Xenotransplantation of porcine progenitor cells in an epileptic California sea lion (Zalophus californianus): illustrative case.

Background: Domoic acid (DA) is a naturally occurring neurotoxin harmful to marine animals and humans. California sea lions exposed to DA in prey during algal blooms along the Pacific coast exhibit significant neurological symptoms, including epilepsy with hippocampal atrophy.

Observations: Here the authors describe a xenotransplantation procedure to deliver interneuron progenitor cells into the damaged hippocampus of an epileptic sea lion with suspected DA toxicosis.

Population Pharmacokinetics of Danofloxacin After Single Intramuscular Dose Administration in California Brown Pelicans ().

The pharmacokinetics of danofloxacin was investigated in rehabilitated California brown pelicans () after a single intramuscular injection at a dose of 15 mg/kg body weight. The concentration of the drug in plasma was assayed by high-pressure liquid chromatography. A sparse-sampling design was used to reduce the number of samples (1-4 venipunctures) obtained from 24 brown pelicans.

Severe Sea Lion Bites in Urban Cold-Water Swimmers.

Background: A series of sea lion bites in open-water swimmers recently gained the attention of the national and international media. Pinniped (the clade including seals and sea lions) bites historically have been in people who hunt or handle marine mammals. As populations of humans and pinnipeds continue to grow, interactions with animals by those participating in recreational activities are likely to become more frequent.

Cetacean Morbillivirus in Odontocetes Stranded along the Central California Coast, USA, 2000-15.

Effects of cetacean morbillivirus (CeMV) on dolphins vary from causing epidemics to subclinical infections. The former have been documented in the North Atlantic Ocean and Mediterranean Sea but not in the North Pacific Ocean, and the reasons for this are unknown. To explore the distribution of this virus in areas that have not experienced epidemics, we reviewed evidence for morbilliviral infection in odontocetes stranded along the California coast, US from 2000-15.

Clinical management of Candida albicans keratomycosis in a bottlenose dolphin (Tursiops truncatus).

Objective: Corneal ulceration secondary to trauma commonly affects marine mammals, often with opportunistic secondary bacterial or fungal infections. This report characterizes the combined use of auriculopalpebral and ophthalmic nerve blocks, adipose-derived stem cells, and subconjunctival injections for successful treatment of corneal trauma and infection in dolphins.

Animal Studied: An 11-year-old, female bottlenose dolphin (Tursiops truncatus) presented with bilateral diffuse corneal opacities, which progressed to keratomycosis caused by Candida albicans.

Subconjunctival antimicrobial poloxamer gel for treatment of corneal ulceration in stranded California sea lions (Zalophus californianus).

Objective: Corneal ulcers are commonly encountered in pinnipeds. Prolonged oral antibiotics and topical ophthalmic solutions may not be practical to administer, and novel treatment techniques are desired. Thermodynamic gels are a potential solution because they hold antimicrobials at the site of injection, slowly releasing drug.

Implementing HIV Testing in Substance Use Treatment Programs: A Systematic Review.

People who use drugs are at increased risk for HIV acquisition, poor engagement in health care, and late screening for HIV with advanced HIV at diagnosis and increased HIV-related morbidity, mortality, and health care costs. This systematic review evaluates current evidence about the effectiveness and feasibility of implementing HIV testing in U.S.

A Systematic Review of Changes in Marine Mammal Health in North America, 1972-2012: The Need for a Novel Integrated Approach.

Marine mammals are often cited as "sentinels of ocean health" yet accessible, synthesized data on their health changes that could effectively warn of ocean health changes are rare. The objectives of this study were to 1) perform a systematic review of published cases of marine mammal disease to determine spatial and temporal trends in disease from 1972-2012, including changes in regions and taxa affected and specific causes; and 2) compare numbers of published cases of neoplasia with known, hospital-based neoplasia records to explore the causes of discrepancy between numbers of published cases and true disease trends. Peer-reviewed literature was compiled, and data were collected from The Marine Mammal Center database in Sausalito, California for comparison of numbers of neoplasia cases.

California Sea Lion (Zalophus californianus) and Harbor Seal (Phoca vitulina richardii) Bites and Contact Abrasions in Open-Water Swimmers: A Series of 11 Cases.

Objective: To review cases of bites and contact abrasions in open-water swimmers from California sea lions (Zalophus californianus) and harbor seals (Phoca vitulina richardii).

Methods: Open-water swimmers from a San Francisco swimming club were questioned about encounters with pinnipeds (seals and sea lions) that resulted in bites or contact abrasions. When possible, wounds were documented with photographs.

APHAKIC PHACOEMULSIFICATION AND AUTOMATED ANTERIOR VITRECTOMY, AND POSTRETURN MONITORING OF A REHABILITATED HARBOR SEAL (PHOCA VITULINA RICHARDSI) PUP.

A female harbor seal pup rescued along the coast of San Diego on 13 June 2012 was diagnosed with bilateral mature cataracts, apparently congenital, in association with vitreal herniation in the anterior chamber of each eye. The cataracts were surgically removed on 1 August 2012 with single-port aphakic phacoemulsification and automated anterior vitrectomy. Postoperative monitoring during the next several weeks indicated that vision had been functionally repaired and that she could visually orient to and capture live fish in three different environments and in the presence of other animals.

CHARACTERIZATION OF A FOLLICULAR CELL CARCINOMA OF THE THYROID IN A YELLOWBAR ANGELFISH (POMACANTHUS MACULOSUS).

Histopathologic diagnosis of thyroid neoplasia in teleosts is complicated, because thyroid tissue is unencapsulated, and normal tissue can have wide ectopic extensions. Assessment of thyroid hormone concentrations in conjunction with histologic evaluation of thyroid carcinoma has not been reported in teleosts, even though routinely performed in other species. A yellowbar angelfish (Pomacanthus maculosus) presented with a mass that extended beyond the gill arches.

Pharmacokinetics of single dose oral meloxicam in bottlenose dolphins (Tursiops truncatus).

The objective of this study was to investigate the pharmacokinetics of meloxicam in bottlenose dolphins (Tursiops truncatus). Ten adult bottlenose dolphins were used for the study. Each animal received a single oral dose of meloxicam at 0.
