Elephant endotheliotropic herpesviruses (EEHVs) can cause fatal hemorrhagic disease in juvenile Asian elephants (Elephas maximus); however, sporadic shedding of virus trunk washes collected from healthy also has been detected. Data regarding the relationship viral loads blood compared with are lacking, and questions about whether undergo multiple infections EEHVs have not addressed previously. Real-time quantitative polymerase chain reaction was used to determine kinetics EEHV1 loads,...

Abstract Case Description —A female Aldabra tortoise ( Geochelone gigantea ) was evaluated because of focal necrosis the carapace. Clinical Findings —Debridement revealed a 14.5 × 11.5-cm area shell necrosis, deep abscess formation, and osteomyelitis involving bacterial Klebsiella pneumoniae , Staphylococcus aureus Pseudomonas spp) fungal pathogens. Treatment Outcome —Following extensive debridement, vacuum-assisted closure incorporating silver-impregnated bandaging materials used. The wound...

Following a first clinical case of infection by Diphyllobothrium dendriticum in Switzerland 2006, we report second the country. The species was identified molecular methods. In Swiss, French and Italian subalpine regions, human diphyllobothriasis has seen comeback since late 1980's, latum is usually considered causative agent disease. addition, several locally acquired imported infections due to allochthonous have been documented last years. Due colonisation potential these parasites their...

Five painted storks were treated with fenbendazole for 5 days internal parasitism. Four birds died following treatment. Profound heteropenia was a consistent finding in all samples evaluated; additionally, the 1 surviving bird had progressive anemia. Consistent necropsy findings 4 that small intestinal crypt cell necrosis and severe bone marrow depletion necrosis. Fenbendazole has been associated hypoplasia enteric damage mammals other species of birds. The dosages used are often...

Abstract Chemical deterioration of teeth is common among modern humans, and has been suggested for some extinct primates. Dental erosion caused by acidic foods may also obscure microwear signals mechanical food properties. Ring‐tailed lemurs at the Beza Mahafaly Special Reserve (BMSR), Madagascar, display frequent severe tooth wear subsequent loss. In contrast, sympatric Verreaux's sifaka far less infrequent loss, despite both species regularly consuming tamarind fruit. We investigated...

Six adult female tigers (Panthera tigris) were anesthetized repeatedly for elective medical procedures using 3 mg medetomidine and 200 ketamine i.m. Inductions rapid smooth, although supplemental was needed safe transport after induction in 6 of 17 procedures. Reversal the medetomidine-induced sedation with 15 atipamezole 59–232 min resulted recoveries.

A combination of low serum calcium (Ca), high phosphorus (P), and magnesium (Mg) has been observed in individual captive ruminants, primarily affecting kudu (Tragelaphus strepsiceros), eland (Taurotragus oryx), nyala angasii), bongo eurycerus), giraffe (Giraffa camelopardalis). These mineral abnormalities have associated with chronic laminitis, acute tetany, seizures, death. Underlying rumen disease secondary to feeding highly fermentable carbohydrates was suspected be contributing the...

We report three cases of sparganosis due to plerocercoids the tapeworm Spirometra sp. in captive meerkats (Suricata suricatta) from a zoo exhibit southeastern United States. Two were euthanized, one an uncontrollable seizure and other trauma, at necropsy cysts containing cestode larvae observed. A third meerkat had subcutaneous nodule surgically removed, which contained similar larvae. The animal died years later, numerous pleural peritoneal cavities. morphologically identified as...

Abstract Case Description —4 North American porcupines were evaluated because of diarrhea or neutropenia (or both) that developed after treatment with fenbendazole for intestinal parasites. Clinical Findings —Complete blood cell count abnormalities included severe in all affected and mild anemia some them. In 2 porcupines, postmortem findings bone marrow hypoplasia crypt necrosis. Treatment Outcome —Affected received supportive care including fluid supplementation broad-spectrum...

Standing sedation was provided for 14 clinical procedures in three African elephants (Loxodonta africana) managed by combined protected and modified-protected contact trained through operant conditioning. An initial hand-injection of detomidine hydrochloride butorphanol tartrate at a ratio 1:1 on microg:microg basis administered intramuscularly, with dosage range 50-70 mg (12.9-19.7 microg/kg) each drug. The injection resulted adequate initiation completion eight procedures, whereas...

Abstract Like most of Madagascar's endemic primates, ring‐tailed lemurs ( Lemur catta ) face a number threats to their survival. Although habitat loss is greatest concern, other anthropogenic factors including environmental contamination may also affect lemur health and In this study, we examined from the Beza Mahafaly Special Reserve (BMSR), southern Madagascar for exposure organochlorine (OC) pesticides metals differences in contaminant concentrations between sexes among age groups,...

Ten cotton-topped tamarins (Saguinus oedipus) were infected with Moniliformis clarki a parasitic acanthocephalan. One animal died of intestinal perforation and peritonitis before treatment was initiated. Five the remaining treated successfully oral albendazole at either 50 mg/kg b.i.d. for 16 days or 100 3 days, then repeated biweekly four treatments. A less-intensive regime orally s.i.d. monthly treatments unsuccessful. Parasites removed via surgical enterotomy from two animals, both which...

Elegant-crested tinamou (Eudromia elegans) are members of the family Tinamidae. A review postmortem records at Saint Louis Zoo suggests that this species is highly susceptible to aspergillosis. Antemortem detection Aspergillus infections can be aided by evaluating results hematologic, plasma biochemical, protein electrophoretic, and antigen antibody serologic testing. To establish species-specific reference intervals for these parameters in elegant-crested tinamou, blood samples were...

Intestinal strictures were diagnosed in two captive cheetahs (Acinonyx jubatus jubatus). The presented with lethargy, anorexia, diarrhea, and weight loss. first cheetah had a stricture of the ileocecocolic junction at necropsy. second an causing obstruction that was surgery. After resection anastomosis, recovered well. etiology remains undetermined. stricture, particularly junction, should be considered as differential diagnosis for nonspecific gastrointestinal signs.
