Silver nanoparticles (AgNPs) have attracted significant interest in veterinary medicine due to their unique properties, including enhanced stability, greater antimicrobial efficacy, and reduced toxicity compared to traditional silver salts. Their applications span various areas of veterinary practice, such as dermatology, wound management, infection prevention, drug delivery, and disinfection. This review explores their use in pigs, highlighting their role as feed additives to prevent diarrhoea, as antibacterial agents in semen extenders, and veterinary dermatology. AgNPs possess broad-spectrum antibacterial activity against both Gram-positive and...

This study aimed to assess the toxicity of the anthelmintic drug praziquantel in the early life stages of grass carp (Ctenopharyngodon idella). The toxicity was evaluated based on mortality, early ontogeny development, growth, oxidative stress biomarkers, antioxidant enzymes and histopathology. Praziquantel at all tested concentrations (1, 2, 4 and 6 mg/l) showed no significant adverse effects on the hatching of grass carp. Concentrations of 2, 4 and 6 mg/l praziquantel caused significantly (P < 0.01) higher mortality and slower growth compared with controls. Praziquantel at concentrations (4 and 6 mg/l) showed a significant...

The decline in the bee colony strength due to high levels of Varroa destructor infestations necessitates the development of new control methods. This study evaluates the effectiveness of glycerin-oxalic acid strips and essential oils in managing Varroa destructor. The experiment was conducted in 2022 at the experimental apiary in Debelec, part of the Institute of Animal Husbandry in Kostinbrod. Six experimental groups, each treated with a different preparation, were compared to a control group of untreated colonies. Treatments included Beevital Hiveclean (20 ml per colony), Varro Red (2 ml per frame), ammonium nitrate strips (1.3 mm),...

A 6-year-old female neutered Turkish Angora cat was referred due to tachypnoea. The patient was diagnosed with cardiomegaly at a local hospital during a health screening two years ago. Tachypnoea occurred one year ago. On physical examination, the patient presented with a respiratory rate of 72 breaths per minute and a systolic blood pressure of 70 mmHg. Thoracic radiographs revealed severe cardiomegaly, left atrium (LA) enlargement, right atrium (RA) enlargement, right ventricular enlargement, and dilation of pulmonary arteries and veins. An alveolar pattern was identified in the right and left cranial lung lobes. Echocardiography revealed a membrane...
