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.

Neuropathies of pharyngeal branches of glossopharyngeal and vagus are often associated with guttural pouches diseases; however, these branches of injury due to stylopharyngeus muscle compression are not reported. A case was reported of a quarter horse mare, 8 years old, 450 kg, presenting dyspnea and respiratory noise associated with weight loss. Clinical examination observed mixed dyspnea, tachycardia, dysphagia, sialorrhea, lung crackles and submandibular and parotid lymphadenopathy. Endoscopic exam showed right arytenoid chondritis, nasopharyngeal collapse, generalized larynx edema and dorsal displacement of the soft palate. Right guttural pouch evaluation showed swelling in the origin of stylopharyngeus muscle with consequent compression of the XII, X and IX cranial nerves. Tracheotomy, systemic treatment with corticosteroids, beta lactams and aminoglycosides antibiotics were performed. No resolution was observed and, after 16 days, the animal showed clinical worsening, developed pleuropneumonia, uveitis, severe sepsis, acute renal failure and was euthanized. The mixed neuropathy resulted in rapid clinical deterioration of the animal, due to the difficulty in swallowing and consequent associated respiratory processes. This report emphasizes the importance of evaluating stylopharyngeus muscle origin in cases of nasopharyngeal collapse associated with dysphagia in horses, given the possibility that structural changes in this muscle can result in laryngeal neuropathy.

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 agreement between subjective and objective evaluation methods was studied to identify claudication in the pelvic limbs of horses before and after flexion tests were performed. Twenty-nine horses were equipped with a wireless system of inertial sensors and evaluated during seven times while trotting. Videos were recorded to be evaluated by three veterinarians, with different levels of experience, to evaluate the agreement between the two different methods and between the evaluators. The evaluators and the objective evaluation had a low rate of agreement, with the exception of moderate agreement between the objective evaluation and evaluator 1 to identify lameness after the left total flexion and moderate agreement in evaluating the response to the tests, between objective evaluation and evaluator 2, after right distal flexion. This shows that there was a low agreement among the evaluators and between them and the objective evaluation for identifying lameness, measuring the degree of lameness and the response to the flexion tests.

The occurrence and distribution of antibodies against Sarcocystis neurona, Neospora caninum and Toxoplasma gondii was investigated in horses, dogs and cats from Curitiba, Paraná state, Brazil. Serum samples were selected from 100 horses, 100 dogs and 100 cats from the routine of the Veterinary Clinical Pathology Laboratory in the Veterinary Hospital of the University of Paraná (UFPR). The 100 dog samples were divided into two groups: 35 samples from dogs with neurological sign (convulsion) and 65 samples from dogs without neurological signs. The animals were adults of different breeds, males and females. Samples were analyzed by indirect fluorescent antibody test (IFAT) for protozoa S. neurona, N. caninum and T. gondii at the following cut-off dilutions: horses: 1:50, 1:50 and 1:16; dogs: 1:50, 1:50 and 1:16; cats: 1:50, 1:50 and 1:50, respectively. The obtained results were 42% of horses, 7% of dogs and 5% of cats seropositive for S. neurona; 58% of horses, 68% of dogs and 42% of cats seropositive to N. caninum, and 36% of horses, 20% of dogs and 21% of cats seropositive for T. gondii. Among the dogs with neurological signs, 8.6%, 68.6% and 25.7% were seropositive for S. neurona, N. caninum and T. gondii, respectively. Among the dogs without neurological signs, 6.2% 67.7% and 16.9% were seropositive for S. neurona, N. caninum and T. gondii, respectively. No statistical difference was found between groups of seropositive dogs for the three protozoa with neurological signs and without neurological signs. Co-infection and high antibody titers were detected. The antibodies against Sarcocystis neurona, Neospora caninum and Toxoplasma gondii were found widely distributed among horses, dogs and cats in the region of Curitiba, state of Paraná, Brazil.

Tis study evaluated the presence of Neospora caninum and Toxoplasma gondii antibodies in 320 domestic dogs living in urban and rural areas of the municipality of Poconé, located in the Pantanal wetlands of the state of Mato Grosso, Brazil. Anti-N. caninum (cut-of point 50) and anti-T. gondii (cut-of point 16) antibodies were detected by means of immunofuorescence assays (IFA), using NC-Bahia and RH strains as antigens, respectively. Anti-N. caninum antibodies were detected in 69 (21.56%; 95% CI: 17.27%-26.56%) dogs, 31 (44.93%) of which lived in urban areas and 38 (55.07%) in rural areas, and endpoint titers ranged from 50 to 3200. Anti-T. gondii antibodies were found in 132 (41.25%; 95% CI: 35.84%-46.87%) dogs, 58 (43.94%) from urban areas and 74 (56.06%) from rural areas, and endpoint titers ranged from 16 to 8192. A total of 33 dogs (10.3%) (12 urban and 21 rural animals) reacted to both agents (P <0.05). Tis study showed a higher prevalence of anti-T. gondii compared to anti-N. caninum antibodies in the dogs living in the Pantanal region, suggesting that both protozoans circulate in the studied region. Tis information is relevant, in view of its implications for animal and public health.

The heart of a domestic swine is similar to that of a human regarding anatomy, blood perfusion, and distribution of nurturing arteries. In addition to the similarities, its low cost compared with other species is also one of the reasons these animals have been increasingly used in medical schools and in clinical, surgical, and pharmacological studies. Therefore, we aimed to identify the origin and distribution of the right and left coronary arteries of boars, emphasizing the configuration and macroscopic representativity of their branches while characterizing a possible dominance concerning the type of circulation and the potential use of this animal as an experimental model, hence boars are the ancestors of the domestic pigs. The left coronary artery has bifurcated into paraconal interventricular branch and circumflex branch; or it has trifurcated into paraconal interventricular branch, the oblique branch, and into the left circumflex branch. The right coronary artery has originated the marginal branches to the right ventricle and the right circumflex branch, which has branched out in the subsinuous interventricular branch. Anastomoses have stood out among the paraconal and subsinuous interventricular branches – where a right dominant coronary artery occurred – and between the right and left circumflex branches. We concluded that the morphology and the distribution of the coronary arteries of boars resemble those of a human and, thus, our results are useful for the conception of experimental hemodynamics and possible use as process models.

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.

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.
