BackgroundObesity is one of the most prevalent health problems in the canine population. While haemostatic parameters and markers of endothelial function have been evaluated in various disease conditions in dogs, there are no studies of these markers in canine obesity. This study was designed to evaluate the effect of naturally gained weight excess and obesity on inflammatory, hemostatic and endothelial biomarkers in dogs. A total of 37 overweight and obese dogs were compared with 28 normal weight dogs.ResultsOverweight and obese dogs had significantly elevated concentrations of serum interleukin-6 (IL-6) and C-reactive protein (hsCRP). Number of platelets, activity of factor X and factor VII were significantly higher, while activated partial thromboplastine time (aPTT) and soluble plasminogen activator receptor (suPAR) were significantly decreased. Statistical analysis of high mobility group box – 1 protein (HMGB-1), soluble intercellular adhesive molecule -1 (sICAM-1) and plasminogen activator inhibitor type 1 (PAI-1) concentrations did not show significant differences between the total overweight and obese group and the normal weight group of dogs.ConclusionsAnalytical changes in the dogs in our study reflects that weight excess in dogs can be associated with a chronic low degree of inflammation and a hypercoagulable state, where primary and secondary hemostasis are both affected. However obesity is not associated with impairment of endothelial function in dogs.
This study investigated the frequency of third-generation cephalosporin resistance in Klebsiella spp. isolated from animals in Croatia and the presence of blaCTX-M genes. A total of 711 enteric bacteria were isolated from clinical samples, and Klebsiella spp. isolates accounted for 6.9% (n = 49). Thirteen Klebsiella isolates (26.5%) were ESBL producers, nine isolates from the Klebsiella pneumoniae species complex (69.2%), and four (30.8%) Klebsiella oxytoca isolates. All carried the blaCTX-M-15 gene, and antimicrobial susceptibility testing revealed them as multidrug resistant. All were resistant to all tested cephalosporins, fluoroquinolones, aminoglycosides and aztreonam, 92.3% showed resistance to tetracycline, 84.6% to trimethoprim-sulfamethoxazole and 69.2% to nitrofurantoin. No isolate showed resistance to imipenem and meropenem. It can be concluded that ESBL-producing Klebsiella expressing the blaCTX-M gene are not rare among Klebsiella isolates from animals in Croatia.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
