is a haematophagous mite of veterinary and public health concern. The association between O. bursa and humans in Brazil has been known for several decades, but most of the information is limited and confusing. Herein, we present an overview of the cases of gamasoidosis in Brazil based on published and new records. Wild birds are common sources for human infestation, especially omnivorous and insectivorous birds that live in urban and rural environments. Species of the Columbidae are the most common birds associated with O. bursa in Brazil. [ABSTRACT FROM AUTHOR]

Despite the broad celebration of Brazil's urban reform movement, recent events in Brazil have called attention to a paradox focused on the disappointing results of this movement to deal with Brazil's complex urban context. Taking this "impasse" as a starting point, this article focuses on the role of politics and its relationship to economic interests in urban development in which much decision making around urban policy takes place to understand why Brazil's progressive legislation has not succeeded in creating a more just and equitable urban environment. Using a case study of the city of Niterói, I show that patterns of state and nonstate actors are connected through both formal and informal relationships, and connections between public and private actors have a considerable impact on urban politics and policies. Focusing on the limits of participatory processes in Niterói, I call attention to the contradictions of participatory planning in Brazil. [ABSTRACT FROM AUTHOR]
