Seropositivity of Coxiella burnetii in wild boar (Sus scrofa) and red deer (Cervus elaphus) in Portugal

Coxiella burnetii is a zoonotic microorganism that infects a wide range of wild and domestic species, causing the disease Q fever, frequently involving ticks as vectors. To better understand the occurrence of C. burnetii infection in wild boar (Sus scrofa) and red deer (Cervus elaphus), an epidemiological study was conducted in the Centre region of Portugal.info:eu-repo/semantics/publishedVersio

Feline lungworm infection. An emerging concern?

Infectious feline upper respiratory tract disease is very common and Aelurostrongylus abstrusus is the most often diagnosed parasitic cause, although clinical signs may go unnoticed and diagnosis is challenging as it has several limitations. Noting that more cases have been recorded in recent years, the authors, in the present work, describe in detail the features of five cases of Aelurostrongylus abstrusus registered in their work and influence area, to alert animal health professionals to this emerging concern.info:eu-repo/semantics/publishedVersio

Canine hair follicular tumours: a retrospective study

Hair follicular tumours in dog comprise a large and heterogeneous group of neoplasms that display morphological features resembling one or several portions of the normal hair follicle which constitute a huge effort for its diagnosis. Histopathological evaluation is required to better characterize the different types of canine hair follicular tumours, in order to better understand its biological behaviour and to collaborate with the daily clinical practice. Thus, a retrospective, cross-sectional descriptive study was carried out with goal of analyse its frequency and characteristics, in order to contribute to a better understanding of this vast group of tumours. As main results the authors verified a higher incidence of follicular tumours in male dogs, being the most frequent types diagnosed trichoepithelioma, followed by, trichoblastoma, infundibular keratinizing acanthoma and pilomatricoma and the average age of dogs was 8.76 years. Also, malignant tumours represented 31.6% of all canine hair follicular tumours diagnosed (n= 114).info:eu-repo/semantics/publishedVersio

Cooling down the world oceans and the earth by enhancing the North Atlantic Ocean current

The world is going through intensive changes due to global warming. It is well known that the reduction in ice cover in the Arctic Ocean further contributes to increasing the atmospheric Arctic temperature due to the reduction of the albedo effect and increase in heat absorbed by the ocean’s surface. The Arctic ice cover also works like an insulation sheet, keeping the heat in the ocean from dissipating into the cold Arctic atmosphere. Increasing the salinity of the Arctic Ocean surface would allow the warmer and less salty North Atlantic Ocean current to flow on the surface of the Arctic Ocean considerably increasing the temperature of the Arctic atmosphere and release the ocean heat trapped under the ice. This paper argues that if the North Atlantic Ocean current could maintain the Arctic Ocean ice-free during the winter, the longwave radiation heat loss into space would be larger than the increase in heat absorption due to the albedo effect. This paper presents details of the fundamentals of the Arctic Ocean circulation and presents three possible approaches for increasing the salinity of the surface water of the Arctic Ocean. It then discusses that increasing the salinity of the Arctic Ocean would warm the atmosphere of the Arctic region, but cool down the oceans and possibly the Earth. However, it might take thousands of years for the effects of cooling the oceans to cool the global average atmospheric temperature
