Relatório científico da Expedição Oceano Azul - Cascais | Mafra | Sintra
Cabral, H; Afonso, CML; Almada, F; Almeida, S; Alonso, H; Andrade, J; Anjos, M; Batista, M; Bentes, L; Carvalho, AC; Celestino, S; Coelho, PD; Coxey, MA zona marítima dos concelhos de Cascais, Mafra e Sintra tem sido pouco estudada, não obstante situar-se frente a grandes centros urbanos e ser alvo de diversos usos e atividades humanas. Algumas das suas características geográficas e dos seus elementos notáveis ao nível dos fundos marinhos acrescem o seu interesse científico e patrimonial. Com o objectivo de ampliar o conhecimento científico sobre a biodiversi...
An antibody-based survey of Toxoplasma gondii and Neospora caninum infection in...
Aires Pereira, M; Nóbrega, C; Mateus, TL; Almeida, D; Oliveira, A; Coelho, C; Cruz, R; Oliveira, PA; Faustino-Rocha, AI; Pires, MJ; Mesquita, JRToxoplasma gondii and Neospora caninum are intracellular parasites with a great impact on human and animal health, respectively. This work aims to investigate the presence of antibodies against T. gondii and N. caninum in client-owned cats from Portugal and to identify risk factors. A total of 183 domestic cats were sampled and their owners answered an online questionnaire designed to obtain background informat...
Pulmonary and Gastrointestinal Parasitic Infections in Small Ruminant Autochtho...
Pereira, MA; Vila-Viçosa, MJ; Coelho, C; Santos, C; Esteves, F; Cruz, R; Gomes, L; Henriques, D; Vala, H; Nóbrega, C; Mega, AC; Melo, C; Malva, MThe production of small ruminant autochthonous breeds in the Centre region of Portugal is practiced in a semi-extensive husbandry system, exposing animals to parasitic infections. The main objective of this study was to estimate the prevalence of lungworm infection and identify risk factors. Fecal samples of 203 goats and 208 sheep from 30 herds were collected per rectum and subjected to the modified Baermann t...
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...

Virtual physiology: a tool for the 21st Century
Nóbrega, C; Pereira, MA; Coelho C; Brás, C; Mega, AC; Santos, C; Esteves, F; Cruz, R; Faustino-Rocha, AI; Oliveira, PA; Mesquita, J; Vala, HVeterinary physiology is a basic curricular unit for every course within the veterinary field. It is mandatory to understand how the animal body works, and what to expect of a healthy body, in order to recognize any misfunction, and to be able to treat it. Classic physiology teaching involves wet labs, much equipment, many reagents, some animals, and a lot of time. But times are changing. In the 21st century, i...
Generalized Lymphadenopathy as the First Manifestation of Systemic Lupus Erythe...
Soares, L; Matos, A; Mello Vieira, M; Cruz, R; Caixas, ULymphadenopathy (LAP) is a common but nonspecific feature of many diseases, representing a vast spectrum of etiologies such as infectious or inflammatory diseases, malignancies, and drugs. In systemic lupus erythematosus (SLE), it can be the first manifestation. We present the case of a 20-year-old female with a history of fever, night sweats, anorexia, and asthenia for five months. She also had diffuse general...
Prevalence of Toxoplasma gondii Antibodies in Individuals Occupationally Expose...
Almeida, D; Quirino, J; Matos, P; Esteves, F; Cruz, R; Vala, H; Mesquita, JRToxoplasmosis is a worldwide zoonotic disease with different and complex routes for transmission. Workers occupationally exposed to animals or raw meat and viscera (WOE) may be at more risk than the general population, however conflicting data exist on the risk of developing toxoplasmosis due to this close contact. To add knowledge to this topic, the aim of the present study was to ascertain if WOE were more li...
A Questionnaire-Based Survey on the Long-Term Management of Canine Leishmaniosi...
Pereira, MA; Santos, R; Nóbrega, C; Mega, C; Cruz, R; Esteves, F; Santos, C; Coelho, C; Mesquita, JR; Vala, H; Santos-Gomes, GCanine Leishmaniosis (CanL) is a chronic and potentially fatal disease. In economically disadvantaged regions, costs associated with long-term patient monitoring may determine that some owners decline veterinary follow-up of their dogs. This online, questionnaire-based survey aimed to assess how Portuguese veterinary practitioners perform long-term patient monitoring and recognize relapses. More than 50% of res...
Rickettsia massiliae circulation in sheep and attached Rhipicephalus sanguineus...
Mesquita, JR; Santos-Silva, S; de Sousa Moreira, A; Baptista, MB; Cruz, R; Esteves, F; Vala, H; Barradas, PFRickettsiosis is considered an emerging/re-emerging vector-borne disease that causes significant public health threats. Ticks are reservoirs and vectors of Rickettsia having a significant role in the transmission of rickettsiae. In Portugal, little is known about tick-borne Rickettsia species in sheep. Therefore, this study aimed to investigate rickettsiae infection in ticks and their sheep host from 27 farms i...
