Due to the importance of the disease caused by Toxoplasma gondii, knowing its distribution in wild animals is essential to understand the transmission cycle of the protozoan. Therefore, the objective of the study was to report the molecular identification of T. gondii DNA in a sample of cardiac muscle tissue from C. thous in southern Brazil. For this purpose, a specimen of C. thous, found dead after being run over, was collected on the highways of Cerrito, Rio Grande do Sul, Brazil and sent to the laboratory for necropsy. Tissue fragments (spleen, liver, kidney, heart, lung, lymph nodes, bone marrow and blood) were collected and its genomic DNA was extracted. The samples were subjected to polymerase chain reaction (PCR) amplification using the 18S rRNA gene, and T. gondii DNA was amplified in cardiac muscle samples. The presence of the protozoan was confirmed by genetic sequencing. This study reports the molecular detection of T. gondii DNA in cardiac muscle of C. thous in southern Brazil, demonstrating the presence of the protozoan in the studied region. In addition, a new molecular sequence is being provided, contributing to the knowledge and epidemiology of the parasite.","PeriodicalId":72458,"journal":{"name":"Brazilian journal of veterinary medicine","volume":"47 ","pages":"e000725"},"PeriodicalIF":0.0,"publicationDate":"2025-06-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12186458/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144487356","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}

Currently, there is no highly effective treatment available, and many animals that exhibit symptoms ultimately die as a result of the disease and its complications. The clinical signs of leishmaniasis are varied and nonspecific. The main symptoms are severe anemia and thrombocytopenia, weight loss, splenomegaly, lymphadenomegaly, liver disease, kidney failure, and skin lesions, among others. Due to the chronic inflammatory state caused by the parasite, an oxidative environment is created, leading to potential cell injury and damage to the infected animals' genetic material. To investigate DNA damage, we conducted the micronucleus test and comet assay, as well as measured serum LDH levels in infected and non-infected dogs. Our results indicate that infected dogs present significantly higher levels of serum LDH (461.4 ± 204.5 U/L, n=36) compared to healthy dogs (142.38 ± 37.94 U/L, n=5). Additionally, the DNA of infected dogs is more damaged than that of the control group, as demonstrated by the micronucleus test (p=0.01) and comet assay (p=0.002). These findings suggest that Leishmania infantum infection can lead to clastogenic events, highlighting the need for further research on this process. It is important to consider the potential mutagenic properties of Leishmania infantum, given its ability to cause DNA damage in infected animals.","PeriodicalId":72458,"journal":{"name":"Brazilian journal of veterinary medicine","volume":"47 ","pages":"e001425"},"PeriodicalIF":0.0,"publicationDate":"2025-06-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12186459/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144487355","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 research was based on a questionnaire completed by 220 horse owners in the State of Rio Grande do Norte, Brazil. The data collected covered aspects including antibiotic use, prescription sources, the performance of culture and susceptibility tests, and the disposal of veterinary drug waste. The results indicated that 98.63% of horse owners administered antibiotics mainly to treat respiratory diseases. However, adherence to veterinary prescriptions was limited, with only 47.72% of horse owners correctly following the guidelines regarding dosage and treatment duration. Additionally, 68.18% of horse owners did not perform culture tests prior to antimicrobial treatment, and many obtained antibiotic recommendations from non-professional sources, such as friends or staff at veterinary product stores. These findings suggest that inappropriate antibiotic use practices, such as empirical and non-prescribed use, are contributing to the rise in antimicrobial resistance. The need for educational campaigns targeting horse owners is critical to raise awareness about the importance of rational antimicrobial use, risks of indiscriminate use, and necessity of performing laboratory tests to select appropriate treatment options.","PeriodicalId":72458,"journal":{"name":"Brazilian journal of veterinary medicine","volume":"47 ","pages":"e000425"},"PeriodicalIF":0.0,"publicationDate":"2025-05-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12124762/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144200874","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 goal was to analyze the most frequent pathologies, as well as assess the sexes, ages, and breeds of the patients, with an emphasis on the perinatal population. Out of 945 clinical histories, 776 pertained to perinatology. Survival rates were calculated, and a descriptive analysis was performed. The overall survival rate for neonates was 73.6%, with females constituting 57% of the neonatal patients. The most prevalent breed among mares and neonates was the Creole Colombian Horse. Neonatal maladjustment accounted for 39.34% of the neonatal cases, and regarding the affected systems, there was a common multisystemic presentation (71.40%). Of the 341 foals admitted for neonatal adaptation, 72 were clones (with a survival rate of 76.39%), while 269 were non-clones (with a survival rate of 72.49%). A total of 202 mares (88.98%) were hospitalized for pregnancy monitoring, while 25 mares (11.02%) were brought to the perinatology center to treat dystocia or other reproductive pathologies. The most frequent diagnosis among mares was placentitis (73.68%). This study noted an increase in survival rates over time, which was associated with improvements in protocols and the acquisition of new medical equipment. The survival rates observed in this study are consistent with those reported in previous research. The collected data indicate that foaling occurs year-round in Colombia since the country experiences no distinct seasons. Studies with larger sample sizes are suggested, as well as periodical analysis of casuistry in the equine neonatology field, to improve the clinical management of patients and enhance productivity in the horse breeding industry.","PeriodicalId":72458,"journal":{"name":"Brazilian journal of veterinary medicine","volume":"47 ","pages":"e005824"},"PeriodicalIF":0.0,"publicationDate":"2025-05-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12124761/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144200875","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 study's objective of this study was to evaluate lacrimal and nasolacrimal system findings in dogs treated byat an ophthalmology service, determine the frequency of lacrimal and nasolacrimal system disorders, and correlate the diagnosed changes with the patient's main complaint. All dogs underwent a complete ophthalmic examination, emphasizing the lacrimal and nasolacrimal tests: the Schirmer tear test, tear film break-up test, tear crystallization test, and Jones test. The findings of these tests correlated with those of the ocular surface and the general condition of the dogs. Statistical analyses were performed using the Shapiro-Wilk test, Pearson's chi-square test, and Student's t test. The Student's t test revealed that dogs with normal tear crystallization test scores had a significantly higher score (25.5 ± 4.94) than dogs with altered tear crystallization test scores (15.35 ± 6.64) (t (40) = 2.121, p = 0.004).

This retrospective study used data from the lameness examination, evaluated using an objective assessment with body-mounted wireless inertial sensors. The lameness examination comprised clinical history, static inspection, palpation, gait evaluation (for which the animals were equipped with a wireless inertial sensor system), flexion tests, lunging examination, diagnostic anesthetic blocks, and imaging examinations. Based on objective assessment data, the condition of lameness, limb with primary lameness, type of lameness, intensity, and location of lameness were determined. Of the 235 animals included in this study, 93,6% presented lameness. Of the animals with lameness, 59,5% had forelimb lameness and 40,5% had hindlimb lameness. The most frequent lameness condition was primary lameness in one limb and secondary lameness in the other. Impact lameness was the most frequent type in both the forelimb and hindlimb. Moderate-to-severe lameness was the most frequent level of intensity. Regarding the lameness location, in the forelimb, the distal region was the most affected, while in the hindlimb, the proximal lower region was the most affected.
