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...
Smells Like Anthelmintic Resistance-Gastrointestinal Prevalence, Burden and Div...
Batista, CL; Cabeças, R; Araújo-Paredes, C; Pereira, MA; Mateus, TLAnthelmintic resistance has been documented worldwide, but few cases have been reported in dogs. Shelter dogs are a great opportunity to study intestinal helminths and assess their potential resistance to anthelmintic compounds. With these two goals in mind, 361 faecal samples were collected from dogs in 18 municipalities in Portugal, from 19 shelters and 11 private tutors. These samples were analysed using the...
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...
Innovative waste activated sludge pre-treatment using a raceway pond Reactor: I...
Monteiro, JP; Catarina Cruzeiro; Duarte, MS; Pereira, MA; Vitor VilarA novel pre-treatment, using a raceway pond reactor (RPR), combining the use of thermal and solar effects, was applied to enhance anaerobic digestion (AD) of waste activated sludge (WAS) from an urban wastewater treatment plant. Thermal pre-treatment at 25, 50, 60 and 70 degrees C was carried out for 5 h with (under distinct values of UV radiant power) and without solar radiation and varying WAS depth in the RP...
An Antibody-Based Survey of Toxoplasma gondii and Neospora caninum Infection in...
Pereira, MA; Nóbrega, C; Mateus, TL; Almeida, D; Oliveira, A; Coelho, C; Cruz, R; Oliveira, P; Faustino-Rocha, A; Pires, MJ; Mesquita, JR; Vala, HSimple Summary Toxoplasma 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 back...
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...
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...
Seroprevalence of SARS-CoV-2 in Client-Owned Cats from Portugal
Oliveira, A; Pereira, MA; Mateus, TL; Mesquita, JR; Vala, HThe close contact between humans and domestic cats raises concerns about the potential risks of SARS-CoV-2 transmission. Thus, this study aims to investigate anti-SARS-CoV-2 seroprevalence in client-owned cats from Portugal and evaluate the infection risk of cats that maintain contact with human COVID-19 cases. A total of 176 cats, belonging to 94 households, were sampled. Cat owners answered an online question...
Prevalence of Toxoplasma gondii Antibodies and Risk Factor Investigation in Por...
Almeida, D; Santos Silva, S; Pereira, MA; Santos, C; Mega, C; Coelho, C; Nobrega, C; Esteves, F; Cruz, R; Vala, H; Mesquita, JR(1) Background: Toxoplasma gondii is a widespread zoonotic agent that greatly impacts Public Health, being responsible for one of the most important parasitic zoonosis worldwide. T. gondii has a heteroxenous life cycle, with cats being the definitive hosts and all warm-blooded animals, including humans, being intermediate hosts. Veterinary practitioners (VP) may be at a higher risk than the general population f...
Occurrence and Distribution of Fasciolosis in a Cohort of Ovine Livestock Restr...
Coelho, C; Cruz, R; Esteves, F; Vala, H; Pereira, MA; Amorim, I; Nóbrega, C; Mesquita, JRFasciola hepatica is a parasite that is widespread in Europe, having been reported in ruminants of several European countries and causing an important economic impact. This study ascertained the occurrence and distribution of fasciolosis in Portuguese ovine livestock by assessing F. hepatica IgG antibodies in a cohort of confined sheep from a high-altitude region of central Portugal in a 2-year period. Positive...
