Baseline Gene Expression Levels in Falkland-Malvinas Island Penguins: Towards a New Monitoring Paradigm.

Health diagnostics of wildlife have historically relied on the evaluation of select serum biomarkers and the identification of a contaminant or pathogen burden within specific tissues as an indicator of a level of insult. However, these approaches fail to measure the physiological reaction of the individual to stressors, thus limiting the scope of interpretation. Gene-based health diagnostics provide an opportunity for an alternate, whole-system, or holistic assessment of health, not only in individuals or populations but potentially in ecosystems.

Case Studies of the Impacts of Cataract Surgery on Crested Penguin Welfare.

As nonhuman animals age, geriatric individuals require additional care and veterinary support to ensure their well being. The focus on lifelong care is a relatively newer approach when providing good welfare, and few studies have examined how veterinary care impacts behavior at different ages or how best to accommodate geriatric individuals in zoos. The objectives of this study were to (a) assess both the immediate and long-term (one year later) behavioral impacts of cataract removal for macaroni ( and southern rockhopper () penguins; (b) compare the behavior of penguins following cataract surgery to that of other conspecifics in the same habitat; and (c) monitor the impacts of cataract surgery on swimming behavior using time-depth recorders.

EVALUATION OF POTENTIAL RISK FACTORS ASSOCIATED WITH CATARACT IN CAPTIVE MACARONI (EUDYPTES CHRYSOLOPHUS) AND ROCKHOPPER PENGUINS (EUDYPTES CHRYSOCOME).

Complete ophthalmic examinations were performed on 160 Macaroni penguins ( Eudyptes chrysolophus ) and 90 Rockhopper penguins ( Eudyptes chrysocome ) at eight North American zoological institutions. Cataract prevalence in the Macaroni population was 46.5% (n = 74) of penguins and 42.

THE EFFECT OF UVB RADIATION ON SERUM VITAMIN D AND IONIZED CALCIUM IN THE AFRICAN SPOONBILL (PLATALEA ALBA).

Metabolic bone disease (MBD) was diagnosed in two chicks produced by a captive breeding colony of African spoonbills (Platalea alba). The birds were housed indoor during the winter breeding season and had no access to natural sunlight. When the index cases occurred, the nesting birds and chicks had a mean 25-hydroxyvitamin D (25-OHD) concentration of 9.

INTRAOCULAR PRESSURE IN SOUTHERN ROCKHOPPER (EUDYPTES CHRYSOCOME) AND MACARONI PENGUINS (EUDYPTES CHRYSOLOPHUS): EVALUATION OF INFLUENCING FACTORS.

Ophthalmic examinations were performed on 160 macaroni penguins (Eudyptes chrysolophus) and 90 southern rockhopper penguins (Eudyptes chrysocome) at eight North American zoos and aquaria. Intraocular pressure (IOP) was measured using rebound tonometry while penguins were held in two different body positions. Correlations between IOP and factors including age, body position, eye pathology, and housing parameters were evaluated.

The relationship between adult attachment style and post-traumatic stress symptoms: A meta-analysis.

There is increasing evidence that adult attachment plays a role in the development and perseverance of symptoms of posttraumatic stress disorder (PTSD). This meta-analysis aims to synthesise this evidence and investigate the relationship between adult attachment styles and PTSD symptoms. A random-effects model was used to analyse 46 studies (N=9268) across a wide range of traumas.

Diagnosis of Retrobulbar Round Cell Neoplasia in a Macaroni Penguin ( Eudyptes chrysolophus ) Through Use of Computed Tomography.

A 25-year-old female macaroni penguin (Eudyptes chrysolophus) was diagnosed with exophthalmos secondary to retrobulbar neoplasia through use of computed tomography (CT). Histopathologic examination of the mass supported a diagnosis of malignant round cell neoplasia. Immunohistochemical (IHC) labeling was applied to determine cell origin; the neoplastic cells did not label with T-cell marker CD3 or B-cell marker BLA.

Disseminated Mycobacterium haemophilum infection in an ASSAM trinket snake (Elaphe frenata).

A sub-adult male Assam trinket snake (Elaphe frenata) that was confiscated from an exotic animal dealer was found dead in its enclosure after a 17-mo quarantine. The snake had grown well during that period and had no physical examination or bloodwork abnormalities during the quarantine. On gross necropsy, masses were found in the epaxial musculature and stomach, the lung was diffusely thickened, the ventricular wall was mottled, and there was intracoelomic and pericardial effusion.

Operating theatre time, where does it all go? A prospective observational study.

Objective: To assess the accuracy of surgeons and anaesthetists in predicting the time it will take them to complete an operation or procedure and therefore explain some of the difficulties encountered in operating theatre scheduling.

Design: Single centre, prospective observational study.

Setting: Plastic, orthopaedic, and general surgical operating theatres at a level 1 trauma centre serving a population of about 370,000.

Ocular findings and reference values for selected ophthalmic diagnostic tests in the macaroni penguin (Eudyptes chrysolophus) and southern rockhopper penguin (Eudyptes chrysocome).

Objective: To describe ophthalmic examination findings and standard diagnostic test results in 2 penguin species.

Animals Studied: Macaroni & Southern Rockhopper Penguins.

Procedure: Complete ophthalmic examinations including Schirmer tear test (STT), modified phenol red thread test (PTT), tonometry, and echobiometry were performed on penguins housed at the Detroit Zoo.

Health sequelae of human cryptosporidiosis in immunocompetent patients.

Background: There have been no systematic studies following up the longer term health effects of cases of cryptosporidiosis for which genotype data exist.

Methods: We report a follow-up study of cases of laboratory-confirmed cryptosporidiosis. Case patients were sent a postal questionnaire asking about a wide range of symptoms occurring within 2 months after their initial diagnosis, and control subjects were sent the questionnaire 2 months after they had been recruited to the original study.

Sporadic cryptosporidiosis case-control study with genotyping.

We report a case-control study of sporadic cryptosporidiosis with genotyping of isolates from case-patients. A postal questionnaire was completed by 427 patients and 427 controls. We obtained genotyping data on isolates from 191 patients; 115 were Cryptosporidium hominis, and 76 were C.

Using a Geographical Information System to investigate the relationship between reported cryptosporidiosis and water supply.

BACKGROUND: This paper reports on a study investigating the epidemiology of sporadic cryptosporidiosis in the North West of England and Wales using a Geographical Information System (GIS) to map location of residence of cases. Some 747 reports of cases were made to CDSC North West of which 649 reports were suitable for analysis. Cases were plotted on the maps of water supply zone and water quality area boundaries, provided by the two main water utilities.

Foot and mouth disease and cryptosporidiosis: possible interaction between two emerging infectious diseases.

During 2001, a large outbreak of foot and mouth disease occurred in the United Kingdom, during which approximately 2,030 confirmed cases of the disease were reported, >6 million animals were slaughtered, and strict restrictions on access to the countryside were imposed. We report a dramatic decline in the reported incidence of human cryptosporidiosis in northwest England during weeks 13-38 in 2001, compared with the previous 11 years. This decline coincided with the period of foot and mouth restrictions.
