Racing pigeon competitions are a popular sport where success depends on birds’ ability to return fast to their loft of origin. However, many additional factors like differences in feeding, training, everyday care and even geographical loft location influence race outcomes, which has led to the development of the One Loft Race (OLR) system. The OLR system aims to eliminate these factors by housing pigeons from various lofts in equal conditions in one facility. This in turn, however, fosters inter-individual transmission of pathogens.

Piglets are vulnerable to stress during weaning because of changes in the feeding environment, nutrients, and other growth-impacting conditions. In this study, stress injury was modelled by continuous intraperitoneal injection of lipopolysaccharide (LPS) and was used to investigate the dynamics of antioxidant indices and immunoinflammatory factors in the piglet thymus.

Staphylococci are still a challenge in veterinary medicine, as they are one of the aetiological factors causing clinical and subclinical mastitis in small ruminants. The aim of the study was to analyse the occurrence of staphylococci in milk obtained from Świniarka (SW) and Uhruska (UHR) sheep and to characterise their drug resistance and virulence.

Periodontal diseases are the most frequently diagnosed problem in small animal veterinary medicine. Although their exact cause is not fully understood, bacteria play an important role in their development. Pseudomonas aeruginosa is a Gram-negative, rod-shaped, non-spore-forming bacterium. The living environment of this bacterium may be soil and water; however, it can also be found in humans and animals. Antibiotic treatment of periodontitis may be complicated by the carbapenem resistance of some P. aeruginosa strains, if these bacteria are found to be an aetiological agent. The aim of the study was to identify all bacterial strains isolated from dog with periodontitis.

The testicular-only processing fluid (TOPF) obtained from piglet testicles after castration could be an alternative sample for porcine reproductive and respiratory syndrome (PRRS) laboratory diagnosis. If this matrix were proved useful, testing it would spare piglets the stress of blood drawing and eliminate some labour required to take blood samples. The aim of the study was to evaluate the utility of TOPF for this diagnostic purpose.

This study aimed to investigate the impact of perinatal body condition score (BCS) and its subsequent loss on postpartum performance and health outcomes in dairy cattle.

The cellular and molecular pathways of α-lipoic acid’s (ALA’s) protective effect were assessed against diclofenac (DIC) hepatorenal injury in vivo and against a pro-inflammatory stimulus in vitro.

Lactococcus garvieae is a catalase-negative, Gram-positive coccus that occurs in pairs and short chains. It is present throughout the world and a causative agent of bovine mastitis. However, prior to writing, no case of mastitis caused by this bacterium had been reported in Poland. The aim of this research was to investigate the presence of L. garvieae in milk samples from Polish cows with inflammation of the mammary gland.

In Germany, around 150,000 kg of mostly Siberian sturgeon (Acipenser baerii), were produced in 2021. Sudden mortalities affected negative control Russian sturgeon in experimental infection of several European aquacultured fish species with tilapia lake virus (TiLV). An investigation sought the causative agent. In most of the sturgeon, a specific herpesvirus was detected which also occurred in the carp, crucian carp and tench subjects, but not in Nile tilapia. This herpesvirus was latent in the sturgeon population but became productive to cause the outbreak after three weeks of experimentation.

Fasciola hepatica is a trematode that infects ruminants worldwide. It is also the infectious agent of a zoonosis, fasciolosis, which is considered to be a re-emerging disease. There is no data about F. hepatica seroprevalence in European bison (Bison bonasus); however, complex population health monitoring is particularly important in protected species such as this. Addressing the need for this surveillance, the aim of this study was to assess for the first time the seroprevalence of F. hepatica in Polish free-living European bison populations and identify risk factors for infection.
