The present study aimed to compare the impact of different anesthetic techniques on the electrocardiogram of hedgehogs. The animals were given three different anesthetic combinations: ketamine + xylazine, ketamine + diazepam, and ketamine + midazolam. The study measured the heart rate, duration, and amplitude of the P wave, QRS complex, and T wave through bipolar II derivations. Normal sinus rhythm was observed following induction by all anaesthetic combinations; however, the combination of ketamine and xylazine resulted in a significant decrease in heart rate. The P wave was positive with different combinations of anesthetics. The mean amplitude of the P wave in hedgehogs anesthetized using ketamine+xylazine was significantly lower than when using ketamine+diazepam and ketamine+midazolam. The QRS polarity was positive in leads I, II, and aVF after anesthesia induced by all combinations. The duration and amplitude of the QRS complexes did not differ significantly between all combinations. Hedgehogs anesthetized with ketamine+midazolam revealed the highest amplitude of the QRS (0.23 mv), while in the ketamine+diazepam anesthetized group, lowest amplitude (0.18 mv) was observed. The T wave was positive in all leads except leads III and aVR. Animals anesthetized with ketamine + xylazine had the lowest amplitude (0.117 mv) and the longest duration (0.08 s) of the T waves. The findings suggest that ketamine+midazolam is the choice combination based on ECG evaluation in hedgehogs.</div></div>","PeriodicalId":37152,"journal":{"name":"Veterinary and Animal Science","volume":"26 ","pages":"Article 100400"},"PeriodicalIF":1.9,"publicationDate":"2024-10-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142533493","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The treatment of <em>Malassezia</em> infections is based on the local application of antifungals often combined with antiseptics. Due to increased resistance of yeast to commonly used antimycotics, especially in biofilm-forming cells, the use of natural substances, e.g. plant essential oils, appears as a new promised option. In this study, the efficacy of selected plant essential oils (EO) – oregano, rosemary, bergamot, clove, cinnamon, and thyme – in combination with chlorhexidine on both planktonic and biofilm-forming cells of <em>M. pachydermatis</em>, was investigated. The checkerboard test was used to determine the effect of chlorhexidine combined with individual EOs. According to the FICI (fractional inhibitory concentration index) in planktonic cells, most combinations showed additive effect, except for thyme and rosemary EO, where a synergistic effect was found (33.3 % and 16.7 % respectively). In the biofilm-forming cells, a synergistic effect was noted in chlorhexidine combined with bergamot EO, recorded in 6 isolates (33.3 %), and with thyme and oregano EO, detected in 3 isolates (16.7 %). A significant decrease (<em>p</em> ˂ 0.05) was found in FIC (fractional inhibitory concentration) compared to MIC (minimum inhibitory concentration), for both planktonic and biofilm-forming cells.

Given this background, this study aimed to identify mammal species occurring near laying-hen houses and characterize the spatiotemporal patterns of these visits. Seven camera traps were deployed for a year-long period in three commercial poultry farms in a densely populated poultry area in Northern Italy. Various methods, including time series analysis and generalized linear models, were employed to analyze daily mammal visits.

For wild mammals, visits significantly increased at night, and slightly decreased during the spring season. Overall, the data hereby provided lay the groundwork for designing novel surveillance and intervention strategies to prevent cross-species disease transmission.
