RESUMEN
Surgical site infections (SSIs) cause significant complications in the postoperative period in veterinary surgeries. Determining the aetiology of infections is crucial for increasing treatment success rates. This study aims to assess treatment processes by identifying the bacterial agents responsible for infections occurring in cats and dogs after orthopaedic operations and to determine the antimicrobial resistance profiles of these agents. Strains isolated from SSIs were retrospectively analysed in patients brought to the Surgical Clinic of Siirt University Animal Health Application and Research Hospital between 2021 and 2023. The isolates were identified using MALDI-TOF MS. The disc diffusion method was applied to determine the antimicrobial susceptibility of the isolates. A high isolation rate was detected in methicillin-resistant Staphylococcus pseudintermedius and extended-spectrum beta-lactamase (ESBL) producing Enterobacteriaceae. According to the antimicrobial susceptibility results, cephalosporin treatment was continued in only one of the cases in which prophylactic treatment with cephalosporin group antibiotics was applied. Consequently, this study revealed that preoperative prophylactic antibiotic administration may not be sufficient in preventing surgical site infections. Diagnosis of aetiological agents and evaluation of antimicrobial susceptibility are essential in preventing surgical site infections and determining effective treatment options.
RESUMEN
Increased risk of pancreatic cancer may be associated with consumption of sugar containing foods. The aim of this study was to evaluate the effect of peach nectar containing high fructose corn sirup (HFCS) consumption in a pancreatic carcinogenesis rat model induced by 7,12-Dimethyl benzanthracene (DMBA). Fifty-day-old male Sprague Dawley rats were fed with peach nectar containing HFCS + chow, peach nectar containing sucrose + chow and only chow. After 8 mo, feeding period, each group was divided into two subgroups, in which the rats were implanted with DMBA and no DMBA (sham). Histologic specimens were evaluated according to the routine tissue processing protocol. The animals with ad libitum access to pn-HFCS, pn-sucrose and chow (only) showed significant differences in chow consumption and glucose level. Necropsy and histopathologic findings showed tumor formation in the entire group treated with DMBA. Excluding one rat in chow group, which was classified as poorly differentiated type, the others were classified as moderately differentiated pancreatic ductal adenocarcinoma (PDAC). This study demonstrated that daily intake of HFCS did not increase body weight and there was no effect of peach nectar consumption on the development of PDAC induced by DMBA in rats.
