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 neutropenia in all affected porcupines and mild anemia in some of them. In 2 porcupines, postmortem findings included bone marrow hypoplasia and intestinal crypt cell necrosis.

Treatment and Outcome—Affected porcupines received supportive care including fluid supplementation and broad-spectrum antimicrobials. The 2 surviving animals recovered after 9 to 33 days of treatment.

Conclusions and Clinical Relevance—Fenbendazole is an anthelminthic that may be used in an extralabel manner for the treatment of intestinal parasitism in wildlife species. The drug inhibits mitosis and can affect rapidly dividing cell lines, such as those in the bone marrow and intestinal crypt mucosa. Fenbendazole may not be an appropriate anthelminthic choice in North American porcupines.

To design a diagnostic protocol that uses appropriate techniques, including ultrasonography, to assess cardiovascular health and detect primary cardiac diseases in gorillas and to establish a database of reference values for cardiac measurements in clinically normal gorillas.


Prospective study.


5 adult male lowland gorillas from 11 to 18 years old.


A complete cardiac evaluation was performed on anesthetized gorillas, including physical examination, thoracic radiography, electrocardiography, echocardiography, blood pressure determination, CBC, serum biochemical analyses, and serologic assay for viral diseases. Standard cardiac measurements were made from images collected during ultrasonography.


Cardiac measurements derived from ultrasonographic images were consistent with those considered normal in human beings. Results of other diagnostic tests were also considered normal.

Clinical Implications

Cardiac disease is the primary cause of mortality in old captive gorillas. The technique used here provided excellent evaluation of cardiac function. Use of these techniques will allow early detection of cardiac disease, making treatment or medical management possible. (J Am Vet Med Assoc 1998; 212:413-415)

Case Description—A female Aldabra tortoise (Geochelone gigantea) was evaluated because of focal necrosis of the carapace.

Clinical Findings—Debridement revealed a 14.5 × 11.5-cm area of shell necrosis, deep abscess formation, and osteomyelitis involving bacterial (Klebsiella pneumoniae, Staphylococcus aureus, and Pseudomonas spp) and fungal pathogens.

Treatment and Outcome—Following extensive debridement, vacuum-assisted closure incorporating silver-impregnated bandaging materials was used. The wound was considered healed after 55 days, at which time a layer of epidermal tissue with progressing keratinization was present, with smooth underlying ossification. Keratinization with normal pigmentation continued over the next 67 days.

Clinical Relevance—Findings suggested that vacuum-assisted closure with silver-impreg-nated bandaging materials may provide advantages over traditional methods in the treatment of shell lesions in chelonians, including faster wound healing, improved cosmetic appearance of the healed wound, superior control of microbial contamination, and lower overall treatment costs.
