RESUMO. Os atropelamentos de animais silvestres têm recebido especial atenção dos pesquisadores nos últimos anos por se tratar da causa primária de morte em estradas. Contudo, estudos que abordem o tema ainda são escassos e, geralmente, tratam apenas de mamíferos. Diante disso, este estudo teve o objetivo de monitorar a mortalidade de animais silvestres por atropelamentos no trecho Campina Grande -Patos da BR-230 entre novembro de 2010 e novembro de 2011. Foram realizadas viagens mensais com duração média de 2h, percorrendo-se o trecho de carro. Foi comparado o número de atropelamentos no período seco e chuvoso, geral e por grupo. Os animais atropelados foram identificados até o menor nível taxonômico possível, descartando-se os animais domésticos. Foram registrados 188 espécimes de vertebrados atropelados, sendo Mammalia o mais amostrado (n=108; 57,4%). A espécie mais representativa foi Cerdocyon thous (n=87; 46,5%). O maior número de atropelamentos ocorreu no período seco. Quando comparado por grupo, porém, aves e répteis apresentaram um maior número de atropelamentos durante o período chuvoso. Cerdocyon thous, apresentou taxas de atropelamento maiores que em outros levantamentos realizados no Brasil (87 indivíduos, 46,5%), o que parece ser uma realidade local. Dentre os répteis atropelados, 70% corresponderam a espécies de serpentes, que pode estar relacionado ao deslocamento lento e necessidade de termorregulação desses animais e pelo fato de serem considerados "animais perigosos", levando ao extermínio intencional.

The trampling of wild animals have received special attention from researchers in recent years because it is the primary cause of death on roads. However, studies that address the topic are still scarce and generally deal only with mammals. Therefore, this study aimed to monitor the mortality of wild animals by trampling between Campina Grande and Patos in the BR-230 highway from November 2010 to November 2011. Were made monthly trips lasting 2 hours traveled by car. We compared the number of trampling in the dry and rainy period. The animals killed on roads were identified to lowest possible taxonomic level, discarding pets. We recorded 188 specimens of vertebrates' trampling, and the most sampled were mammals (n=108, 57.4%). The most

The common marmoset (Callithrix jacchus) are small primates belonging to the family Cebidae, subfamily Callitrichinae and are the most well-known and common in adaptation to captivity. The scarcity of data in the literature on the anatomy of these marmosets and wild animals hinders the application of appropriate anesthetic and surgical procedures and therapeutics. In order to understand the anatomic variations in the lobation and bronchopulmonary segmentation the lungs were dissected from nine adult common marmoset (Callithrix jacchus) corpses, five males and four females. In the marmosets, the right lung presented cranial lobe, middle lobe, caudal lobe and accessory lobe while the left lung presented cranial and caudal lobes. The fissures were very pro-eminent in both the lungs. The main right bronchus emitted independent branches, one for each lobe, and it followed in a straight line in the caudal lobe as a continuation of this bronchus and the same was observed in the main left bronchus. The bronchopulmonary segmentation in the right lung ranged from one to five branches in the cranial lobe; the middle lobe had a single branch; the caudal lobe had three to five branches and the accessory lobe had three branches. In the left lung the cranial lobe bronchopulmonary segmentation ranged from one to five branches while in the caudal lobe it was three to four branches.

RESUMO.A utilização de técnicas modernas para aplicação na área da reprodução cresce cada vez mais na medicina veterinária e com isso se fazem necessários estudos que avaliem a eficiência destas técnicas. Devido à localização cortical dos folículos dentro do ovário, a técnica mais adequada para obtenção dos oócitos caninos é o Slicing, o qual apresenta melhores resultados em relação a quantidade de oócitos coletados quando comparado com outras técnicas. Buscou-se com este estudo, verificar a qualidade dos oócitos coletados em ovários de cadelas e gatas com diferentes idades que foram submetidas à procedimento de Ovário Salpingo Histerectomia (OSH) no Hospital Veterinário da Universidade Federal de Campina Grande. Os oócitos foram classificados quanto a sua qualidade com relação a morfologia do complexo cumulus oophorus. A idade e a fase estral em que as cadelas e gatas se encontravam no momento da coleta não influenciou na qualidade e quantidade dos oócitos coletados.Palavras chave: cadelas, gatas, reprodução, slicing Obtaining oocytes in puppies and cats submitted to salpingooophorectomyABSTRACT. The use of modern techniques for application in the field of reproduction grows more and more in veterinary medicine and therefore studies are needed to evaluate the efficiency of these techniques. Due to the cortical location of the follicles within the ovary, Slicing is the most adequate technique to obtain canine oocytes, which presents better results in relation to the amount of oocytes collected when compared to other techniques. The aim of this study was to verify the quality of oocytes collected from ovaries of bitches and cats with different ages submitted to the Salpingo Ovary Hysterectomy (OSH) procedure at the Veterinary Hospital of the Federal University of Campina Grande. The oocytes were classified according to their quality in relation to the morphology of the cumulus oophorus complex. The age and estrus stage in which bitches and cats were at the time of collection did not influence the quality and quantity of oocytes collected.

Black-striped capuchin monkeys (Sapajus libidinosus) are diurnal omnivores found on the American continent and have the widest geographic distribution of the neotropical primates. 1 Constant deforestation means that these animals migrate to urban centers, becoming targets of predatory hunting and leading to a significant number of specimens in captivity.So that the veterinary physician can intervene efficaciously in the health of these animals, in addition to clinical knowledge, the choice of the chemical immobilization method of the animal, anesthesia and the anesthetic administration route is fundamental to the success of the procedures. 2The association of tiletamine-zolazepam (TZ) has been widely used in wild and exotic animals because it requires a small injection volume, is well absorbed intramuscularly, and has a wide safety margin and permits immobilization to anesthesia with minimum cardiopulmonary effect. 3,4 For most species, 2-5 mg/kg are sufficient to promote anesthesia for minimal procedures, but smaller species require a bigger dose. 2 However, the use of this association is still controversial in some species due to a lack of studies. AbstractBackground: Tiletamine-zolazepam is a widely used as an alternative chemical immobilization method in non-human primates, with a safe application pathway and necessary relaxation. In order to determine the electrocardiographic parameters of Sapajus libidinosus after intramuscular tiletamine-zolazepam administration at the dose of 5 mg/kg, nine animals were submitted to anesthesia. Methods:The interpretation of the electrocardiogram determined: heart rate in bpm and heart rhythm, P wave, P-R interval, R wave, QRS complex, T wave, Q-T interval, corrected QT interval and electrical axis. The mean HR was 206 ± 32 bpm. Results:The majority of the monkeys showed normal sinus rhythm, but one animal showed sinus tachycardia. The most commonly observed electrical axis was between +30° and +90°. Two animals presented bigger alterations in the tracing such as low amplitude QRS and T wave bigger than 1/4 of the R wave. Conclusions:The administration of tiletamine-zolazepam was safe and efficacious, with minimal cardiovascular effects. K E Y W O R D Sanesthesia, electrocardiogram, primate | 155 de LA SALLeS et AL.

RESUMO.As aves da ordem Psittaciformes estão entre as mais criadas como pet, o que consequentemente aumenta a procura por atendimento médico veterinário especializado em aves e, para tal, o estudo e conhecimento da anatomia destes animais se torna essencial. De outra forma, a morfologia craniana é fundamental na identificação de espécie de animais com características morfológicas externas semelhantes. Buscou-se obter dados referentes ao crânio de Diopsittaca nobilis, para contribuir com o conhecimento anatômico desta espécie. O presente estudo foi realizado com 3 crânios de Diopsittaca nobilis, que foram preparados através de dissecação e maceração controlada com água. Apesar do processo natural de fusão, puderam ser identificados ossos e estruturas do crânio com suas particularidades. Realizou-se também mensurações dos crânios, onde a média da largura máxima do crânio foi de 28,70mm e do comprimento do crânio sem a ranfoteca foi de 36,16mm. Os dados obtidos contribuem para a melhor caracterização da espécie.Palavras chave: Anatomia, psittacidae, crânio Anatomical and morphometric aspects of the Diopsittaca nobilis Linnaeus, 1758ABSTRACT. The birds of the order Psittaciformes are among the most created as pet, which consequently increases the demand for specialized veterinary care in birds and, for this, the study and knowledge of the anatomy of these animals becomes essential. Otherwise, cranial morphology is fundamental in the identification of species of animals with similar external morphological characteristics. We sought to obtain data regarding the skull of Diopsittaca nobilis, to contribute with the anatomical knowledge of this species. The present study was performed with 3 skulls of Diopsittaca nobilis, which were prepared by dissection and controlled maceration with water. Despite the natural process of fusion, bones and structures of the skull could be identified with their particularities. Measurements were also made of the skulls, where the mean maximum width of the skull was 28.70mm and the length of the skull without the ranogram was 36.16mm. The data obtained contribute to the better characterization of the species.

The objective of the present study was to monitor and characterize morphological alterations in ovaries of agouti (Dasyprocta prymnolopha), reared in captivity, by using abdominal ultrasonography. All animals underwent daily vaginal cytological examination to identify the current cycle phase. For each phase of the estrous cycle, ultrasound examinations were carried out to identify and describe the morphology of both ovaries. Topographic parameters in an ultrasound window were established to locate the ovaries. The agouti estrous cycle lasted an average of 29.94 ± 6.77 days. During vaginal cytology examinations, all cell types were identified, and each phase of the estrous cycle was established by cell counts. No significant alterations were observed in the assessed ovarian morphometry measurements. In 75% of the animals examined, ovarian follicle presence was observed in the proestrus phase.

Background: Brown-throated sloths are mammals of the order Xenarthra, suborder Pilosa, family Bradypodidae. These folivorous and arboreal animals, which possess a peculiar type of arboreal quadrupedalism, move through the forest canopy by means of suspensory locomotion. On the ground, their extremely slow movements make them easy targets for road accidents, often leading to serious injury or even death. This paper describes the forelimb muscles of the brown-throated sloth (Bradypus variegatus), updating the literature on the subject to help veterinarians in clinical and surgical interventions on this species, and to provide data for comparative animal anatomy.Materials, Methods & Results: Five brown-throated sloths (Bradypus variegatus Schinz, 1825), two adults and three babies were dissected. The animals were donated by the Arruda Câmara Zoo and Botanical Park in João Pessoa, state of Paraíba, Brazil, where they were thawed and fixed in 10% formalin. The sloths’ forelimbs were dissected by lifting and folding over a skin flap to expose, identify and describe the underlying musculature. The dissection revealed the following muscles: supraspinatus, infraspinatus, deltoideus, teres major, subscapularis, coracobrachialis, brachialis, biceps brachii, triceps brachii, anconeus epitrochlearis, dorsoepitrochlearis, brachioradialis, supinator, pronator teres, pronator quadratus, extensor carpi radialis, extensor carpi ulnaris, extensor carpi obliquus, flexor carpi radialis, flexor carpi ulnaris, extensor digitorum communis, extensor digitorum lateralis, palmaris longus, flexor digitorum superficialis, flexor digitorum profundus, extensor indicis longus second finger, extensor indicis brevis second finger, extensor digitorum third finger, abductor digitorum second finger, abductor digitorum third finger, palmaris brevis, and interosseous muscles. Characteristics found in this species revealed differences in the muscular development of the upper forelimb, whose muscles are less developed than those of the lower forelimb, which are visibly more developed with greater muscle density. An interesting feature of this musculature is the presence of three flexor tendons, short and thick, originating from the flexor muscles, which give the hand of the brown-throated sloth a hook-like aspect.Discussion: Our observations indicate that some of the muscles are very similar to those of other animals of this order and also of domestic mammals. However, the most relevant characteristics resemble those of arboreal animals and humans, since the forearm and hand pronation and supination muscles are essential for their arboreal habits. Therefore, all the pronator and supinator muscles of the brown-throated sloth are well developed. Due to the functional adaptations of the species of the family Bradypodidae, the shoulder muscles, especially the deltoideus, are more developed, providing greater support to the shoulder joint, and their origin and insertion assist in faster and easier movements, albeit exerting less force. The group of flexor muscles in this species gives the forearm stronger and more concentrated action than the extensor muscles. This study enabled us not only to produce a more precise description of the muscles of the forelimb of this species but also to update the literature, since there are few relevant studies on the subject and the terms in the literature are outdated and no longer in use.

Background: Amebiasis is a parasitic infection caused by obligate or facultative amoeboid protozoans, as well as free-living forms. The genus Entamoeba includes both pathogenic and commensal species that can affect humans and animals. Entamoeba histolytica is the most important species associated with intestinal and extraintestinal infections in humans, while Entamoeba invadens is considered the most common and serious pathogen to many reptile species, including lizards, snakes and crocodilians. The aim of this manuscript is to report a case of amebiasis in a backyard red-foot tortoise in northeastern Brazil.Case: A 10-month-old male red-foot tortoise (Chelonoidis carbonaria) was presented at the Animal Pathology Laboratory of the Veterinary Hospital of Federal University of Campina Grande for necropsy with a 1-week history of anorexia, apathy, and reluctance to move. According to the owner, the animal suffered from heat stress in the backyard, where it was housed with another male red-foot tortoise. At post-mortem examination, there were approximately 1 mL of yellowish viscous transudate in the coelomic cavity. The liver was large, with rounded edges and multifocal to coalescing yellowish areas in the subcapsular surface. When cut, the parenchyma was more friable and yellowish. At the opening of the small intestine, the mucosa was thickened, reddened, and contained many variably sized, dark red ulcers with depressed and hemorrhagic centers. Histopathology of the liver reveals diffuse macro and microvacuolar degeneration of the hepatocyte cytoplasm, often displacing the nucleus peripherally (fatty degeneration). There were extensive and multifocal areas of necrosis characterized by shrunken, hypereosinophilic and pyknotic hepatocytes. Amebic trophozoites were seen through the areas of necrosis and degeneration and the morphological features were suggestive of the genus Entamoeba. In the portal triads and slightly extending to the sinusoidal spaces, there is a moderate inflammatory infiltrate of macrophages, lymphocytes, plasma cells and rare heterophils. There were amebic trophozoites and thrombi in hepatic vessels, and mild intracanalicular cholestasis. The small intestine contained areas of transmural necrosis and ulceration associated with inflammatory infiltrate of macrophages, lymphocytes and plasma cells. The ulcers were covered by a thick fibrinonecrotic exudate mixed with a varying number of heterophils and macrophages. The submucosa contained hemorrhage and edema. Similar amebic trophozoites were found within the mucosa and submucosa, and also detected in the lumens of blood vessels at the submucosa. The amebic trophozoites, seen in the liver and intestine, were intensely Periodic acid–Schiff positive.Discussion: The diagnosis of amebiasis was based on the epidemiological, clinical and anatomopathological findings. Amebiasis is a well-recognized disease that usually is diagnosed post-mortem in numerous species of reptiles. Unfortunately, there are no scientific articles describing these cases in Brazil. In reptiles, the major pathogenic specie is Entamoeba invadens, while several other species are considered non-pathogenic, such as E. barreti, E. insolita, E. terrapinae, E. ctenosaurae, and E. knowlesi, among others. Although cultivation of E. invadens was not undertaken, the anatomopathological findings and the morphological appearance of the agent is highly suggestive of infection with this organism. In conclusion, amebiasis is a severe infectious disease that can affect young red-footed tortoises under adverse environmental conditions. Clinical signs are nonspecific and may be difficult to identify. The diagnosis is usually made post-mortem by anatomopathological findings and the morphological appearance of the agent.
