Topical naltrexone potentiates cutaneous wound healing in blackbelt cichlids (Vieja maculicauda).

Objective: To evaluate the effects of topical naltrexone on wound healing in freshwater fish.

Animals: 25 blackbelt cichlids (Vieja maculicauda).

Methods: A randomized, controlled, experimental trial was performed, with each individual serving as its own control.

THE MANAGEMENT OF LYMPHOPROLIFERATIVE NEOPLASIA IN FOUR NORTHERN SEA OTTERS ().

Lymphoproliferative neoplasia has been reported in both free-ranging sea otters and those in managed care, but little information is available on the management of this neoplastic disease in this species. This case series describes clinical lymphoma in four northern sea otters () in managed care. Two otters presented with Stage 5 lymphoma with evidence of hematologic spread resulting in leukemia.

Otariid gammaherpesvirus 1 in South American fur seals (Arctocephalus australis) and a novel related herpesvirus in free-ranging South American sea lions (Otaria byronia): Prevalence and effects of age, sex, and sample type.

Otariid gammaherpesvirus 1 (OtGHV1) is associated with high rates of urogenital carcinoma in free-ranging California sea lions (Zalophus californianus; CSL), and until recently was reported only in the Northern Hemisphere. The objective of this study was to survey free-ranging South American sea lions (Otaria byronia; SASL) and South American fur seals (Arctocephalus australis: SAFS) in Punta San Juan, Peru for OtGHV1 and to determine prevalence characteristics. Twenty-one percent (14/67) of urogenital swabs collected over three years (2011, 2014, 2015) from live pinnipeds of both species tested positive with a pan-herpesvirus conventional PCR.

NALTREXONE AS A PROMISING TREATMENT FOR CLINICAL SIGNS OF LATERAL LINE DEPIGMENTATION IN PALETTE SURGEONFISH ().

Lateral line depigmentation (LLD) is a common condition in managed tropical saltwater fish, and treatment is somewhat elusive. Naltrexone, an opioid receptor antagonist, enhances epithelial cell replication, cytokine production, and angiogenesis to stimulate wound healing in mice. A treatment trial with 11 palette surgeonfish with LLD was performed.

Bioencapsulation is a feasible method of terbinafine administration in Emydomyces testavorans-infected western pond turtles (Actinemys marmorata).

Objective: To evaluate the pharmacokinetics of terbinafine administered to western pond turtles (Actinemys marmorata) via oral gavage and bioencapsulated in earthworms.

Animals: 7 western pond turtles.

Procedures: A randomized complete crossover single-dose pharmacokinetic study was performed.

ECHOCARDIOGRAPHIC PARAMETERS IN AFRICAN WHITE-BELLIED PANGOLINS () WITHOUT CARDIAC DISEASE.

Relatively little is known about pangolin care and physiology, and it has become increasingly important to have a better understanding of normal health parameters for evaluation of free-ranging, rehabilitating, and managed populations. Echocardiograms were performed on six African white-bellied pangolins () under professional care at a single institution. Because of the propensity of pangolins to roll up with only thick keratinized scales exposed, the pangolins were anesthetized with either isoflurane or sevoflurane.

SAFETY AND EFFICACY OF MILBEMYCIN OXIME AND LUFENURON TO TREAT SPP. INFESTATION IN SMOOTH BACK RIVER STINGRAYS () AND MAGDALENA RIVER STINGRAYS ().

Fish lice, ectoparasites of the genus , are branchurian crustaceans that can significantly impact fish health by causing mechanical damage to cutaneous barriers and increasing susceptibility to other infections. While many treatments have been reported in teleosts and invertebrates, there are no published treatments for elasmobranchs. This study evaluated the safety and efficacy of a commercial formulation of milbemycin oxime and lufenuron in freshwater stingrays for treatment of spp.

REPEATED ANESTHESIA IN A BLACK RHINOCEROS ( DICEROS BICORNIS) TO MANAGE UPPER RESPIRATORY OBSTRUCTION.

This report describes weekly repeated anesthesia in a 7-yr-old, 1,030 kg, female Eastern black rhinoceros ( Diceros bicornis michaeli), that was immobilized six times using a combination of 2 mg etorphine (0.002 mg/kg), 5 mg medetomidine (0.005 mg/kg), 25 mg midazolam (0.

SERUM COBALAMIN AND FOLATE CONCENTRATIONS AS INDICATORS OF GASTROINTESTINAL DISEASE IN KILLER WHALES ( ORCINUS ORCA).

Cobalamin and folate are water-soluble vitamins that are useful indicators of chronic gastrointestinal (GI) function in humans and some animal species. Serum cobalamin and folate concentrations in an ex situ population of killer whales ( Orcinus orca) were measured and factors that may affect their serum concentrations were identified. Serum samples ( n = 104) were analyzed from killer whales ( n = 10) both while clinically healthy and during periods of clinical GI disease as defined by clinical signs and fecal cytology.

PAROTID CARCINOMA IN A FREE-RANGING CALIFORNIA SEA LION ( ZALOPHUS CALIFORNIANUS).

A free-ranging juvenile California sea lion ( Zalophus californianus) stranded on the coast of Vancouver, British Columbia, with signs of lethargy and emaciation in April 2016. An asymmetrical skull with a prominent superficial cervical lymph node was found on initial assessment. Fine-needle aspirates and biopsies of the lymph node were consistent with neoplasia and the animal was humanely euthanized and presented for necropsy.

A test of the social cohesion hypothesis: interactive female marmots remain at home.

Individuals frequently leave home before reaching reproductive age, but the proximate causes of natal dispersal remain relatively unknown. The social cohesion hypothesis predicts that individuals who engage in more (affiliative) interactions are less likely to disperse. Despite the intuitive nature of this hypothesis, support is both limited and equivocal.
