Sporotrichosis in a Pacific white-sided dolphin (Lagenorhynchus obliquidens).

A severe necrotizing granulomatous lymphadenitis caused by Sporothrix schenckii was diagnosed in a Pacific white-sided dolphin (Lagenorhynchus obliquidens) that had been in captivity for about 3 years. Histopathologic and electron microscopic studies, as well as fluorescent antibody techniques, were used to identify S schenckii as the etiologic agent.

Renal adenoma in an Atlantic bottle-nosed dolphin (Tursiops truncatus).

A solitary renal adenoma was an incidental finding at the pole of a kidney of an aged male Atlantic bottle-nosed dolphin (Tursiops truncatus) which had been captured in the Gulf of Mexico near St. Petersburg Beach, Fla, and maintained at Marine Attractions, Inc, St. Petersburg. The only other significant findings were widespread cutaneous lesions of Lobo disease.

Toxoplasmosis in a California sea lion (Zalophus californianus).

Disseminated toxoplasmosis was diagnosed in a female California sea lion that had been used in thermoregulation studies for about 4 years while housed in a small enclosure with a fresh-water pool at the University of Hawaii, Honolulu. Toxoplasma gondii was demonstrated in and around necrotic lesions of the heart and the stomach. Source of the infection was not established; however, studies on toxoplasmosis in cats were being conducted at the institution, and common caretakers attended both groups of animals.

Systemic mycoses in marine mammals.

Thirty-four cases of systemic mycosis in marine mammals were represented by 9 genera of fungi. All cases were characterized by pulmonary involvement, with miliary spread to abdominal organs. Cases were geographically distributed among Hawaii, northern United States, Europe, New Zealand, and southern Asia.

Actinomycetales Infections↗

Cerebral abscess associated with stranding in a dolphin.

A captive Atlantic bottlenosed dolphin (Tursiops truncatus) was examined after being found beached in the shallows of its lagoon enclosure. An abscess was found in the right cerebral hemisphere, and Staphylococcus aureus was isolated from the lesion. Histopathologic examination of the brain revealed a pyogenic meningoencephalitis.

Animals↗

Myeloliposarcoma in a potto (Perodicticus potto): a case report.

A female Perodicticus potto developed a subcutaneous spherical mass on the medial aspect of the inguinal area. The anesthesia, surgical removal, and aftercare were described. The tumor was described grossly and histologically. It was determined to be a myeloliposarcoma. The tumor has not recurred after 14 mo.

Animals↗

Dermatophilosis in a titi monkey (Callicebus moloch).

The occurrence of dermatophilosis in the titi monkey is reported. Lesions were principally in the epidermis of the skin and were characterized by parakeratosis, necrosis, abscess formation, acanthosis, and hyperkeratosis. The cause, Dermatophilus congolensis, was demonstrated as a gram-positive filamentous organism with both horizontal and vertical septums.

Actinomycetales Infections↗

Mycotic granuloma in a tiger salamander.

An unidentified brown-pigmented fungus was the cause of a granuloma in the left lumbar musculature of a captive female tiger salamander. Histologically, the fungus appeared in the granulomatous tissue both as round yeastlike budding cells and as long septate hyphae.

Shrews: a review of the diseases, anomalies, and parasites.

The diseases, lesions, congenital disorders, and parasites of both Insectivora and prosimian shrews were reviewed. Preliminary baseline data provide encouraging prospects for using these animals as research models because few spontaneous diseases and lesions have been reported. It must be pointed out, however, that throughout the literature reviewed, clinical histories were incomplete and histopathologic examinations had seldom been performed, particularly with the parasitic entities.
