RESUMO
Histopathological and immunohistochemical methods were used to diagnose round cell tumors in 2 subantarctic fur seals Arctocephalus tropicalis with marked anemia. Although wild-born, both individuals were placed under human care while juveniles in a Brazilian aquarium. Both pinnipeds were PCR tested for herpesvirus, and 1 was infected with otariid gammaherpesvirus 5 (OtHV-5), previously described in a subantarctic fur seal stranded in Brazil. Although some gammaherpesviruses can cause sarcomas and other neoplasms, it was not possible to definitively associate OtHV-5 with the neoplasm. To our knowledge, these are the first neoplasm records in subantarctic fur seals.

Among pinnipeds, four Otariidae species (eared seals) have been reported as occasional or frequent vagrants along the coast of Brazil, mainly in the southern region. These animals usually arrive debilitated during winter and are directed to rehabilitation. Nevertheless, available information on sanitary aspects of stranded pinnipeds in Brazil is limited. Increased fur seal strandings (n=23) were recorded during the 2018 winter season in southeast Brazil (Iguape, Ilha Comprida, and Ilha do Cardoso, Sao Paulo State) compared to 2017 (n=2). Of these 23 fur seals, two were found dead and were in a good postmortem condition, and four died during rehabilitation and were subsequently necropsied. The remaining fur seals were not analyzed due to advanced decomposition (9/23) or successful rehabilitation (8/23). Herein, we report the antemortem hematology (n=4) and postmortem pathologic, parasitologic, and molecular analysis results as well as the most likely cause of stranding and/ or death (CSD) in five free-ranging juvenile South American fur seals (Arctocephalus australis) and one free-ranging juvenile subantarctic fur seal (Arctocephalus tropicalis). All animals were males, and all but one had poor body condition. Pathologic examinations revealed a variety of lesions, predominantly hemodynamic disturbances, endoparasitism, and inflammatory disease processes of suspected infectious nature. Molecular analyses detected gammaherpesvirus infections in two South American seals and one subantarctic fur seal, Sarcocystis sp. in one subantarctic fur seal, and Neospora spp. in two South American fur seals. All seals were PCR-negative for morbillivirus, flavivirus, and Toxoplasma gondii. The most likely CSDs were: starvation (2), aspiration pneumonia (1), asphyxia (1), predator attack (1), and presumed systemic infectious disease (1). These findings expand the geographic range of various pathogens of pinnipeds and may be of value to first responders, clinicians, and diagnosticians.

In 2017, an adult male South American sea lion (Otaria byronia), presenting emaciation and a cervical abscess, stranded alive in Florianópolis, southern Brazil. The animal was directed to a rehabilitation center, dying a few days later. On necropsy, the main gross findings were necrotizing lymphadenitis of the right prescapular lymph node and nodular bronchopneumonia. A novel alphaherpesvirus, tentatively named Otariid alphaherpesvirus 1, was amplified in several tissue samples. No histopathologic findings associated with viral infection were observed. Additionally, pulmonary tuberculosis by Mycobacterium pinnipedii was diagnosed by histopathological, immunohistochemical, and molecular techniques. Several bacteria were cultured from antemortem and postmortem samples, including Proteus mirabilis from the cervical abscess and cardiac blood, and Escherichia coli from the cervical abscess and pericardial effusion. Flavivirus, morbillivirus, and Apicomplexa were not detected by molecular techniques. Herein, we report a novel alphaherpesvirus in a pinniped species of the family Otariidae. Although previously described in Southern Hemisphere pinniped species, including South American sea lions, there is limited information regarding M. pinnipedii impact over this group. Further research is required to determine the associated pathogenesis of this novel herpesvirus, and prevalence of Otariid alphaherpesvirus 1 and M. pinnipedii in the reproductive colonies.

In ex situ conditions, little is known about the reproductive biology of meerkats. The aim of present study was to describe the morphological aspects of male genital organs and accessory glands using macroscopic evaluation, ultrasonography, and radiography, as well as describing semen characteristics post-electroejaculation. The results indicated anatomical characteristics of meerkats are very similar to those of cats, having a prostate, accessory bulbourethral glands, and an elongated and radiopaque structure in the penis, which is indicative of there being a baculum. The testicular volume was 0.81 cm³ (± 0.10) and the relative testis weight was 1.37 cm³/kg (± 0.15). Both testicles are present in the scrotum, which has an ellipsoidal shape, homogeneous texture, hypoechoic parenchyma and are encased in a hyperechoic tunica albuginea. Electroejaculation was effectively induced in all animals for semen collection with utilization of medetomidine and ketamine. The values semen samples variables were as follows for volume - 0.125⯱â¯0.193â¯mL, motility - 19.8⯱â¯18.6 %, vigor - 1.9⯱â¯1.0, concentration - 40.5⯱â¯25.2â¯×â¯106 sperm/mL and morphologically normal sperm - 10.8⯱â¯6.6 %. This is the first study in which there is a description of morphological and imaging aspects of the male reproductive tracts of meerkats, as well as the seminal characteristics after using electroejaculation for semen collection. Knowledge of anatomical and seminal characteristics is essential for implementation of assisted reproduction programs, as well as reproductive management in the species.

The protozoans Toxoplasma gondii and Sarcocystis spp. (Sarcocystidae: Apicomplexa) affect a wide variety of vertebrates. Both have been reported to infect pinnipeds, with impacts on health ranging from inapparent to fulminant disease and death. However, little is known regarding their infections and associated pathology in South American pinnipeds. We used histological techniques to survey for the presence of T. gondii and Sarcocystis spp. in 51 stranded pinnipeds from Brazil. Immunohistochemical and molecular assays were employed in those cases consistent with Sarcocystidae infection. T. gondii cysts were detected in the central nervous system and heart of a South American fur seal Arctocephalus australis, associated with meningoencephalitis, myocarditis and endocarditis, and confirmed by immunohistochemistry. Additionally, this animal presented Sarcocystis sp. cysts in brain and heart tissues. Four additional specimens-2 Subantarctic fur seals A. tropicalis, an Antarctic fur seal A. gazella and another South American fur seal-presented intrasarcoplasmic cysts compatible with Sarcocystis spp. in muscle samples. There was no inflammation associated with the Sarcocystis spp. tissue cysts and all cysts were negative for S. neurona immunohistochemistry. The B1 gene of T. gondii was amplified in the 5 pinnipeds infected by Sarcocystidae protozoans. To our knowledge, this is the first report of toxoplasmosis in wild South American pinnipeds and of Sarcocystis spp. in South American fur seals. Detection of terrestrial parasites in aquatic mammals could be an indicator of their presence in the marine environment.

A juvenile subantarctic fur seal (Arctocephalus tropicalis) found dead in Santa Catarina state, southern Brazil, presented with disseminated verminous pneumonia due to Parafilaroides sp. A concomitant infection with two different gammaherpesviruses was identified by PCR in different tissues; one of them possibly a novel species (tentatively named Otariid herpesvirus 7). Sarcocystis sp. DNA was identified molecularly in skeletal muscle samples with intrasarcoplasmic bradyzoites and no apparent tissue response. All analyzed samples (mandibular, laryngeal, tracheal, and mesenteric lymph nodes, and lung) were PCR-negative for Brucella spp. The most likely cause of death was severe pulmonary parafilaroidiasis. The pathogenic role of the gammaherpesviruses in several of the tissues was not evident. This study describes the pathogenicity of Parafilaroides sp. in a subantarctic fur seal, widens the host range of herpesvirus in pinnipeds, and reports the first molecular identification of Sarcocystis sp. in this species.

Resumo Um lobo-marinho-subantártico (Arctocephalus tropicalis) juvenil foi achado morto no Estado de Santa Catarina, sul do Brasil, apresentando pneumonia parasitária disseminada por Parafilaroides sp. Infecção concomitante por dois gammaherpesvírus diferentes foi identificada pela PCR em diversos tecidos, um desses herpesvírus possivelmente uma nova espécie (denominada provisoriamente Otariid herpesvirus 7). DNA de Sarcocystis sp. foi identificado molecularmente em amostras de músculo esquelético que apresentavam bradizoítos intra-sarcoplasmáticos sem aparente resposta tecidual. Todas as amostras analisadas (linfonodo mandibular, laríngeo, traqueal e mesentérico, e pulmão) pela PCR para Brucella spp. foram negativas. A causa mais provável da morte do animal foi parafilaroidose pulmonar severa. O papel patogénico dos gammaherpesvírus em vários tecidos não foi evidente. Este estudo descreve a patogenicidade de Parafilaroides sp. em um lobo-marinho-subantártico, amplia a variedade de hospedeiros de herpesvírus em pinípedes e reporta a primeira identificação molecular de Sarcocystis sp. para essa espécie.

Superficial mycoses are commonly reported in captive pinnipeds, usually maintained in wet and warm environments, favorable to fungal growth. Most superficial mycoses in pinnipeds have been described as difficult to treat; however, the majority of the reports come from past decades. Cutaneous lesions associated with opportunistic Fusarium sp. infections have been previously recognized in this taxon. We described the clinical signs, associated lesions and diagnosis (thermography, imprint cytology, histopathology, culture, electron microscopy, PCR) of a fusariosis case by Fusarium sp. in the nails and skin of an adult male captive South American sea lion (Otaria flavescens) recently transferred from another zoological institution, and its successful long-term treatment with Ketoconazole PO (60 days) and Miconazole solution spray TO, followed by Itraconazole PO (30 days). Herein we provide a successful approach to the diagnosis and treatment of fusariosis.

BACKGROUND: Tuberculosis is widely known as a progressive disease that affects endothermic animals, leading to death and/or economical losses, while mycobacterial infections in amphibians are commonly due to nontuberculous mycobacteria. To the authors' knowledge, this report describes the first case of bovine tuberculosis in a poikilothermic animal. CASE PRESENTATION: An adult female captive American bullfrog (Lithobates catesbeianus Shaw, 1802) died in a Brazilian aquarium. Multiple granulomas with acid-fast bacilli were observed in several organs. Identification of Mycobacterium bovis was accomplished by culture and PCR methods. The other animals from the same enclosure were euthanized, but no evidence of mycobacterial infection was observed. CONCLUSIONS: The American bullfrog was introduced in several countries around the world as an alternative husbandry, and its production is purposed for zoological and aquarium collections, biomedical research, education, human consumption and pet market. The present report warns about an episode of bovine tuberculosis in an amphibian, therefore further studies are necessary to define this frog species' role in the epidemiology of M. bovis.

An adult male Amazonian manatee Trichechus inunguis under human care presented with 3 circular cutaneous lesions on the dorsal aspect of the rostrum and between the nostrils (plenum). Initially these lesions were superficial, hypopigmented, without warmth and non-painful. Microbiological cultures of skin swabs isolated Candida sp. and Pseudomonas aeruginosa, and topical treatment with antiseptic, antifungal, anti-inflammatory and antibiotic medication was instituted. This treatment strategy did not lead to any clinical improvement, and after 6 mo, the lesions progressed to a confluent abscess (5.0 × 3.0 cm) with increased temperature and obvious discomfort on palpation. An impression smear of a cutaneous biopsy was submitted for Ziehl-Neelsen staining and after detection of acid-fast bacilli, the cutaneous biopsy and a swab from the lesion were sent for histopathology, culture and sensitivity testing. After 5 d of incubation and through PCR-restriction analysis of the isolates, Mycobacterium fortuitum and M. abscessus were identified. Sensitivity testing indicated that the isolates were susceptible to ciprofloxacin and clarithromycin, and after draining of the lesion and administration of systemic antibiotic treatment, there was rapid clinical improvement. This report describes non-healing lesions in an aquatic animal and illustrates the importance of evaluating the presence of non-tuberculous mycobacteria, opportunistic pathogens which are ubiquitous in the aquatic environment, in protracted, non-responsive cases. We also highlight the importance of a correct diagnosis and treatment approach, and we review concerns that these bacteria are zoonotic agents and are frequently resistant to conventional antibiotics.

The sound producing apparatus of the dwarf sperm whale (Kogia sima) presents a complex anatomic structure composed of melon, spermaceti, phonic lips, vocal cap, case, papillae, spermaceti chamber and other airspaces, as well as facial muscles involved in sound production. The spermaceti chamber rests on the caudal portion of the premaxilla, with part of its mucosa covered with spherical/oval-shaped structures (approximately 1 to 2 mm in diameter), compatible with vesicles (previously referred to as "papillae"). Macroscopical examination revealed whitish, firm, widely and irregularly distributed vesicular mucosa on the premaxillary portion of the spermaceti chamber of a K. sima specimen stranded on the coast of Santos (southeastern Brazilian coast). Upon microscopic examination, walls of connective tissue with abundant type I collagen forming vesicles with an internal space or cavity filled with a small amount of eosinophilic substance compatible with mucoproteic fluid were observed. The base of such vesicles presented glands within the connective tissue, probably responsible for fluid production. This study describes the histology of the mucosa of the spermaceti chamber of a K. sima specimen and characterizes the glands associated with fluid production.(AU)
O sistema de produção sonora do cachalote-anão (Kogia sima) apresenta uma complexa estrutura anatômica composta por melão, espermacete, lábios fônicos, "vocal cap", "case", papilas, câmara do espermacete e outros espaços aéreos, além de músculos faciais envolvidos na produção sonora. A câmara do espermacete localiza-se na porção caudal da pré-maxila, apresentando parte de sua mucosa recoberta por estruturas esférico-ovaladas de aproximadamente 1 a 2 mm de diâmetro, compatíveis com vesículas (previamente denominadas "papilas"). Ao exame macroscópico de um espécime de K. sima encalhado no litoral de Santos (sudeste da costa brasileira), foi identificada mucosa esbranquiçada e firme ao corte, ampla e irregularmente distribuída na porção pré-maxilar da câmara do espermacete. Ao exame microscópico foram observadas vesículas compostas por abundante tecido conectivo de colágeno tipo I, dando origem a um espaço interno ou cavidade, contendo pequena quantidade de substância eosinófila, compatível com fluido mucoprotêico. Estruturas glandulares foram observadas em tecido conjuntivo na base das vesículas, provavelmente responsáveis pela produção do fluido observado no interior das mesmas. Esse estudo caracteriza histologicamente a mucosa da câmara do espermacete de um espécime de K. sima e as glândulas relacionadas a sua produção secretória.(AU)

In this study we report the hematological, biochemical and hormonal parameters in a juvenile male Amazonian manatee measured before transport, immediately after transport, and during adaptation to a new facility. The animal was transported from Manaus, Amazonas State, Brazil, to São Paulo, São Paulo State, Brazil, (2,733 km) within 6 hours. Among all blood parameters analyzed, we observed obvious neutrophilia, lymphopenia, and increases in the neutrophil/lymphocyte ratio and serum glucose and aspartate aminotransferase (AST) levels, but these parameters subsequently returned to normal. These results suggest that transport and changes in the environment are temporary stressful events for Amazonian manatees. We, therefore, recommend monitoring the hematological and biochemical parameters before and after translocation to minimize the effects of handling stressors in this species.
Neste estudo, são relatados os parâmetros hematológicos, bioquímicos e hormonais em um peixe-boi da Amazônia macho jovem, medidos antes do transporte, imediatamente depois, e durante a sua adaptação a um novo recinto. O animal foi transportado de Manaus, Estado do Amazonas, Brasil, para São Paulo, Estado de São Paulo, Brasil, (2.733 km) durante 6h de viagem. Entre os parâmetros sanguíneos analisados, foi observada clara neutrofilia, linfopenia e aumento na relação neutrófilo/linfócito e nos níveis de glicose e aspartato aminotransferase (AST), mas estes parâmetros posteriormente voltaram aos valores normais. Estes resultados sugerem que o transporte e as mudanças no ambiente são eventos estressantes para o peixe-boi da Amazônia. Desta forma, é recomendável o monitoramento dos parâmetros hematológicos e bioquímicos antes e após a translocação para minimizar os efeitos de agentes estressores nesta espécie.

RESUMO
The most common penguin species found along the coast of Brazil is the Magellanic Penguin (Spheniscus magellanicus). These penguins spend most of their time foraging for food in the oceans. This information is vital to the maintenance of this species in captivity. The goal of this study was to evaluate the behavioral response of a group of Magellanic Penguins (S. magellanicus) in two different conditions of water--fresh and salt. The work was divided into two phases. First, animals were kept in enclosures with access to freshwater. Then they were housed with access to saltwater. Behaviors were recorded by scan sampling per interval of time, totaling 7,200 records for each animal. The results show that the use of saltwater for this group of animals kept in captivity was more effective for increasing the time the animals spent in the water, increasing foraging behavior, stimulating swimming, and providing display of typical behaviors of the species, showing that access to a saltwater environment is an important tool in trying to provide well-being for this species in captivity.

Captive penguins are prone to pododermatitis (bumblefoot) lesions due to sedentary habits, changes in normal activity patterns, prolonged time on hard and abrasive surfaces, and less time swimming in the water. Environmental enrichment allows the use of creative and ingenious techniques that aim to keep the captive animals occupied by increasing the range and the diversity of behavioral opportunities always respecting the ethological needs of the species. The main goal of this work was to use environmental enrichment techniques to reduce pododermatitis in a group of captive penguins. Five captive Magellanic penguins (Spheniscus magellanicus) that were showing bumblefoot lesions were followed during this project. To monitor the lesions, all animals were physically restraint 3 times a week over a period of 12 weeks. Environmental enrichment was introduced daily in the water with the goal of enhancing their time in the water for one extra hour daily. The results demonstrate that in a twelve weeks period, four animals showed significant reduction of the lesions in both feet and in two animals the lesions were completely healed. With these results we can conclude that aquatic environmental enrichment allowed this group of penguins to spend more time in the water, favoring the reduction of the bumblefoot lesions.
Os pinguins cativos estão predispostos a pododermatite (bumblefoot) devido ao sedentarismo, mudanças dos padrões normais de atividade, tempo prolongado de permanência em pisos duros e abrasivos, diminuição da natação e tempo na água. O enriquecimento ambiental permite a utilização de técnicas imaginativas e engenhosas que visam manter os animais cativos ocupados e com uma maior diversidade de oportunidades comportamentais, sempre respeitando as necessidades etológicas da espécie. O objetivo deste trabalho foi utilizar técnicas de enriquecimento ambiental para reduzir as lesões de pododermatite em um grupo de pingüins. Cinco indivíduos da espécie Pinguim-de-Magalhães (Spheniscus magellanicus) foram monitorados durante este projeto. Todos os animais foram contidos fisicamente 3 vezes por semana para a realização do acompanhamento do tamanho das lesões, durante 12 semanas. Enriquecimento ambiental foi introduzido diariamente na água, objetivando aumentar em uma hora o tempo em que os animais passavam na água. Os resultados mostraram que, ao longo das 12 semanas, 4 animais apresentaram redução significativa das lesões em ambas as patas, sendo que em dois animais as lesões desapareceram. Com isto, podemos concluir que o enriquecimento ambiental aquático para este grupo de pingüins permitiu um maior tempo de permanência dos animais na água favorecendo a redução das lesões de bumblefoot.

On October, 2009 and on May, 2011, two orphan lesser anteaters, with approximately two and five months of age, respectively, were received at the Aquário de São Paulo. Both were hand reared. Urine analysis were performed on both animals, and changes such as hematuria, pyuria and bacteria were observed. The treatment plan was chosen aiming to acidify the urine, eliminate the crystals and the bacterial infection. The antibiotics that were used were chosen according with the antibiograms" result. Preventive medicine programs are being performed frequently with the intention of establishing reference parameters of extreme relevance for the maintenance of this species in captivity. In the case of anteaters, who present low intrinsic rates of population growth, the maintenance of a minimum viable population is utterly necessary.
