Environment and Offspring Surveillance in Porcine Brucellosis

Investigación publicada en Frontiers in veterinary science

Porcine brucellosis, caused by Brucella suis (B. suis), is a notifiable disease causing significant economic losses in production systems. Most infected pigs may act as carriers and shed B. suis even if asymptomatic. This can contribute to environmental persistence, thus hindering control efforts. Here, the environment and the offspring were investigated during and after a B. suis outbreak at a sow breeding farm. The diagnosis of B. suis in sows (n = 1,140) was performed by culture and polymerase chain reaction (PCR) from vaginal swabs, indirect enzyme-linked immunosorbent assay (I-ELISA) from… Leer más

Bacteremia and Aortic Valvular Endocarditis in a Eurasian Stone-Curlew (Burhinus oedicnemus distinctus) Due to Streptococcus dysgalactiae

Artículo de investigación publicado en Journal of Wildlife Diseases

Burhinus oedicnemus distinctus is an endemic subspecies of Eurasian Stone-curlew present in the Canary Islands. Their populations are rapidly declining, mainly because of anthropogenic impacts. This report describes valvular endocarditis and septicemia in a Eurasian Stone-Curlew with left foot loss and severe contralateral bumblefoot… Leer más

Feline Gastrointestinal Eosinophilic Sclerosing Fibroplasia-Extracellular Matrix Proteins and TGF-β1 Immunoexpression

Veterinary sciences publica este artículo de investigación

Feline gastrointestinal eosinophilic sclerosing fibroplasia (FGESF) has been described as an inflammatory disorder with an eosinophilic component with etiopathogenesis that is still unknown. Sixteen intestinal samples from two veterinary diagnostic services (2014–2017) were included in the study. A histopathological criterion classified the cases into three grades (mild, moderate, and severe) according to the distribution of the lesions and the course. An immunohistochemical study of collagen I, collagen III, fibronectin, and transforming growth factor β1 (TGF-β1) was performed in ea… Leer más

Molecular detection of Tritrichomonas foetus in bovine samples: a novel real-time polymerase chain reaction (PCR) assay targeting EF1-alpha-Tf1 and a comparative study of published PCR techniques

Parasitology Research publica este artículo de investigación

The parasite T. foetus causes trichomonosis in cattle but is generally asymptomatic in males. Thus, many bulls carrying the disease go unnoticed, making the detection of T. foetus in bulls an important aspect for its control. Due to drawbacks posed by its cultivation, PCR is a preferred option for diagnostic laboratories. Most published PCR protocols target the genomic region compring the 18S, 5.8S, and 28S rRNA genes and internal transcribed spacers 1 and 2 (rRNA-ITS region), homologous to that of other Tritrichomonas species. There is minimal information on alternative genetic targets and no… Leer más

Permeability of artificial barriers (fences) for wild boar Sus scrofa in Mediterranean mixed landscapes

Artículo de investigación publicado en Pest management science

Background: Fences are one of the most widespread manmade features in nature, constituting an artificial limitation to the movement of wildlife. To date, their effects on wildlife behaviour have been understudied but this knowledge is required to design effective management procedures. Using 21 GPS-monitored wild boar, we evaluated the permeability of different types of fences and described temporal patterns and spatial hotspots for crossing events. A fence`s permeability was inferred by the crossing success, i.e., the number of times that animals crossed a barrier vs the number of times they … Leer más

Factors affecting the performance of P22 ELISA for the diagnosis of caprine tuberculosis in milk samples

Artículo de investigación publicado en Research in Veterinary Science

Caprine tuberculosis (TB) is a zoonosis caused by members of the Mycobacterium tuberculosis complex (MTBC). Caprine TB eradication programmes are based mainly on intradermal tuberculin tests and slaughterhouse surveillance. However, the use of serological test has been extended as a potential diagnostic tool in goats through the use of serum, plasma, or even milk samples. Milk production and the antibodies (Ab) present in milk can vary depending on several circumstances. In the present study, different factors that may affect the performance of humoral TB diagnosis were analysed using goat mil… Leer más
