It is becoming increasingly common for laboratories to allow the rehoming of dogs when they are no longer needed. There is no research, however, comparing the characteristics of dogs from laboratories to dogs acquired from more traditional sources for pets. This study used the Canine Behavioral Assessment and Research Questionnaire (C-BARQ) to compare emotional and behavioural characteristics of 100 former laboratory Beagles who were rehomed to a convenience sample of 244 pet Beagles with no known history of laboratory use. Our results revealed that the former laboratory Beagles exhibited increased fearfulness, attention and attachment behaviours,...

Pseudomonas aeruginosa is an infectious pathogenic bacteria infecting many different species of animals. Currently, it lacks a commercial vaccine. In this study, three monovalent DNA vaccines (poprL, poprF, and pflgE), three bivalent combination DNA vaccines (poprL+poprF, poprL+pflgE, poprF+pflgE), and a trivalent DNA vaccine (poprL+poprF+pflgE) were constructed. Consequently, we immunised chickens with these DNA vaccines and used inactivated vaccines as the positive controls. Then, the immune efficacy was evaluated through serum antibody detection, a lymphocyte proliferation assay, and cytokine concentration determination. Lastly, we assessed...

The study aimed to assess the effects of a therapeutic bath of five different antiparasitic drugs, in different baths and durations: fenbendazole (25 mg l-1, 12 h and 2 × 12 h), formaldehyde (0.17 ml l-1, 15 min), ivermectin (0.031 mg l-1, 1 h), mebendazole (1 mg l-1, 12 h) and levamisole (50 mg l-1, 2 h and 3 × 1 h) on the reduction on the intensity and prevalence of a monogenean infection (Dactylogyrus anchoratus) in juvenile carp. The best effect on reducing the parasite number was achieved with the bath in formaldehyde (0.17 ml l-1, 15 min) and fenbendazole (25 mg l-1,...

Measures for consumer protection against food adulteration and misleading labelling are integrated into EU legislation, including methods for detecting misleading practices. Verification of the meat content is available for marine products, but not for salmonid fish due to the lack of standard nitrogen factors. This study aimed to establish nitrogen factors for rainbow trout (Oncorhynchus mykiss) and brook trout (Salvelinus fontinalis). The study analysed 340 fish from Czech fisheries obtained in the summer of 2018-2020. According to the established ISO methods, fillet samples with and without skin were analysed for their nitrogen content...

Claviceps paspali is a fungus that mainly parasitises Paspalum dilatatum, generating a structure denominated sclerotium, in which indole-diterpenoid alkaloids are isolated. Its action mechanism is related to the inhibition of the gamma-aminobutyric acid receptor. It basically affects bovines, triggering the tremorgenic syndrome, the prevalence of this intoxication being relatively low in Europe. This work describes a clinical case on a cattle farm in Seville (southern Spain), composed of 91 bovines, 60% of which were principally affected with nervous clinical signs. The diagnosis was based on a clinical inspection of the animals, as well...

An 11-year-old spayed female Toy Poodle presented with acute tetraparesis. A small subcutaneous mass was found in the right trunk region, and the magnetic resonance revealed a compressive spinal cord lesion due to an irregular bone proliferation at the third cervical vertebra. After surgical resection of the vertebral lesion, the neurological symptoms improved, and the patient could walk on her own. The excised vertebral and subcutaneous masses were diagnosed as a mammary adenocarcinoma on the histopathological examination, with Ki-67 and HER-2 immunohistochemistry staining. This case report highlights the importance of defining the primary tumours...
