O uso de plantas pode ser considerado uma das formas mais antigas de práticas terapêuticas. Com base nessa afirmação, o presente artigo buscou descrever os principais fatos históricos relativos à utilização de plantas medicinais desde a pré-história até a atualidade. O objetivo do trabalho foi a realização de um levantamento bibliográfico sobre o histórico de uso de plantas medicinais e a sua relevância frente a implementação de políticas públicas de saúde. A pesquisa foi realizada de setembro a outubro de 2020, sendo analisados artigos e dissertações presentes em bases de dados específicas (Schoolar Google, Science Direct e Pubmed). Ao término do estudo pode-se perceber a fundamental importância dos saberes populares presentes em diferentes culturas, como fator essencial a construção e implementação políticas sólidas de saúde, de âmbito nacional, como o Sistema Único de Saúde (SUS) e a Política Nacional de Plantas Medicinais e Fitoterápicos (PNPMF).

Due to their mass production and intense consumption in human medicine, veterinary, and aquaculture, antibiotics have been widely detected in different ecosystems, leading to a growing worldwide concern. These and their byproducts are being continuously discarded in natural ecosystems via excretion of human and animal urine and feces, also domestic and hospital effluents. Residues of these drugs can persist in natural environments through bioaccumulation due to their difficult biodegradation. Also, they have a gradual deposition in sediments, aquatic surfaces, and groundwater. Studies have shown the presence of these drugs in aquatic environments, which can trigger severe changes in the composition and structure of the bacterial community, such as the ability to develop and propagate genes resistant to these pollutants. In this context, this review aims to address the effects of the antibiotics on microorganisms present in impacted aquatic environments.

Objectives: The research objective was to present the main techniques for identifying pathogenic microorganisms and the application of new technologies for the clinical diagnosis of infectious diseases. Methods: It was made a search for free and recent journals available online in the databases of Pubmed (National Library of Medicine and the National Institutes), Lilacs (Latin American and Caribbean Literature in Health Sciences), and Scielo (Scientific Electronic Library Online), based on keywords related to the proposed theme. Results: From the researched literature, it was possible to verify that conventional techniques, despite their limitations, are still widely used for the identification and microbial characterization. However, in the last decades, molecular methods have been widely inserted in the laboratory routine seeking to increase the capacity to detect infectious agents with high sensitivity, specificity, speed, and low cost. Among the various techniques, amplification of DNA sequences is highlighted by the polymerase chain reaction (PCR), the sequencing of the 16S rRNA gene, and other variations of PCR. In addition to these, new technologies have been developed, such as new generation sequencing (NGS) and Matrix-assisted Laser Desorption/ionization-time-of-flight Mass Spectrometry (MALDI-TOF MS). Conclusion: The development of new technologies that allow rapid, sensitive, reproducible, and low-cost microbial identification, it is of great relevance for clinical microbiology, and consequently, for public health.
