miguel; Ferreira, Mariana; Huck, S.; Lattier, M.; Charpin, A.; Wagnon, L.; Fekete, N.; Guglielminotti, M.-N.; Pinto, Maria de Lurdes; Matos, AnaCanine distemper is recognized as one of the most significant infectious diseases for wildlife across the to analyse canine distemper in wild carnivores within the European territory over the last five years (2018-2023). Cases were collected from three wildlife rescue centres from 3 countries: Wildlife Study and Rehabilitation Centre (CERAS), Quercus ANCN (Portugal), Wildlife Station Retscheider Hof e.V. (Germa...
Serological evidence of West Nile virus in wild birds in Portugal
Loureiro, Filipa; Matos, Ana; Santos Pintado, Cristina Maria Baptista; Cardoso, Luis; Silva, Filiipe; Matos, Manuela; Coelho, Ana CláudiaWest Nile Virus (WNV) has a zoonotic transmission cycle. Avian species are considered the definitive hosts, and mosquitoes and other arthropods are the main vectors. Humans are considered accidental and dead-end hosts, since mammals are unable to efficiently amplify the virus. We aimed at studying serological prevalence of WNV circulation in wild birds in Portugal.
Serological evidence of West Nile Virus infection in horses from the municipali...
Loureiro, Filipa; Pires, Humberto; Cardoso, Luis; Lopes, Ana Patrícia; Fontes, Maria da Conceição; Santos Pintado, Cristina Maria BaptistaWest 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.
Seroprevalence of West Nile virus antibodies in wild birds of prey in Portugal
Loureiro, Filipa; Cardoso, Luis; Matos, Ana; Matos, Manuela; Silva, Filipe; Coelho, Ana CláudiaWest Nile Virus is one of the most widely distributed arboviruses in the world with zoonotic potential. Seroepideiological studies are necessary to establish proper prevention and control strategies. WNV-total antibodies were searched in blood serum using an ELISA commercial kit. Samples from 136 individuals of diurnal raptors were analysed, from eight distinct Accipitriformes species. Eleven nocturnal birds of...
Seroprevalence of West Nile virus in Cinereous vultures (Aegypius monachus) and...
Loureiro, Filipa; Cardoso, Luis; Matos, Ana Cristina; Matos, Ana; Matos, Manuela; Silva, Filipe; Coelho, Ana CláudiaWest Nine virus (WNV) is an emergent zoonotic pathogen spread worldwide. This flavivirus is endemically maintained in a life cycle with birds acting as reservoirs, Culex mosquitopes as the main vectors, and human and horses as accidental dead-end hosts. The potential impact ofWNV infection on wildlife populations can be severe, especially in thjreatened or endangered species. This work might be useful as a star...
Evidence for sporadic Coxiella burnetii excretion in sheep milk, central Portugal
Pires, Humberto; Silva, S. Santos; Cruz, A.; Cardoso, Luís; Lopes, A.P.; Pereira, M.A.; Nóbrega, C.; Mega, A.C.; Santos, C.; Cruz, R.; Esteves, F.Coxiella burnetii, the causative agent of Q fever, is a globally distributed zoonosis, with cattle, sheep, and goats considered the main reservoirs of the disease (Agger et al,., 2013; Bento et al., 2023). Human transmission primarily occurs through inhaling infections aerosols from milk, faeces, urina, and birth products from infected ruminants. This study used a 2-year longitudinal approach to investigate C. ...
The complete mitochondrial genome of Potomida acarnanica (Kobelt, 1879)
Matos, Ana; Gomes-dos-Santos, André; Teixeira, Amílcar; Varandas, Simone; Sousa, Ronaldo; Karaouzas, Ioannis; Zogaris, Stamatis; Froufe, ElsaFreshwater mussels (Bivalvia, Unionida) play essential roles in the well-functioning of ecosystems, even providing essential services to humans. However, these bivalves face numerous threats (e.g. habitat loss and fragmentation, pollution, introduction of invasive species, and climate change) which have already led to the extinction of many populations. This underscores the need to fully characterize the biolog...
