A rangeliose canina é uma doença hemolítica extravascular causada pelo protozoário Rangelia vitalii, o qual é transmitido por carrapatos da espécie Amblyomma aureolatum. Os sinais clínicos mais comuns são apatia, hipertermia e sangramentos espontâneos. Os achados hematológicos mais comuns são anemia e trombocitopenia. Este trabalho teve como objetivo relatar um caso clínico de Rangeliose canina tratada em um hospital veterinário particular, na cidade de São Paulo no ano de 2017. Um cão foi atendido em um hospital veterinário da zona norte de São Paulo, com emagrecimento progressivo, apatia e lesão na cauda. No hemograma foram observadas anemia e trombocitopenia. Através da PCR em tempo real (qPCR) do sangue do animal constatou-se a presença de DNA de Rangelia vitalii. Além do tratamento de suporte, utilizou-se doxiciclina e aplicações subcutâneas de imidocarb. A amostra coletada após o tratamento com o antibiótico continuou apresentando DNA do protozoário. A enfermidade deve ser considerada como diagnóstico diferencial e há uma grande necessidade de maiores estudos acerca da terapia utilizada. | Canine rangeliosis is an extravascular hemolytic disease caused by the protozoan Rangelia vitalii, which is transmitted by ticks of the species Amblyomma aureolatum. Te most common clinical signs are apathy, hyperthermia and spontaneous bleeding. Anemia and thrombocytopenia are the most common hematological fndings. Tis work reports a clinical case of canine Rangeliosis treated at a private veterinary hospital, in São Paulo city in 2017. A dog was treated at a veterinary hospital in the north of São Paulo, with progressive weight loss, apathy and tail injury. Anemia and thrombocytopenia were observed on the hemogram. Rangelia vitalii DNA was detected in animal blood by real-time PCR (qPCR). In addition to the supportive treatment, doxycycline and subcutaneous imidocarb applications were used. Te sample collected afer treatment with the antibiotic continued to present protozoal DNA. Te disease should be considered as a diferential diagnosis and there is a great need for further studies about the therapy used.

O frênulo peniano é uma fina faixa de tecido conectivo que une a glânde ao prepúcio que pode se romper sob a ação da testosterona quando o animal inicia a puberdade. Devido a escassez de relatos desta afecção o presente trabalho relata a ocorrência de frênulo peniano persistente em um gato doméstico, sem raça definida, de sete meses de idade e 5,2 kg. O frênulo peniano foi um achado incidental durante o exame clínico do animal. O animal já apresentava‑se em puberdade, caracterizando o quadro de frênulo peniano. A resolução do caso ocorreu de maneira espontânea previamente a orquiectomia eletiva. Dessa forma, as alterações observadas no pênis devido a alteração congênita em gatos são descritas neste relato.   | The penile frenulum is a thin strip of connective tissue that connects the penis glans to the foreskin. Due to the few number of reports of this condition, this work reports the occurrence of persistent penile frenulum in a mixed breed domestic cat, of seven months old and 5.2 kg. In this particular case, penile frenulum was an incidental finding during clinical examination. The animal was in puberty, characterizing the penile frenulum. The resolution of the case occurred spontaneously prior to elective orchiectomy. Thus, the changes observed in the penis due to congenital alteration in cats are described in this report.

O presente trabalho descreve os sinais clínicos, as lesões macroscópicas e os aspectos histológicos observados em 25 cordeiros acometidos em um surto de artrogripose congênita com hidrocéfalo ou hidrocefalia registrado no Iraque, governadoria Al-Muthama após a ocorrência de nascimentos prematuros e deformidades músculo-esqueléticas no período compreendido entre outubro de 2017 e maio de 2018. A hipoplasia músculo-esquelética foi observada nos membros dos cordeiros afetados, acompanhada de severa artrogripose e malformações cerebrais, grosseiras visíveis, além de mumifcações fetais, nascimentos prematuros e morte de cordeiros. Os principais aspectos histopatológicos nas fbras musculares foram lesões degenerativas e ausências da estriação cruzada acompanhada de leve infltração de neutróflos e células mononucleares dos cordeiros severamente afetados. As meninges dos cordeiros afetados apresentaram fusão de membranas com áreas focais de espessamento fbroso e debris necróticos. O vírus Akabane, um membro do gênero Orthobunyavirus, da família Bunyaviridae, causa anormalidades congênitas e artrogripose com hidrocéfalo e hidrocefalia em ruminantes e poderá vir a ser a causa do presente surto. Os autores recomendam a realização de novos estudos com investigações epidemiológicas e isolamento do agente causal. Contudo, outras causas de hidrocéfalo ou malformações cerebrais como as determinadas pelo vírus Schmallenberg, vírus da língua azul e vírus da doença de border, bem como de plantas teratogênicas que determinam a artrogripose, também deverão ser investigadas. As autoridades sanitárias deverão tomar medidas de prevenção e controle para bloquear a replicação do vírus em artrópodes vetores. | Akabane virus, a member of the Orthobunyavirus genus in the family Bunyaviridae, causes congenital abnormalities and arthrogryposis with hydrocephalus or hydroencephaly in ruminants. Tis study intends to describe the clinical signs, gross and histopathological features seen in 25 afected lambs in an outbreak of congenital arthrogryposis with hydrocephalus or hydranencephaly in Al-Muthanna governorate, Iraq afer a large number of stillbirths and musculoskeletal deformities from October 2017 to May 2018. Skeletal muscle hypoplasia was seen in the limbs of the afected lambs accompanied with severe arthrogryposis and gross visible brain malformations. In addition, fetal mummifcations, stillbirths, and dead lambs were also seen. Te most histopathological features in muscle fbers were degenerative lesions and absences of cross-striation accompanied with mild infltration of neutrophils and mononuclear cells in severely afected lambs. Te meninges of afected lambs revealed fused membranes with focal areas of fbrous thickenings and necrotic debris. In conclusion, according to clinical signs, gross and histopathological investigations, Akabane virus, a member of the Orthobunyavirus genus in the family Bunyaviridae, causes congenital abnormalities and arthrogryposis with hydrocephalus or hydroencephaly in ruminants and could be the cause of this outbreak, although future studies must be performed to confrm the etiology of this outbreak. Moreover, other causes of hydrocephalus or cerebellar malformation, such as Schmallenberg virus, bluetongue virus and border disease virus and teratogenic plants that lead to arthrogryposis, have to be investigated. Also, the authorities should take prevention and control measurements to stop the replication of arthropod vectors.

O antígeno eritrocitário canino 1 (AEC 1) é o grupo sanguíneo mais imunogênico em cães, podendo as transfusões sanguíneas desencadearem alguns efeitos indesejáveis nos pacientes veterinários. Estes estão diretamente associados à transfusões incompatíveis. O presente trabalho teve como objetivo estudar a frequência do grupo sanguíneo AEC 1 em cães doadores de sangue de um banco de sangue de Salvador-BA, Brasil, e calcular o risco de administrar sangue incompatível tanto em uma primeira quanto em uma segunda transfusão. Foram avaliados 203 cães de diversas raças, de ambos os sexos, com idade entre 1 e 8 anos, peso a partir de 28 kg, sem nenhum grau de parentesco originários de Salvador – BA, Brasil, para pesquisa da frequência do tipo sanguíneo AEC 1, por meio de testes de imunocromatografia e citometria de fluxo para tipagem sanguínea. E calculado o risco de transfusão sanguínea incompatível tanto em uma primeira como em uma segunda transfusão. A frequência do grupo AEC 1 variou entre as raças estudadas de 0% a 100%, porém com uma positividade média de 62,07% (126/203). O menor risco de um animal AEC 1 negativo receber sangue AEC 1 positivo, dentro do grupo dos animais avaliados foi de 0,92% em uma primeira transfusão e o risco do mesmo animal receber sangue incompatível para o gruo AEC 1 na segunda transfusão foi de 0,008%. Quanto ao maior risco de um animal AEC 1 negativo receber sangue AEC 1 positivo destes animais foi de 69,12% e o risco do mesmo receber sangue incompatível para o AEC 1 foi de 47,77%.  A frequência do grupo AEC 1 variou entre as raças estudadas e o risco de transfusões incompatíveis variou de acordo com as raças doadoras e receptoras, mas esse risco pode ser anulado se sempre forem realizados os testes para tipagem sanguínea junto com a prova de reação cruzada para compatibilidade. | The dog erythrocyte antigen 1 (DEA 1) is the most immunogenic blood group in dogs, and blood transfusions may trigger some undesirable effects in veterinary patients, which are directly associated with incompatible transfusions. The present study aimed to investigate the frequency of positive DEA 1 blood group in blood donor dogs from a blood bank in Salvador, Bahia, Brazil, and also to calculate the risk of managing incompatible blood in both first and second transfusion. A number of 203 dogs of different breeds, aged between 1 and 8 years, weighing 28 kg, with no degree of kinship and of both sexes in Salvador - BA, Brazil were evaluated to investigate the blood type DEA 1 frequency, by means of chromatography and flow cytometry tests for blood typing. The risk of incompatible blood transfusion in either a first or a second transfusion was also calculated. The frequency of the DEA 1 group ranged from 0% to 100% in various breeds, but with a mean positivity of 62.07% (126/203). And the lowest risk of an DEA 1 negative animal receiving DEA 1 positive blood within the group of animals evaluated was 0.92% at a first transfusion; and the risk of the same animal receiving incompatible blood for the DEA group 1 in the second transfusion was 0.008%. The highest risk of an DEA 1 negative animal receiving DEA 1 positive blood from these animals was 69.12%; and the risk of receiving incompatible blood for DEA 1 was 47.77%. In conclusion, the frequency of the DEA 1 group varied between the studied breeds and the risk of incompatible blood transfusions varies according to donor and recipiente breeds, but this can be overridden if blood typing tests are performed along with the cross-reaction test for compatibility.

O Brasil está entre os maiores produtores de leite do mundo e a maioria dos estabelecimentos são de pequenos produtores da agricultura familiar. O leite é um produto perecível e devido as suas características nutricionais proporciona um ambiente favorável para o crescimento de bactérias. O objetivo desta pesquisa foi avaliar os hábitos de consumo de leite em propriedades da agricultura familiar, identificando as formas de consumo, avaliando os riscos e a percepção de risco pelos produtores, além de avaliar o manejo sanitário adotado nas propriedades com relação às doenças transmitidas pelo leite e derivados. Foram entrevistados 111 produtores do município de Realeza-PR. Das propriedades pesquisadas, quase metade (48,64%, 54/111) tinham uma pequena produção com até 10 animais em lactação. A maioria dos produtores possuía animais com uma baixa produtividade, sendo que a produção média de leite por animal foi menor que 10 litros. O leite produzido era consumido internamente por 93,67% (104/111) dos entrevistados e 7,2% (8/111) firmaramingerir o leite cru sem qualquer tratamento térmico prévio. Alguns produtores (18%, 20/111) ainda faziam derivados com o leite, como queijo e doce de leite. Apesar de 82,87% (92/111) afirmarem ter conhecimento sobre a transmissão de doenças pelo produto, apenas 49,54% (55/111) nomearam as doenças. Com relação a realização de exames, nem todos os produtores os realizavam. O presente trabalho ainda constatou que apenas 4 pessoas entrevistadas (3,6%, 4/111) associaram o consumo de leite cru a algum mal estar e afirmaram apresentar alguns sintomas como, vômito, enjoo, alergia de pele, cólica e gases. Devido a isso, se faz necessário informar e orientar os produtores sobre os riscos associados ao consumo de leite, para que assim não só a saúde do produtor seja assegurada, mas da família e da população que pode adquirir este produto informalmente.  | Brazil is one of the largest milk producers in the world and most establishments are small producers of family farming. Milk is a perishable product and due to its nutritional characteristics provides a favorable environment for the growth of bacteria. The objective of this research was to evaluate the consumption habits of milk in family farms, identifying the consumption forms, evaluating the risks and the perception of risk by the producers, besides evaluating the sanitary management adopted in the properties with respect to the diseases transmitted by the milk and milk products. One hundred eleven producers from the city of Realeza-PR were interviewed. Almost half (48.64%, 54/111) had a small production with up to 10 lactating animals. Most of the producers had animals with a low productivity, and the average milk production per animal was less than 10 liters. The milk produced was consumed internally by 93.67% (104/111) of those interviewed, and 7.2% (8/111) claim to ingest raw milk without any previous heat treatment. Some producers(18%, 20/111) still made dairy products, like cheese and dulce de leche. Although 82.87% (92/111) reported having knowledge about the transmission of diseases through milk, only 49.54% (55/111) named the diseases. Not all producers conducted tests in the herd for disease control. The present study also found that only 4 people interviewed (3.6%, 4/111) associated the consumption of raw milk with some illness and reported having some symptoms, such as vomiting, nausea, skin allergy, colic and gas. Thus, it is necessary to inform and guide producers about the risks associated with raw milk consumption, so that not only the health of the producer is assured, but also the family and the population that may acquire this product informally.

Diversos estudos evidenciam a presença de protozoários do gênero Nematopsis Schneider, 1892 em várias espécies de bivalves. A patogenicidade desse apicomplexo ainda é bastante debatida, a qual possivelmente relaciona-se ao grau de parasitismo e habitat do hospedeiro. Nesse contexto, este estudo investigou o parasitismo por Nematopsis sp. em Mytella guyanensis (Bivalvia: Mytilidae) em um manguezal da Reserva Extrativista Marinha Baía do Iguape, Bahia, Brasil. As coletas foram efetuadas mensalmente, de março de 2014 a março de 2015, constando 30 adultos com altura da concha acima de 40 mm, totalizando 360 espécimens. Os espécimens foram medidos, pesados, abertos e examinados macroscopicamente para a identificação de parasitos e/ou sinais de alterações morfológicas, em seguida fixados em solução de Davidson e processados segundo técnica histológica clássica, com inclusão em parafina, obtenção de cortes de 5 μm de espessura por microtomia e coloração por hematoxilina de Harris e Eosina (HE). A temperatura da água variou de 25,5 a 33,6 ºC e a salinidade de 21,1 a 34,3 Unidades Práticas de Salinidade (UPS). Os espécimens mediram entre 41,1 e 68,6 mm e tiveram um peso médio de 7,24 g. Macroscopicamente, não se observou presença do parasito ou qualquer alteração morfológica relacionada à presença do mesmo. A frequência percentual de Nematopsis sp. foi de 99,45%. O manto foi o órgão de maior frequência de infecção(46,26%), seguido das gônadas (18,36%). Entre os órgãos analisados, todos apresentaram o parasito, sendo que, para poucos casos severamente infectados, observaram-se microscopicamente modificações na conformação do manto. A intensidade de infecção para a maioria das sessões analisadas foi de 1 a 3 oocistos/fagócitos, contudo em uma das sessões foram registrados 9 oocistos/fagócitos. O parasito apresentou correlação negativa com a salinidade. A elevada frequência do Nematopsis sp. deve ser levada em consideração para a sustentabilidade dos estoques naturais, principalmente se tal parasitismo ocorrer simultaneamente a outros patógenos e condições ambientais estressantes. | Several studies show the presence of protozoa of the genus Nematopsis Schneider, 1892, in many species of bivalves. The pathogenicity of this Apicomplexa is still much debated, which is possibly related to the parasitism degree and host habitat. In this context, this study investigated parasitism by Nematopsis sp. in Mytella guyanensis (Bivalvia: Mytilidae) in a mangrove of the Marine Extractive Reserve Baía do Iguape, Bahia, Brazil. The collections were made monthly, from March 2014 to March 2015, consisting of 30 adults with shell height above 40 mm per month, totaling 360 specimens. The specimens were measured, weighed, opened, and macroscopically examined for identifying parasites and/or signs of morphological changes. After that, they were fixed in Davidson’s solution and processed according to classical histological techniques, with inclusion in paraffin, obtaining 5 μm-thick sections by microtomy, and stained by Harris’ Hematoxylin and Eosin (HE). The water temperature ranged from 25.5 to 33.6 ºC and the salinity from 21.1 to 34.3 Practical Salinity Units (PSU). The specimens measured between 41.1 and 68.6 mm and had an average weight of 7.24 g. Macroscopically, there was no presence of the parasite or any morphological changes related its presence. The frequency percentage of Nematopsis sp. was 99.45%. The mantle was the organ with the highest frequency of infection (46.26%), followed by the gonads (18.36%). Among the analyzed organs, all presented the parasite and, in a few severely infected cases, microscopical changes were observed in the mantle conformation. The infection intensity for most of the sessions analyzed was 1 to 3 oocysts/phagocyte; however, in one of the sessions, 9 oocysts/phagocytes were recorded. The parasite had a negative correlation with salinity. The high frequency of Nematopsis sp. should be considered for the sustainability of natural stocks, especially if such parasitism occurs simultaneously with other pathogens and stressful environmental conditions.

O Vírus da Imunodeficiência Felina (FIV) e o Vírus da Leucemia Felina (FeLV) são importantes agentes etiológicos de doenças imunossupressoras em felinos. O objetivo do presente estudo foi determinar a prevalência desses retrovírus em gatos domésticos em Fortaleza, Ceará e os fatores epidemiológicos associados a essas infecções. Entre 2015 e 2016, foram coletadas 138 amostras de sangue e testadas para FIV e FeLV pelo ensaio de imunoadsorção enzimática (ELISA). Parâmetros como raça, gênero, idade, estado reprodutivo, ambiente com vários gatos, acesso ao ar livre e manifestações clínicas foram avaliados. Os resultados mostraram que 12,32% foram positivos para o FIV, 5,80% para o FeLV e 1,45% para a co-infecção (FIV/FeLV). Os animais FIV+ eram na sua maioria gatos machos castrados, adultos, de raça mista, com estilo de vida dentro de casa e vivendo em um ambiente com vários gatos. A manifestação clínica mais comum observada foi distúrbios da cavidade oral. Os fatores encontrados que aumentam o risco de soropositividade para FeLV incluem gatas fêmeas castradas, jovens, de raça mista, com estilo de vida dentro de casa e vivendo em um ambiente com vários gatos, foram os fatores epidemiológicos mais comuns observados. A manifestação clínica mais comum foi anorexia e apatia. A prevalência desses vírus foi relativamente alta em comparação com outras regiões do Brasil. Este estudo demonstrou que os animais de raça mista, castrados, vivendo em um ambiente com vários gatos e estilo de vida dentro de casa são de maior relevância para as doenças infecciosas por FIV e FeLV. Fatores relacionados à demografia e à saúde do gato, como idade, sexo e tipo de domicílio, são importantes preditores do estado soropositivo para FeLV ou FIV em Fortaleza. A alta prevalência de FeLV ou FIV observada em nosso estudo é preocupante, tendo em vista o potencial imunossupressor dos dois patógenos. | Feline Immunodeficiency Virus (FIV) and Feline Leukemia Virus (FeLV) are important etiologic agents of immunosuppressive diseases in felines. The objective of the present study was to determine the prevalence of these retroviruses in domestic cats in Fortaleza, Ceará and the epidemiological factors associated with these infections. Between 2015 and 2016, 138 blood samples were collected and tested for FIV and FeLV by the enzyme immunoadsorption assay (ELISA). Parameters such as breed, gender, age, reproductive status, multi-cat environment, outdoor access and clinical manifestations were evaluated. The results showed that 12.32% were positive for FIV, 5.80% for FeLV and 1.45% for co-infection (FIV/FeLV). FIV+ animals were mostly mixed breed, neutered male adult cats, with indoor lifestyle and living in a multi-cat household. The most common clinical manifestation observed was disorders of the oral cavity. Factors found to increase the risk for FeLV seropositivity include mixed breed, young, spayed female cats, indoor lifestyle living in a multi-cat household were the most common epidemiological factors observed. The most common clinical manifestation was anorexia and apathy. The prevalence of these viruses were relatively high, compared with other region of Brazil. This study demonstrated that mixed breed, castrated, multi-cat environment and indoor lifestyle animals are of greater relevance for FIV and FeLV infection diseases. Factors related to cat demographics and health such as age, sex and type of household are important predictors for seropositive status to FeLV or FIV in Fortaleza. High prevalence of FeLV or FIV observed in our study is of concern, in view of the immunosuppressive potential of the two pathogens.

O presente relato descreve um cão Pit Bull, de 14 anos, com aumento de volume de consistência macia em região sublingual direita com evolução de 3 meses. Após excisão cirúrgica, a análise histopatológica revelou grande número de adipócitos maduros, tecido glandular composto por ductos dilatados e ácinos atróficos contendo mucina, circundados por fina cápsula fibrosa, achados compatíveis com sialolipoma da glândula salivar sublingual. Pelo conhecimento dos autores, este é o primeiro relato de sialolipoma acometendo glândula salivar sublingual em cão. | This report describes a 14-year-old Pit Bull dog presenting with a soft tissue swelling of 3-month progression in the right sublingual region. Histopathological analysis of the surgically resected specimen revealed large numbers of mature adipocytes and islets consisting of mucin-containing atrophic acini and dilated ducts surrounded by a thin fibrous capsule. Findings were consistent with sialolipoma of the sublingual salivary gland. To the authors’ knowledge, this is the first case of sialolipoma affecting the sublingual salivary gland in dogs.
