SEROLOGIC SURVEY FOR SELECTED INFECTIOUS DISEASES IN FREE-RANGING BRAZILIAN TAPIRS (TAPIRUS TERRESTRIS) IN THE CERRADO OF CENTRAL BRAZIL

From September 2000 to January 2002, a serologic survey was conducted in a population of free-ranging Brazilian tapirs (Tapirus terrestris) inhabiting Emas National Park and surrounding areas in Goias state. central Brazil, as part of an ecologic study. Ten tapirs were immobilized with a tiletamine-zolazepam combination. and blood samples were collected. All sera were negative for Leptospira spp.. Brucella abortus, and equine infectious anemia; and one of 10 animals was positive for Toxoplasma goudii. This report represents the first serologic survey for selected infectious diseases in a free-ranging population or Brazilians tapirs in central Brazil.

Maned Wolf Density in a Central Brazilian Grassland Reserve

The maned wolf (Chrysocyon brachyurus) inhabits the savannah-like Cerrado of Brazil. Although 80% of this biome has already been affected by human activity, little is known about maned wolf abundance. Using mark-recapture models, we obtained the first density estimate from central Brazil, the core of maned wolf distribution. With 5.19 individuals/100 km(2), even large reserves support only small maned wolf populations. Therefore, long-term conservation of the maned wolf depends on land management outside of reserves.

Central mucoepidermoid carcinoma: Report of a case with 11 years` evolution and peculiar macroscopical and clinical characteristics

Central mucoepidermoid carcinomas (CMC) are uncommon tumours, comprising 2-3% of all mucoepidermoid carcinomas reported. They have been reported in patients of all ages, ranging from 1 to 78-years, with the overwhelming majority occurring in the 4th and 5th decades of life. They are histologically low-grade cancers, usually affecting the mandible as uniocular or multiocular radiographic lesions. The authors report a case of CMC of the mandible with a long evolution, and peculiar clinical and macroscopical features related with the long term evolution of the disease. A 53-year-old male patient had expansion of buccal and lingual cortices of the anterior region of the mandible, covered by ulcerated mucosa, with 11 years evolution. An incisional biopsy was performed, and the histopathological findings confirm low-grade mucoepidermoid carcinoma. The patient was treated with a mandibulectomy, followed by supraomohyoid neck dissection. There was no evidence of local recurrence, regional or distant metastasis revealed; and the patient was alive and without disease after a follow-up interval of 36 months.
