ABSTRACT

Ingestion of metallic and/or sharp foreign bodies triggers cases of traumatic reticuloperitonitis and its sequelae in cattle. Among these sequelae, we can highlight traumatic reticulosplenitis, that has high mortality, although its frequency in the ruminant medicine is low. Therefore, based on the scarcity of information on this disease, the current study aimed to evaluate the clinical, laboratory, ultrasonographic, and pathological findings of 30 adult cattle diagnosed with traumatic reticulosplenitis. Clinical, ultrasound, and anatomopathological findings were analyzed using descriptive statistics and laboratory data were evaluated using measures of central tendency. Clinically the animals presented dehydration and alterations in behavior, appetite, and ruminal motility. Hematological findings revealed neutrophilic leukocytosis (37077.17±25004.59cell/µL) with regenerative left shift and hyperfibrinogenemia (1130±364.98mg/dL). The ultrasound examination enabled visualization of mobile and echogenic filaments that corresponded to the presence of fibrin adhesions. Displacement of the reticulum and irregularity in its contour, as well as alterations in the quantity, pattern, and amplitude of reticular contractions were also observed. Splenic alterations such as abscesses were found, characterized as circular structures of varying sizes delimited by capsules containing variable echogenicity. Splenic vein thrombosis and spleen folding were also observed. The results obtained in the current study indicated that traumatic reticulosplenitis causes nonspecific clinical signs, severe laboratory alterations and, mainly, that ultrasound is an efficient method for the diagnosis of this disease, since the anatomopathological lesions confirmed the ultrasound findings.(AU)


A ingestão de corpos estranho de origem metálica e/ou pontiagudos desencadeia em bovinos, quadros de Reticuloperitonite Traumática e suas sequelas. Dentre as quais podemos destacar a retículo esplenite traumática cuja letalidade é elevada, embora a mesma apresente uma baixa frequência na clínica de ruminantes. Portanto, baseado na escassez de informações sobre esta enfermidade, este trabalho teve por objetivo avaliar os achados clínicos, laboratoriais, ultrassonográficos e anatomopatológicos de 30 bovinos adultos diagnosticados com retículo esplenite traumática. Os achados clínicos, ultrassonográfico e anatomopatológico foram analisados por meio de estatística descritiva, e os dados laboratoriais foram avaliados utilizando-se as medidas de tendência central. Clinicamente os animais apresentaram desidratação e alterações no comportamento, apetite e na motilidade ruminal. Os achados hematológicos revelaram leucocitose (37077.17±25004.59cell/µL) por neutrofilia com desvio à esquerda regenerativo e hiperfibrinogenemia (1130±364.98mg/dL). O exame ultrassonográfico possibilitou a visualização de filamentos móveis e ecogênicos que corresponderam à presença de aderências fibrinosas, observou-se também, deslocamento do retículo e irregularidade no seu contorno além das alterações na quantidade, padrão e amplitude das contrações reticulares. Permitiu ainda, a constatação de alterações esplênicas como abscessos que foram caracterizados como estruturas circulares de variados tamanhos delimitada por capsula contendo no seu interior conteúdo de ecogenicidade variável. Trombose da veia esplênica e dobramento do baço. Os resultados obtidos nesse trabalho, indicaram que a retículo esplenite traumática causa sinais clínicos inespecíficos, severas alterações laboratoriais e principalmente que a ultrassonografia é um método eficiente para o diagnóstico dessa enfermidade uma vez que as lesões anatomopatológicas confirmaram os achados ultrassonográficos.(AU)

ABSTRACT

An 11-year (2007-2018) survey of epidemiological, clinical and pathological findings of horses with primary gastric rupture (PGR) was conducted. Twenty horses presented PGR, nine (45%) horses were clinically evaluated, eleven (55%) were sent dead, and all animals were necropsied. PGR contributed to a prevalence of 0.31% (9/2,868) of all equid attendances, 1.83% (9/491) of colic cases, and 4.1% (20/487) of all equid necropsies. Highly fermentable feed (n=7), gastric impaction (n=4), and perforating gastric ulcer (n=1) were the main causes of PGR; whilst eight horses presented idiopathic gastric rupture. Clinically evaluated horses were tachycardic, tachypneic, febrile, dehydrated, with increased abdominal tension, abnormal mucous membranes and reduced to absent intestinal borborygmi. Improper dietary management, such as the ingestion of low-quality roughage and highly fermentable feedstuffs were detected as the main factors associated with PGR in Midwestern Brazil. It is important to raise awareness in horse owners about proper feed management to minimize PGR.(AU)


Foi realizado um levantamento de 11 anos (2007-2018) dos achados epidemiológicos, clínicos e patológicos de equinos com ruptura gástrica primária (RGP). Vinte equinos apresentaram RGP, dos quais nove (45%) foram avaliados clinicamente e 11 (55%) foram enviados mortos, sendo todos os animais necropsiados. A RGP contribuiu com prevalência de 0,31% de todos os atendimentos de equídeos (9/2.868), 1,83% (9/491) dos casos de cólica, e 4,1% (20/487) das necropsias em equídeos. Alimentos altamente fermentáveis (n=7), compactação gástrica (n=4) e perfuração de úlcera gástrica (n=1) foram as principais causas de RGP, enquanto oito equinos tiveram ruptura gástrica idiopática. Os equinos avaliados clinicamente apresentaram-se taquicárdicos, taquipneicos, febris, desidratados, com mucosas anormais, aumento da tensão abdominal e motilidade intestinal reduzida. O manejo inadequado da dieta, como a ingestão de forragens de baixa qualidade e alimentos altamente fermentáveis, foi o principal fator de risco associado à RGP no Centro-Oeste do Brasil. É importante aumentar a conscientização dos proprietários de equinos sobre o manejo alimentar adequado para minimizar a RGP.(AU)

ABSTRACT

The causes of death of cattle kept in pre-export feedlots (PEFs) and in feedlot for finishing for slaughter are described. Two studies were conducted: a retrospective study of mortality cases in feedlots from 2000 to 2017 registered at the "Laboratório Regional de Diagnóstico" of the "Faculdade de Veterinária" of the "Universidade Federal de Pelotas"; and a prospective study from January 2018 to August 2019, following up 22 feedlots for finishing and six PEFs for the export of live cattle. From January 2000 to August 2019 samples of 150 cases of diseases that affected feedlot cattle were received from 22 feedlots for finishing and 115 of the six PEFs followed. Mortality considering all diagnosed diseases was significantly higher in feedlots for finishing (p<0.05), than in PEFs for the export of live cattle, of 1% and 0.12%, respectively. Diseases of the digestive system were the most important causes, of death in feedlots regardless of its purpose. Acidosis presented the highest mortality rates both in feedlot for finishing (3.33%) as in PEFs for export (0.95%). In all cases the disease occurred due to failure in the adaptation of animals to the ingestion of concentrated foods. Bovine tick fever and pneumonia presented mortality rates of 0.13% and 0.09%, respectively in PEFs. In the feedlot for finishing seneciosis was the second cause of death due to cattle coming from areas with high infestation by the plant. In the present study, it was possible to identify the main diseases that occur in cattle feedlots for finishing or for the export of live animals in the southern region of Rio Grande do Sul. These diseases are known in other systems of cattle breeding and can be prevented or controlled through management, chemoprophylaxis or vaccination, minimizing losses due to mortality.(AU)


Descrevem-se as causas de morte de bovinos mantidos confinados em estabelecimentos pré-embarque (EPEs) para exportação de animais vivos e em estabelecimentos de terminação para abate. Foram realizados dois estudos: um retrospectivo dos casos de mortalidade em confinamentos de 2000 a 2017 registrados no Laboratório Regional de Diagnóstico da Faculdade de Veterinária da Universidade Federal de Pelotas; e um estudo prospectivo de janeiro de 2018 a agosto de 2019, acompanhando-se 22 confinamentos de terminação e seis EPEs para exportação de bovinos vivos. No total, de janeiro de 2000 a agosto de 2019 foram recebidos no LRD-UFPel amostras de 150 casos de enfermidades que afetaram bovinos confinados, 35 provenientes de 22 confinamentos de terminação e 115 dos seis EPEs acompanhados. A mortalidade considerando-se todas as enfermidades diagnosticadas foi significativamente maior nos confinamentos para terminação (p<0,05), do que nos EPEs para exportação de bovinos vivos, de 1% e 0,12%, respectivamente. As doenças do sistema digestivo foram as causas de morte mais importante nos confinamentos, independente da finalidade. Acidose apresentou as maiores taxas de mortalidade tanto nos confinamentos para terminação (3,33%) como nos EPEs para exportação (0,95%). Em todos os casos a doença ocorreu devido a falha na adaptação dos animais à ingestão de alimentos concentrados. Tristeza parasitária bovina e pneumonias apresentaram taxas de mortalidade de 0,13% e 0,09, respectivamente em EPEs de exportação. Nos confinamentos para terminação a seneciose foi a segunda causa de morte devido aos bovinos serem provenientes de áreas com alta infestação pela planta. Este estudo permitiu identificar as principais enfermidades diagnosticadas em confinamentos para terminação de bovinos ou para exportação de bovinos vivos na região Sul do Rio Grande do Sul. Observou-se que são doenças que ocorrem em outros sistemas de criação de bovinos e que podem ser prevenidas ou controladas por meio de manejo, quimioprofilaxia ou vacinação, minimizando prejuízos por mortalidade de animais.(AU)

ABSTRACT

Proventricular dilatation disease (PDD) is a lethal and important disease of captive psittacine birds, and affects a wide range of species, including endangered ones, and lacks an effective treatment. This report describes PDD in three blue-and-gold macaws (Ara ararauna) in southern Brazil. All three macaws originated from the same aviary and presented similar clinical signs including anorexia, apathy, emaciation and prostration. At necropsy, one of the macaws presented an enlarged proventriculus. Histologically, lymphoplasmacytic infiltrates was observed in the ganglia and nerves of the esophagus, crop, proventriculus, ventriculus, heart, adrenal glands, and adrenal medulla of all three cases. Two macaws had meningoencephalomyelitis and one had myocarditis. Immunohistochemistry identified PaBV antigen in the brain, proventricular, ventricular ganglia, and epicardial ganglia, and cardiomyocytes of all three macaws.(AU)


A doença da dilatação proventricular (PDD) e uma importante e fatal doença de psitacídeos de cativeiro, que afeta uma grande variedade de espécies e não tem um tratamento efetivo até o momento. Este relato descreve PDD em três araras canindé (Ara ararauna) no sul do Brasil. Todas as três araras eram provenientes do mesmo criatório e apresentaram sinais clínicos semelhantes incluindo anorexia, apatia, emaciação e prostração. Na necropsia, uma das araras apresentou proventrículo dilatado. No exame histopatológico, infiltrados linfoplasmacitários foram observados em gânglios e nervos do esôfago, inglúvio, proventrículo, moela, coração, glândulas adrenais e rins de todos os casos. Adicionalmente, meningoencefalomielite foi observada em duas araras e miocardite em uma. A imuno-histoquímica identificou antígenos de PaBV no encéfalo, coração, proventrículo e moela de todos os casos.(AU)

ABSTRACT

The objective of this study is to evaluate the ectoparasites and helminths of the white-crested elaenia, Elaenia albiceps chilensis. Feather mites Anisophyllodes elaeniae, Trouessartia elaeniae, and Analges sp. were detected in 51% of birds (n=106), whereas 24% were infected with lice (Tyranniphilopterus delicatulus, Menacanthus cfr. distinctus, and Ricinus cfr. invadens). Helminths Viguiera sp. and Capillaria sp. were found in five of the birds that were necropsied (n=20). With the exception of A. elaeniae, T. elaeniae, and T. delicatulus, all parasites represented new records found for the white-crested elaenia, and therefore for the Chilean repertoire of biodiversity.

ABSTRACT

The present study details the pathological and parasitological findings of parasitic ventriculitis and nematode infections in the large intestines of two female Rhea americana americana birds. The birds were housed in captivity, and both exhibited poor body condition and lethargy. The rheas were sent to the Veterinary Hospital of the Veterinary School, Universidade Federal de Minas Gerais (UFMG) and, despite medical care, the clinical condition of the birds did not improve. The birds died two days after admission, and were submitted to necropsy. Gross, histopathology and parasitological analysis resulted in the identification of Sicarius uncinipenis, which is associated with parasitic ventriculitis, while Deletrocephalus cesarpintoi was identified in the large intestine of both rheas. The apparent clinical indications, including loss of appetite and death, combined with the discovery of numerous parasites and other pathology changes, supported the conclusion that the death of the birds was caused by the parasitic infection. Further investigations of these infections in free-living and captive rheas are required, such that accurate data on the incidence and pathogenicity of these parasites can be obtained.


O presente estudo relata os achados patológicos e parasitológicos de ventriculite parasitária e da infecção por nematódeo no intestino grosso em duas fêmeas Rhea americana americana. As aves eram mantidas em cativeiro e ambas apresentaram condição corporal ruim e inapetência. As emas foram encaminhadas para o Hospital Veterinário da Escola de Veterinária da UFMG e, apesar dos cuidados médicos, não houve melhora na condição clínica. As aves morreram dois dias após a internação e foram encaminhadas para a necropsia. Ao exame macroscópico, histopatológico e parasitológico, Sicarius uncinipenis foi identificado e associado com ventriculite parasitária, enquanto Deletrocephalus cesarpintoi foi identificado no intestino grosso. Possivelmente, o quadro de inapetência e morte foi causado pela infecção parasitária, pois os parasitos eram numerosos. Mais investigações dessa infecção são necessárias em emas de vida livre e cativeiro, para a obtenção de informações mais precisas da incidência e patogenicidade desses parasitos.

ABSTRACT

Um surto de compactação primária de abomaso associada ao consumo de silagem de girassol ocorreu num rebanho bovino leiteiro do estado de Minas Gerais, do qual seis de 21 vacas secas em fase final de gestação e que recebiam silagem de girassol morreram. Os bovinos que adoeceram apresentaram distensão abdominal, fezes ressecadas e escassas e, nos bovinos que morreram, eram pastosas, escuras e fétidas; nesses havia também desidratação acentuada e palidez de mucosas. Três bovinos foram necropsiados e os achados patológicos eram constituídos principalmente por distensão acentuada do abomaso associada a grande quantidade de conteúdo alimentar ressecado coberto por coágulos de sangue. No abomaso havia úlceras, com perfuração da parede em um dos bovinos. A alimentação de bovinos de maior exigência nutricional com silagem de girassol de características indesejáveis como única fonte de volumoso foi o principal fator para a compactação de abomaso nos casos apresentados.


An outbreak of primary abomasal impaction associated with consumption of sunflower silage occurred in a dairy cattle herd from the state of Minas Gerais. Six of 21 dry cows in late pregnancy fed with sunflower silage died. Cattle that became ill presented abdominal distension and scant and dried feces. In the animals that died, severe dehydration, pale mucous membranes, dark, sticky and stinking feces were seen. Three cows were necropsied and the main pathological findings consisted of severe abomasal distension associated with a large quantity of dried alimentary content covered by bloody clots. Ulcers were found in abomasum, with perforation in one cow. Feeding cattle with high nutritional needs, with sunflower silage of undesirable characteristics as unique source of roughage was the main cause for the abomasal impaction.

ABSTRACT

La presencia de Organismos Asociados a Helicobacter (HLO), en el estomago de perros y gatos ha sido descrito previamente. El objetivo de este estudio fue evaluar la presencia de Organismos Asociados a Helicobacter, después de 21 días de tratamiento en perros asintomáticos. Siete perros fueron tratados durante 21 días con doxiciclina comercial en dosis 20mg/kg/día. Muestras de estomago fueron colectadas por gastroendoscopia. Secciones de tejido gástrico fueron procesadas, coloreadas con Hematoxilina y Eosina (H&E) y observadas en el microscopio óptico. Ninguno de los perros presento signos clínicos previos de enfermedad gastrointestinal. En el examen gastroendoscopico previo al tratamiento fue observada una mucosa gástrica normal en 1/7 perros, gastritis aguda superficial 3/7, gastritis crónica superficial 1/7, gastritis crónica atrófica 1/7 y gastritis erosiva ulcerosa 1/7. El estudio histopatológico revelo gastritis aguda superficial, erosión focal e hiperqueratosis con infiltración de linfocitos en la lamina propia. La presencia de bacterias tipo espiroquetas en el moco gástrico y en las glándulas fúndicas fue observada y asociada con lesiones gástricas. La evaluación gastroendoscopica después del tratamiento con doxiciclina revelo: 4/7 perros con mucosa gástrica normal, 2/7 con gastritis aguda superficial y 1/7 con gastritis crónica superficial. Los cortes histológicos de mucosa gástrica evidenciaron gastritis aguda superficial, erosión focal e hiperqueratosis focal infiltrado por linfocitos en la lámina propia. Ninguna muestra mostró bacterias tipo espiroquetas después del tratamiento con doxiciclina.Estos resultados nos permiten concluir que el tratamiento con doxiciclina es efectivo sobre la presencia de Organismos Asociados a Helicobacter en la mucosa gástrica de caninos


The presence of gastric Helicobacter-like organisms (HLO) in the stomach of dogs and cats has been known for many years, but the relationship between those organisms and gastric disease remains controversial. The objective of this study was to evaluate the presence of Helicobacter like organisms after twenty one days of treatment in asymptomatic dogs. Seven dogs were treated for 21 days with commercial doxycycline at a dose of 20mg/kg/day. Stomach samples were collected by gastroendoscopy from 7 dogs, before an after doxycycline treatment. Gastric tissue sections were prepared and stained with Hematoxilin & Eosin (H&E) for light microscopy. None of these dogs showed previous clinical signs of gastrointestinal disease. In the gastroendoscopy study after of doxycycline treatment we found a normal gastric mucosa in 1/7 dogs, acute superficial gastritis in 3/7, chronic superficial gastritis in 1/7, chronic atrophic gastritis 1/7 and chronic ulcer-erosive gastritis in 1/7. The histopathological study showed acute surface gastritis, focal erosion and hyperkeratosis with lymphocytes infiltration in the lamina propria. The presence of spirochetal shaped bacterias in the gastric mucus and fundus mucousglands were observed associated with gastric lesions. Gastroendoscopy after treatment with doxycycline reveled: 4/7 gastric mucosa normal, 2/7 superficial acute gastritis and 1/7 superficial chronic gastritis. Histopathology showed acute gastritis surface, erosion focal and hyperkeratosis focal infiltrated of lymphocytes in the lamina propria. None samples showed spiral shape bacterial after the treatment with doxyclyne. We conclude that doxycycline is effective for HLO on presence in gastric mucosa of dogs

ABSTRACT

A relação entre Helicobacter spp. e a presença de alterações histológicas na pars esophagea de suínos foi avaliada em 67 estômagos de animais em idade de abate. Para a identificação das helicobactérias, utilizou-se a técnica da PCR com primers específicos para o gênero Helicobacter. As alterações histológicas foram identificadas e classificadas como ulceração, erosão, degeneração epitelial, alongamento de papilas, hiperplasia, paraqueratose, intensidade do infiltrado inflamatório e aumento do número de folículos linfoides. As alterações mais frequentemente encontradas na pars esophagea foram a degeneração epitelial e o alongamento de papilas, observadas em 83,5 por cento (n=56) das amostras analisadas. Em 77,5 por cento (n=52) das amostras, observou-se paraqueratose e em 61,1 por cento (n=41) hiperplasia epitelial. Quarenta e sete (70,1 por cento) foram positivas na PCR para Helicobacter spp. Nessas amostras a erosão foi a lesão mais observada (40,2 por cento), seguida de ulceração da mucosa (11,9 por cento). Em 58,2 por cento das amostras positivas na PCR, não foram observadas ulcerações de mucosa. Observou-se associação significativa (P=0,003) entre a presença de Helicobacter spp. e a degeneração epitelial da pars esophagea de suínos em idade de abate.


The association between histological findings of gastric mucosa in pigs at slaughtering age and the presence of Helicobacter spp., identified by PCR, assay was investigated. Stomachs from 67 pigs were examined. Histological changes of pars esophagea were identified and classified as gastric ulcers, erosion, degeneration, distortion of papils, hyperplasia, paraqueratosis, and number of lymphoid follicles. Microscopic analysis revealed the most frequent alteration: 83.5 percent (n= 56) stomachs with epithelial degeneration and distortion of papils. Paraqueratosis of pars esophagea was observed in 77.5 percent (n=52) of the samples and epithelial hyperplasia in 61 percent (n=41). Forty-seven (70.1 percent) pigs were positive to Helycobacter spp. by PCR. Erosion of pars esophagea and ulceration were the most frequent findings in Helicobacter spp. PCR-positive pigs, occurring, respectively, in 40.2 percent and 11.9 percent. The frequency of animals without ulceration and Helicobacter spp. PCR-positive was 58.2 percent. It was observed a significant association (P=0.003) between Helicobacter spp. and epithelial degeneration of gastric mucosa in pigs at slaughtering age.

ABSTRACT

Recent studies have suggested that amoxycillin may possess gastroprotective effects in addition to its known antimicrobial properties. Therefore, the present study was undertaken to investigate the potential gastric protective effects of amoxycillin and to determine its possible mechanism[s] of action in rats. Ethanol-induced gastric mucosal lesions in rats were used as an animal model. Nonprotein sulphydryl levels were measured spectrophotometrically. The antioxidant effect of amoxycillin was studied by luminol-dependent chemiluminescence technique in-vitro. Amoxycillin produced marked protection against ethanol-induced gastric lesions. The protective effect of amoxycillin was lost by prior treatment with a dose of indomethacin that is known to inhibit prostaglandin biosynthesis without induction of gastric ulcers. Furthermore, the concentration of nonprotein sulphydryls decreased significantly in gastric mucosa after administration of ethanol. Treatment with amoxycillin prevented this depletion. Additionally, amoxycillin dose-dependently inhibited the phorbol myristate acetate stimulated luminol dependent chemiluminescence responses of isolated human polymorphonuclear leukocytes invitro. These data indicate that the gastric protection effects of amoxycillin against ethanol-induced lesions may include generation of mucosal.prostaglandins, prevention of nonprotein of sulphydryl depletion and antioxidant properties

ABSTRACT

During a period of ten year [1981 - 1990] the total of 14 cases of abomasal disorders in calves up to 6 months of age such as: left abomasal displacement [n= 2], abomasal tympany with right displacement [n= 3], abomasal torsion [approx 360°] [n= 1], abomasal impaction [n= 6] and incarcerated abomaso umbilicus [n= 2] were diagnosed clinically and treated surgically. In most cases, abdominal pain and distention, abdominal fluid and/or metallic sounds and suspended or altered defaecation were seen and the condition was confirmed throughout the exploratory laparotomy. Thirteen cases were cured successfully after surgical intervention but one case of abomasal tympany was died due to intestinal blockage. With respect to the infrequency of abomasal disorders in calves, they need to be recognized and treated promptly if a successful outcome is to be obtained

ABSTRACT

É relatado caso de intussuscepçäo gastroesofágica em cadela de 3 meses de idade, da raça Pastor Alemäo, afecçäo rara nesta espécie. O animal apresentou sintomas de regurgitaçäo e dispnéia acentuada, sendo o diagnóstico clínico confirmado por meio de exame radiográfico do tórax. Preconizou-se, após a reidrataçäo do cäo, o tratamento cirúrgico que constou de laparotomia, reduçäo do estômago à sua posiçäo anatômica e fundoplicatura gastroesofágica. No período pós-cirúrgico, notou-se melhora dos sintomas, porém no 7§ dia o animal veio a óbito, näo sendo possível determinar a causa. Tecem-se comentários sobre a provável etiologia do processo, a possibilidade de tratamento cirúrgico e a associaçäo de esofagopatias relacionadas à intussuscepçäo gastroesofágica
