Biosignature Molecules Accumulate and Persist in Evaporitic Brines: Implications for Planetary Exploration.

The abundance of potentially habitable hypersaline environments in our solar system compels us to understand the impacts of high-salt matrices and brine dynamics on biosignature detection efforts. We identified and quantified organic compounds in brines from South Bay Salt Works (SBSW), where evapoconcentration of ocean water enables exploration of the impact of NaCl- and MgCl-dominated brines on the detection of potential biosignature molecules. In SBSW, organic biosignature abundance and distribution are likely influenced by evapoconcentration, osmolyte accumulation, and preservation effects.

VALIDATION OF A NOVEL ENZYME-LINKED IMMUNOSORBENT ASSAY FOR DETECTING PREGNANCY-SPECIFIC PROTEIN B IN MASAI GIRAFFE ().

The Masai giraffe () is endangered in the wild, and successful reproduction in managed care is important to help maintain assurance populations of this highly charismatic subspecies. Detection of pregnancy in giraffes using hormonal monitoring requires multiple samples and cannot distinguish pregnancy from pseudopregnancy. A novel enzyme-linked immunosorbent assay that can detect pregnancy-specific protein B (PSPB) for pregnancy diagnosis with a single serum sample was developed from a reticulated giraffe () placenta.

USE OF HYSTEROSCOPIC MORCELLATION WITH A MYOSURE DEVICE FOR REMOVAL OF UTERINE FOREIGN MATERIAL IN AN ORANGUTAN ( SP.).

A 36-yr-old female intact hybrid orangutan ( sp.) presented with evidence of chronic bacterial cystitis with no response to treatment with multiple systemic antibiotics. Abnormalities were identified within the reproductive tract on CT scan, and hysteroscopy was pursued based on the recommendation of an obstetrician-gynecologist.

HEALTH ASSESSMENT OF PAINTED TURTLES (CHRYSEMYS PICTA) IN A RESTORED WETLAND HABITAT IN NORTHWESTERN INDIANA, USA.

Freshwater turtles are sensitive to environmental changes and can serve as sentinel species for ecosystem health assessments. The Efroymson Restoration at Kankakee Sands in northwestern Indiana, USA has been restored in the past 25 yr from primarily agricultural land to a mosaic of prairie and wetland habitats. Health assessments of 40 free-ranging painted turtles (Chrysemys picta) at Kankakee Sands were performed in May 2021 to evaluate overall health status, screen for infectious diseases, and obtain baseline clinical pathology values in this population.

EFFECT OF BODY POSITION ON ECHOCARDIOGRAPHIC PARAMETERS IN PRAIRIE RATTLESNAKES ().

Echocardiography is a noninvasive diagnostic tool that can provide instantaneous information about cardiac function, but it is uncommonly used by veterinarians to assess reptilian patients. Echocardiograms were performed on 14 clinically healthy, adult prairie rattlesnakes (), and cardiac measurements were taken in a horizontal and vertical position. Cardiac parameters including ventricular volume in systole and diastole, as well as the diameter of the left atrium, pulmonary artery, and paired left and right aortic arches were obtained.

A Outbreak in Fox Squirrels () and Subsequent Detection of in Kansas, USA.

Thorough epidemiologic investigations of wildlife mortality events are often challenging, in part because of the dynamic variables involved. In May 2011, six fox squirrels () in Clinton State Park, Kansas, US were euthanized after exhibiting clinical signs of neurologic disease. Postmortem examination of two squirrels revealed that these individuals died of larva migrans, which resulted in meningoencephalitis and variable pneumonia and myocarditis.

Comparison of field surveillance methods for and assessment of factors potentially associated with the presence of free-roaming cats in a mixed-urban environment.

OBJECTIVE To evaluate 2 methods of surveying free-roaming cats (Felis catus) and identify factors potentially associated with the presence of such cats in a mixed-urban environment. ANIMALS Free-roaming cats on and near The Ohio State University campus. PROCEDURES The university campus and surrounding areas were divided into zones classified by land-use category; 100 zones were selected for surveillance of free-roaming cats by the line-transect method (with visual observation).
