This study aimed to determine the distribution of coagulase-positive staphylococci causing clinical skin and ear infections in dogs and to determine methicillin-resistant isolates. A total of 78 staphylococcal strains were isolated from clinical samples taken from patients at the Dermatology Clinic at the Faculty of Veterinary Medicine in Belgrade, Serbia. Multiplex PCR was used for species-specific identification, and <jats:italic>mecA</jats:italic> and <jats:italic>mecC</jats:italic> genes were used to determine methicillin resistance, in addition to phenotypic determination, MIC values and detection of PBP2a. Out of the 78 samples analyzed, 65.8% were identified as <jats:italic>Staphylococcus pseudintermedius</jats:italic>, 22.4% as <jats:italic>S. aureus</jats:italic>, 7.9% as <jats:italic>S. coagulans</jats:italic>, and 3.9% as <jats:italic>S. intermedius</jats:italic>. Four <jats:italic>S. aureus</jats:italic> isolates exhibited methicillin resistance confirmed by cefoxitin disk diffusion, while five were confirmed with MIC testing and latex agglutination. <jats:italic>MecA</jats:italic> gene was detected in 29.4% of <jats:italic>S. aureus</jats:italic> and 30% of <jats:italic>S. pseudintermedius</jats:italic> isolates. These isolates were classified as methicillin-resistant <jats:italic>S. aureus</jats:italic> (MRSA) and methicillin-resistant <jats:italic>S. pseudintermedius</jats:italic> (MRSP), respectively. No isolates carried the <jats:italic>mecC</jats:italic> gene. This study provides insights into the prevalence of CoPS species and methicillin resistance in isolates from dogs.

A total of 94 blood sera were analyzed, 33 from rams and 61 from ewes. The results showed 23 (69.7%) positive findings in rams and 2 (3.3%) positive findings in ewes, with an overall prevalence of 25.4% bounded by a 95% confidence interval.

The results indicate a slightly higher sensitivity of Real time PCR compared to conventional PCR in diagnosing <jats:italic>B. ovis</jats:italic> from the reproductive tissues of rams. However, the differences in sensitivity between different nucleic acid extraction protocols were not significant. Most rams showed a positive PCR result in only one sample of reproductive tissue, suggesting the recommendation to take multiple samples from each animal.

However, the limited availability of fresh platelets in veterinary medicine due to the challenging storage requirements poses a significant constraint. Lyophilized platelets offer extended shelf-life and convenient storage options, enhancing their accessibility for thrombocytopenic patients. However, only a limited number of studies have examined the clearance and survival rate of transfused lyophilized platelets, particularly regarding the lyophilization technique utilizing trehalose as a platelet stabilization agent. The objective of this study was to assess the recovery and survival rate of trehalose lyophilized platelets within the circulatory system. To investigate these parameters, CMFDA-labeled lyophilized platelets were administered to mice, and their recovery and survival rates were analyzed. Flow cytometric analysis revealed the rapid clearance of lyophilized platelets from the systemic circulation. The immediate post-infusion percent recovery of labeled platelet particles was 42.7 ± 8.15 %. The average survival rates at post-infusion time points at 15, 30, 45, and 60 minutes were 28.2 ± 4.31, 14.5 ± 3.56, 5.1 ± 2.02, and 0.82 ± 0.57, respectively. The calculated mean half-life was 8.39 ± 0.44 minutes. The most pronounced decrease in labeled lyophilized platelet count occurred during the 30-minute timeframe immediately following infusion. Subsequently, over 99% of lyophilized platelets were eliminated after 60 minutes post-infusion. These findings indicate that higher dosages and more frequent administration of trehalose lyophilized platelets might be necessary to achieve a therapeutic effect comparable to that of fresh platelets.","PeriodicalId":7379,"journal":{"name":"Acta Veterinaria","volume":"20 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-12-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"138682793","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

An increase in reactive oxygen species (ROS) concentration and the occurrence of oxidative stress can lead to changes in the structure of proteins, lipids, and DNA. The level of oxidative stress can be determined by measuring the end products of lipid peroxidation known as reactive substances of thiobarbituric acid (TBARS) of which malondialdehyde (MDA) is the most important. The concentration of MDA can be easily measured in various tissues and body excretions, but also by a non-invasive method of hair sampling. In this research, we have collected dog hair in grooming saloons, fluorometrically measured TBARS levels and compared the obtained values with factors such as breed, sex, age, passive smoking, sterilization, and season. No significant difference between sterilized and non-sterilized dogs was observed.

The investigated parameters were quantified using spectrophotometric method for determination of enzyme activities and MDA concentration in the blood. We found that treatment with linden honey in the socially isolated animals significantly increased the enzyme activities of CAT and GPx, and significantly decreased the concentration of MDA. The modulation of CAT and GPx activities in socially isolated animals treated with linden honey may be very important for understanding the role of honey in the capacity of antioxidant defense system to increase and maintain its stability in psychosocial stress conditions.

In veterinary medicine, these changes are poorly understood. Therefore, this study was aimed at the analysis of the distribution of blood serum protein fractions separated by agarose gel electrophoresis, and at the determination of the concentrations of main acute phase proteins in bitches with mammary gland neoplasia. The evaluation was conducted on twelve female dogs with palpable single or multiple nodules in the parenchyma of the mammary gland and on ten tumor-free clinically healthy bitches to compare the possible differences in the obtained results. Blood serum was used to perform agarose gel electrophoresis of the main blood serum protein fractions and to analyze the concentrations of total serum proteins and the following canine acute phase proteins: serum amyloid A, haptoglobin, C-reactive protein and α<jats:sub>1</jats:sub>-acid glycoprotein. The concentrations of total serum proteins were slightly higher in bitches with mammary gland tumors. Serum protein electrophoresis showed lower mean concentrations of albumin and α<jats:sub>1</jats:sub>-globulins in the affected dogs, while the concentrations of α<jats:sub>2</jats:sub>-and β<jats:sub>1</jats:sub>-globulins were significantly higher (P=0.0032 and P=0.0021, respectively) compared to dogs without mammary gland tumors. In the concentrations of acute phase proteins, significantly higher mean concentrations of C-reactive protein and haptoglobin were obtained in dogs with mammary tumors (P=0.0025 and P=0.0002, respectively). The values of α<jats:sub>1</jats:sub>-acid glycoprotein did not vary markedly between the bitches with and without mammary tumors.
