https://bjvm.org.br/BJVM/article/view/1328
<p>Tungiasis is an endemic dermatological parasitic zoonosis in Latin America, caused by the sand flea <em>Tunga </em>spp<em>. </em>(Siphonaptera, Tungidae), which promotes intense discomfort, swelling, erythema, itching, pain, secondary bacterial infection, cellulitis and necrosis. Sarolaner has been used to control different ectoparasites, but there is no record of its use for the treatment of tungiasis in dogs. The objective of this study was to evaluate the effectiveness of sarolaner for the treatment dogs naturally infested by <em>Tunga </em>spp<em>. </em>kept in the same infested environment. Three of four animals were medicated with sarolaner orally with a single dose of 2 mg/kg, as recommended by the manufacturer, and one animal remained without medication. After 24 hours, the fleas from all four dogs were mechanically removed. The animals were reevaluated on days +15 and +30 to assess possible reinfestation. The medicated animals remained free of fleas, while the untreated animal had fleas on the days previously defined for reevaluation. We can thus conclude that the use of sarolaner is an effective choice for tungiasis treatment.</p>Rafaella TortorielloNatália Lôres LopesBianca Bianco Paschoalino LinharesThais Ribeiro CorreiaJulio Israel Fernandes

https://bjvm.org.br/BJVM/article/view/1327
<p>Mesothelioma is a rare malignant neoplasm that affects the mesothelial cells lining the thoracic and abdominal cavities, such as the pleura, peritoneum, and pericardium. It is most prevalent in dogs and cattle, but the causes of this disease in animals are uncertain. In felines, it mainly affects the pleura, with an unfavorable prognosis. This paper explores a rare case of metastatic peritoneal mesothelioma in a 2-year-old female mixed breed cat, emphasizing its uniqueness due to the feline’s age. The patient, previously treated at a private clinic, presented moderate abdominal distension as the only clinical sign. Abdominal ultrasound and peritoneal fluid cytology led to the provisional diagnosis of mesothelioma/ carcinomatosis. One day after exploratory laparotomy, the animal died and was subsequently sent for necropsy. During macroscopic analysis, nodules were observed in the peritoneum, diaphragm, omentum, stomach serosa, and large intestine, and the diagnosis of solid epithelioid peritoneal mesothelioma with lung metastasis was confirmed after microscopic analysis. The diagnosis of mesothelioma is challenging, and the importance of immunohistochemical panels with specific markers such as cytokeratin AE1/AE3 and calretinin is highlighted. Considering that mesothelioma is a pathology with a poor prognosis, it is essential to include this disease in the list of differential diagnoses within veterinary oncology.</p>Heloísa Cristina Teixeira de CarvalhoLígia Fernandes GundimFelipe Martins PastorGabriel Henrique GuimarãesArlinda Flores ColetoMatias Pablo Juan SzabóAlessandra Aparecida Medeiros-Ronchi

https://bjvm.org.br/BJVM/article/view/1326
<p>Experimental animal facilities can have a negative impact on the well-being of animals owing to confinement. To mitigate this, environmental enrichment (EE) is implemented confinement. The purpose of EE is to enhance the complexity of an animal’s natural environment. The objective of this study was to identify the types of EE most enjoyed by dogs used in experimental research and housed in individual kennels. A total of six adult Beagle dogs, housed at the Laboratório de Quimioterapia Experimental em Parasitologia Veterinária (LQEPV) at the Universidade Federal Rural do Rio de Janeiro (UFRRJ) were included in the study. The EE tools used included Petball® toys, a grassy outdoor area, interaction with other dogs and with a team member, a “pool” made of plastic bottles, and dog’s wet food ice cream. A team member assessed the usage of these tools every 5 min for a 30-min period, six times per day, one day per week, over the course of eight weeks. The study revealed that the grass area was the tool most commonly used for physical enrichment, accounting for 58% of the occurrences (<em>p </em>< 0.05). Social and food enrichment were enjoyed in second and third place, with 23% and 19% of occurrences, respectively. that the study findings suggest that dogs housed in individual kennels enjoy engaging in their natural behaviors.</p>Anna Julia Bessa FernandesFernanda da Silva Freitas CamposGabriella Santos OliveiraPriscila Cardim OliveiraDebora Azevedo BorgesIvan de Alamar PedrosaFabio Barbour Scott

https://bjvm.org.br/BJVM/article/view/1324
<p>The study evaluated the effects of dietary supplementation with <em>Lippia sidoides </em>essential oil on the microbiota and intestinal morphology of <em>Danio rerio</em>. For this, 448 fish were randomly distributed in 28 tanks divided into a control group fed a commercial diet without supplementation, a group fed a commercial diet containing grain alcohol and five groups fed a commercial diet containing essential oil of <em>L. sidoides </em>(LSEO) at concentrations of 0.25%, 0.50%, 0.75%, 1.00% and 1.25%. After the period of dietary supplementation, biological materials were collected for microbiological and histological analyses. There were no significant differences regarding the microbiological count between the groups. Diversity of the microbiome was higher in 0.25% group than in control group. LSEO inhibited the growth of potentially pathogenic bacteria. Fish fed LSEO0.25% showed greater intestinal histomorphometric indices. The inclusion of LSEO at 0.25% in the diet of <em>D. rerio </em>provided improvements in fish microbiota and intestine integrity.</p>Lucas CardosoMarco Shizuo OwatariFrancisco Célio Maia ChavesTamiris Henrique FerreiraDomickson Silva CostaWilliam Eduardo FurtadoMarília TedescoLuciana Aparecida HonoratoJosé Luiz Pedreira MouriñoMaurício Laterça Martins

https://bjvm.org.br/BJVM/article/view/1323
<p><em>Dioctophyme renale </em>is a nematode with zoonotic potential that affects the kidneys of carnivorous, wild, and domestic mammals. In this study, we sought to evaluate the indirect ELISA method against routine methods used to diagnose dioctophimosis. Hence, 38 dogs parasitized by <em>D. renale</em>, as confirmed by surgery, were selected. The dogs were evaluated by abdominal ultrasound and urinalysis, and their sera were tested by indirect ELISA using <em>D. renale </em>adult secretion and excretion antigen (DES). Five dogs were followed up with serum collections on day 0 (day of surgery) and 30, 60, and 90 days after surgery to evaluate antibody kinetics. Abdominal ultrasound and indirect ELISA successfully diagnosed 37 dogs parasitized by <em>D. renale</em>, while urinalysis diagnosed 29 animals. The positive animals were parasitized with 1–7 parasites; 17 dogs were infected by male and female parasites, 15 only by female parasites, and six were parasitized only by male parasites. When assessing specificity and sensitivity, all techniques showed 100% specificity and 81.6%, 97.4%, and 97.4% sensitivity for urinalysis, ultrasound, and ELISA, respectively (<em>p </em>< 0.001). The five positive dogs that were followed up after surgery showed a progressive decrease in mean absorbances in indirect ELISA (0.644, 0.516, 0.511, and 0.440, respectively). This study demonstrated that the indirect ELISA using the DE antigen could diagnose dioctophimosis regardless of the number, sex, and location of the parasites, with the potential to be used in epidemiological research and implementing immunological and molecular studies, opening new lines of research on <em>D. renale. </em></p>Gabriela de Almeida CapellaJosaine Cristina da Silva RappetiNatalia Berne PinheiroSoliane Carra PereraMicaele Quintana de MouraMarlete Brum CleffCaroline Maciel da CostaAdriane Leites StrothmannGuilherme Borges WeegeCarolina Silveira MascarenhasMaria Elisabeth Aires Berne
