Horses can contribute to the spread of bacterial diseases, which can be caused mainly by, Staphylococcus spp., which are part of the animals’ commensal microbiota, but it is also considered a pathogenic microorganism capable of causing serious infections. vancomycin, when it is resistant to methicillin. Antimicrobial resistance is considered a major health problem by the World Health Organization and the emergence of the mecA gene, responsible for resistance to the class of beta-lactam antibiotics. Thus, the aim of this work was to investigate the antimicrobial resistance profile and the presence of the mecA gene in Staphylococcus spp. isolated from the nasal, oral and auricular microbiota of horses used as animal traction on small family farms. Nasal, oral and auricular swabs were collected from 38 horses, with 29 (76.3%) isolated in nasal swab, 15 (39.4%) in auricular swab and 9 (23.6%) in oral swab, totaling 53 Staphylococcus spp. and 50 (94.33%) samples were resistant to the 11 antimicrobials tested, none of which were positive for molecular tests to identify the mecA gene. The results demonstrate the presence of Staphylococcus spp. associated with high (94.33%) bacterial resistance, indicating that horses can be considered reservoirs of multi-resistant microorganisms.

Pneumocephalus is a well described disease; it is commonly diagnosed in humans, but the condition is rarely encountered in veterinary medicine. Computed tomography (CT) is the gold-standard diagnostic method for identifying this disease, and other methods (such as necropsy) are rarely described. In this report, we describe necropsy findings of a 10-month-old, mixed-breed dog with intraventricular pneumocephalus. The dog was referred to Laboratory of Animal Pathology of the Federal University of Uberlândia, Brazil, for necropsy after being diagnosed with pneumocephalus upon CT. In the examination, the brain had dilation of both lateral ventricles with empty spaces. Histopathology showed congestion and mineralization only near the lateral ventricles, leading to the diagnosis of pneumocephalus based on the macroscopic findings. The animal also showed sinusitis characterized by nasal discharge and neutrophilic infiltration of nasal sinuses. However, bacterial culture was not conclusive because of contamination of the sample. This is therefore an important report that shows necropsy findings of intraventricular pneumocephalus, which is a rare condition in dogs. By documenting the necropsy findings, we hope to help veterinary pathologists, including those with limited access to diagnostic imaging.

Bovine tuberculosis (bTB) is a zoonosis caused by Mycobacterium bovis, a species belonging to the Mycobacterium tuberculosis complex (MTC) group. Direct bTB diagnosis from suggestive lesions can be performed by nested q-PCR targeting the Rv2807 gene present in the MTC group, as well as the TbD1 gene, present in M. bovis. In this context, the aim of the present study was to assess the importance of considering positive MTC results for the Rv2807 target gene obtained through the nested real time polymerase chain reaction (nested q-PCR) applied to samples obtained directly from suspected bTB lesions. A total of 174 samples of suggestive bTB caseous lesions were obtained during cattle slaughter in slaughterhouses in the state of Mato Grosso, Brazil. DNA was extracted from the lesions and nested q-PCR was performed to detect both MTC and M. bovis. Both samples positive for the Rv2807 (41/174) and TbD1 (29/174) were submitted to bacterial culturing (23/41), and the DNA of the isolates (23) was extracted and submitted again to nested q-PCR. The Rv2807 gene (MTC) was previously amplified by nested q-PCR directly from the lesions, although the TbD1 gene specific for M. bovis was not amplified previously in four of the successfully isolated samples (4/23), only following isolation, and only the Rv2807 gene was amplified before and after isolation. In conclusion, the target gene Rv2807(MTC) exhibited higher positivity in the analyzed samples compared to the TbD1 gene (M. bovis).

The present study aimed to evaluate the influence of local administration of gentamicin or cephalothin on the healing of surgical wounds in dogs. Thirty healthy dogs were submitted to surgical castration. They were divided into 2 groups of 15 animals. After the surgical procedure, two 0.6 cm circular cutaneous wounds were made in the abdominal region. Group 1 received 0.1 ml of 0.9% saline in one wound and 0.1 ml of gentamicin (40 mg / ml) in the other wound; and group 2 received 0.1 ml of 0.9% saline and 0.1 ml of cephalothin (200 mg / ml); respectively. All wounds were sutured and assessed macroscopically 1, 3 and 10 days after the operation. On day 10, an incisional biopsy was performed for histopathological evaluation. All analyzes of macroscopic variables did not show significant differences between groups (P <0.05). There were no significant differences between groups for microscopic evaluation of collagenization, vascularization, edema and inflammatory cells (P <0.05). Thus, the topical use of the tested antibiotics does not influence skin healing in dogs.

Ozone therapy application and research have increased recently. The mixture of oxygen-ozone (O2-O3) has been used as a therapeutic agent for the treatment of several diseases with beneficial effects. This brief literature review has the objective of disclosing the mechanisms of action and main clinical indications and possibilities of ozone therapy for different conditions. The local and systemic approaches and techniques described for human treatment can be easily transposed for use in animals, such as rectal insufflation; bag therapy; ozonated oil; intradiscal and paravertebral applications; in acupuncture points; minor autohemotherapy, and major autohemotherapy. The possibilities of clinical indications and dosages were also described, including immunological and infectious diseases. Although it is a minimally invasive and relatively safe approach, more clinical studies are necessary to standardize techniques, doses, and clinical indications.

Treatment of the bovine respiratory disease complex (BRDC) can elicit high bacterial resistance and stress to steers in a feedlot. Therefore, the present study aimed to evaluate three therapeutic protocols with long-acting antibiotics against BRDC naturally acquired in steers finished in feedlot. In a total of 80 animals finished in a feedlot, 18 steers showed clinical signs compatible with BRDC (mucopurulent nasal secretion, lung auscultation alteration, leukocytosis, and decrease of dry matter intake). These animals were randomly treated: marbofloxacin in a single dose (M1), marbofloxacin in two doses (M2), or ceftiofur in a single dose (C1) on Day 0. The clinical score of pneumonia, hemogram, daily food intake, and body weight were analyzed during 7 days. On slaughter day (Day 100), the body weight and frequency of lungs with pneumonia was evaluated. On Day 7, M2 showed absence of pneumonia, and M1 and C1 still showed a clinical score of mild pneumonia (P = 0.01). On day 2 and day 3 M2 showed a higher dry matter intake than others treatments (P = 0.05). C1 showed a lower body weight than others group on day 1 and 2 (P = 0.05). The C1 and M1 showed a higher pneumonia frequency than M2 (P = 0.02). The M2 slaughter weight was numerically higher than the other treatments. We conclude the marbofloxacin in two doses eliminated the pneumonia ́s clinical symptoms and allowed the animals to return the productivity earlier than other protocols.

This study aimed to evaluate the CD4+ and CD8+ T lymphocytes counts and CD4+: CD8+ ratio in a colony of cats with chronic gingivostomatitis (CGS). We used forty domestic short-haired cats inhabiting the same colony. Ten cats with CGS were immunodeficiency virus-positive (group IV), and ten with CGS were immunodeficiency virus-negative (group III). As a control, twenty cats without CGS were used: ten cats were immunodeficiency virus-positive (group II) and ten cats were immunodeficiency virus-negative (group I). We employed flow cytometry to count CD4+ and CD8+ T lymphocytes. In cats infected with the immunodeficiency virus, the presence of CD4+ lymphocytes were lower both for animals with and without CGS. Conversely, not immunodeficiency virus-infected cats with CGS had a higher amount of CD4+ when compared to seronegative animals without CGS. The counts of CD8+ T lymphocytes showed no significant difference among cats with CGS, whether infected with immunodeficiency virus or not. The CD4+: CD8+ ratio was only different for group III, which was higher than any other group. No difference was observed for total lymphocyte number and CD8+ among groups. By contrast, mean CD4+ levels were different, with cats from groups III and IV showing higher levels than those from groups I and II. The flow cytometry could be a useful tool for the diagnosis and prognosis of cats with CGS infected by the immunodeficiency virus.

Hyperadrenocorticism is a relatively common endocrine disease affecting the adrenal glands of domestic dogs. However, there are few reports of this disease in wild canids. A crab-eating fox (Cerdocyon thous) kept under human care was diagnosed with the disease after detection of conformational abnormalities in the adrenal glands visualized by ultrasonography, a cortisol suppression test after low-dose dexamethasone, and the detection of proteinuria and bacteria in urinalysis. After the diagnosis, the patient was treated with trilostane with a satisfactory clinical response. This report aims to report the sonographic and laboratory findings of hyperadrenocorticism and its treatment in a specimen of the species.

Metabolic syndrome, or metabolic dysfunction related to obesity in dogs, is a set of factors that may predispose comorbidities secondary to obesity. Adjuvant therapy with an energy-restricted diet, especially with low levels of carbohydrate and fat, is essential for weight loss, in addition to controlling snacks intake. The aim of this study was to evaluate the biochemical profile of obese dogs compared to lean dogs, and also to compare these profiles before and after a 30-day treatment, thus evaluating the possibility of obesity-related metabolic dysfunction and the action of adjuvant dietary therapy in this condition. Cholesterol and its fractions (HDL, LDL and VLDL), triglycerides, systemic blood pressure and glycemia of obese and lean dogs were measured, and seven obese dogs were treated only with a low-calorie diet with low levels of fat and carbohydrates for 30 days; these patients were evaluated before and after treatment. Obese dogs showed higher levels of triglycerides than lean dogs, and dogs treated with low-calorie diet presented weight loss and better outcomes related to biochemical profile, especially triglycerides levels, after treatment.

Cholesterol and its fractions (HDL, LDL and VLDL), triglycerides, systemic blood pressure and glycemia of obese and lean dogs were measured, and seven obese dogs were treated only with a low-calorie diet with low levels of fat and carbohydrates for 30 days; these patients were evaluated before and after treatment. Obese dogs showed higher levels of triglycerides than lean dogs, and dogs treated with low-calorie diet presented weight loss and better outcomes related to biochemical profile, especially triglycerides levels, after treatment.","PeriodicalId":38626,"journal":{"name":"Acta Veterinaria Brasilica","volume":"1 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-12-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"68197322","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}

The aim of the current report is to describe a cutaneous candidiasis case affecting a canine individual treated at the University Veterinary Hospital of State University of Maranhão (UEMA), in São Luís City. The patient had three-month history of skin diseases; it had been previously subjected to several treatments based on antibiotics, corticosteroids and antifungal drugs that have failed to show clinical improvements. Dermatological assessment has indicated generalized moist dermatitis, intense skin desquamation, alopecia, pruritus and meliceric crusts along the animal’s body, mainly in its dorsal region. Complementary tests, such as skin cytology and microscopy, trichogram, qualitative PCR and serology for canine visceral leishmaniasis, as well as fungal culture and antifungigram were requested based on this scenario. Serology recorded inconclusive results for leishmaniasis, whereas PCR recorded negative results in the presence of the agent’s DNA. Cytology, microscopy and trichogram results have evidenced fungal infection in the assessed samples. Moreover, mycological culture and antifungigram resulted in the growth of Candida sp. specimens capable of resisting antifungal agents such as amphotericin B, fluconazole, itraconazole and nystatin. The therapy adopted after candidiasis diagnosis confirmation comprised oral doses of manipulated ketoconazole, in combination to topical therapy with shampoo based on moisturizing formulas associated with Miconazole and Chlorhexidine (at 2%), for four weeks. After 30 days, when the adopted therapy was over, the aforementioned animal presented remission of the previously observed lesions and fully improved condition.
