Radiographic pelvimetry in the Tamandua tetradactyla / Pelvimetria radiográfica em Tamandua tetradactyla

The pelvis, formed by the ilium, ischium and pubis, forms the coxal, which is the largest of the flat bones of the skeleton, with an important role in the physiology of birth. Vastly studied in domestic animals, there is still much to be investigated regarding the anatomical classification in wild animals, mainly aiming to improve the understanding of the reproductive management of the species. Tamandua tetradactyla is one of these species in which morphological studies are still scarce, especially when it comes to reproductive aspects. In this context, we carried out the pelvimetry of T. tetradactyla using radiographic images to anatomically and obstetrically classify the pelvis of this species, classifying it as dolicopelvic, with evidence of homoscedasticity of the samples. Verification of the existence of a relationship between the variables studied by the statistical method of Pearson coefficients showed positive correlations of high intensity for the diameters studied (P < 0.01). Thus, we believed that our findings may support future reproductive studies in this species.

A pelve, constituída pelo ílio, ísquio e púbis, forma o coxal, sendo este o maior dos ossos planos constituintes do esqueleto, com importante papel na fisiologia do parto. Vastamente estudada em animais domésticos, ainda existe muito à se investigar quanto a classificação anatômica nos animais selvagens, visando principalmente melhorar a compreensão do manejo reprodutivo das espécies. Tamandua tetradactyla é uma dessas espécies em que estudos morfológicos ainda são escassos, principalmente quando se trata de aspectos reprodutivos. Neste contexto realizamos a pelvimetria do T. tetradactyla por meio de imagens radiográficas para classificar anato-obstetricamente a pelve desta espécie classificando-a como dolicopélvica, sendo evidenciada homoscedasticidade das amostras. A verificação da existência de relação entre as variáveis estudadas pelo método estatístico dos coeficientes de Pearson mostrou correlação positivas de alta intensidade para os diâmetros estudados (P< 0,01). Assim, acreditamos que nossos achados poderão subsidiar futuros estudos reprodutivos nesta espécie.

The vertebral column of Chaetophractus villosus (Desmarest, 1804) (Chlamyphoridae, Cingulata, Xenarthra): anatomy and Thoracolumbar variation. Spinal cord relation

Mammals of the Xenarthra clade show a large number of unusual characters in the skeleton, mainly in the vertebral column. In spite of the importance of the knowledge on the axial skeleton in this group, there are no detailed studies on the morphology of the entire vertebral column. Here we performed a comprehensive study of the vertebral column of Chaetophractus villosus (Desmarest, 1804), a representative of Chlamyphoridae, in order to provide a more reliable comparative framework among armadillos. Morphological description was based on 44 adult postcranial axial skeletons. As a complement to the morphological descriptions of the skeleton we studied the paths followed by blood vessels and nerves in close relationship to the axial skeleton (using 13 fresh adult specimens, six females and seven males, part of the doctoral Thesis of one of the authors). Intraspecific variability in the thoracolumbar number in C. villosus was also evaluated. We identified certain variability in the position of the first vertebral pair that bears a xenarthral facet, ranging from T4-T5 to T6-T7, being T5-T6 and T6-T7 the most frequent positions. The second pair of xenarthrales is set near the thoracolumbar limit, and ranges between T9-T10 and T11-L1 (T10-T11 in most specimens). The variability in the total number of thoracolumbars in C. villosus falls within the range of most mammals and sets controversy about an important morphological feature that groups extant Xenarthra and Afrotheria into the southern placentals (Atlantogenata). In this regard, a more comprehensive study of this character is necessary to elucidate the patterns of distribution of this trait among xenarthrans.(AU)

Pelvic limb amputation in a giant anteater (Myrmecophaga tridactyla) traumatized by an agricultural harvester

Background: The giant anteater (Myrmecophaga tridactyla) returned to the category of vulnerable by the 2014 IUCN /SSC, due to the population reduction, less than 30%. The main reasons are: environmental degradation and fragmentation,being run over, burning, attacks by hunting dogs, illegal trade and diseases. It is very common to find these fractured patientsand the treatment is mostly surgical. Amputation is indicated when there are extensive lacerations and when reconstructivesurgery is not possible. The objective is to report a viable treatment option in fractured wild patients, contributing to thepreservation of the species.Case: It was received at the Veterinary Hospital Dr. Halim Atique - UNIRP an young female giant anteater (M. tridactyla)weighing 5.75 kg, brought by the Environmental Forestry Police of the municipality of São José do Rio Preto - SP, foundin the region of Olímpia at a gas station.

Displasia renal em filhote de tamanduá bandeira (Myrmecophaga trydactila) de vida livre - aspectos ultrassonográficos e tomográficos / Renal dysplasia in a free-living giant anteater cub (Myrmecophaga tridactyla) - ultrasonographic and tomographic aspects

Background: Renal dysplasia is a congenital disorder that occurs during differentiation of the renal parenchyma or as aconsequence of a functional and/or structural obstruction of the lower urinary tract. In wild animals, this pathology has beenreported in cynomolgus monkeys (Macaca fascicularis), golden hamsters (Mesocricetus auratus) and African elephants(Loxodanta africana). However, there are no reports of the disease in the giant anteater (Myrmecophaga tridactyla). Thus,this paper describes a case of renal dysplasia in a free-living giant anteater cub, which was sent to the wild animal clinicof the Federal University of Mato Grosso (UFMT) in Cuiabá, MT, Brazil.Case: The rescued animal had a good body condition score and clinical parameters within the normal range for the species.After a routine clinical evaluation, the anteater cub was subjected to radiography and ultrasound tests. Blood tests, serumtests for hepatic and renal profiles, urinalysis, urinary protein creatinine ratio, and chest X-rays did not reveal significantchanges. However, the abdominal ultrasound examination revealed a volumetric loss of about 1.17 cm in length in theleft kidney, and a renal length to aortic artery diameter ratio of approximately 2.8. This kidney showed irregular contours,loss of corticomedullary demarcation, with preserved echogenicity and cortical echotexture. The right kidney showedthe standard size of the species, with a length of approximately 3.08 cm. In view of the suspicion of renal dysplasia, acontrast-enhanced CT scan was performed in order to assess the dynamics of uptake and excretion of the contrast mediumin the affected kidney and in the ipsilateral collecting system. An examination of the tomographic images indicated thatthe volume of the left kidney was reduced, isodense in relation to the right kidney, with discrete and homogeneous uptakein all phases after administration of the contrast medium, no occurrence of nephrogram...

Anatomia macroscópica interna e avaliação elétrica do coração de Bradypus variegatus / Internal macroscopic anatomy and electrical evaluation of the Bradypus variegatus heart

The Bradypus variegatus species presents peculiar anatomophysiological properties and many aspects of its organic systems still need to be clarified, especially regarding the cardiovascular system, given its participation in vital activities. Disorderly anthropic action has had drastic consequences in sloth populations and the need to treat sick and injured animals is increasingly common. To this end, the importance of knowing its characteristics is emphasized. Therefore, this study proposed to describe the internal macroscopic structures of the sloth's heart, as well as to measure the ventricular walls and indicate the electrical activity of the organ. For the dissections, 15 Bradypus variegatus cadavers were used (1 young female, 9 adults females and 5 adult males) belonging to the Área de Anatomia of the Departamento de Morfologia e Fisiologia Animal (DMFA), Universidade Federal Rural de Pernambuco (UFRPE), Recide, PE, Brazil. After they were fixed and preserved, the specimens received a midsagittal incision in the chest, followed by soft tissue folding and removal of ribs to access the heart. The organ was derived from the cavity and sectioned sagittal medially to identify its internal anatomy. Ventricular walls and interventricular septum were measured with a steel caliper (150 mm / 0.02 mm). An electrocardiogram was performed to determine the electrical profile on 5 healthy B. variegatus sloths, living under semi-livestock conditions at the Recife Zoo, PE, Brazil. The electrodes were taken from the regions, scapular and glutes of the animals that were called hugging a keeper during the procedure, carried out in the Zoo itself, using a portable device. Based on the data obtained, sloths have cardiac chambers separated by septa, however between atria and ventricles, in both antimeres, there are atrioventricular ostia, where valves are found, consisting of 3 valves on the right and 2 on the left. The atria are practically smooth inside and have their cavity enlarged by the atria, the right being larger than the left, these having a greater amount of pectineal muscles in relation to the atria. The ventricles have trabeculae and papillary muscles, 3 on the right and 2 on the left. These muscles hold the tendinous chords that connect the valves. The existence of trabeculae marginal septum was not evidenced. The thickness of the wall of the left ventricle, as well as that of the interventricular septum, proved to be greater than the thickness of the wall of the right ventricle, regardless of the age or sex of the animals. Based on the electrocardiographic recordings, the sloths presented sinus rhythm, with a heart rate between 67 and 100 bpm. The electrical axis ranged from -60º to -90º. The P wave is smoother than the QRS complex. While the S-T segment was classified as isoelectric. The T wave was shown to be + and predominantly > or = at 25% of the S wave, which characterized an rS type QRS deflection in both females and males. The general characteristics of the cardiac chambers in sloths are similar to those observe in other domestic and wild mammals. However, the presence of pectineal muscles associated with the atria and auricles differs from that observed in mammals such as the paca and raccoon and in birds such as the ostrich, which have trabecular structures in these cavities. The number of valves in sloths is equal to the anteater. However, it has a marginal trabeculae septum, not seen in Bradypus variegatus. According to the electrocardiographic findings, the rhythm was sinus, but much lower than that observed in the capuchin monkey, which also maintains arboreal habits.(AU)

Anatomical aspects of the forearm muscles of Myrmecophaga tridactyla / Aspectos anatômicos dos músculos do antebraço de Myrmecophaga tridactyla

The giant anteater is one of the species classified as vulnerable to extinction. Burning and being run over are among important causes in the decrease of individuals of this species and a better knowledge of the anatomy of these animals can contribute to the treatment of injured animals and their restoration to the environment. Thus, the objective of this work was to describe aspects of the anatomy of the muscles of the forearm of M. tridactyla. For this purpose, six adult specimens were used, three females and three males. The corpses were fixed with a 10% formaldehyde solution and preserved in vats containing the same solution. The thoracic limbs were dissected by routine dissection techniques. The forearm muscles of M. tridactyla were: brachioradialis; radial carpal extensor; common finger extensor; lateral finger extensor, ulnar carpal extensor; finger extensor I and II; long abductor of finger I; supinator, radial carpal flexor; ulnar flexor of the carpus, superficial flexor of the fingers, deep flexor of the fingers, pronator teres and square pronator, which were innervated by the radial, ulnar and median nerves. These muscles give a large volume to the forearm, are robust and have highly developed tendons, especially those involved with the flexion of the carpus, digits and elbow, actions that are fundamental to your defense habits and search for food.(AU)

O tamanduá-bandeira é uma das espécies classificadas em condição vulnerável à extinção. Queimadas e atropela-mentos estão entre causas importantes na diminuição de indivíduos desta espécie e um melhor conhecimento da anatomia des-tes animais pode contribuir para o tratamento de animais feridos e seu reestabelecimento ao meio ambiente. Assim, oobjetivo deste estudo foi descrever os aspectos da anatomia do antebraço do M. tridactyla. Para tanto, foram utilizados seis exemplares adultos, sendo três fêmeas e três machos. Os cadáveres foram fixados com solução aquosa de aldeído fórmico 10% e preser-vados em cubas contendo a mesma solução. Os membros torácicos foram dissecados pelas técnicas rotineiras de dissecação para evidenciação dos músculos, vasos e nervos da região. Os músculos do antebraço do M. tridactyla foram: braquiorradial; extensor radial do carpo; extensor comum dos dedos; extensor lateral dos dedos, extensor ulnar do carpo; extensor dos dedos I e II; abdutor longo do dedo I; supinador, flexor radial do carpo; flexor ulnar do carpo, flexor superficial dos dedos, flexor profundo dos dedos, pronador redondo e pronador quadrado. Estes músculos foram inervados pelos nervos ulnar e mediano. Juntos estes músculos conferem um grande volume ao antebraço, e suas características apontam para uma poderosa capaci-dade de exercer a flexão do carpo e dos dígitos, e ainda contribuir com os músculos do braço para a flexão do cotovelo, ações estas fundamentais aos seus hábitos de defesa e busca por alimento.(AU)

First records of Brazilian three-banded armadillo (Tolypeutes tricinctus,Mammalia, Cingulata, Chlamyphoridae) predation by jaguar (Panthera onca,Mammalia, Carnivora, Felidae)

The jaguar Panthera onca and the Brazilian three-banded armadillo Tolypeutes tricinctus are two threatened mammals that coexist in the Caatinga dry forests and the Cerrado savannas of Brazil. Yet, to the best of our knowledge, interactions between these species have not been reported in the literature. Here, we present the first records of P. onca predation on T. tricinctus from two different areas in the Caatinga in northeastern Brazil. We showed that P. onca can pierce the hard carapace of T. tricinctus, which may be possible due to its distinctly strong bite and associated predation behavior. We argue that P. oncamay be the most adapted non-human predator to feed on T. tricinctus, and that the smaller body sizes of P. onca individuals in the Caatinga may increase their likelihood to feed on smaller prey, including T. tricinctus. Thus, the originality of our records is probably more related to insufficient research in the areas where these species coexist than to the rarity of this interaction.(AU)

Osteossíntese femoral associada ao biovidro 60S em tamanduá-bandeira: relato de caso / Femoral osteosynthesis associated with 60s bioglass in tamanduá bandeira: case report

Atropelamentos de animais silvestres são frequentes e muitas vezes causam fraturas ósseas que, se não tratadas adequadamente, levam à morte do animal por complicações ou por inabilidade de sobrevivência no seu habitat natural. O objetivo do presente trabalho foi relatar o uso de placa associada ao pino intramedular e ao biovidro 60S (BV60S) para o tratamento de fratura de fêmur em tamanduá-bandeira. O animal foi resgatado pela polícia ambiental com suspeita de atropelamento. Foi sedado para avaliação clínica e radiográfica, que revelou fratura em fêmur direito. Utilizou-se dexmedetomidina como medicação pré-anestésica, midazolam e cetamina para indução, e isoflurano para manutenção. Também foi realizado bloqueio peridural com bupivacaína e morfina. A osteossíntese foi feita com placa bloqueada 2,7 e pino intramedular 2,5. Colocaram-se 4g de BV60S no foco de fratura para favorecer a osteogênese. O paciente teve recuperação funcional imediata do membro acometido. A reparação óssea ocorreu por segunda intenção, observando-se ossificação completa do calo com consolidação clínica, aos 30 dias, e remodelação quase completa, aos 180 dias. Conclui-se que o uso de placa e pino associado ao BV60S é eficiente no tratamento de fratura de fêmur em tamanduá, permitindo a rápida recuperação e a reintrodução do animal na natureza.(AU)

Roadblocks of wild animals are frequent and often cause bone fractures that if not properly treated lead to the death of the animal due to complications or inability to survive in its natural habitat. The objective of the present study was to report the use of plate rod and bioglass 60S (BG60S) for the treatment of femoral fracture in anteater. The animal was rescued by environmental police on suspicion of being hit. It was sedated for clinical and radiographic evaluation, which revealed a fracture in the right femur. Dexmedetomidine was used as preanesthetic medication, midazolam and ketamine for induction, and isoflurane for maintenance. Epidural blockade with bupivacaine and morphine was also performed. Osteosynthesis was done with a locking plate 2.7 and 2.5 intramedullary pin. 4G of BG60S was placed in the focus of fracture to favor osteogenesis. The patient had immediate functional recovery of the affected limb. The bone repair occurred by second intention, with complete ossification of the callus with clinical consolidation at 30 days, and near complete remodeling at 180 days. It is concluded that the use of plate rod to the BG60S is efficient in the treatment of femur fracture in anteater, allowing the rapid recovery and reintroduction of the animal in the wild.(AU)

Morphological features of the acupuncture points of bladder meridian in the giant anteater (Myrmecophaga tridactyla)

Background: The acupuncture points are considered a point in the skin of sensitivity to stimulation. The acupuncture meridians represent the communication between acupuncture points and internal organs. The giant anteater (Mirmecophaga tridactyla) is routinely attended in veterinary centers, and is pivotal to know its morphology and therapies such as acupuncture that, probably, can be used in medical practice. Thus, the aim of this study was to evaluate the morphological substrate in regions that correspond to the transposition of acupuncture points of the Bladder Meridian using radiography, ultrasonography, electrical impedance and histology in the giant anteater. Materials, Methods & Results: Seven giant anteaters (six males and one female) were used. The animals were from the Center of Medicine and Research in Wild Animals (CEMPAS), School of Veterinary Medicine and Animal Science, UNESP, Botucatu, São Paulo. The acupoints of Bladder Meridian evaluated were Bladder 11 (B-11), Bladder 18 (B-18), Bladder 23 (B-23), Bladder 25 (B-25), and Bladder 28 (B-28). The locations of the acupoints were transposed based on the location of these acupuncture points in dogs. Four animals were live and were used for radiographic, ultrasonographic, and electrical impedance analysis. Three animals were died and the fragments of this acupoints were destined to histological routine with hematoxylin and eosin (HE) and Masson’s Trichrome stains. The giant anteaters studied had fifteen thoracic vertebrae, three lumbar vertebrae, and five sacral vertebrae fused in a single bone. The acupuncture points were characterized by presence of abundant connective tissue at the superficial and intermuscular level, muscular fascia, and many neurovascular bundles in the dermal layer. These bundles consisted of nerves...

No exame ultrassonográfico, foi possível localizar, identificar, avaliar e mensurar os ovários e as estruturas uterinas, o colo do útero, o corpo do útero, o lúmen, o miométrio e o endométrio, fato nunca relatado na literatura para essa espécie. Esses dados podem ser utilizados como referência para avaliação clínica do trato reprodutivo de fêmeas de Myrmecophaga tridactyla considerada espécie vulnerável, para o diagnóstico de patologias reprodutivas, aplicação de biotecnologias ou avaliação do ciclo estral.(AU)

Blood transfusion in a young Myrmecophaga tridactyla (Pilosa, Myrmecophagidae): case report / Transfusão sanguínea emMyrmecophaga tridactylafilhote (Pilosa, Myrmecophagidae): relato de caso

The present study aims to report a transfusion therapy in a juvenile Myrmecophaga tridactyla. The patient had a chronic nonregenerative anemia associated with underdevelopment. This therapy was considered after a severe worsening of the clinical condition and laboratorial tests, in which severe anemia was confirmed, with no signs of recovery. The blood used was donated by a clinically healthy adult male of the same species, raised in captivity. The procedure was performed according to medical practice for small animals, since veterinary medicine reports described for xenarthrans are scarce. The result was satisfactory, with absence of late transfusion reactions and an improvement of the patient's overall condition, which demonstrates the possibility of using blood transfusion in anteaters as a therapeutic option.

O presente trabalho tem como objetivo relatar a realização de terapia transfusional em um exemplar filhote de Myrmecophaga tridactyla. O paciente apresentava um quadro crônico de anemia arregenerativa associada a um subdesenvolvimento. A terapia foi definida após piora severa do quadro clínico e dos exames laboratoriais, nos quais observou-se anemia severa, sem sinal de regeneração. O sangue utilizado foi doado por um adulto da mesma espécie, macho, clinicamente hígido, de cativeiro. O procedimento foi realizado de acordo com o prescrito pela clínica médica de pequenos animais, visto que, os relatos descritos na medicina de xenarthras são escassos. O resultado se mostrou satisfatório, com ausência de reações transfusionais tardias e melhora do quadro geral do paciente, o que demonstra a possibilidade da utilização de transfusão sanguínea em tamanduás como opção terapêutica.

Intestine vascularization of sloth (Bradypus variegatus SCHINZ, 1825) / Vascularização do intestino do bicho-preguiça (Bradypus variegatusSCHINZ, 1825)

Common sloth (Bradypus variegatus) is a mammal that belongs to the superorder Xenarthra, typical from neotropical regions, with geographic distribution from Honduras to northern Argentina. Our study aimed to describe the intestine blood supply of these Bradipodids in order to collaborate with the clinical-surgical for these animals. For that, ten animals, included four females and six males, were sampled from the collection of the Anatomy Division, Department of Animal Morphology and Physiology, Universidade Federal Rural de Pernambuco DMFA/UFRPE. Corpses received formalin, preserved in saline solution and subsequently dissected for description of the cranial (AMCr) and caudal (AMC) mesenteric arteries. Sixty percent of sloths presented AMCr and AMC, cwhile 30% of them had intestines (small and large) irrigation from the common mesenteric artery (AMCo), an arterial trunk from which AMCr and AMC originated. For 10% of the specimens, the entire intestine was vascularized only by AMCr. Along the AMCr branches, there were arched arrangements, with arches size reductionat the level of the small intestine. Therefore, B. variegatus presents anatomical variations regarding the irrigation of the intestine, which can be made from AMCr and AMC, from the AMCo arterial trunk or to a lower frequency exclusively through AMCr branches.

A preguiça-comum (Bradypus variegatus)é um mamífero pertencente à superordem Xenarthra, típica de regiões neotropicais, com distribuição geográfica de Honduras ao norte da Argentina. O estudo teve como objetivo descrever o suprimento sanguíneo do intestinodestes Bradipodídeos, com o intuito de colaborar com a clínica-cirúrgica destes animais. Neste contexto, foram utilizados dez animais pertencentes ao acervo da Área de Anatomia do Departamento de Morfologia e Fisiologia Animal da Universidade Federal Rural de Pernambuco DMFA/UFRPE, sendo quatro fêmeas e seis machos. Os cadáveres foram formolizados e conservados em solução salina e, posteriormente, dissecados para a descrição das artérias mesentéricas cranial (AMCr) e caudal (AMC). Diante disto, observou-se que 60% das preguiças apresentaram AMCr e AMC.Enquanto que, em 30% delas, a irrigação dos intestinos (delgado e grosso) se deu a partir da artéria mesentérica comum (AMCo), um tronco arterial do qual se originaram AMCr e AMC. E em 10% dos espécimes, todo intestino foi vascularizado unicamente pela AMCr. Ao longo das ramificações de AMCr percebeu-se arranjos arqueados, com diminuição do tamanho dos arcos ao nível do intestino delgado. Portanto, B. variegatusapresenta variações anatômicas quanto a irrigação do intestino, podendo esta ser feita a partir de AMCr e AMC, do tronco arterial AMCo ou numa menor frequência através exclusivamente de ramos de AMCr.

Descrição anatômica da artéria carótida externa e seus ramos na preguiça-comum / Anatomical description of external carotid artery and its branches in sloth

Bradypus variegatus, espécie pertencente à família Bradypodidae e à superordem Xenarthra, pode ser considerada modelo biológico de caráter multidisciplinar. Assim, realizou-se um trabalho de descrição anatômica da artéria carótida externa (ACE) e dos seus ramos no bicho-preguiça B. variegatus. Utilizaram-se 10 animais adultos, sendo todos fêmeas, que foram submetidos à dissecação, constatando-se que a artéria (a.) carótida comum se bifurca, em externa e interna, no nível do primeiro anel traqueal. A ACE, então, segue estendendo-se até a maxila, onde emite ramos para a região temporal e para o polo posterior do olho. Em todos os animais estudados, foram observados sete ramos principais da ACE, que, segundo a sua origem e localização, foram denominados como a. auricular, a. lingual, a. facial, a. alveolar, a. inferior, a. temporal, a. maxilar e a. oftálmica. Os ramos maxilar e oftálmico correspondem aos terminais e os demais são ramos colaterais. Em 50% dos animais analisados, foi verificada a presença de anastomoses arteriais e 40% deles apresentaram o acréscimo de um ramo aos principais. Desses, 30% demonstraram a presença de um ramo traqueal e 10% de um ramo sublingual, sendo esses ramos colaterais.(AU)

Bradypus variegatus is a species belonging to the family Bradypodidae and superorder Xenarthra, which should be considered as a multidisciplinary biological model. Thus, an anatomical description of the external carotid artery (ACE) and its branches in sloth B. variegatus was studied. Ten adult animals, all of them female, were submitted to dissection, and it was observed that the common carotid artery (a.) bifurcates in external and internal at the level of the first tracheal ring. Then, ACE extends through the maxilla where it launches branches to the temporal region and posterior eye side. For all sampled animals, seven principal branches of ACE were observed, and according to their origin and location were denominated as auricular, lingual, facial, bottom alveolar, temporal, maxillary and ophthalmic arteries. The maxillary and ophthalmic branches correspond to the terminals and the other branches are collateral. Presence of arterial anastomoses was observed in 50% of the sampled animals and 40% of them had increase of a branch on the principal. In these, 30% had presence of one tracheal branch and 10% of a sublingual branch, considering these branches as collateral.(AU)
