Abstract
Animal models of diabetes, such as db/db mice, are a useful tool for deciphering the genetic background of molecular changes at the initial stages of disease development. Our goal was to find early transcriptomic changes in three tissues involved in metabolism regulation in db/db mice: adipose tissue, muscle tissue and liver tissue. Nine animals (three per time point) were studied. Tissues were collected at 8, 12 and 16 weeks of age. Transcriptome-wide analysis was performed using mRNA-seq. Libraries were sequenced on NextSeq (Illumina). Differential expression (DE) analysis was performed with edgeR. The analysis of the gene expression profile shared by all three tissues revealed eight upregulated genes (Irf7, Sp100, Neb, Stat2, Oas2, Rtp4, H2-T24 and Oasl2) as early as between 8 and 12 weeks of age. The most pronounced differences were found in liver tissue: nine DE genes between 8 and 12 weeks of age (Irf7, Ly6a, Ly6g6d, H2-Dma, Pld4, Ly86, Fcer1g, Ly6e and Idi1) and five between 12 and 16 weeks of age (Irf7, Plac8, Ifi44, Xaf1 and Ly6a) (adj. p-value < 0.05). The mitochondrial transcriptomic profile also changed with time: we found two downregulated genes in mice between 8 and 12 weeks old (Ckmt2 and Cox6a2) and five DE genes between 12 and 16 weeks of age (Mavs, Tomm40L, Mtfp1, Ckmt2 and Cox6a2). The KEGG pathway analysis showed significant enrichment in pathways related to the autoimmune response and cytosolic DNA sensing. Our results suggest an important involvement of the immunological response, mainly cytosolic nucleic acid sensing, and mitochondrial signalling in the early stages of diabetes and obesity.

Abstract
Coagulase-positive staphylococci (CoPS) are opportunistic veterinary pathogens, of which Staphylococcus aureus, S. delphini and S. intermedius can be isolated from pigeons. The biochemical identification of S. delphini and S. intermedius isolates may be incorrect, because of their phenotypic similarity. The purpose of the present study was to isolate and identify CoPS from domestic and feral pigeons and to determine their genetic relatedness by PFGE. A total number of 31 isolates of CoPS were obtained, 15 were identified as S. delphini group B, six as S. aureus, four as S. delphini group A, three as S. intermedius and three as S. schleiferi subsp. coagulans. The results indicate that S. delphini group B is the predominant CoPS species among pigeons studied. PFGE restriction patterns of S. delphini group A and S. delphini group B form separate clusters, demonstrating their genetic heterogeneity. Indistinguishable or very similar PFGE patterns observed among S. delphini group B isolates from domestic and feral pigeons confirm the possibility of CoPS transmission between these birds.

Abstract
The aim of the study was to determine whether the four-month experimental therapy of mycobacteriosis in budgerigars may cause a complete recovery. A group of nine budgerigars was infected with a Mycobacterium avium subsp. avium isolate with proven pathogenicity for budgerigars. Five weeks post-inoculation, multidrug therapy was started. Another group comprising six birds received the same treatment but no infection, and the third group also comprising six birds was kept without infection or treatment as a control. The adopted antibiotic regimen included clarithromycin 61 mg/kg b.w., moxifloxacin 25 mg/kg b.w. and ethambutol 60 mg/kg b.w. administered by crop gavage every 12 h for 18 weeks. Despite a significant improvement in the condition of the infected, treated birds, the four-month therapy was not sufficient for the complete recovery of all.
