Screening Wild Birds for Tick-Borne Zoonotic Pathogens in Portugal
Loureiro, F; Mesquita, JR; Cardoso, L; Santos-Silva, S; Moreira, G; Bento, JT; Soeiro, V; Gonçalves, A; Silva, F; Barradas, PF; Matos, AC; Matos, MWild birds may be involved in the transmission of agents of infectious diseases, including zoonoses, a circumstance which raises a number of public and animal health issues. Migratory bird species play a significant role in the introduction of tick-borne pathogens to new geographic areas, contributing to the dissemination of various etiological agents. This preliminary study aimed to assess the occurrence of fo...
Detection of Bagaza Virus in Europe: A Scoping Review
Loureiro, F; Mesquita, JR; Cardoso, L; Matos, AC; Matos, M; Coelho, ACThe 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...
Hunting for Answers: Assessing Brucella spp. Seroprevalence and Risks in Red De...
Pires, H; Cardoso, L; Lopes, AP; Fontes, MDC; Santos-Silva, S; Matos, M; Pintado, C; Roque, N; Fonseca, LF; Morgado, I; Dias, AS; Figueira, L; Matos, ACBetween 2016 and 2023, a cross-sectional study was conducted in the central region of Portugal in order to better understand the epidemiology and public health risks resulting from the handling and consumption of game animals infected with Brucella spp. The seroprevalence and risk factors for Brucella spp. seropositivity were evaluated. Antibodies against Brucella spp. were determined using a commercial enzyme-...
Molecular evidence of sporadic Coxiella burnetii excretion in sheep milk, centr...
Pires, H; Santos-Silva, S; Cruz, AVS; Cardoso, L; Lopes, AP; Pereira, MA; Nóbrega, C; Mega, AC; Santos, C; Cruz, R; Esteves, F; Vala, H; Matos, ACCoxiella burnetii is the etiologic agent of Q fever, a worldwide zoonosis. Cattle, sheep and goats are considered the main reservoirs of the disease. Transmission to humans occurs mainly through the inhalation of infectious aerosols from milk, faeces, urine, and birth products from infected ruminants. In this study, a 2-year longitudinal approach was performed to ascertain the excretion of C. burnetii in bulk t...
Serological evidence of antibodies to Flaviviridae in wild birds in Portugal
Loureiro, F; Cardoso, L; Matos, AC; Pintado, C; Silva, F; Ferreira, M; Brandão, R; Lopes, C; Lopes, AP; Mesquita, JR; Matos, M; Coelho, ACEmerging infectious diseases are a major threat to biodiversity and an important public health issue. Flaviviruses are the cause of several emerging vector-borne zoonotic arboviruses whose distribution is currently increasing in Europe. The evidence that West Nile virus (WNV) circulates in resident and migratory species has implications for both animal and public health and should therefore be studied in depth....
Seropositivity for Coxiella burnetii in Wild Boar (Sus scrofa) and Red Deer (Ce...
Pires, H; Cardoso, L; Lopes, AP; Fontes, MD; Matos, M; Pintado, C; Figueira, L; Mesquita, JR; Matos, AC; Coelho, ACQ fever is caused by the pathogen Coxiella burnetii and is a zoonosis that naturally infects goats, sheep, and cats, but can also infect humans, birds, reptiles, or arthropods. A survey was conducted for the detection of antibodies against C. burnetii in a sample of 617 free-ranging wild ruminants, 358 wild boar (Sus scrofa) and 259 red deer (Cervus elaphus), in east-central Portugal during the 2016-2022 huntin...
Prevalence and Risk Factors for Hepatitis E Virus in Wild Boar and Red Deer in ...
Pires, H; Cardoso, L; Lopes, AP; Fontes, MDC; Santos-Silva, S; Matos, M; Pintado, C; Figueira, L; Matos, AC; Mesquita, JR; Coelho, ACHepatitis E virus (HEV) is a zoonotic foodborne virus with an annual infection prevalence of 20 million human cases, which seriously affects public health and economic development in both developed and developing countries. To better understand the epidemiology of HEV in Central Portugal, a cross-sectional study was conducted from 2016 to 2023 with sera samples from wild ungulates. The seroprevalence and risk f...
Surgery of chest wall deformities
Matos, AC; Bernardo, JE; Fernandes, LE; Antunes, MJOBJECTIVE: To evaluate the medium-term results of 77 surgical corrections in patients with chest wall deformities, 53 (68.8%) with pectus excavatum and 24 with pectus carinatum, operated upon from 1985 to 1994. METHODS: The mean age of the patients was 14.7 years (4-39 years) and 77% were younger than 15 years of age. There were 59 male (76.7%) and 18 female patients. Only four had a family history of the malfo...
