摘要：We understand, according to the bakhtinian perspective, that no fact of nature has meaning in itself, but the meaning just arises through language. Thus, the analysis of language helps to understand the ideological positions that support the discourses and consequently human practices. From this, we aim to comprehend how non-human animals (usually called guinea pigs) and the practices involving them, focused on laboratory experimentation, are perceived and presented by the scientific discourse genre, as well as how such a vision contributes to structure the relations we establish with them. For this, we analyzed a scientific article, using as category of analysis the notion of speech genres. We realize, in the analyzed text, the perspective that the use of animals is essential to the progress of science, so that any activity contrary to the performance of this practice is seen as radical and harmful to the scientific development.
