ABSTRACT: Primary gallbladder neoplasms occur infrequently in domestic animals and rarely in wild animals. This article describes a case of gallbladder adenoma in a mongoose ( Mungos mungo) in captivity. Grossly, the gallbladder was moderately distended with a smooth capsular surface. Necropsy showed an irregular, soft, whitish nodule 0.8cm in diameter. Microscopic examination of the nodule showed proliferation of epithelial cells, which projected from the mucosa and formed papillary projections supported by a sparse fibrovascular stroma. Neoplastic cells were well differentiated with mild anisocytosis and anisokaryosis. Based on these histopathological findings, adenoma of the gallbladder was diagnosed.

ABSTRACT: Bovine tuberculosis (bTB) is an infectious disease caused by Mycobacterium bovis, affecting domestic animals, wild animals and humans. In captivity, for wild animals, bTB represents a risk to animal keepers and zoo visitors, in addition to the possibility of spreading the infection to domestic animals or through the trade of infected wild animals. Sambar (Cervus unicolor), red deer (Cervus elaphus) and fallow deer (Dama dama) from a safari park in the State of Rio Grande do Sul, Brazil, showed a clinical condition of dyspnea and weight loss. Some animals died and showed lesions suggestive of tuberculosis (LST), which were confirmed by histopathology. After the interdiction of the safari park by the state veterinary authorities, 281 deer were euthanized with the authorization of the “Instituto Brasileiro do Meio Ambiente e dos Recursos Naturais Renováveis” (IBAMA). Retropharyngeal and submandibular lymph nodes and viscera were collected from 21 animals, which were grown in Stonebrink medium for up to 90 days. After DNA extraction from the bacterial colonies, PCR was performed for targets flanking the region of differentiation 4 (RD4). Of the 21 samples, 14 (66.7%) presented LST with a granulomatous appearance, a whitish coloration, and caseous or calcified consistency, and seven samples (33.3%), showed no lesions. In the culture of 14 samples with LST, 13 (92.8%) presented bacterial growth compatible with M. bovis. In the cultivation of the seven samples without LST, four (57.1%) presented colonies compatible with M. bovis. PCR and DNA sequencing of the PCR amplicons detected as positive all the 17 (100%) bacteriological cultures suggestive of M. bovis, thus confirming the outbreak of bTB in deer. Decisions about positive tested and suspicious animals should be taken based on the evaluation of the risk of transmission to the rest of the zoological animals, animal welfare, conservation considerations and, the zoonotic potential of this pathogen.

Plexus Papilloma

Choroid plexus tumors (CPT) are rare neoplasms and histologically classified as choroid plexus papilloma (CPP), atypical choroid plexus papilloma (APP), and choroid plexus carcinoma (CPC). These neoplasms have been described in humans, domestic animals (canine, feline, equine, caprine) and some wild animals (cetaceans and Psittacidae birds). To our best knowledge, herein we report the first CCP in a free-ranging eared dove (Columbiformes; Zenaida auriculata, de Murs 1847). Histologically, the ventricle was dilated, with a papillary proliferation (arboriform pattern) in topography of CP. The neoplasm was well-differentiated, composed by a single layer of cuboidal cells, anchored in a delicate fibrovascular stroma. The neoplastic cells exhibited moderate stroma, with well-defined borders and round nuclei, with vesicular chromatin and inconspicuous nucleoli. Mitotic activity was low (<1 mitosis per 10 high-power fields). Immunohistochemistry for cytokeratin markers (AE1/AE3 antibody) were implemented, however, both neoplastic cells and normal epithelial tissues do not show immunoreactivity.

Captive breeding programmes are increasingly relied upon for threatened species management. Changes in morphology can occur in captivity, often with unknown consequences for reintroductions. Few studies have examined the morphological changes that occur in captive animals compared with wild animals. Further, the effect of multiple generations being maintained in captivity, and the potential effects of captivity on sexual dimorphism remain poorly understood. We compared external and internal morphology of captive and wild animals using house mouse ( Mus musculus ) as a model species. In addition, we looked at morphology across two captive generations, and compared morphology between sexes. We found no statistically significant differences in external morphology, but after one generation in captivity there was evidence for a shift in the internal morphology of captive-reared mice; captive-reared mice (two generations bred) had lighter combined kidney and spleen masses compared with wild-caught mice. Sexual dimorphism was maintained in captivity. Our findings demonstrate that captive breeding can alter internal morphology. Given that these morphological changes may impact organismal functioning and viability following release, further investigation is warranted. If the morphological change is shown to be maladaptive, these changes would have significant implications for captive-source populations that are used for reintroduction, including reduced survivorship.

Playback experiments have proved to be a useful tool to investigate the extent to which wild animals understand numerical concepts and the factors that play into their decisions to respond to different numbers of vocalizing conspecifics. In particular, playback experiments have broadened our understanding of the cognitive abilities of historically understudied species that are challenging to test in the traditional laboratory, such as members of the Order Carnivora. Additionally, playback experiments allow us to assess the importance of numerical information versus other ecologically important variables when animals are making adaptive decisions in their natural habitats. Here, we begin by reviewing what we know about quantity discrimination in carnivores from studies conducted in captivity. We then review a series of playback experiments conducted with wild social carnivores, including African lions, spotted hyenas and wolves, which demonstrate that these animals can assess the number of conspecifics calling and respond based on numerical advantage. We discuss how the wild studies complement those conducted in captivity and allow us to gain insights into why wild animals may not always respond based solely on differences in quantity. We then consider the key roles that individual discrimination and cross-modal recognition play in the ability of animals to assess the number of conspecifics vocalizing nearby. Finally, we explore new directions for future research in this area, highlighting in particular the need for further work on the cognitive basis of numerical assessment skills and experimental paradigms that can be effective in both captive and wild settings. This article is part of a discussion meeting issue ‘The origins of numerical abilities’.

Infectious diseases in wild animals have been increasing as a result of their habitat alterations and closer contact with domestic animals. Canine distemper virus (CDV) has been reported in several species of wild carnivores, presenting a threat to wildlife conservation. We described the first case of canine distemper virus infection in lesser grison (Galictis cuja). A free-ranging individual, with no visible clinical sigs, presented sudden death after one day in captivity. Molecular diagnosis for CDV infection was performed using whole blood collected by postmortem intracardiac puncture, which resulted positive. The virus phylogeny indicated that domestic dogs were the probable source of infection.

Animals were a permanent element in the landscape of medieval towns. Many residents of the then urban centres lived of animal husbandry. In addition to farm animals (e.g. pigs), they kept domestic animals (e.g. dogs and cats) as well as wild animals. The latter often sought food in garbage and suburbs. Such animals were also kept for entertainment. Authorities of Prussian towns regulated many issues related to the functioning of towns, including those concerning animal husbandry. Animals could pose a threat to the health and life of residents. They were also considered to be pests that destroy crops, orchards, and household appliances. The legislation of the period was focused on determining guilt for crimes and offenses committed by animals. Either an animal, treated as an entity responsible for the harmful act, or its owner was blamed for the misconducts. The presence of animals, especially livestock, was considered to be the cause of considerable sanitary problems in towns, mainly due to animal waste. Town authorities regulated issues concerning cattle herding and grazing. The care over the herd was entrusted to urban shepherds whose service was regulated by town legislation. The problem of the perception of animals by the society of that time was also significant. Although seemingly unwanted, they were the only source of income for many residents. For some, animals were pests, and for others, a guarantee of fragile existence. It was also a time when people began to wonder what exactly an animal is, what role it should play in human life, and how to treat it.

The deer park at Downley is one of many medieval parks known from the county of Sussex (UK), 8km north of Chichester. The park belonged to the Earls of Arundel and there is evidence of its occasional use by high-status figures, such as King Henry VIII. The park perimeter measures 6.6km and covers an area of 261.7ha. During the first season of excavation in 2014 the presence of a substantial lodge building was proven within the pale, the features associated with the lodge contained various archaeological and environmental remains. This paper focuses on the study of zooarchaeological materials recovered from the 16 trenches opened in 2014. All faunal remains were studied, revealing domestic animals such as cattle and sheep, as well as wild animals such as deer and boar. Fallow deer is the most frequent species showing a very complete body part representation, suggesting it was hunted and processed locally. Further work is carried out looking at body part representation, which is particularly important when looking at the ritualised dismemberment of hunted animals. In any hunting milieu dogs/hounds are prevalent, and are represented by some anatomical elements, but also by considerable evidence of gnawing marks on bones that were clearly humanly processed before being fed to the animals.
