The adoption of management practices to prevent the introduction and spread of pathogens depends on various factors, including demographics, awareness of the problem, perceived responsibility, previously held beliefs, and sociocultural norms. This study aimed to evaluate the health management practices and the level of knowledge about infectious diseases of equine owners in the state of Rio Grande do Norte, Brazil. A cross-sectional study was conducted by distributing a questionnaire to horse owners in Rio Grande do Norte, Brazil. The participants included horse owners irrespective of the duration of ownership, experience, or sports practiced. In addition to the hygiene and management of animals, the questionnaire addressed topics related to the facilities where the horses were kept. Three hundred and two horse owners distributed in 60 of the 167 municipalities in the state of Rio Grande do Norte participated in this study. Among the interviewed owners, 63.90% (193/302) answered that they do not quarantine animals introduced into the herd or those visiting the property. Regarding the deworming program, 95.03% (287/302) of the owners regularly dewormed their animals. However, more than half of the participants sought veterinary guidance (54.30%). Investing in educational programs and increasing the awareness of equine owners in the state of Rio Grande do Norte about the main infectious diseases in horses is essential toward improving sanitary management and the general health of animals. Informed owners play an essential role in creating safer environments for their horses, thereby contributing to the sustainability of the equine industry.</p> Paulo Roberto Medeiros , Liliany Silva Figueiredo, Ubiratan Pereira de Melo, Amanda Louíse Bittencourt Mariz, Emilson Lima de Brito Filho, Ingrid Raquel dos Santos Araújo, Allyson Lincoln Da Costa Silva Junior, Mariana Henrique da Silveira Costa, Cintia Ferreira, Daniel Barbosa Assis, Camilla Raylly Miguel da Silva, Aldemir Lopes de Souza, Magna Pereira da Silva de Souza Copyright (c) 2023 Paulo Roberto Medeiros , Liliany Silva Figueiredo, Ubiratan Pereira de Melo, Amanda Louíse Bittencourt Mariz, Emilson Lima de Brito Filho, Ingrid Raquel dos Santos Araújo, Allyson Lincoln Da Costa Silva Junior, Mariana Henrique da Silveira Costa, Cintia Ferreira, Daniel Barbosa Assis, Camilla Raylly Miguel da Silva, Aldemir Lopes de Souza, Magna Pereira da Silva de Souza https://creativecommons.org/licenses/by/4.0 https://bjvm.org.br/BJVM/article/view/1305 Mon, 27 Nov 2023 00:00:00 -0300 Feline congenital hypothyroidism: a case report https://bjvm.org.br/BJVM/article/view/1304 <p>We report a two-month-old male cat weighing 630 grams with congenital hypothyroidism. The main complaints were difficulty defecating for more than three days and prostration. Physical examination revealed a broad, flat face, a short neck, enlarged submandibular lymph nodes, chemosis, mild bilateral mucopurulent ocular discharge, seborrheic coat, with gingival thickening around the upper and lower deciduous incisor teeth with partial eruption. The abdomen was distended due to constipation and right unilateral cryptorchidism. Based on this, feline congenital hypothyroidism was suspected. Hormonal tests (free T4 by equilibrium dialysis of 0.06 ng/dl, total T4 of 0.1 ng/ml and TSH of 4.7 ng/ml) confirmed this. Treatment was started with levothyroxine sodium (5-32.2 µg/kg/day). After 120 days of treatment, there was clinical stabilization. Then the patient underwent orchiectomy of the left and of the right ectopic testicles, and at 380 days of treatment, the thyroid scintigraphy showed intense uptake of the radiopharmaceutical by both thyroid lobes and a significant increase in volume. Clinical evaluation showed weight gain (2.6 kilograms during treatment), improvement in the shape of the skull, and a notable increase in body size. At 17 months of age, hormone values were within the reference limits after administration of levothyroxine sodium (32.2µg/kg/day).</p> Gabriella Carvalho Abend, Stephanie Favato de Azevedo, Arthur Saturiano dos Santos, Gustavo Carvalho Cobucci, Heloisa Justen Moreira de Souza Copyright (c) 2023 Gabriella Carvalho Abend, Stephanie Favato de Azevedo, Arthur Saturiano dos Santos, Gustavo Carvalho Cobucci, Heloisa Justen Moreira de Souza https://creativecommons.org/licenses/by/4.0 https://bjvm.org.br/BJVM/article/view/1304 Fri, 10 Nov 2023 00:00:00 -0300 Frequency of Dirofilaria immitis infection in blood donor dogs of the Rio de Janeiro state https://bjvm.org.br/BJVM/article/view/1303 <p>Dirofilariasis, a parasitic disease caused by the nematode <em>Dirofilaria immitis</em>, commonly known as heartworm, primarily inhabits the pulmonary artery and right heart of dogs and other animals. The disease is transmitted through diptera, predominantly from the <em>Culex</em>, <em>Aedes</em>, and <em>Anopheles </em>genera. Dirofilariasis is cosmopolitan in nature, endemic in coastal regions and tropical climates. Factors such as temperature, humidity, vector density, and the presence of definitive hosts significantly contribute to the spread of this parasitic disease. In the state of Rio de Janeiro, a prevalence of 58.6% of <em>D. immitis </em>infected animals has been recorded in municipalities like Niterói. Given that blood transfusions are routine clinical procedures and blood bags are not always accurately evaluated, an investigation into <em>D. immitis </em>infection in blood donor dogs from the metropolitan region of Rio de Janeiro was conducted. A total of 1044 blood donor dog files from a blood bank in Niterói, RJ, collected from January 2019 to December 2022, were analyzed. These samples, originating from kennels in various municipalities in the Metropolitan Region, were tested for the presence of microfilariae through direct examination using tubes and microhematocrit evaluated in optical microscopy. Additionally, the search for antigens was conducted using the enzyme-linked immunosorbent assay technique. Out of the 1044 records evaluated, 17.8% (186/1044) were positive for heartworm infection, with 2% (21/1044) samples positive for microfilariae and 14.8% (154/1044) positive for <em>D. immitis </em>antigens. The high prevalence rate indicates that canine <em>D. immitis </em>infection remains prevalent in the state of Rio de Janeiro, necessitating effective guidelines for prescribing preventive medications by veterinarians and an increase in epidemiological surveillance in the region.</p> Genilson Pereira Gonçalves Junior, Suzane Gallardo Xavier, Nathália da Conceição Lima, Alexandre José Rodrigues Bendas Copyright (c) 2023 Genilson Pereira Gonçalves Junior, Suzane Gallardo Xavier, Nathália da Conceição Lima, Alexandre José Rodrigues Bendas https://creativecommons.org/licenses/by/4.0 https://bjvm.org.br/BJVM/article/view/1303 Wed, 11 Oct 2023 00:00:00 -0300 Molecular analysis of canine circovirus in dogs from animal shelters in Belém, Pará, northern Brazil: first detection at the amazon region https://bjvm.org.br/BJVM/article/view/1302 <p>The canine circovirus (CanCV) is a single-stranded DNA virus that has become an important emerging virus associated with gastroenteritis in dogs worldwide. In the present study, the CanCV was detected by PCR in 15% (22/147) of dogs from animal shelters in Belém, between 2019 and 2020. We observed an association between the CanCV infection and the presence of diarrhea in animals younger than one year of age (p &gt; 0.01). The Brazilian strains were grouped in Chinese genotypes, with 99.54 to 100% nucleotilde homology. The GMRF Bayesian Skyride used the molecular clock model, which was the best suited technique to plot the dataset. The most recent common ancestor (TMRCA) was estimated in 2017, with the evolution rate of 1.6 x 10-3 s/s/y. The viral family diversity was also investigated, with emphasis on the families of the enteric pathogenic viruses Parvoviridae, Picornaviridae and Astroviridae, which were detected in the CanCV positive pooled samples. This study highlights the importance of the CanCV as an emergent virus that causes diarrhea in Brazilian dogs. The results found herein contribute to the understanding of the role of CanCV in enteric diseases and in the evolutionary molecular characterization of the circulating genotypes. Furthermore, we increased the understanding of the fecal virome in dogs with diarrhea, providing data for the monitoring and prevention viral gastroenteric diseases in domestic animals.</p> Bruna Trindade Moreira Cardoso, Danielle Rodrigues de Deus, Edivaldo Costa Sousa Junior, Kenny da Costa Pinheiro, Jonaia Novaes da Costa, Marcelino Antonio Costa Maués, Márcia Janete de Fátima Mesquita , Dielle Monteiro Teixeira, Jones Anderson Monteiro Siqueira, Hugo Reis Resque, Yvone Benchimol Gabbay, Luciana Damascena da Silva Copyright (c) 2023 Bruna Trindade Moreira Cardoso, Danielle Rodrigues de Deus, Edivaldo Costa Sousa Junior, Kenny da Costa Pinheiro, Jonaia Novaes da Costa, Marcelino Antonio Costa Maués, Márcia Janete de Fátima Mesquita , Dielle Monteiro Teixeira, Jones Anderson Monteiro Siqueira, Hugo Reis Resque, Yvone Benchimol Gabbay, Luciana Damascena da Silva https://creativecommons.org/licenses/by/4.0 https://bjvm.org.br/BJVM/article/view/1302 Tue, 03 Oct 2023 00:00:00 -0300 Evaluation of the effect of Heterorhabditis bacteriophora (HP88) on Stomoxys calcitrans (Linnaeus, 1758) larvae (Diptera: Muscidae) in sugarcane bagasse ash https://bjvm.org.br/BJVM/article/view/1301 <p>The purpose of this study was to evaluate the effect of the EPN <em>Heterorhabditis bacteriophora </em>HP88 on <em>Stmoxys. calcitrans </em>larvae in sugarcane bagasse ash. Groups of 10 stable fly larvae were placed in Petri dishes containing filter paper and bagasse ash. Concentrations of 50, 150 and 250 EPNs/larva of <em>S. calcitrans </em>in four milliliters of distilled water were added to each plate. In the control group contained only distilled water, without EPNs. The bioassay had three replications and was maintained at 27 ± 1°C and 70-80% relative humidity. It was observed that mortality rate in all treated groups was significantly higher than in the control group (26,6%). The mortality rate in the presence of 50 EPNs/larva (46,6%) was lower than in 150 EPNs/larva (76,3%), which in turn was lower than 250 EPNs/larva group (93,3%). It was verified by analysis of variance and regression that there was a linear pattern of mortality, that is, the higher the EPNs/larva concentration, the higher the larval mortality. It was concluded that EPN <em>H. bacteriophora </em>HP88 was capable of infecting and causing mortality of stable fly larvae in sugarcane bagasse ash.</p> Américo de Castro Monteiro Sobrinho, Ana Caroline Ferreira de Souza, Danielle Pereira da Silva, Graziele Calixto Souza, Isadora Luiza Alves Costa, João Luiz Lopes Monteiro Neto, Melissa Carvalho Machado do Couto Chambarelli, Avelino José Bittencourt Copyright (c) 2023 Américo de Castro Monteiro Sobrinho, Ana Caroline Ferreira de Souza, Danielle Pereira da Silva, Graziele Calixto Souza, Isadora Luiza Alves Costa, João Luiz Lopes Monteiro Neto, Melissa Carvalho Machado do Couto Chambarelli, Avelino José Bittencourt https://creativecommons.org/licenses/by/4.0 https://bjvm.org.br/BJVM/article/view/1301 Mon, 02 Oct 2023 00:00:00 -0300
