Patient Pleasure Pursuing Major Overall Leg Arthroplasty: Contributing Factors.
Zoos harbor large collections of diverse species, aiding in both conservation and education, as well as research in multiple scientific fields. However, the most common causes of death in zoo animals around the world remain unclear because few extensive reports or reviews are published on this topic. This information could greatly improve preventive veterinary medicine in zoologic gardens. This study provides a retrospective overview of the causes of death of animals from the Ljubljana Zoo in the years 2005-2015. During this period, a total of 353 animals were submitted for necropsy, of which 244 were mammals, 85 were birds, and 25 were reptiles. The causes of deaths were divided into infectious diseases (38%), dysfunctions of individual organs (20%), traumas (13%), parasitosis (7%), reproductive disorders (6%), metabolic disorders (3%), neoplastic disease (4%), and intoxications (4%). In some cases, the cause of death was unable to be determined (7%), most commonly because of autolysis of the body. The results of this retrospective study bring a general overview of the epizootiologic situation in the Ljubljana Zoo over an 11-yr period and valuable information to other zoos to optimize preventative plans and diagnostics.There are no published plasma biochemistry reference intervals for any species within the order Gaviiformes, which includes the common loon (Gavia immer). Because of their unique classification and lack of close taxonomic relatives, species-specific values for clinical data in loons are needed. This study determined reference intervals for plasma biochemical values in adult common loons, and reference intervals for protein electrophoresis values in both adult and juvenile common loons. Healthy, wild adult (n = 148, age >3 yr) and juvenile (n = 31, age 4-12 wk) common loons were sampled on freshwater summer breeding territories at study sites across North America. Plasma biochemical analytes included glucose (Glu), total calcium, phosphorus, sodium, potassium, chloride, blood urea nitrogen (BUN), uric acid, cholesterol, triglycerides, creatine kinase, γ-glutamyl transferase, alkaline phosphatase (ALP), lactate dehydrogenase, aspartate aminotransferase, amylase, and bile acids. Protein electrophoresis data included albumin to globulin ratio (A G), prealbumin, albumin, α1-globulin, α2-globulin, β-globulin, and γ-globulin. Adult females had significantly higher Glu, ALP, and BUN than adult males. Juvenile loons had higher β-globulins than adults, whereas adults had higher α1-globulins. Establishment of complete reference intervals will improve clinical assessment of captive loons, and allow researchers to better understand the health of wild loons in response to the multiple environmental stressors faced by these species.Improvements in husbandry, veterinary care, and nutrition have led to increased longevity of animals in human care, including elephants. The goal of this study was to collect and synthesize information pertaining to geriatric elephant medicine, management, husbandry, and nutrition. An electronic survey was created and distributed to American Association of Zoo Veterinarians members through an online link. A total of 61 responses were received from veterinarians, nutritionists, and elephant managers with data encompassing 314 elephants, of which 142 were geriatric (over 40 years old) and 51 were on their final set of molars. Following the initial survey, willing respondents were contacted for follow-up interviews. Osteoarthritis, foot disease, and colic were the most commonly reported diseases, and flunixin meglumine and phenylbutazone were the analgesics most often used. Respondents described diseases treated, husbandry changes specific for older animals, welfare assessments and quality of life monitoring, nutritional modifications for dental attrition, a variety of integrative medicine modalities, and unique cases. It is the hope that the information identified in this study can be used to improve treatment, management practices, and overall welfare for geriatric elephants.Improperly managed care conditions for reptiles can lead to clinical problems, including those of nutritional origin. A diagnostic tool to aid in the assessment of hepatic lipidosis is warranted. Evaluation of attenuation using quantitative computed tomography has a variety of indications in animals and permits the standardization of hepatic computed tomography (CT) reference values, aiding in the diagnosis of lipidosis. The objective of this paper was to estimate hepatic quantitative CT reference values for boas because of the lack of data in the literature for this species. CT scans were performed in 13 boas (Boa constrictor constrictor) 5 under managed care and 8 that were free ranging. Results show that the mean hepatic attenuation in the captive boa group was well below the mean for the free-ranging animals (P less then 0.05) with respective values of 48.78 ± 6.57 and 61.76 ± 7.11 HU. These results suggest an influence of managed care on liver attenuation. These results were observed despite the lack of clinical or laboratory changes. This imaging technique is useful to detect early hepatic changes; however, clinical relevance is unknown at this point. Further studies and standardization of species-specific values for hepatic quantitative CT would contribute to better understanding of the physiologic, physiopathologic, environmental, and nutritional processes.Infection with Yersinia pseudotuberculosis can be difficult to diagnose and treat successfully. Twenty-four cases from the Zoological Society of London (ZSL) London Zoo and ZSL Whipsnade Zoo were identified between 2001 and 2019. Husbandry, medical, and postmortem records for six primates, 10 artiodactyls, and eight birds were reviewed to identify common clinical signs and gross lesions. Most cases occurred during the winter; however, an outbreak in four primates occurred during the summer following a period of stress associated with increased ambient noise and activity. Common clinical signs included lethargy (6/6 primates, 4/10 artiodactyls, 4/8 birds) or death without premonitory signs (3/10 artiodactyls, 4/8 birds). see more Once clinical signs were observed, disease progressed quickly. Poor condition was common in mammals (6/6 primates, 9/10 artiodactyls), but often went undetected until postmortem examination. Neurological signs occurred in three of six primates. Diarrhea and anorexia were uncommon in all animals.
