Natural infection of common cranes () with highly pathogenic avian influenza H5N1 in Serbia.

Introduction: The late autumn epizootic of the highly pathogenic avian influenza virus (HPAIV) subtype H5N1 in Serbia in 2023 caused massive mortality in the migratory population of common cranes (). This is the first time HPAIV has been identified in the common crane in Serbia, leading to mass mortality of this bird species.

Methods: To understand the pathological impact of HPAIV in cranes, we evaluated the pathological changes in the tissues of common cranes.

Genotyping of spp. in wild rats leads to first time detection of serovar Mozdok in Serbia.

Introduction: This study aimed to investigate the prevalence and molecular characterization of species in Belgrade, Serbia, an area where this disease is underexplored. Specifically, the study sought to employ molecular and multilocus sequence typing analyses to fill the gap in understanding the diversity and distribution of species within the region.

Methods: A comprehensive molecular analysis was conducted on kidney samples obtained from Norway rats () in the urban environment.

Multilocus sequence analysis (MLSA) of a Nocardia cyriacigeorgica strain causing severe bovine mastitis in Bosnia and Herzegovina.

Nocardia cyriacigeorgica is a well-known agent of human nocardiosis and is considered an emerging pathogen, however, its identification to the species level is complex for many clinical laboratories. Available data on the clinical significance of N. cyriacigeorgica in veterinary medicine are sparse and mainly concern isolated reports of pyogranulomatous lesions in domestic animals.

Macrophages, the main marker in biocompatibility evaluation of new hydrogels after subcutaneous implantation in rats.

Biocompatibility of materials is one of the most important conditions for their successful application in tissue regeneration and repair. Cell-surface interactions stimulate adhesion and activation of macrophages whose acquaintance can assist in designing novel biomaterials that promote favorable macrophage-biomaterial surface interactions for clinical application. This study is designed to determine the distribution and number of macrophages as a means of biocompatibility evaluation of two newly synthesized materials [silver/poly(vinyl alcohol) (Ag/PVA) and silver/poly(vinyl alcohol)/graphene (Ag/PVA/Gr) nanocomposite hydrogels] , with approval of the Ethics Committee of the Faculty of Veterinary Medicine, University of Belgrade.
