Enucleação subconjuntival em um gavião / Subconjuntival enucleation in a Hawk

O gavião-asa-de-telha (Parabuteo unicinctus) é uma ave de rapina que possui ampla distribuição em todo o território nacional. As aves de rapina desenvolveram uma visão tão eficiente que as puseram num patamar diferenciado em relação às outras espécies. No entanto, isso as tornou extremamente sensíveis às afecções oftálmicas, como malformações, inflamações, infecções, degenerações, neoplasias, distúrbios nutricionais e lesões traumáticas. Diante disso, este trabalho apresenta um relato de caso que descreve um gavião-asa-de-telha (Parabuteo unicinctus) adulto, fêmea, pesando 0,800kg, cujo a principal queixa é o olho esquerdo buftálmico e com coloração acinzentada. Este quadro clínico suscitou na remoção do olho pela técnica de enucleação subconjuntival lateral, sendo essa manobra a única forma de interromper o estímulo doloroso e a infecção. Por conseguinte, o trabalho demonstrou a importância e a exequibilidade da técnica correta de enucleação em aves de rapina, de modo a permitir a manutenção da espécie e minimizar os riscos de extinção.

The Harris' hawk (Parabuteo unicinctus) is a bird of prey that has a wide distribution throughout the national territory. Birds of prey have developed such an efficient vision that they are on a different level compared to other species. However, it made them extremely sensitive to ophthalmic conditions, such as malformations, inflammations, infections, degenerations, neoplasms, nutritional disorders, and traumatic injuries. Thus, this work presents a case report that describes an adult female Harris' hawk (Parabuteo unicinctus), weighing 0.800kg, whose main complaint is the left eye buphthalmic and with a grayish color. This clinical condition led to the removal of the eye by the lateral subconjunctival enucleation technique, which was the only way to interrupt the painful stimulus and the infection. Therefore, the work demonstrated the importance and feasibility of the correct technique of enucleation in birds of prey to allow the maintenance of the species and minimize the risks of extinction.

Pseudopterígio em coelho - tratamento com tracolimus / Pseudopterygium in a rabbit - treatment with tracolimus

Background: Pseudopterygium, also known as aberrant conjunctival growth, is poorly described in the literature, althoughit is known that this abnormality is uncommon and affects dwarf rabbits and their crossbreeds. The etiology of this diseaseis unknown, but there are hypotheses that the conjunctival growth cause may have its origins in immunological factors,inflammation, traumatic conditions, or cartilage dysplasias. Thus, this study reports the treatment efficacy applied in arabbit, through the continuous use of tracolimus eye drops, after surgical procedure of conjunctival fold resection, as away of controlling the pseudopterygium in rabbits.Case: This case report discusses the positive results from the surgical and therapeutic conduct of a clinical case attended bythe Ophthalmology and Microsurgical Veterinary Service at the Hospital Veterinário Universitário (HVU) of the UFSM. Thepatient was a male rabbit, sterilized, approximately 2-year-old, crossed with a dwarf rabbit. The owner’s main complaintwas the change in the aspect of the left eye, with progressive worsening in the previous four weeks. In the ophthalmologicalexamination, the animal did not present impaired vision or discomfort, however, a vascularized pink membrane was noted,which consisted of a fold of the bulbar conjunctiva, that grew centripetally and covered 90% of the cornea in 360 degrees.The diagnosis was confirmed through visual inspection and the patient’s history. The eye alteration had a characteristicaspect, described as proliferation of the bulbar conjunctiva over the cornea, in a centripetal manner and without signs ofinflammation. In addition, other ophthalmological alterations were ruled out during the patient’s physical and specificexamination. The patient was referred for anesthetic evaluation and, in addition, pre-surgical blood tests were performed,which were normal, according to the expected ranges for the species...

Innate immunity gene expression profiles in conjunctival membrane biopsies from Amazonian buffalo / Perfis de expressão de genes da imunidade inata em biopsias de membrana conjuntival de búfalos da Amazônia

Domestic buffalo production plays an economically important role in the Brazilian Amazon, but they are susceptible to many diseases favored by the tropical climate and annually flooded habitats, including ocular diseases. In this context, it is important to select genotypes that maximize innate ocular immunity in Amazonian herds. We aimed to characterise, for the first time, gene expression profiles of the innate immune system in the conjunctival membrane of buffalo. Ocular conjunctival tissue samples were collected from 60 clinically healthy slaughtered animals in the northern Brazilian state of Amapá. The samples were histologically processed for classification into three groups according to the quantitative degree of lymphoid tissue associated with the conjunctiva (discrete, G1; slight, G2; and moderate, G3 presence of lymphoid tissue). RT-PCR was used to quantify gene expression of inflammatory cytokine (IL6, IL10, TNFA, IFNG), Toll-like receptor 4 (TLR4), and Defensin beta 110 (DEFB110), relative to the endogenous GAPDH gene. G1 animals presented low expression for IL6, IL10, TNFA, and DEFB110, while G2 exhibited high expression for IL6, IL10, IFNG, and TLR4. All G3 animals showed high expression for all tested genes. These results suggest a greater resistance to pathogenic microorganisms of buffalos in the G3 group, and the proportion of lymphoid tissue associated with the conjunctiva may be related to the immune resistance of individuals.(AU)

A produção de búfalos domésticos desempenha um papel economicamente importante na Amazônia brasileira, mas eles são suscetíveis a muitas doenças favorecidas pelo clima tropical e habitats inundados anualmente, incluindo doenças oculares. Nesse contexto, é importante selecionar genótipos que maximizem a imunidade ocular inata em rebanhos amazônicos. Objetivamos caracterizar, pela primeira vez, perfis de expressão gênica do sistema imune inato na membrana conjuntival de búfalos. Amostras de tecido conjuntival ocular foram coletadas de 60 animais clinicamente saudáveis abatidos no estado do Amapá, norte do Brasil. As amostras foram processadas histologicamente para classificação em três grupos de acordo com o grau quantitativo de tecido linfoide associado à conjuntiva (discreta, G1; leve, G2; e moderada, G3 presença de tecido linfoide). RT-PCR foi utilizado para quantificar a expressão gênica de citocinas inflamatórias (IL6, IL10, TNFA, IFNG), receptor Toll-like 4 (TLR4) e Defensina beta 110 (DEFB110), em relação ao gene GAPDH endógeno. Os animais do G1 apresentaram baixa expressão para IL6, IL10, TNFA e DEFB110, enquanto G2 exibiu alta expressão para IL6, IL10, IFNG e TLR4. Todos os animais do G3 apresentaram alta expressão para todos os genes testados. Esses resultados sugerem maior resistência aos microrganismos patogênicos dos búfalos do grupo G3, e a proporção de tecido linfoide associado à conjuntiva pode estar relacionada à resistência imunológica dos indivíduos.(AU)

Polymerase chain reaction using conjunctival swab samples for detecting Leishmania DNA in dogs / Reação em cadeia da polimerase usando amostras de Swab de conjuntiva para detecção de DNA de Leishmania em cães

Abstract The dog is the main domestic reservoir of Leishmania and font of infection for the vector, constituting an important host for the transmission of the parasite to humans. Non-invasive collection of swab samples for leishmaniasis diagnosis has been a promising alternative. This study analyzed the positivity of polymerase chain reaction (PCR) for the diagnosis of canine leishmaniasis in conjunctiva samples. DNA extraction was performed using SDS 20% and PCR was performed using 13A/13B primers that amplify 120-bp of Leishmania kDNA. Of the 77 dogs analyzed, 50 (64.93%) had ocular changes: 25 (32.47%) dogs had periocular lesion, 41 (53.25%) dogs had purulent eye discharge, and 17 (22.08%) dogs had both signals. PCR was positive in 35 dogs (45.45%), and there was no significant difference between dogs with and without ocular signals (p=0.4074). PCR positivity was significant higher in dogs without periocular injury (p=0.0018). Conjunctive PCR, a less invasive, fast, and painless collection technique, is indicated to complement the diagnosis, especially in dogs without periocular injury, independent of the presence of purulent eye discharge.

Dos 77 cães analisados, 50 (64,93%) tiveram alterações oculares; 25 (32,47%) cães tiveram uma lesão periocular; 41 (53,25%) tiveram secreção ocular purulenta e 17 (22,08%) cães tiveram ambos os sinais. A PCR foi positiva em 35 cães (45,45%) e não houve diferença significativa em cães com e sem sinais oculares (p = 0,4074). A positividade da PCR foi significativamente maior em cães sem lesão periocular (p = 0,0018). PCR em conjuntiva, uma técnica de coleta menos invasiva, rápida e indolor, é indicada para complementar o diagnóstico, principalmente em cães sem lesão periocular, independentemente da presença de secreção ocular purulenta.

Ocular and oral lesions caused by Tacinga inamoena in sheep and goats in Northeast Brazil

ABSTRACT: Two outbreaks of traumatic injuries in goats and sheep associated with grazing and ingestion of the cactus Tacinga inamoena have recently been reported in the state of Paraíba, Brazil. In the first of these, which was detected in 2019 during a preliminary inspection of a herd of 70 animals, it was found that 15 showed certain ocular complications, and these animals were subjected to general physical and ophthalmic examinations. The clinical findings included excessive lacrimation, blepharitis, photophobia, corneal opacity, hyphema, corneal neovascularization, corneal ulcers, and adherence of gloquids to the bulbar conjunctiva and cornea. Large amounts of T. inamoena were found to be present in several areas in which these animals had been grazed and had been observed consuming the fruits of this plant. In the second outbreak during the following year, two sheep from a total of 100 animals were identified as having oral lesions associated with grazing in areas within which T. inamoena was growing. One of these animals was referred to a veterinary hospital, and on physical examination was found to show apathy, anorexia, a body score of 1.5, and the presence of gloquids within the fur. With respect to the oral cavity, halitosis, severe sialorrhea, extensive hemorrhagic ulcers, and painful tenderness on palpation were detected. Given the unfavorable prognosis, the sheep was subsequently euthanized. At necropsy, multifocal to coalescent plaques were detected on the upper and lower lips, oral mucosa, tongue, and hard and soft palates. These were generally elevated and firm and characterized by an irregular, ulcerated surface, sometimes crusty, with a yellow to light brown center and erythematous edges. The findings of this study highlight that the consumption of T. inamoena can cause serious oral and ophthalmic lesions in small ruminants in the northeastern semi-arid regions of Brazil, and can potentially contribute to substantial large economic losses. This problem tends to be exacerbated by the invasive behavior of T. Inamoena, particularly in areas in the process of environmental degradation.

RESUMO: Relatam-se dois surtos de lesões traumáticas associadas ao pastejo e ingestão da Tacinga inamoena por caprinos e ovinos no estado da Paraíba, Brasil. No primeiro surto observou-se durante uma inspeção preliminar do rebanho que 15 dos 70 animais apresentavam alterações oculares, os animais foram submetidos ao exame físico geral e ao exame oftálmico. Lacrimejamento excessivo, blefarite, fotofobia, opacidade de córnea, hifema, neovascularização corneana, úlceras de córnea e gloquídeos aderidos à conjuntiva bulbar e córnea foram os achados clínicos identificados. A planta estava presente em diversas áreas e em grande quantidade nas áreas de pastejo, onde os animais eram vistos ingerindo seus frutos. No segundo surto, dois ovinos de um total de 100 animais, foram identificados com lesões orais associadas ao pastejo em áreas da planta. Um deles foi encaminhado ao Hospital Veterinário. No exame físico, o animal apresentou apatia, anorexia, escore corporal 1,5, pelos opacos, eriçados e no pelame era possível identificar gloquídeos. Na cavidade oral observou-se halitose, sialorreia intensa, extensas úlceras hemorrágicas e sensibilidade dolorosa à palpação. Devido ao prognóstico desfavorável o animal foi eutanasiado. Na necropsia, placas multifocais a coalescentes, elevadas, firmes e com superfície irregular, ulcerada, por vezes crostosas, com centro amarelo a marrom-claro e bordos eritematosos, estavam presentes nos lábios superiores, inferiores, mucosa oral, língua, palatos duro e mole. T. inamoena causa sérias lesões orais e oftálmicas em pequenos ruminantes no semiárido nordestino e prejuízos econômicos de grandes dimensões, que podem ser agravados pelo comportamento invasor da T. inamoena em áreas com indícios de degradação ambiental.

Ocular lesions in a domestic feline: a closer look at the fungal pathogen Sporothrix brasiliensis / Lesões oculares em um felino doméstico: um olhar atento ao patógeno fúngico Sporothrix brasiliensis

Sporotrichosis is a dermatozoonosis, caused by dimorphic pathogenic fungi of the genus Sporothrix. Although Sporothrix brasiliensis is the most frequent and pathogenic species identified from the Brazilian sporotrichosis hyperendemic, to the best of our knowledge this is the first report of its molecular diagnosis from a cat with ocular lesions. A 3-month-old female, domestic feline presented an ocular manifestation with granuloma in the lower-left palpebral conjunctiva, in addition to mucocutaneous lesions in varied locations throughout the body. Samples were collected for subsequent cytopathology, fungal culture, serology, and molecular genotyping. Itraconazole was prescribed for the treatment of sporotrichosis and the animal was considered clinically cured at the end of 5 months of treatment and discharged. S. brasiliensis-cat interactions can manifest with a multitude of clinical forms that resemble either infectious or noninfectious diseases. Both the need for meticulous cat physical evaluation by a veterinarian followed by accurate laboratory diagnosis are key Public Health measures in the Brazilian sporotrichosis hyperendemic area.(AU)

A esporotricose é uma dermatozoonose causada por fungos patogênicos dimórficos do gênero Sporothrix. Embora o Sporothrix brasiliensis seja a espécie mais patogênica e prevalente na hiperendemia brasileira de esporotricose, segundo nosso conhecimento este é o primeiro relato de um gato com lesões oculares causadas por esta espécie, via diagnóstico molecular. Um felino doméstico com três meses de idade apresentou manifestação ocular com granuloma em conjuntiva palpebral inferior esquerda, além de lesões mucocutâneas em diferentes áreas do corpo. Amostras foram coletadas para posterior citopatologia, cultura de fungos, sorologia e genotipagem molecular. O itraconazol foi prescrito para o tratamento da esporotricose e o animal foi considerado clinicamente curado ao final de cinco meses de tratamento, recebendo alta. As interações do S. brasiliensis com o gato podem se manifestar com uma infinidade de formas clínicas que se assemelham a doenças infecciosas ou não. A necessidade de avaliação física meticulosa desses animais por um médico veterinário, seguida do diagnóstico laboratorial preciso, são medidas essenciais em saúde pública na área hiperendêmica para a esporotricose no Brasil.(AU)

Ocular and oral lesions caused by Tacinga inamoena in sheep and goats in Northeast Brazil / Lesões oculares e orais causadas por Tacinga inamoena em ovinos e caprinos no Nordeste brasileiro

Two outbreaks of traumatic injuries in goats and sheep associated with grazing and ingestion of the cactus Tacinga inamoena have recently been reported in the state of Paraíba, Brazil. In the first of these, which was detected in 2019 during a preliminary inspection of a herd of 70 animals, it was found that 15 showed certain ocular complications, and these animals were subjected to general physical and ophthalmic examinations. The clinical findings included excessive lacrimation, blepharitis, photophobia, corneal opacity, hyphema, corneal neovascularization, corneal ulcers, and adherence of gloquids to the bulbar conjunctiva and cornea. Large amounts of T. inamoena were found to be present in several areas in which these animals had been grazed and had been observed consuming the fruits of this plant. In the second outbreak during the following year, two sheep from a total of 100 animals were identified as having oral lesions associated with grazing in areas within which T. inamoena was growing. One of these animals was referred to a veterinary hospital, and on physical examination was found to show apathy, anorexia, a body score of 1.5, and the presence of gloquids within the fur. With respect to the oral cavity, halitosis, severe sialorrhea, extensive hemorrhagic ulcers, and painful tenderness on palpation were detected. Given the unfavorable prognosis, the sheep was subsequently euthanized. At necropsy, multifocal to coalescent plaques were detected on the upper and lower lips, oral mucosa, tongue, and hard and soft palates. These were generally elevated and firm and characterized by an irregular, ulcerated surface, sometimes crusty, with a yellow to light brown center and erythematous edges. The findings of this study highlight that the consumption of T. inamoena can cause serious oral and ophthalmic lesions in small ruminants in the northeastern semi-arid regions of Brazil, and can potentially contribute to substantial large economic losses. This problem tends to be exacerbated by the invasive behavior of T. Inamoena, particularly in areas in the process of environmental degradation.(AU)

Relatam-se dois surtos de lesões traumáticas associadas ao pastejo e ingestão da Tacinga inamoena por caprinos e ovinos no estado da Paraíba, Brasil. No primeiro surto observou-se durante uma inspeção preliminar do rebanho que 15 dos 70 animais apresentavam alterações oculares, os animais foram submetidos ao exame físico geral e ao exame oftálmico. Lacrimejamento excessivo, blefarite, fotofobia, opacidade de córnea, hifema, neovascularização corneana, úlceras de córnea e gloquídeos aderidos à conjuntiva bulbar e córnea foram os achados clínicos identificados. A planta estava presente em diversas áreas e em grande quantidade nas áreas de pastejo, onde os animais eram vistos ingerindo seus frutos. No segundo surto, dois ovinos de um total de 100 animais, foram identificados com lesões orais associadas ao pastejo em áreas da planta. Um deles foi encaminhado ao Hospital Veterinário. No exame físico, o animal apresentou apatia, anorexia, escore corporal 1,5, pelos opacos, eriçados e no pelame era possível identificar gloquídeos. Na cavidade oral observou-se halitose, sialorreia intensa, extensas úlceras hemorrágicas e sensibilidade dolorosa à palpação. Devido ao prognóstico desfavorável o animal foi eutanasiado. Na necropsia, placas multifocais a coalescentes, elevadas, firmes e com superfície irregular, ulcerada, por vezes crostosas, com centro amarelo a marrom-claro e bordos eritematosos, estavam presentes nos lábios superiores, inferiores, mucosa oral, língua, palatos duro e mole. T. inamoena causa sérias lesões orais e oftálmicas em pequenos ruminantes no semiárido nordestino e prejuízos econômicos de grandes dimensões, que podem ser agravados pelo comportamento invasor da T. inamoena em áreas com indícios de degradação ambiental.(AU)

Investigation of Feline calicivirus infection in cats with upper respiratory tract disease in Diyarbakir, Turkey / Investigação de infecção por calicivírus felino em gatos com doença do trato respiratório superior na região de Diyarbakir, Turquia

Feline calicivirus is among the most common pathogenic microorganisms in upper respiratory tract disease (URTD) and oral lesions of cats. It leads to stomatitis, oral ulceration, ocular and nasal discharge, conjunctivitis, fever, lameness, anorexia, hypersalivation, pneumonia, respiratory distress, coughing, and depression in infected cats. This study aimed to determine the role of Feline calicivirus (FCV) in cats with the upper respiratory tract disease in the Diyarbakir region, Turkey, to provide treatment for infected cats and contribute to the disease prophylaxis. The study material consisted of 10 cats (control group) considered to be healthy according to the clinical examination and 20 cats with URTD that were not vaccinated against Feline calicivirus infection of different breeds, ages, and genders brought to Dicle University Veterinary Faculty Prof. Dr. Servet SEKIN Polyclinic with URTD. After routine clinical examinations of the animals, oral and conjunctival swabs and blood samples were taken. Hematological and biochemical analyzes of blood samples were performed. Swab samples were analyzed by the polymerase chain reaction (PCR) method for the diagnosis of the agent. Oral lesions, hypersalivation, ocular and nasal discharge, coughing, and breathing difficulties were seen in clinical examinations of cats with URTD. Feline calicivirus was detected in only one cat's conjunctival swab sample in PCR analyses. As a result, we found that Feline calicivirus infection was present in cats with URTD in the Diyarbakir region, and 5% positivity was found in cats with clinical symptoms according to PCR analysis.(AU)

Análises hematológicas e bioquímicas das amostras de sangue foram realizadas e os swabs foram analisados pelo método da reação em cadeia pela polimerase (PCR) para diagnóstico do agente. Nos gatos infectados foram constatadas: lesões orais, hipersalivação, descargas oculares e nasais, tosse e dificuldade respiratória. O calicivírus felino foi detectado pela técnica de PCR no swab conjuntival de apenas um gato. A conclusão obtida foi que a infecção pelo calicivírus felino foi detectada pela técnica de PCR na região de Diyarbakir, Turquia, em gatos com doença do trato respiratório superior com a frequência de 5%.(AU)

Eversão da cartilagem da terceira pálpebra em um gato / Eversion of the third eyelid cartilage in a cat

Background: Eversion of the cartilage of the third eyelid is a rare congenital disease in cats. It is caused by the anterioreversion of the cartilage edge of the third eyelid. Clinical signs may be associated with secondary keratoconjunctivitis,third eyelid gland protrusion, and ocular surface irritation. The diagnosis is made by ophthalmic examination, and treatment consists of surgical resection of the everted cartilage portion. The goal of the present study was to report a case ofeversion of third eyelid cartilage in a cat, given that it is an unusual abnormality in this animal species, and an importantdifferential diagnosis to be considered in the disorders of the third eyelid.Case: A 6-year-old neutered female Persian cat was presented with a presumptive diagnosis of protrusion of the thirdeyelid gland, history of ocular irritation, and epiphora in the left eye. The disorder had been intermittently present sincethe animal was 1-year-old, with spontaneous disappearance after approximately 15 days. The owner related the reappearance of the disorder to stressful situations, with no previous history of trauma or other ocular alteration. During theophthalmic examination, suspended solute was observed through biomiscroscopic examination in both eyes, as well asan increase in volume of the third eyelid in the left eye, without other changes. A thorough examination, under generalanesthesia, indicated the protruding volume of the cartilage of the everted third eyelid. The third eyelid was pleated inits upper portion, demonstrating that the cartilage of the third eyelid was folded instead of following the curvature of theocular surface. Under general anesthesia, the cartilage was partially removed through two parallel incisions on the bulbarconjunctival surface, divulsioning 5 mm in length in the vertical portion of the cartilage in a ‘T’ shape, and separating the...

Carcinoma de células escamosas multicêntrico com envolvimento de anexos oculares em um cão / Multicentric squamous cell carcinoma with the involvement of the ocular annexes in a dog

Background: The cutaneous squamous cell carcinoma (cSCC) is considered to be a frequent neoplasm in dogs, however,its origin in ocular annexes, especially in relation to the conjuctival location, is a rare finding in dogs. Therefore, it wasaimed to report the occurrence of a multicentric SCC, with the involvement of ocular annexes in a dog, emphasizing itsclinical characteristics and histopathological findings.Case: A 6-year-old non-castrated white-coated Pitbull dog was attended, with a history of increased volume and bloodysecretion in the left eye, with an evolution of approximately six months. By means of general physical examination, ulcerated lesions in the foreskin and scrotum were found. During the ophthalmologic examination was identified an extensiveand irregular exophytic mass, of a reddish color and with a cauliflower-like appearance, located in the inferior bulbarconjunctiva and third eyelid of the left eye, accompanied by a large quantity of piosanguinolenta secretion, mainly duringmanipulation. Other alterations were observed, such as, meibomitis, conjuctival hyperemia, hypopyon, corneal edema andloss of sight. In the right eye, the only alteration found was conjunctival hyperemia. The hemograma revealed discreetanemia; the serum biochemical profile was inside the normal range and there was no evidence of metastasis in the imaging examinations. The animal was submitted to the incisional biopsy of the lesions for histopathological analysis, whichrevealed a proliferation of neoplastic epithelial cells, highly pleomorphic, composed of eosinophilic cytoplasm, whichvaried from scarce to moderate, of indistinct borders, with a large nucleus and loose chromatin and large and evidentnucleolus, compatible with SCC, enabling, also, the classification as multicentric...

Serological study of feline leishmaniasis and molecular detection of Leishmania infantum and Leishmania braziliensis in cats (Felis catus) / Pesquisa sorológica da leishmaniose felina e detecção molecular de Leishmania infantum e Leishmania braziliensis em gatos (Felis catus)

Blood samples and swabs from ocular conjunctiva and mouth were obtained from 64 cats. Of 64 serum samples, 19 were positive for Leishmania antibodies by ELISA (29.80%). Eight cats were positive by PCR (12.5%) in swab samples from mouth and/or ocular mucosa. Poor kappa agreement between serological and molecular results (k = 0.16) was obtained. From five positive PCR samples one was L. braziliensis and four were L. infantum. Phylogenetic analysis performed with the five isolates of Leishmania, showed that samples of L. infantum isolated from the cats were phylogenetically close to those isolated from domestic dogs in Brazil, while the L. braziliensis is very similar to the one described in humans in Venezuela. The study demonstrated that, despite high seropositivity for Leishmania in cats living in the study region, poor agreement between serological and molecular results indicate that positive serology is not indicative of Leishmania infection in cats. Parasite DNA can be detected in ocular conjunctiva and oral swabs from cats, indicating that such samples could be used for diagnosis. Results of phylogenetic analyzes show that L. infantum circulating in Brazil is capable of infecting different hosts, demonstrating the parasite's ability to overcome the interspecies barrier.(AU)

Amostras de sangue e swabs da conjuntiva ocular e oral foram obtidas de 64 gatos. Das 64 amostras de soro, 19 foram positivas para anticorpos contra Leishmania por ELISA (29,80%). Oito gatos foram positivos por PCR (12,5%) em amostras de swab da boca e / ou mucosa ocular. Demonstrou-se baixa concordância kappa entre os resultados sorológicos e moleculares (k = 0,16). Das cinco amostras positivas para PCR, uma era L. braziliensis e quatro eram L infantum. A análise filogenética realizada com os cinco isolados de Leishmania, mostrou que amostras de L. infantum, isoladas dos gatos, eram filogeneticamente próximas às isoladas de cães domésticos do Brasil enquanto L. braziliensis era muito semelhante ao descrito em humanos na Venezuela. O estudo demonstrou que, apesar da alta soropositividade para Leishmania, em gatos que vivem na região do estudo, pouca concordância entre os resultados sorológicos e moleculares indica que a sorologia positiva não é indicativa de infecção por Leishmania em gatos. O DNA do parasita pode ser detectado na conjuntiva ocular e nas zaragatoas orais de gatos, indicando que essas amostras podem ser usadas para o diagnóstico. . Resultados de análises filogenéticas mostram que L. infantum, circulando no Brasil, é capaz de infectar diferentes hospedeiros, demonstrando a capacidade do parasita de superar a barreira interespécies.(AU)

Impacto do grau de uveíte em diferentes tipos de úlceras de córneas em cães submetidos ao enxerto pediculado de conjuntiva bulbar - 34 casos / Impact of uveitis score on different types of corneal ulcers in dogs subjected to the bulbar conjunctival pedicle graft - 34 cases

O presente trabalho objetivou avaliar os resultados de 34 olhos submetidos ao enxerto conjuntival pediculado (ECP) em ceratites ulcerativas profundas (n=5), em ceratites ulcerativas com colagenólise (n=2), descemetocele (n=7), perfuração corneal (n=15) e prolapso de íris (n=5). Os impactos do grau de uveíte e da integridade da córnea foram correlacionados com presença e ausência de visão por tabelas de contingência. Raças braquicefálicas foram acometidas em 91,11% dos casos. O número de córneas consideradas perfuradas [20/34 (58,82%)] foi maior que o de córneas íntegras [14/34 (41,17%)]. Ao 50º dia de pós-operatório, o número de olhos visuais que apresentavam córneas íntegras previamente às cirurgias (n=13) não diferiu significativamente dos olhos com córneas perfuradas (n=12) (P=0,05). Avaliações relativas ao grau de uveíte, revelaram que a metade dos casos foi considerada severa [17/34 (50%)] e na outra metade as uveítes foram consideradas discretas. Dos 17 casos que apresentaram uveíte severa, oito recuperaram a visão. Já nos 17 olhos onde a uveíte foi considerada leve, 15 mantiveram a visão ao final do período de avaliação. Apesar de a integridade da córnea não se correlacionar com a severidade da uveíte (P=0,48), constatou-se que o número de olhos visuais com uveíte discreta foi significativamente maior que os olhos com uveíte severa (P=0,006). Neste estudo, a taxa geral de sucesso visual após ECP foi de 73,52% e a integridade da córnea não exerceu impacto significativo sobre a manutenção da visão. Todavia, olhos acometidos por uveítes severas apresentaram menor chance de recuperar a visão.(AU)

The present study aimed to evaluate the results of 34 eyes of dogs presenting deep corneal ulcer (n=5), colagenolytic corneal ulcer (n=2), descemetocele (n=7), corneal perforation (n=15), and iris prolapse (n=5) that were corrected by the bulbar conjuntival pedicle graft (CPG). The uveitis score and the corneal integrity were correlated with the presence or absence of vision by contingency tables. Brachycephalic breeds accounted for 91.11% of all cases. The number of perforated corneas [20/34 (58.82%)] were higher than the non-perforated ones [14/34 (41.17%)]. At post-operative day 50, the number of visual eyes with non-perforated corneas before surgery (n=13) did not differ significantly from the eyes with perforated corneas (n=12) (P = 0.05). In half of the cases, uveitis score was considered severe [17/34 (50%)], and in the other half, mild. Eight out of 17 eyes classified with severe uveitis regained vision. In 17 eyes where uveitis score was considered mild, 16 regained vision at the end of the study. Although corneal integrity was non-correlated with the uveitis score (P = 0.48), the number of visual eyes scored with mild uveitis were significantly larger than the eyes with severe uveitis (P = 0.006). In this study, the overall success visual rate after CPG was 73,52% % and the corneal integrity did not play an important role regarding maintenance of vision. However, eyes presenting severe uveitis score had less chance to regain vision.(AU)
