Miniature Pet Pig Behavioral Medicine.

Miniature pet pigs bond readily to people and can make excellent pets as long as they are given an appropriate environment and their behavioral needs are met. They are intelligent and highly social with a strong exploratory drive so, if they are not properly trained and their behavior directed appropriately, they can be destructive and even aggressive in some cases. Most problem behaviors are not a result of behavioral disorder but typically represent normal swine behaviors that people find unacceptable.

Entomophthoromycosis and mucormycosis as causes of pneumonia in Vietnamese potbellied pigs.

Two Vietnamese potbellied pigs ( Sus scrofa) had respiratory disease and, on autopsy, both pigs had large masses in the lungs and thoracic cavity. Microscopically, pulmonary and pleural masses contained large areas with hyphae surrounded by hypereosinophilic cellular debris rimmed by abundant eosinophils, lymphocytes, plasma cells, and histiocytes with occasional multinucleate giant cells. The hypereosinophilic debris usually formed tight cuffs, or "sleeves" around the hyphae, compatible with Splendore-Hoeppli-like material. The fungal organisms were determined by PCR to be Conidiobolus incongruus in one pig and Mucor circinelloides in the other. Entomophthoromycosis and mucormycosis should be included in the differential diagnoses for swine pneumonia, particularly when there is evidence of granulomatous pulmonary masses and pleural effusion with eosinophilic inflammation.

Exotic Companion Mammal Ambulatory Practice, Including Potbellied Pigs and Llamas.

An exotic companion animal ambulatory practice has unique challenges, advantages, and disadvantages. Not all veterinarians are suited to this type of practice, but it can be exceptionally rewarding. It can also be exceptionally frustrating. Ambulatory practice offers veterinary services to those clients who for a variety of reasons do not or cannot take their exotic companion animal, potbellied pig, or llama to a veterinary practice. Being able to observe husbandry and feeding practices and an animal's environment, the mobile veterinarian gets a more well-rounded picture of the patient.

Choriocarcinoma-like tumor in a potbellied pig (Sus scrofa).

A uterine tumor, with histological and immunohistochemical features consistent with those of human choriocarcinoma, was identified in a 10-year-old unmated female pot-bellied pig (Sus scrofa). The tumor showed biphasic proliferation of cytotrophoblast-like cells and syncytiotrophoblast-like cells. Immunohistochemically, the syncytiotrophoblast-like cells were positive for human chorionic gonadotropin, and both types of cells were positive for cytokeratin and negative for vimentin, octamer-binding transcription factor 4, and α-fetoprotein. Because syncytiotrophoblasts are absent in the normal porcine placenta, the tumor was diagnosed as a choriocarcinoma-like tumor.
