Renal biomarkers in companion animals - a review

Simple Summary: Recent advancements in molecular biology have identified potential biomarkers for diagnosing kidney diseases. They may improve the specificity and sensitiv- ity of diagnoses, allowing early detection and intervention. This review discusses studies on urine and blood biomarkers, highlighting their importance in various clinical settings. Ongoing research is necessary to integrate these biomarkers...

Screening Wild Birds for Tick-Borne Zoonotic Pathogens in Portugal

Wild 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

The 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...

Re: Development of unconventional treatments for mastitis in dairy cattle.

To the editor: We read the article entitled “Development of unconventional treatments for mastitis in dairy cattle” with great interest. Bovine mastitis is an inflammatory reaction of the udder tissue in the mammary gland initiated due to physical trauma or microorganism infections. As a direct effect of mastitis, there are significant economic losses due to decreased milk production and quality. It can also ca...

Hunting for Answers: Assessing Brucella spp. Seroprevalence and Risks in Red De...

Between 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...

Coxiella 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...

The first full study of heavy metal(loid)s in western-European hedgehogs (Erina...

The western-European hedgehog (Erinaceus europaeus) is an insectivore with a wide distribution in Portugal and a potential tool for biomonitoring relevant One Health hazards, including heavy metal(loid)s’ pollution. The aim of this study was to positively contribute to the current knowledge about the metal(loid) pollution in Portugal. Forty-six hedgehogs (from rescue centres; with known provenance) were necrops...

Serological evidence of antibodies to Flaviviridae in wild birds in Portugal

Emerging 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....

A Genotyping-by-Sequencing approach brings new insights into the population str...

Morphologic and Genetic Analysis of Synhimantus (Synhimantus) laticeps from a L...

The long-eared owl (Asio otus) is a medium-sized owl species that is well-distributed in almost all of the territories in Portugal. Nematodes were found in the oral cavity of a long-eared owl (A. otus) admitted to CRASSA (Wildlife Rehabilitation Centre of Santo Andre). During a physical exam and stabilization of the bird, five nematodes were collected. The worms were examined and measured under light microscopy...
