Hunting for answers: Assessing Brucella spp. seroprevalence and risks in red de...
Pires, Humberto; Cardoso, Luís; Lopes, Ana Patrícia; Fontes, Maria da Conceição; Silva, Sérgio Santos; Matos, Manuela; Pintado, Cristina SantosBetween 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-...
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.
Tuberculosis: integrated studies for a complex disease 2050
Rezaei, Nima; Hosseini, Nastaran-Sadat; Saghazadeh, Amene; Fateh, Abolfazl; Duse, Adriano; Ahmad, Aijaz; Braley, Alexander E.; Tahta, AlicanTuberculosis (TB) has been a disease for centuries with various challenges [1]. Like other places where challenges and opportunities come together, TB challenges were the inspiration for the scientific community to mobilize different groups for the purpose of interest. For example, with the emergence of drug resistance, there has been a huge volume of research on the discovery of new medicines and drug delivery...
Animal tuberculosis: gross lesions and anatomopathological diagnosis
Quintas, Helder; Prada, Justina; Fontes, Maria da Conceição; Coelho, Ana Cláudia; Pires, IsabelAnimal tuberculosis (TB) is a zoonotic disease with worldwide distribution that can cause serious animal infections with economic and public health concerns. In its turn, human TB is currently one of the leading causes of death in the world due to a curable disease. Although the diagnosis demands microbiological culture confirmation, anatomopathological diagnosis of suggestive lesions often provides a presumpti...

Seropositivity for Coxiella burnetii in wild boar (Sus scrofa) and red deer (Ce...
Pires, Humberto; Cardoso, Luís; Lopes, Ana Patrícia; Fontes, Maria da Conceição; Matos, Manuela; Pintado, Cristina Santos; Figueira, LuísQ 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, Humberto; Cardoso, Luís; Lopes, Ana Patrícia; Fontes, Maria da Conceição; Silva, Sérgio Santos; Matos, Manuela; Pintado, Cristina SantosHepatitis 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...

Seroprevalence of West Nile Virus in vultures in the Centre region of Portugal
Loureiro, Filipa; Sargo, R.; Sousa, L.; Silva D.; Silva, F.; Lopes, F.; Peñuela, R.; Azorín, B.; Pires, Humberto; Cardoso, Luis; Lopes, Ana PatríciaWest 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, ...
