Morbidity and Mortality of Birds of Prey Admitted to Rehabilitation Centers for Barbed Wire Injuries, New Mexico, USA, 2016-2021.

Interest in the role of fences in wildlife movement and injuries is growing, especially in the western US, where many miles of barbed wire fences crisscross the landscape. However, literature is limited on the effect of barbed wire on avian populations. From 2016 to 2021, six New Mexico, USA, rehabilitation centers accepted 49 raptors injured by barbed wire.

POSTRELEASE SURVIVAL OF CALIFORNIA BROWN PELICANS (PELECANUS OCCIDENTALIS CALIFORNICUS) FOLLOWING OILING AND REHABILITATION AFTER THE REFUGIO OIL SPILL.

Oil spills represent a continued threat to marine wildlife. Although the public expects, and the State of California, US requires, oiled animals to be rescued for rehabilitation and release, scientists have questioned the welfare and conservation value of capture and rehabilitation of oiled wildlife, based on poor postrelease survival documented in the few available studies. In May 2015, Plains Pipeline 901 spilled >100,000 gallons of oil near Refugio State Beach, California.

Giardia Infection and Trypanosoma Cruzi Exposure in Dogs in the Bosawás Biosphere Reserve, Nicaragua.

Indigenous Mayangna and Miskitu inhabit Nicaragua's remote Bosawás Biosphere Reserve, located in the North Caribbean Coast Autonomous Region. They are sedentary horticulturists who supplement their diet with wild game, hunting with the assistance of dogs. To test whether hunting dogs increased the risk of human exposure to protozoal zoonotic neglected tropical diseases (NTDs), we sampled dogs from three communities varying in population size and level of contact with other communities.

Rickettsia africae and Novel Rickettsial Strain in Amblyomma spp. Ticks, Nicaragua, 2013.

We report molecular detection of Rickettsia africae in Amblyomma ovale ticks from Nicaragua and a novel rickettsial strain in an A. triste tick. Of 146 ticks from dogs, 16.

Amphotericin B concentrations in healthy mallard ducks (Anas platyrhynchos) following a single intratracheal dose of liposomal amphotericin B using an atomizer.

Aspergillosis is a fungal infection that primarily affects the respiratory tract. Amphotericin B has broad antifungal activity and is commonly used to treat aspergillosis, a fungal pneumonia that is a common sequela in oiled waterfowl as well as other birds in wildlife rehabilitation. Pharmacokinetic parameters of nebulized amphotericin B in an avian model have been reported, but those of direct intratracheal delivery have yet to be established.

INTRAVENOUS REGIONAL ANTIBIOTIC PERFUSION THERAPY AS AN ADJUNCTIVE TREATMENT FOR DIGITAL LESIONS IN SEABIRDS.

Foot infections are a common problem among seabirds in wildlife rehabilitation. Pododermatitis and digital infections are often challenging to treat because of the presence of suboptimal substrates, abnormal weight-bearing due to injuries, and suboptimal nutritional or health status. Seabirds represent the majority of animals requiring rehabilitation after oil spills, and foot problems are a common reason for euthanasia among these birds.

Multiple-host pathogens in domestic hunting dogs in Nicaragua's Bosawás Biosphere Reserve.

Nicaragua's Bosawás Biosphere Reserve is a vast forested area inhabited largely by indigenous Mayangna and Miskitu people. Most Bosawás residents rely on subsistence hunting and swidden agriculture, and hunting dogs are important for finding and securing wild game. We investigated the health of hunting dogs in three communities differing in location, size, and economy.

Ophthalmic effects of petroleum dispersant exposure on common murres (Uria aalge): An experimental study.

The safety of chemical dispersants used during oil spill responses is largely unknown in birds. We captured common murres in Monterey Bay, CA and exposed them to Corexit EC9500a, crude oil, or a combination in artificial seawater. We performed ophthalmic examinations and measured intraocular pressures and tear production before and after exposure.

BEST-PRACTICE GUIDELINES FOR FIELD-BASED SURGERY AND ANESTHESIA ON FREE-RANGING WILDLIFE. II. SURGERY.

The principles of surgical asepsis apply to field surgeries with few exceptions. The minimum level for performance of surgeries in the field on free-ranging animals should be the same as for domestic animals undergoing surgery in animal hospitals. Surgeries in the field are typically done as part of research and management projects and usually involve a combination of biologists and veterinarians with the possibility of conflicts in scientific cultures.

BEST-PRACTICE GUIDELINES FOR FIELD-BASED SURGERY AND ANESTHESIA OF FREE-RANGING WILDLIFE. I. ANESTHESIA AND ANALGESIA.

Field anesthesia is often necessary for both invasive and noninvasive procedures on wild animals. We describe basic principles of safe anesthetic delivery, monitoring, and recovery for application in procedures involving free-ranging wildlife. For invasive procedures, the potential for immediate and lasting pain must be addressed and appropriate analgesia provided.

Comparison of anesthesia with fully reversible dexmedetomidine-butorphanol-midazolam versus ketamine-midazolam in captive Asian small-clawed otters (Aonyx cinereus).

Objective: To evaluate the efficacy and safety of a combination of dexmedetomidine, butorphanol, and midazolam administered IM for anesthesia in captive Asian small-clawed otters (Aonyx cinereus) and to compare this combination with a combination of ketamine and midazolam.

Design: Prospective crossover study.

Animals: 10 captive Asian small-clawed otters.

Evaluation of passive transfer in captive greater kudu (Tragelaphus strepsiceros).

Failure of passive transfer (FPT) in captive greater kudu (Tragelaphus strepsiceros) calves can lead to increased morbidity and mortality. In this retrospective study, serum samples from neonatal kudu calves were tested for immunoglobulin using different tests validated for domestic ruminants, including measurement of gamma globulin (GG) measured by protein electrophoresis, total solids (TS) measured by calibrated refractometry, total protein (TP) and globulins measured by colorimetry, gamma glutamyltransferase (GGT), and the zinc sulfate turbidity test (ZSTT). In a logistic regression model, TP, TS, globulins, and the natural log transform of GGT were the only significant parameters associated with FPT.

Hematology and absence of hemoparasites in breeding common terns (Sterna hirundo) from Cape Cod, Massachusetts.

In June and July 1995, 98 breeding common terns (Sterna hirundo) were captured, weighed, and bled as a part of ongoing research on the population health and reproductive biology of this species of special concern. Packed cell volume, total and differential white blood cell counts, and blood smears were obtained. Blood smears from 75 terns were examined.

Medical and surgical management of otitis in captive bongo (Tragelaphus eurycerus).

Six cases of severe otitis media-interna, an uncommon problem in nondomestic ruminants, were diagnosed in five captive bongo (Tragelaphus eurycerus). The cases were geographically clustered at zoological facilities in Florida. A visible ear droop, head shaking, and otic discharge were common at clinical presentation.

Health assessment of free-ranging three-banded (Tolypeutes matacus) and nine-banded (Dasypus novemcinctus) armadillos in the Gran Chaco, Bolivia.

The Gran Chaco, Bolivia, has a total of seven species of armadillos with the three-banded (Tolypeutes matacus) and nine-banded (Dasypus novemcinctus) the most commonly hunted by the local Isoseño-Guarani people. Armadillos are known carriers of zoonotic pathogens, including Mycobacterium leprae, Toxoplasma gondii, and Trypanosoma cruzi; thus human handling and consumption of these species may have a significant public health impact. A health assessment that included physical examinations, hematology, plasma biochemical analyses, levels of exposure to selected infectious agents, and endoparasite and ectoparasite identification was performed on nine-banded and three-banded armadillos in the Gran Chaco, Bolivia.

Antibiotic intravenous regional perfusion for successful resolution of distal limb infections: two cases.

Intravenous regional perfusion is a common technique for treating infections of the extremities in humans and horses. It has the advantage of achieving very high antibiotic concentrations in affected tissues. This technique was used to clinically resolve deep, mixed infections involving bones and joints in a swamp wallaby and a lesser kudu.

Surgical and medical management of a uterine spindle cell tumor in an African hedgehog (Atelerix albiventris).

A 5-yr-old female African hedgehog (Ateleris albiventris) presented with hematuria. Vulvar culture results revealed a 4+ growth of Enterococcus sp. and gamma-Streptococcus sp.

Serosurvey of small carnivores in the Bolivian Chaco.

Five species of Bolivian carnivores, including nine Geoffroy's cats (Oncifelis geoffroyi), ten ocelots (Leopardus pardalis), one jaguarundi (Herpailurus yaguarondi), nine pampas foxes (Pseudalopex gymnocercus), and five crab-eating foxes (Cerdocyon thous) were sampled between March 2001 and April 2005 and tested for antibodies to common pathogens of domestic carnivores. Carnivores were trapped in three areas: a village, the region between human settlements and a protected area, and within Kaa-Iya National Park, Bolivia. Antibodies to canine distemper virus were detected in ocelots and pampas foxes.

Diagnosis and treatment of presumptive postobstructive pulmonary edema in a Florida panther (Puma concolor coryi).

A free-ranging, adult male Florida panther (Puma concolor coryi) was immobilized and evaluated for hematuria following routine capture. Prior to anesthetic recovery, the panther was fitted with a telemetry collar. After an initially quiet recovery, the panther began thrashing in the transport cage, and was again immobilized.

Medical management of Toxoplasma meningitis in a white-throated capuchin (Cebus capucinus).

A 32-yr-old white-throated capuchin monkey (Cebus capucinus) was presented for paraparesis. A diagnosis of protozoal meningitis was made on the basis of a lymphocytic pleocytosis with elevated protein in cerebrospinal fluid and a positive serum titer to Toxoplasma gondii of 131,072 using an indirect hemagglutination test. Treatment with clindamycin and trimethaprim-sulfamethoxazole resulted in improvement within 3 days and complete clinical resolution within 2 wk.

Parasites of free-ranging small canids and felids in the Bolivian Chaco.

Parasite surveys of free-ranging wildlife provide important information for monitoring population health. Between March 2001 and March 2003, we sampled 10 ocelots (Leopardus pardalis), eight Geoffroy's cats (Oncifelis geoffroyi), a jaguarundi (Herpailurus yaguarondi), five pampas foxes (Pseudalopex gymnocercus), and three crab-eating foxes (Cerdocyon thous) at three sites in the Bolivian Chaco. The objective of the study was to survey the parasite fauna of these carnivores and compare prevalence of parasites among the sites.
