Parâmetros ósseos de codornas de corte suplementadas com diferentes níveis de vitamina A, de 15 a 35 dias de idade / [Parameters of bone of meat-type quail supplemented with different levels of vitamin A from 15 to 35 days of age]

Avaliou-se o efeito da utilização de níveis crescentes de vitamina A sobre os parâmetros ósseos de codornas de corte de 15 a 35 dias de idade. Foram utilizadas 1520 codornas, não sexadas, com peso médio inicial de 85±4,25g, distribuídas em um delineamento inteiramente ao acaso, totalizando oito tratamentos com cinco repetições e 38 codornas por unidade experimental. Os tratamentos consistiram de oito níveis de suplementação de vitamina A (0; 4.500; 6.000; 7.500; 9.000; 10.500; 12.000 e 13.500UI/kg da dieta). O período experimental foi de 15 a 35 dias de idade. Os ossos analisados apresentaram uma redução linear para o índice de Seedor, resistência óssea e teor de cinzas do fêmur e da tíbia de acordo com os níveis de suplementação de vitamina A. A suplementação de vitamina A para codornas de corte de 15 a 35 dias de idade mostrou resultados negativos para a qualidade óssea, com a necessidade de mais estudos sobre seu antagonismo com a vitamina D.(AU)

This study evaluated the effect of using increasing levels of vitamin A on bone parameters in meat-type quails from 15 to 35 days old. A total of 1520 unsexed quail with an average initial weight of 85g distributed in a completely randomized design, totaling eight treatments with five replicates and 38 quails per experimental unit were used. The treatments consisted of eight vitamin supplementation levels A (0; 4,500; 6,000; 7,500; 9,000; 10,500; 12,000 and 13,500IU / kg diet). The experimental period was 15 to 35 days of age. The bones analyzed showed a linear reduction to the Seedor index, bone strength and ash content of the femur and tibia according to vitamin supplementation levels Vitamin A supplementation for cutting quails from 15 to 35 days of age showed negative results for bone quality, with the need for more studies on its antagonism to vitamin D.(AU)

Multidrug-resistant Escherichia coli isolated from a dog with a history of urolithiasis: case report / Escherichia coli multirresistente isolada de cão com histórico de urolitíase: relato de caso

Bacterial resistance is a reality in both human and veterinary health, it limits the therapeutic arsenal and raises the costs of the patient's treatment. A dog with signs of cystitis received treatment with 5mg/kg enrofloxacin at three consecutive times, with low effectiveness. The presence of urethral uroliths was identified and urohydropulsion was done. The animal presented a new obstruction, for which a cystotomy was performed, but continued with signs of infection. Uroculture and antimicrobial susceptibility test were then performed. Escherichia coli was identified, which was resistant to 13 antibiotics, being sensitive only to piperacillin-tazobactam and amikacin. In the screening test for ß-lactamase, the production of ESßL was detected. The qPCR indicated the presence of the bla CTXm, bla DHA, bla OXA, bla IMP, bla TEM, bla GIM, bla SIM, bla SPM and bla SME genes, which may lead to a phenotypic resistance profile for ampicillin, amoxicillin-clavulanate, aztreonam, cefepime cefoxitin, cefuroxime, ceftazidime, ceftriaxone, imipenem, and piperacillin-tazobactam. This case reaffirms the value that laboratory analysis adds to the diagnosis and treatment of cystitis and urolithiasis, which can define the direction of evolution of the prognosis and the speed at which the patient's health will be restored.(AU)

A resistência bacteriana aos antibióticos é uma realidade, tanto na saúde humana quanto veterinária, limita o arsenal terapêutico e eleva os custos relacionados ao tratamento do paciente. Um cão, com sinais de cistite, recebeu tratamento com enrofloxacina, na dose de 5mg/kg, em três momentos seguidos, com baixa efetividade. Identificou-se presença de urólitos uretrais e foi feita uro-hidropropulsão. O animal apresentou nova obstrução, para a qual foi realizada uma cistotomia, mas continuou com sinais de infecção. Realizou-se, então, urocultura e teste de antibiograma. Foi identificada Escherichia coli, que se mostrou resistente a 13 antibióticos, sendo sensível somente à piperacilina-tazobactam e amicacina. No teste de triagem para ß-lactamase, detectou-se a produção de ESßL. A qPCR indicou presença dos genes blaCTXm, blaDHA, blaOXA, blaIMP, blaTEM, blaGIM, blaSIM, blaSPM e blaSME, que podem conduzir um perfil fenotípico de resistência para ampicilina, amoxicilina-ácido clavulânico, aztreonam, cefepima, cefoxitina, cefuroxima, ceftazidima, ceftriaxona, imipenem, piperacilina-tazobactam. Este caso reafirma o valor que a análise laboratorial agrega ao diagnóstico e tratamento da cistite e da urolitíase, podendo definir o sentido de evolução do prognóstico e a velocidade em que a saúde do paciente será restabelecia.(AU)

Ecologia da comunidade de helmintos gastrointestinais de tartarugas-verdes ( Chelonia mydas ) recolhidas no litoral do Espírito Santo / Community ecology of gastrointestinal helminths from green turtles (Chelonia mydas) collected in the coast of Espírito Santo

A tartaruga-verde, Chelonia mydas, apresenta distribuição cosmopolita. No Brasil, ocorre na costa, porém desova em ilhas oceânicas. A helmintofauna de tartarugas-verdes é diversificada, podendo-se dizer que tem a maior diversidade comparada com outras espécies de tartarugas. Objetivou-se avaliar aspectos ecológicos da comunidade de helmintos gastrointestinais e relacionar com a condição corporal de tartarugas-verdes recolhidas no litoral do Espírito Santo. Foram utilizados 36 exemplares juvenis da espécie C. mydas. O trato gastrointestinal foi separado e dividido em porções: esôfago/estômago, intestino delgado e intestino grosso. Cada porção foi inspecionada à procura de parasitos, e os exemplares encontrados foram separados para posterior identificação. Das 36 tartarugas avaliadas, 34 estavam parasitadas por helmintos (94,44%), com um total de 10.734 helmintos. Foram encontradas 18 espécies de trematodas pertencentes a quatro famílias. A riqueza de espécies encontrada foi de 4,29±2,19 (1-10) e a intensidade média de infecção foi de 315,64±281,83 (2-994) helmintos. Os parasitos mais prevalentes foram Cricocephalus albus, Metacetabulum invaginatum e Neoctangium travassosi, ambos com 61,11% (22/36), Pronocephalus obliquus com 33,33% (12/36), e Glyphicephalus lobatus com 30,55% (11/36). O helminto mais abundante foi M. invaginatum com 70,63 helmintos/animal, seguido de C. albus com 58,77 helmintos/animal e N. travassosi com 41,75 helmintos/animal.(AU)

The green turtle, Chelonia mydas has worldwide distribution. In Brazil, it is found on the coast, but spawning occurs on oceanic islands. The helminth fauna of green turtles is diverse and has the greatest diversity when compared with other species of turtles. This study aims to evaluate ecological aspects of gastrointestinal helminth community and connect to the body condition of green turtles collected on the coast of Espírito Santo. A total of 36 juvenile specimens of the species C. mydas were used. The gastrointestinal tract was removed and divided into portions: esophagus/stomach, small intestine and large intestine. Each portion was inspected looking for parasites and the specimens found were separated for later identification. Of the 36 turtles evaluated, 34 were parasitized by helminths (94.44%), with a total of 10,734 helminths. Results include findings of 18 species of trematodes belonging to four families. The species richness was 4,29 ± 2,19 (1-10) and the mean intensity of infection was 315,64 ± 281,83 (2-994) helminths. The prevalent parasites were Cricocephalus albus, Metacetabulum invaginatum and Neoctangium travassosi, both with 61,11% (22/36), Pronocephalus obliquus with 33,33% (12/36), and Glyphicephalus lobatus with 30,55% (11/36). The abundant helminth was Metacetabulum invaginatum with helminths 70,63/animal, followed by C. albus with helminths 58,77/animal and N. travassosi with helminths 41,75/animal.(AU)

Aspectos clínicos, cirúrgicos, histológicos e pós-operatórios de oito cadelas com leiomioma vaginal / Clinical, surgical, histological and postoperative aspects in the case of eight bitches with vaginal leiomyoma

O presente trabalho reporta as características clínicas e cirúrgicas de oito casos de cadelas portadoras de leiomioma vaginal, com histórico de aumento de volume na região perineal, aparecimento de massa pela vulva, disquezia, tenesmo e disúria. As pacientes foram submetidas à cirurgia de episiotomia para ressecção da massa neoplásica, e em quatro casos foi necessária a ovariossalpingo-histerectomia. Porém, uma delas apresentou recidiva, e, no segundo procedimento cirúrgico de exérese de neoformação, o histopatológico diagnosticou leiomiossarcoma. A paciente ainda apresentou mais duas recidivas, até o proprietário optar pela eutanásia. Decorridos quatro meses, as sete cadelas diagnosticadas com leiomioma não apresentaram recidiva, e os proprietários relataram ausência de sinais relacionados com a doença descrita. Conclui-se que a episiotomia para ressecção da massa vaginal e a ovariossalpingo-histerectomia nas cadelas inteiras nos casos de tumores vaginais benignos são tratamentos satisfatórios, com bom prognóstico, ao contrário do leiomiossarcoma.

This study reports the clinical and surgical procedures of eight cases of bitches with vaginal leiomyoma. All animals presented increased volume in the perineal region, and exteriorization of the vulva, dyschezia, tenesmus and dysuria. The patients underwent episiotomy surgery for resection of the neoplastic mass, and ovariosalpingohisterectomy in four cases. However, one had recurrence on the second surgical procedure for removal of neoformation, histopathological diagnosed leiomyosarcoma, the patient also had two more relapses, until the owner chose euthanasia. After four months, the seven dogs diagnosed with leiomyoma showed no recurrence and the owners reported no signs of the disease described. We concluded that episiotomy for vaginal mass resection combined with ovariohysterectomy in cases of benign vaginal tumors have shown satisfactory treatment with good prognostic.

Distribution and factors associated with Fasciola hepatica infection in cattle in the south of Espírito Santo State, Brazil

Fasciolosis is a disease that affects the liver parenchyma and bile ducts of numerous animals, including humans, which causes economic losses and threatens public health. The present work aimed at reporting the distribution and factors connected with Fasciola hepatica infection in cattle in ten municipalities in southern Espírito Santo, Brazil, between 2008 and 2009. During this period, 50 rural properties in ten cities were analyzed and fecal samples from 10 percent of the cattle on each farm were collected. Of the 717 samples analyzed, 154 (21.33 percent) presented Fasciola hepatica eggs. As for the 50 rural properties studied, 32 (64 percent) had animals positive for fasciolosis. Throughout the evaluation, it was observed that 42 (84 percent) rural properties had flooded areas, 33 (66 percent) were located at altitudes less than 226 meters, in 36 (72 percent) mollusks were found, 47 (94 percent) had other definitive hosts (horses, sheep, goats) and 25 (50 percent) had previous cases of bovine fasciolosis. The present results showed a high rate of bovine fasciolosis in the analyzed region whereas infected animals are present in all the municipalities. Based on statistical analysis, it was concluded that there was an association between the presence of flooded areas and other definitive hosts in rural properties where bovine fasciolosis was detected.

Níveis séricos da gama-glutamiltransferase em cães com e sem infecção natural por Leishmania (Leishmania) chagasi / Serum levels of gamma-glutamyl transferase in dogs naturally infected or not by Leishmania (Leishmania) Chagasi

The serum levels of Gamma-GT in dogs naturally infected by Leishmania (Leishmania) chagasi were evaluated. Two groups of animals were used: the first with 41 naturally infect dogs and the second with 14 uninfect animals. The results showed 17.1% (7/41) dogs presented high levels of gamma-GT, but no difference between groups was observed. So, the serum level of gamma-GT is not a tool for diagnosis of visceral leishmaniasis in dogs.

Seasonal abundance of equine strongyles (Nematoda: Strongylidae) in the State of Rio de Janeiro, Brazil

Estudou-se a ocorrência sazonal de formas larvares e adultas de estrongilídeos nas mucosas do estômago, intestino delgado, ceco, colon ventral, colon dorsal e reto de 30 eqüídeos no Estado do Rio de Janeiro. Os grandes estrongilídeos foram encontrados em todas as mucosas e duas alíquotas de 5% do conteúdo foram retiradas para a procura de pequenos estrongilídeos. Artéria mesentérica, fígado, pâncreas e peritônio foram também examinados para larvas de estrongilídeos. As mucosas foram examinadas pela técnica de transiluminação. Larvas de Strongylus equinus (P<0,10) e adultos de Strongylus vulgaris (P<0,05) foram mais abundantes na estação seca. Larvas escistadas de ciatostomíneos o foram na estação chuvosa (P<0,02).

Advertisement call of Hyla jimi and Hyla elianeae (Anura, Hylidae) in the Botucatu Region, São Paulo, Brazil

Neste trabalho apresenta-se a descrição do canto de anúncio de H. jimi, para a localidade tipo, e de H. elianeae, ainda desconhecida da literatura. As atividades de campo foram desenvolvidas de agosto de 1997 a junho de 1999. As gravações foram efetuadas em ambientes de área aberta na região de Botucatu, Estado de São Paulo. Foram registradas vocalizações de 100 exemplares, 49 de H. jimi e 51 de H. elianeae; foram analisadas nove características do canto de anúncio. O canto de anúncio de ambas as espécies consiste em uma série consecutiva de notas simples com taxa de repetição relativamente rápida. Machos de H. jimi e H. elianeae apresentaram dois padrões de emissão de notas. Um emitido por indivíduos iniciando a atividade de vocalização ou isolado do agregado e outro emitido por machos em atividade de coro, interagindo com machos vizinhos. Foram verificadas diferenças significativas na estrutura temporal nos dois padrões de vocalizações.

Advertisement call of Hyla jimi and Hyla elianeae (Anura, Hylidae) in the Botucatu Region, São Paulo, Brazil

In this work we present a description of the advertisement call of H. jimi, the locality type, and of H. elianeae, until now unknown in the literature. Field activities were carried out from August 1997 through June 1999; recordings were made in two open-area environments in the Botucatu region, São Paulo State. Vocalizations of 100 individuals (49 H. jimi and 51 H. elianeae) were recorded; nine characteristics of the advertisement call were examined. The advertisement calls of both species consist of consecutive series of simple notes with relatively fast repetition rates. Males of H. jimi and H. elianeae presented two patterns of note emission: one emitted by individuals beginning vocalization activity or isolated from the aggregate, and another emitted by males in chorus activity interacting with closely neighboring males. A significant difference was verified in the temporal structure of the two vocalization patterns.

Bioacoustic analysis of advertisement call in Hyla nana and Hyla sanborni (Anura, Hylidae) in Botucatu, São Paulo, Brazil

Vocal communication traits of Hyla nana and Hyla sanborni, of the nana species group, were studied from August 1997 until June 1999 in two large permanent ponds located in an open field in Botucatu, São Paulo State. One hundred thirty-one individuals, 71 of H. nana and 58 of H. sanborni, were recorded in the beginning of their vocalization activity and during chorus vocalization. The rhythms of sound emission on the two occasions were different. An advertisement call consists in a consecutive series of simple notes in rapid succession. Both species have two types of notes in their advertisement calls, here named types A and B. Type A notes are introductory and have a longer and higher pulse number and are emitted more frequently in the beginning of vocalization activity. Introductory notes are the first to be emitted in chorus activity. Type B notes are secondary, of shorter duration and lower pulse number, and are emitted during chorus vocalization. The notes of both types differ significantly in their temporal structure. Both species present acoustic segregation in both spectral and temporal structure.

Oviposition and predation by Speciomerus revoili (Coleoptera, Bruchidae) on seeds of Acrocomia aculeata (Arecaceae) in Brasília, DF, Brazil

Oviposition and predation levels by Speciomerus revoili bruchid beetles were quantified on fruits and seeds of the macaúba palm, Acrocomia aculeata, collected from below mother-trees within the Sarah Kubitschek Park of Brasília, DF, Brazil. A maximum of 12 eggs per fruit were found, with high variations observed between samples. No clear pattern was found for the distribution of the number of eggs per fruit, perhaps due to the artificial conditions of the study area, the absence of dispersers and/or the plasticity in the oviposition behavior of the insect. The number of eggs per fruit was not related to fruit size, but was associated with their availability under the tree-mother. This suggests that the density of eggs per fruit is a balance between the availability of this resource and the number of females in the beetle population. The observed mortality rate, from the egg phase to the final larval stages, was over 75 percent. About 40 percent of the seeds of Acrocomia aculeata were predated by Speciomerus revoili

A oviposição e os níveis de predação de Speciomerus revoili foram quantificados em frutos e sementes da palmeira Acrocomia aculeata, coletados sob a árvore-mãe, no Parque Sarah Kubitschek, em Brasília, DF. Foi encontrado um máximo de 12 ovos por fruto, com grandes variações entre as amostras. Não foi encontrado um padrão muito claro na distribuição de ovos por fruto, talvez devido às condições artificiais da área de estudo, à ausência de dispersores e a uma plasticidade no comportamento de oviposição do inseto. O número de ovos por fruto não foi relacionado ao tamanho do fruto, mas à sua disponibilidade sob a árvore-mãe. Sugere-se que a densidade de ovos por fruto seja um ajuste entre a disponibilidade deste recurso e a quantidade de fêmeas na população do besouro. A taxa de mortalidade observada da fase de ovo até as larvas dos últimos estádios ficou acima de 75%. Cerca de 40% das sementes de Acrocomia aculeata foram predadas por Speciomerus revoili.

Atresia de esófago. Análisis de 89 pacientes / Esophageal atresia. Analysis of 89 patients

En el período comprendido entre Enero de 1991 y Junio de 1996, 89 pacientes con Atresia de esófago (AE) fueron tratados en el Servicio de Cirugía Pediátrica del Hospital Infantil Pequeño Príncipe. Trece pacientes (14,6 por ciento) tenían atresia sin fístula traqueal (tipo I) y 76 pacientes (85,4 por ciento) atresia con fístula traqueoesofágica distal (tipo III). El peso promedio preoperatorio fue de 2.440g (950g a 3.850g) y hubo prevalencia del sexo masculino en la relación de 1,85:1. Las malformaciones asociadas fueron encontradas en 36 pacientes (39,7 por ciento) siendo: cardiovasculares en 11, renales en 4, gastrointestinales en 3 y múltiples en 18 pacientes. Se realizó la anastomosis esofágica término-terminal en 67 pacientes, gastrotomía y cierre de la fístula traqueoesofágica en 6, esofagostomía asociada a gastrotomía en 10, gastrotomía y posterior esofagostomía en 5 y sólo gastrotomía en uno. Cuatro pacientes requirieron reemplazo esofágico tardío de AE tipo I. Las complicaciones postoperatorias de la anastomosis término-terminal fueron: fístula esófago-mediastinal en 3 pacientes, dehiscencia total en 5, estenosis en 18 y recurreccia de la fístula traqueoesofágica en dos. El reflujo gastroesofágico fué encontrado en 15 pacientes. La sobrevida global fué de 60 pacientes (67,4 por ciento)

Hematological changes induced by Bothrops jararaca venom in dogs

The mechanism of consumption coagulopathy observed in cases of human envenomation by Bothrops jararaca is well established. However, this mechanism may vary according to the animal species studied. In order to study both the clinical and laboratory aspcts of bothropic envenomation in dogs, a sublethal defibrinating dose of venom (100 µg/kg) was given intravenously. A coagulopathy similar to that observed in humans - including fibronogen depletion, consumption of factors II, X, V and antithrombin III, and moderate thrombocytopenia -was observed. The presence of circulatin activated platelets was also noted. Neutrophilic leukocytosis, lymphopenia, and monocytosis occurred at different times. Erythrocytic values remained normal in dogs treated with B. jararaca venom compared with those treated with saline alone. The erythrocyte sedimentation rate fell rapidly after venom administration and this fall was correlated logarithmically with fibrinogen concentration. Since the effect of envenomation in dogs is similar to that in humans, it was concluded that the dog can be used as a good animal model for studying human venom-induced coagulopathy
