The LPT was performed in sextuplicate, at concentrations of 18.75, 37.5, 75, 150 and 300 μg.mL-1. The LC50 found for the egg masses incubated with +7, +14 and +21 days were respectively 105.87, 110.71 and 121.22 μg.mL-1. The larvae originating from egg masses from the same group of engorged females, incubated on different days, presented similar mortality rates compared to the evaluated fipronil concentrations, facilitating the maintenance of laboratory colonies of this tick species.</p> Daniela de Oliveira Rocha Roxanne Marina da Silva Roque Thiago de Souza Vieira Brena Gava Guimarães Ingrid Lins Raquel de Jesus Marisa Beatriz da Silva Rocha Fabio Barbour Scott Barbara Rauta Avelar Copyright (c) 2023 Daniela de Oliveira Rocha, Roxanne Marina da Silva Roque, Thiago de Souza Vieira, Brena Gava Guimarães, Ingrid Lins Raquel de Jesus, Marisa Beatriz da Silva Rocha, Fabio Barbour Scott, Barbara Rauta Avelar 2023-03-22 2023-03-22 45 e005922 e005922 10.29374/2527-2179.bjvm005922 Ozone therapy: protocol for treating canine parvovirus infection <p>Canine Parvovirus infection is a disease caused by Canine Parvovirus (CPV) that results in hemorrhagic gastroenteritis and secondary infections, mainly in puppies between six weeks and six months old that are not immunized. Since there is no specific treatment for the condition, supportive therapy based on antibiotics, antiemetics, and non-steroidal anti-inflammatory drugs is traditionally used. Ozone therapy is an economical treatment that has bactericidal, fungicidal, and antiviral properties, besides promoting oxygenation and tissue regeneration, as well as anti-inflammatory and analgesic effects, and was used as a complementary therapy in this study. Therefore, four mixed-breed dogs, aged between 2 and 3 months, with no previous immunization against CPV and testing positive for the virus in a rapid test were selected. The animals were randomly distributed into two groups, being 1: the control group (n=2) that received only supportive treatment; and 2: the experimental group (n=2), that in addition to conventional therapy received intravenously 500 mL of ozonized Ringer’s Lactate solution. Before treatment and after 24 and 48 hours, the following clinical signs were evaluated: episodes of emesis and diarrhea, weight, hydration, blood glucose level, abdominal pain, and blood count. One control group animal died within the first hours of hospitalization. Both animals in the experimental group presented faster resolution of diarrheal episodes and shorter hospitalization time when compared to the surviving animal that received only supportive treatment. Although further studies are needed, ozone therapy showed promising results for the treatment of canine parvovirus.</p> Tiago Gonçalves dos Santos Jéssica Rodrigues Orlandin Matheus Ferreira de Almeida Rodrigo Ferreira Scassiotti Vanessa Cristina Oliveira Sarah Ingrid Pinto Santos Vitória Mattos Pereira Priscilla Avelino Ferreira Pinto Clésio Gomes Mariano Junior Carlos Eduardo Ambrósio Copyright (c) 2023 Tiago Gonçalves dos Santos, Jéssica Rodrigues Orlandin, Matheus Ferreira de Almeida, Rodrigo Ferreira Scassiotti, Vanessa Cristina Oliveira, Sarah Ingrid Pinto Santos, Vitória Mattos Pereira; Priscilla Avelino Ferreira Pinto; Clésio Gomes Mariano Junior, Carlos Eduardo Ambrósio 2023-02-11 2023-02-11 45 e004622 e004622 10.29374/2527-2179.bjvm004622 Successful early diagnosis and surgical treatment of congenital caval foramen hernia in an 8-month-old mixed breed cat <p>An 8-month-old neutered female domestic mixed breed cat was presented to Dr. L. Kriaučeliūnas Small Animal Clinic due to coughing that persisted for 2 weeks. Lateral and dorsoventral chest radiographs revealed an unusual dome-shaped soft tissue opacity mass that had contact with the cranial part of the diaphragm. Together with heart and abdominal ultrasound findings, we decided that one of the differential diagnoses was a diaphragmatic hernia. During the diagnostic celiotomy, a vertical 4 cm in length diaphragmatic deficit was visualized. Left medial and lateral liver lobes were herniated, yet healthy-looking. Adhesions between the liver lobes and the pericardium sac were visualized and dissected. The pericardium was sutured with simple interrupted suture pattern. A herniorrhaphy was performed suturing the diaphragm with the continuous suture pattern. Successful surgical treatment resulted in fully resolved clinical symptoms.</p> Dmitrij Kvitka Dalia Juodžentė Greta Rudenkovaitė Evelina Burbaitė Monika Laukutė Copyright (c) 2023 Dmitrij Kvitka, Dalia Juodžentė, Greta Rudenkovaitė, Evelina Burbaitė, Monika Laukutė 2023-01-27 2023-01-27 45 e005622 e005622 10.29374/2527-2179.bjvm005622 Hemorrhagic prostatic cyst in a dog – case report <p>We present the case of a five-year-old intact mixed breed male dog with hemorrhagic prostatic cysts. The patient presented with hematuria, dysesthesia, and pain on abdominal palpation. Abdominal ultrasound, hematology, urinalysis, and biochemical evaluation tests were subsequently conducted. Laboratory tests revealed cloudy urine with bacteria, and countless red blood cells. On ultrasound examination, the prostate was severely enlarged, with heterogeneous and reduced parenchyma, surrounding a large cavity filled with anechoic material with moderate cellularity. The urinary bladder was markedly distended and had a round, hypoechogenic structure in the lumen. The patient was hospitalized and had significant, irreversible worsening of the clinical symptoms and died. Subsequently, necropsy of the patient was performed and a histopathological diagnosis of benign prostatic hyperplasia associated with the presence of a prostatic hemorrhagic cyst, prostatitis, and chronic cystitis with an intraluminal blood clot was made. To the best of our knowledge, this is the first report to describe the occurrence of a hemorrhagic cyst in a canine prostate, thus bringing important information from clinical and imaging findings to the veterinary routine.</p> Bruna Bressianini Lima Brenda Santos Pompeu Miranda Denise Jaques Ramos Bibiana Lopes Tainara Morais Pereira Tamara Rodrigues Franco Ricardo Pozzobon Rafael Almeida Fighera Marcus Antônio Rossi Feliciano Copyright (c) 2023 Bruna Bressianini Lima, Brenda Santos Pompeu Miranda, Denise Jaques Ramos, Bibiana Lopes, Tainara Morais Pereira, Tamara Rodrigues Franco, Ricardo Pozzobon, Rafael Almeida Fighera, Marcus Antônio Rossi Feliciano 2023-01-13 2023-01-13 45 e005122 e005122 10.29374/2527-2179.bjvm005122 Updated spatial analysis of areas of occurrence of bovine cysticercosis in the state of Espírito Santo, Brazil <p>The risk of bovine cysticercosis is mutable over time, since population habits, local infrastructure, and bovine herd size change through the years. Hence, the aim of this study was to update the risk map of bovine cysticercosis occurrence in Espírito Santo State, Brazil, by choosing the following risk factors: inadequate sewer service; bovine population per municipality; risk of flooding; and land use and occupation, examined with a mathematical model using the GIS program ArcGis 10.5. The risk map of occurrence demonstrated that the state is composed of 12.8, 24.5, 36.2 and 26.5% of areas of very high, high, medium, and low risk, respectively. The northern area stood out for areas of very high risk, with the cities of Linhares and São Mateus accounting for 99% of the area with this classification. Of the state’s 78 municipalities, 15 had a portion of their territory with very high risk, 11 had over 50% of the territory with high risk and all except Irupi (100% of low risk) had some percentage of medium risk. These findings demonstrate the areas where actions to prevent bovine cysticercosis should be preferentially conducted.</p> Júlia Bertoli Gomes Barbara Rauta de Avelar Isabella Vilhena Freire Martins Copyright (c) 2023 Júlia Bertoli Gomes, Barbara Rauta de Avelar , Isabella Vilhena Freire Martins 2023-01-09 2023-01-09 45 e003622 e003622 10.29374/2527-2179.bjvm003622
