Wild animals in Zoos across the globe are kept for aesthetic, educational, recreational and conservation purposes. Collections of rare and endangered species are also preserved in Zoos. Lions do well in captivity but are prone to excessive worm burden especially round worms and tapeworms though these conditions can easily be managed with adequate Veterinary services. Incidence of toxocariasis in captive African lions (Panthera leo) in Nigeria has largely not been reported. Jos Zoo and Wildlife Park both in Plateau State of Nigeria have lost significant number of lions to toxocariasis due to inadequate Veterinary attention A fatal case of toxocariasis in an African Lioness in Jos Zoological Garden, Nigeria was presented as a case study.

Hamsters have long been considered agricultural pests and their abundance has been controlled. Now in many countries they are recognized as rare and endangered species that are at a risk of extinction. Among conservation measures to preserve and restore the population of many species is to gain experience in their keeping and reproduction in captivity. The experiments were carried out with hamsters obtained from the Crimea at different times. The keeping experience of hamsters in an ordinary residential apartment and the specifics of domestication of the animals caught in the nature are described. Their captivity, cage arrangement, nutrition, reproduction, specifics of communication, seasonal and circadian rhythms, territorial behaviour, threats and factors influencing their well-being are described in detail. Practice has shown that these are friendly and interacting animals to keep at home, and their breeding as pets is promising. Even adults caught in a trap get used to people in 2–4 weeks, take food from hands, go to the cage door when they are called, remember their nickname, calmly walk on the hands and do not bite at all, even when their babies are taken to the hands. Although hamsters are nocturnal in the nature, they are often active during the day at home. They do not hibernate and are active all-year-round, and even breed in winter. Hamsters are highly sensitive to overheating and draft; both are harmful to them and lead to death. In the evenings, while walking around the room hamsters do not run away and do not hide; the cage is considered their territory, safe, and cosy. Therefore, after walks, they go to the cages themselves or ask to be placed in the cage. Quickly master the treadmill and run in it for hours. Hamsters are very different by their individual behaviour and preferences. The purpose of keeping hamsters in captivity is to introduce the species as pets and to form so-called ‘reserve populations’ to restore populations of the species in the wild. Being among the pets, this species will be preserved in the culture and will be able to be released in places where their existence would be desirable. Based on the experience gained from keeping hamsters in captivity, steps to form "wild" behaviour are recommended. The formation of artificial breeding groups, which together form a reserve population, is an important measure in restoration programmes of natural populations of Cricetus cricetus.

Post Mortem Findings

Background The zoo is a unique environment in which to study animals. Zoos have a long history of research into aspects of animal biology, even if this was not the primary purpose for which they were established. The data collected from zoo animals can have a great biological relevance and it can tell us more about what these animals are like outside the captive environment. In order to ensure the health of all captive animals, it is important to perform a post-mortem examination on all the animals that die in captivity. Methods The causes of mortality of two hundred and eighty two mammals which died between 2004 and 2015 in three different Italian zoos (a Biopark, a Safari Park and a private conservation center) have been investigated. Results Post mortem findings have been evaluated reporting the cause of death, zoo type, year and animal category. The animals frequently died from infectious diseases, in particular the causes of death in ruminants were mostly related to gastro-intestinal pathologies. pulmonary diseases were also very common in each of the zoos in the study. Moreover, death was sometimes attributable to traumas, as a result of fighting between conspecifics or during mating. Cases of genetic diseases and malformations have also been registered. Discussion This research was a confirmation of how conservation, histology and pathology are all connected through individual animals. These areas of expertise are extremely important to ensure the survival of rare and endangered species and to learn more about their morphological and physiological conditions. They are also useful to control pathologies, parasites and illnesses that can have a great impact on the species in captivity. Finally, this study underlines the importance of a close collaboration between veterinarians, zoo biologists and pathologists. Necropsy findings can help conservationists to determine how to support wild animal populations.

Tumor Like Lesions

ABSTRACT: Avipoxvirus is the etiological agent of the avian pox, a well-known disease of captive and wild birds, and it has been associated with tumor-like lesions in some avian species. A white-faced whistling duck (Dendrocygna viduata) raised in captivity was referred to a Veterinary Teaching Hospital in Northeast due to cutaneous nodules present in both wings. A few days after the clinical examination, the animal died naturally. Once submitted to necropsy, histopathological evaluation of the lesions revealed clusters of proliferating epithelial cells expanding toward the dermis. Some of these cells had round, well-defined, intracytoplasmic eosinophilic material suggestive of poxvirus inclusion (Bollinger bodies). PCR performed on the DNA extracted from tissue samples amplified a fragment of the 4b core protein gene (fpv167), which was purified and sequenced. This fragment of Avipoxvirus DNA present in these tumor-like lesions showed high genetic homology (100.0%) with other poxviruses detected in different avian species in several countries, but none of them were related to tumor-like lesions or squamous cell carcinoma. This is the first report of Avipoxvirus detected in tumor-like lesions of a white-faced whistling duck with phylogenetic analysis of the virus.

In modern biology, a search for efficient and safe ways of long-term storage of animal genomes is vital for the survival of rare and endangered species. To date, the only reliable method of prolonging the preservation of genome is deep freezing of somatic and reproductive cells, including spermatozoa. Here we overview the current state of reproductive technologies and present the cryopresevation strategies of genetic material of selected amphibian species. These strategies were developed at the Institute of Cell Biophysics, Russian Academy of Sciences, Pushchino, Russia. Cryopreservation could help managing the threatened populations of amphibian species through genome storage and mediate the production of healthy animals from the stored material.

The five new steppe-meadow associations are des­cribed in the South Urals. They refer to the class Molinio-Arrhenatheretea R. Tx. 1937 em. R. Tx. 1970, ord. Galietalia veri Mirkin et Naumova 1986, all. Trifolion montani Naumova 1986, and the suball. Trifolienion montani Mirkin et Naumova 1986. The communities of these associations are typical of their richness in species, including such rare and endangered ones as Dianthus acicularis, Stipa korshinskyi, Stipa sareptana, Stipa zalesski, Stipa pennata, Stipa da­syphylla, Tulipa biebersteiniana etc., the fact which makes for their significant value for nature protection purposes.
