RESUMOO objetivo do presente trabalho foi determinar a frequência de propriedades positivas (focos) e de fêmeas bovinas soropositivas para a brucelose no Estado de Roraima, bem como identificar fatores de risco. Foram utilizados dados da Agência de Defesa Agropecuária do Estado de Roraima (ADERR), coletados de suas quatro microrregiões, durante o período de janeiro de 2007 a julho de 2009. Durante esse período, foram examinadas 387 propriedades, e 9.087 soros de fêmeas bovinas com idade ≥ 24 meses foram submetidos ao diagnóstico sorológico da brucelose. Para a análise de fatores de risco, foi utilizada a regressão logística múltipla. Uma propriedade foi considerada foco quando apresentou pelo menos um animal soropositivo. Das propriedades investigadas, 106 (27,4%) apresentaram pelo menos um animal soropositivo e, dos animais analisados, 369 (4,1%) foram soropositivos. Os fatores de risco identificados foram: possuir mais de 51 animais no rebanho (odds ratio = 1,87; p = 0,015) e alugar pasto (odds ratio = 2,20; p = 0,003). Sugere-se que esforços sejam concentrados na intensificação da vacinação de bezerras no Estado de Roraima com o intuito de que seja alcançada uma prevalência compatível com as ações de teste e sacrifício de animais.

The aim of this study was to determine the frequency of positive herds (foci) and seropositive bovine females for brucellosis in the state of Roraima, Northern region of Brazil, as well as to identify risk factors. Data from the Agency of Agricultural Protection in the state, collected from its four microregions during the January 2007 to July 2009 period, were used. During this period, 387 herds were examined, and 9,087 adult bovine female sera were submitted to the serological diagnosis of brucellosis. For risk factor analysis the multiple logistic regression was used. A herd was considered focus when presented at least one seropositive animal. Of the herds investigated, 106 (27.4%) had at least one seropositive animal, and of the animals examined, 369 (4.1%) were seropositive. Risk factors identified were: herd size larger than 51 animals (odds ratio = 1.87; p = 0.015) and pasture rental (odds ratio = 2.20; p = 0.003). It is suggested that efforts must be concentrated on the intensification of heifer vaccination in the State of Roraima in order to reach a prevalence value compatible with actions of test and sacrifice of animals.
Epithelioma cuniculatum, a rare form of squamous cell carcinoma affecting the sole of the foot, was observed in 2 male patients aged 62 and 69 years, respectively. In each case the lesion consisted of a fungating mass with sinuses draining foul-smelling fluid with keratin debris.
Summary The first human case of dermatophilosis occurring in Brazil is reported. Zusammenfassung Der erste Fall von Dermatophilose beim Menschen in Brasilien wird mitgeteilt. Resumo É descrito o primeiro caso humano de dermatofilose ocorrido no Brasil. Resumen Se relata el primer caso de dermatofilosis humana en Brasil.
