Chronic lead intoxication in a jaguar (Panthera onca) shot with round lead pellets: case report / Intoxicação crônica por chumbo em uma onça pintada (Panthera onca) alvejada com projéteis de chumbo: relato de caso

Lead is a heavy metal and an important cause of acute or chronic toxicosis in humans, domestic, and wild animals. This report aims to describe a case of chronic lead poisoning in a jaguar (Panthera onca) kept under human care that was rescued from the wild environment. The animal was rescued in poor condition in 2004 and kept under human care at the Belo Horizonte Zoological Garden (Minas Gerais, Brazil) until 2020, when it presented with anorexia, vomiting and ataxia. Over the past years the animal had episodes of anemia and increased serum urea and creatinine. Radiography demonstrated 21 radiopaque projectiles on the right side of the face. At necropsy there were multiple projectiles surrounded by fibrous tissue in the subcutaneous of the right side of the face, fibrinous peritonitis, multiple gastric ulcers, and melena. The lead dosage was performed using the atomic absorption spectrometry technique using renal tissue collected at necropsy, with a result of 908 ppb (µg/kg). The findings of projectiles associated with the dosage of lead above the reference limits allow the diagnosis of chronic intoxication in this case.

Chumbo é um metal pesado e uma causa importante de toxicose crônica no homem e em animais domésticos e selvagens. Este relato teve como objetivo descrever um caso de intoxicação crônica por chumbo em uma onça-pintada (Panthera onca), mantida sob cuidados humanos, que foi resgatada de seu ambiente natural em 2004, em pobre condição corporal. O animal foi encaminhado ao zoológico de Belo Horizonte (MG, Brasil), onde permaneceu até 2020, quando desenvolveu anorexia, vômitos e ataxia. Durante os últimos anos, o animal teve episódios de anemia e aumento da concentração sérica de ureia e creatinina. O exame radiográfico demonstrou 21 projéteis radiodensos na face direita. À necropsia, foram observados vários projéteis envoltos por tecido conjuntivo no subcutâneo da face esquerda, peritonite fibrinosa, múltiplas úlceras gástricas e melena. A concentração de chumbo foi determinada por espectrometria de absorção atômica em amostras de tecido renal, indicando 908 ppb (µg/kg). O achado de projéteis de chumbo associado à elevada concentração de chumbo é compatível com intoxicação crônica por chumbo neste caso.

The alien synanthropic Salticidae in Brazil (Araneae) / As aranhas Salticidae exóticas sinantrópicas no Brasil (Araneae)

Salticidae is the most diverse family of Araneae and in Brazil, there are 667 species. Among these species, five are synanthropic exotics: Plexippus paykulli (Audouin, 1826), Hasarius adansoni (Audouin, 1826), Menemerus bivittatus (Dufour, 1831), M. nigli Wesolowska & Freudenschuss, 2012 and Thyene coccineovittata (Simon, 1886). To understand the current distribution of these species in Brazil, seven collections of 643 lots were examined from seven Brazilian zoological collections. The synanthropic exotic species with the highest records were Plexippus paykulli, Menemerus bivittatus, and Hasarius adansoni, generally collected and associated with human dwellings and buildings. They are present in all regions (North, Northeast, Midwest, and South macro-regions), with the largest region, in all regions of the country in 22 states and 98 municipalities, followed by Hasarius adansoni in 17 states and 88 municipalities, Menemerus bivittatus in 19 states and 68 municipalities. Menemerus nigli and Thyene coccineovittata are from recent introductions that occurred in the city of Rio de Janeiro, Rio de Janeiro, Brazil.(AU)

Foram examinados 643 lotes destas cinco espécies no Brasil, depositados em sete coleções zoológicas brasileiras. As espécies exóticas sinantrópicas com maior número de registros foram Plexippus paykulli, Hasarius adansoni e Menemerus bivittatus, na maioria dos casos coletadas associadas a habitações e edificações humanas. Elas estão presentes em todas as macrorregiões do país (Norte, Nordeste, Centro-Oeste, Sudeste e Sul), sendo P. paykulli a que possui a maior distribuição, ocorrendo em 22 estados e 98 municípios, seguido de H. adansoni em 17 estados e 88 municípios e M. bivittatus em 19 estados e 68 municípios. Menemerus nigli e Thyene coccineovittata, são introduções recentes, ocorrendo apenas na cidade do Rio de Janeiro, Rio de Janeiro, Brasil.(AU)

Utilização de filamentos de ouro em pontos de acupuntura em lobo-guará (Chrysocyon brachyurus) com espondilose / Use of gold filaments in acupuncture points in maned wolf (Chrysocyon brachyurus) with spondylosis / Implantación de filamentos de oro en puntos de acupuntura en aguará guazú (Chrysocyon brachyurus) com espondilosis

Um lobo-guará (Chrysocyon brachyurus) macho com 15 anos de idade apresentou dificuldade ao se levantar e deitar, relutância ao caminhar e aspecto arqueado da coluna vertebral. Após contenção química, o paciente foi examinado e submetido a exames radiográficos e colheita de material biológico para análises laboratoriais. Os resultados dos exames apontaram um animal saudável, porém visualizaram-se espondiloses em coluna vertebral na região cervical e torácica. Foi iniciado protocolo para controle de dor, inflamação e uso de regenerador articular, a fim de estabilizar o quadro do paciente. Novo manejo foi agendado para implante de filamentos de ouro em pontos de acupuntura. Após essa terapia, o paciente foi acompanhado pela equipe veterinária, e alguns dias após o tratamento houve melhora do quadro clínico o animal deixou de apresentar dificuldade para caminhar, deitar, levantar e ficar em estação. O paciente retornou ao recinto, dividindo o local com a fêmea, e até o momento está assintomático.(AU)

A 15-year-old male maned wolf (Chrysocyon brachyurus) showed difficulty getting up and lying down, reluctance to walk and an arched aspect of the spine. After chemical containment, the patient underwent physical examination and was submitted to radiographic examens and collection of biological material for laboratory analysis. The test results indicated a healthy animal, but spondylosis was seen in the cervical and thoracic spine. A protocol was started to pain control, inflammation, and use of condroprotective to stabilize the patient's condition. A new management was scheduled for the implantation of gold filaments in acupuncture points. After this therapy, the patient was followed up by the veterinary team, and days after the treatment, there was an improvement in the clinical condition- the animal had no more difficulty walking, lying down, getting up and standing still. The patient returned to the enclosure, sharing the place with the female, and so far, the clinical signs presented are absent and/or reduced.(AU)

Un aguará guazú (Chrysocyon brachyurus) macho de 15 años mostró dificultad para levantarse y acostarse, renuencia a caminar y un aspecto arqueado de la columna vertebral. Después de la contención química, el paciente fue examinado y sometido a exámenes radiográficos y recolección de material biológico para análisis de laboratorio. Los resultados de la prueba indicaron un animal sano, pero se observó espondilosis en la columna cervical y torácica. Se inició protocolo de control del dolor, inflamación y uso de protectores articulares, con el fin de estabilizar el estado del paciente. Con el objetivo de brindar una mejor calidad de vida, ya que se trata de un animal salvaje, incapaz de realizar ordinariamente terapias invasivas, se implantaron filamentos de oro en puntos de acupuntura. Posteriormente a esta terapia, el paciente fue acompañado por el equipo veterinario, y dias después del tratamiento hubo una mejoría en el estado clínico - el animal no tuvo dificultad para caminar, acostarse, levantarse y estar de pie. El paciente regresó al recinto, compartiendo el lugar con una hembra, y hasta el momento los signos clínicos anteriormente presentados están ausentes y/o reducidos.(AU)

Avian mycobacteriosis in a naturally infected captive nocturnal curassow (Nothocrax urumutum)

A senile female nocturnal curassow (Nothocrax urumutum) kept under human care was found dead. Grossly, the lungs were congested and had a nodule with 2.0 cm in diameter adhered to the left lung. Histologically, there were multifocal to coalescent areas of necrosis characterized by deposition of amorphous and eosinophilic material with large amount of cellular debris, surrounded by numerous epithelioid macrophages, multinucleated Langhans giant cells, occasional lymphocytes and plasma cells. Ziehl-Neelsen stained sections demonstrated myriad of intralesional alcohol-acid resistant bacilli (BAAR). DNA extracted from lung samples were evaluated by nested polymerase chain reaction resulting in mycobacterial DNA identification. This is the first reported case of mycobacteriosis in a nocturnal curassow.(AU)

Biliary cystadenoma in a lion (Panthera leo)

Animals in human care often exceed the life expectancy of animals in the wild when they have veterinarian follow-ups, no competition for space or food, and continuous care. Advanced age favors the development of mutations that often trigger cancer, which sometimes causes death. There are reports in the literature on neoplasms in lions in the liver, which are one of the main organs affected. A 20-year-old lion specimen was received for necropsy at the Federal University of Paraná, Curitiba, Brazil. Multiple cystic dilations were observed in the liver. Histologically, they were internally covered by a simple cuboidal epithelium, similar to that observed in the bile ducts, without cellular atypia. The adjacent liver parenchyma presented with mild disorganization of the hepatocyte cords. Biliary cystadenomas are benign growths formed by a thin opaque capsule filled with a slightly yellowish translucent fluid compressing the adjacent liver parenchyma, as highlighted in this case. The epithelium of the cysts was positive for anti-cytokeratin (CK) (EIA/A3E) and anti-CK7, confirming histogenesis in the bile ducts. This study reports a case of biliary cystadenoma in a Panthera leo specimen.(AU)

Seminoma in a gray brocket deer (Mazama gouazoubira) with unilateral cryptorchidism

Cryptorchidism is the incomplete descent of the testes and associated structures, and cryptorchid testes are more likely to develop testicular neoplasms, such as seminoma. This is the first report of a seminoma in a cryptorchid wild-caught gray brocket deer (Mazama gouazoubira). The animal developed a unilateral seminoma with classical histopathological findings and benign behavior. Six months after the orchiectomy the cervid presented a metatarsal opened fracture, dying during the orthopedic surgery. No macro or micrometric metastasis was observed at the necropsy.(AU)

Toxoplasmosis in black-faced lion tamarin (Leontopithecus caissara) / Toxoplasmose em mico-leão-de-cara-preta (Leontopithecus caissara)

Neotropical primates are susceptible to several parasitic diseases, the most relevant of which is toxoplasmosis. The black-faced lion tamarin is one of the most endangered callitrichid, with no more than 400 individuals in the wild. A young specimen of black-faced lion tamarin died acutely after being rescued and sent to the Sorocaba Zoological Park. This is the first report of acute fatal toxoplasmosis in L. caissara in Brazil.

Os primatas neotropicais são suscetíveis a inúmeras enfermidades parasitárias, sendo a mais relevante a toxoplasmose. O mico-leão-de-cara-preta é um dos calitriquídeos mais ameaçados no mundo, com aproximadamente 400 indivíduos em estado selvagem. Um exemplar de mico-leão-de-cara-preta, jovem veio à óbito de forma aguda após ser resgatado e enviado ao Zoológico do interior de São Paulo. Este é o primeiro relato de toxoplasmose aguda fatal em L. caissara no mundo.

Ilha Grande, one of the locations with the most records of bat species (Mammalia, Chiroptera) in Rio de Janeiro state: results of a long-term ecological study

Abstract Faunal inventories provide quantitative and qualitative data for different sites and are relevant sources of information for identifying areas of high species richness and endemism. Biological collections are important in this context for increasing the precision of species identification. The objectives of this study were to update the list of bat species of Ilha Grande by analyzing specimens in zoological collections as well as records obtained in areas where no such studies had been undertaken before; to compare five different studies conducted on Ilha Grande using mist net sampling; and to compare the results of studies on Ilha Grande with sampling results from other areas in Rio de Janeiro state. The occurrence of 36 bat species was confirmed for Ilha Grande. Five studies on Ilha Grande formerly conducted by the authors were compared with 34 fauna inventories in Rio de Janeiro state. The studies on Ilha Grande had distinct objectives and sampling techniques applied to different locations in the same area. Ilha Grande is one of the regions in Rio de Janeiro state with more bat records both in terms of abundance and number of species, as well as one of the areas of highest bat capture effort.

Taxonomic key to the snakes (Squamata: Ophidia) species of the Itajaí Valley, Santa Catarina, Brazil

Abstract Snakes represent the richest Reptile group in Brazil, amounting to 412 species and 40% of them are endemic for the country. This great richness combined with the poor taxonomic knowledge makes the identification a difficult process. To correctly identify a specimen, guides, taxonomic revisions, identification keys, and consulting specialists are the most used methods. Identification keys are based on separation and segregation of characters, where the chosen paths lead to the appropriate taxa. These tools are normally used by students and non-taxonomists. Also, they can be very helpful with the general public, where they can identify the species with simple characters. This study aims to develop keys for the snakes from the State of Santa Catarina state, Brazil, focusing on the Itajaí Valley species. We surveyed 351 specimens deposited in Universidade Regional de Blumenau Zoological Collection (CZFURB), Universidade Federal de Santa Catarina (CHUFSC), and Natural History Museum of Capão da Imbuia (MHNCI) herpetological collections. Characters including pholidosis, dentition, and coloration patterns were examined from the 46 snake species registered from Itajaí Valley.

An unusual large polythene bezoar in the rumen of a fallow deer (Dama dama)

Ingestion of indigestible foreign bodies in both domestic and wild ruminants are very common. Indigestible foreign materials can be ingested during free range grazing or under captivity in zoos or game parks. There are different types of bezoars in literature. The most common in animals are phytobezoars, trichobezoars, lactobezoars, phytotrichobezoars, lithobezoars or pharmacobezoars. This is a case study of an adult (4 years old), 40 kg body weight female Fallow Deer (Dama dama) which was reared with other four more Fallow Deer does at Riyadh Zoological Garden. The doe was found sluggish and weak. On presentation the veterinarian of the zoo noticed the anorexia, pale mucous membranes and dullness. There was Normocytic Normochromic anaemia, low RBCs and Haematocrit level, high neutrophil count and leucocytosis. The doe was subjected to medicinal and supportive therapy but she could not recover and found dead on very next day. On post-mortem examination, an unusual large polythene bezoar along with calcified stony mass recovered from the rumen. The results suggested that the rumen impaction in the Fallow Deer might be due scavenging on refused Plastic dumps in the premises left over by visitors to the zoo and that the blood biochemical alterations, alongside clinical signs, might be of some diagnostic assistance.(AU)
