ABSTRACT
In Brazil, rabies occurs mainly within an urban cycle, in which dogs and bats are reservoirs. This paper aims to report the occurrence of rabies in Callithrix sp. in Niterói, Rio de Janeiro, Brazil. In June 2019 a hybrid specimen was referred for diagnosis. The Direct Fluorescent Antibody, Mouse Inoculation, and Polymerase Chain Reaction tests were positive. A phylogenetic analysis was compatible with antigenic variant 3, characteristic of Desmodus rotundus. New studies should be undertaken to elucidate the real role of callitrichids in the urban rabies cycle.

The inter-relations between man and the environment are among the main themes currently debated by the Brazilian public health. On such horizon, the questions concerning Chagas's disease are found to remain specially in the scope of the directed actions of control to the triatomine, the anti-vectorial fight , though already a century since its first description by Carlos Chagas, a major epidemiological problem in Latin America. Based on these considerations the present article will seek to discuss the main ecological aspects related to the American trypanosomiasis, emphasizing the control of the vectorial transmission in the context of the deep ecology.

As inter-relações entre o homem e o meio ambiente estão entre os principais temas debatidos no contexto atual da saúde pública brasileira. Neste horizonte se inscrevem as questões atinentes à moléstia de Chagas especialmente no âmbito das ações de controle dirigidas aos triatomíneos, a luta antivetorial , a qual permanece, mesmo após quase um século de sua descrição por Carlos Chagas, como uma condição de grande impacto epidemiológico na América Latina. Com base nestas considerações, o presente artigo buscará discutir os principais aspectos ecológicos relacionados à tripanossomíase americana em um esforço de delimitação da questão, muito mais do que proposição de respostas , enfatizando-se o controle da transmissão vetorial, repensada em termos da ecologia profunda.

A paragonimíase é uma doença zoonótica, não-contagiosa, produzida por trematódeos do gênero Paragonimus. O homem e outros animais infectam-se ao ingerir crustáceos de água doce crus, mal cozidos ou em conserva ou, ainda, água e/ou alimentos contaminados com metacercárias. Apresenta evolução crônica e acometimento predominantemente pulmonar, ainda que sejam descritas descritas alterações extrapulmonares. Podem surgir sinais e sintomas como tosse com expectoração sanguinolenta, febre intermitente, dor torácica, suores noturnos e, mais raramente, astenia, anorexia e perda de peso. Como principais métodos diagnósticos destacam-se o exame a fresco do escarro e/ou das fezes do paciente e os testes imunológicos. O tratamento é realizado com praziquantel. A infecção, habitualmente, tem bom prognóstico.
